<h2 id="about">About rclone</h2>
<p>Rclone is a command-line program to manage files on cloud storage. It
is a feature-rich alternative to cloud vendors' web storage interfaces.
<a href="#providers">Over 70 cloud storage products</a> support rclone
including S3 object stores, business &amp; consumer file storage
services, as well as standard transfer protocols.</p>
<p>Rclone has powerful cloud equivalents to the unix commands rsync, cp,
mv, mount, ls, ncdu, tree, rm, and cat. Rclone's familiar syntax
includes shell pipeline support, and <code>--dry-run</code> protection.
It is used at the command line, in scripts or via its <a
href="/rc">API</a>.</p>
<p>Users call rclone <em>"The Swiss army knife of cloud storage"</em>,
and <em>"Technology indistinguishable from magic"</em>.</p>
<p>Rclone really looks after your data. It preserves timestamps and
verifies checksums at all times. Transfers over limited bandwidth;
intermittent connections, or subject to quota can be restarted, from the
last good file transferred. You can <a
href="https://rclone.org/commands/rclone_check/">check</a> the integrity
of your files. Where possible, rclone employs server-side transfers to
minimise local bandwidth use and transfers from one provider to another
without using local disk.</p>
<p>Virtual backends wrap local and cloud file systems to apply <a
href="https://rclone.org/crypt/">encryption</a>, <a
href="https://rclone.org/compress/">compression</a>, <a
href="https://rclone.org/chunker/">chunking</a>, <a
href="https://rclone.org/hasher/">hashing</a> and <a
href="https://rclone.org/union/">joining</a>.</p>
<p>Rclone <a href="https://rclone.org/commands/rclone_mount/">mounts</a>
any local, cloud or virtual filesystem as a disk on Windows, macOS,
linux and FreeBSD, and also serves these over <a
href="https://rclone.org/commands/rclone_serve_sftp/">SFTP</a>, <a
href="https://rclone.org/commands/rclone_serve_http/">HTTP</a>, <a
href="https://rclone.org/commands/rclone_serve_webdav/">WebDAV</a>, <a
href="https://rclone.org/commands/rclone_serve_ftp/">FTP</a> and <a
href="https://rclone.org/commands/rclone_serve_dlna/">DLNA</a>.</p>
<p>Rclone is mature, open-source software originally inspired by rsync
and written in <a href="https://golang.org">Go</a>. The friendly support
community is familiar with varied use cases. Official Ubuntu, Debian,
Fedora, Brew and Chocolatey repos. include rclone. For the latest
version <a href="https://rclone.org/downloads/">downloading from
rclone.org</a> is recommended.</p>
<p>Rclone is widely used on Linux, Windows and Mac. Third-party
developers create innovative backup, restore, GUI and business process
solutions using the rclone command line or API.</p>
<p>Rclone does the heavy lifting of communicating with cloud
storage.</p>

<p>Many Linux, Windows, macOS and other OS distributions package and
distribute rclone.</p>
<p>The distributed versions of rclone are often quite out of date and
for this reason we recommend one of the other installation methods if
possible.</p>
<p>You can get an idea of how up to date or not your OS distribution's

<h2 id="docker">Docker installation</h2>
<p>The rclone developers maintain a <a
href="https://hub.docker.com/r/rclone/rclone">docker image for
rclone</a>.</p>
<p><strong>Note:</strong> We also now offer a paid version of rclone
with enterprise-grade security and zero CVEs through our partner <a
href="https://securebuild.com/blog/introducing-securebuild">SecureBuild</a>.
If you are interested, check out their website and the <a
href="https://securebuild.com/images/rclone">Rclone SecureBuild
Image</a>.</p>
<p>These images are built as part of the release process based on a
minimal Alpine Linux.</p>
<p>The <code>:latest</code> tag will always point to the latest stable
release. You can use the <code>:beta</code> tag to get the latest build
from master. You can also use version tags, e.g. <code>:1.49.1</code>,
<code>:1.49</code> or <code>:1</code>.</p>
<pre class="console"><code>$ docker pull rclone/rclone:latest
latest: Pulling from rclone/rclone
Digest: sha256:0e0ced72671989bb837fea8e88578b3fc48371aa45d209663683e24cfdaa0e11
...
$ docker run --rm rclone/rclone:latest version
rclone v1.49.1
- os/arch: linux/amd64
- go version: go1.12.9</code></pre>
<p>There are a few command line options to consider when starting an
rclone Docker container from the rclone image.</p>
<ul>
<li><p>You need to mount the host rclone config dir at
<code>/config/rclone</code> into the Docker container. Due to the fact
that rclone updates tokens inside its config file, and that the update
process involves a file rename, you need to mount the whole host rclone
config dir, not just the single host rclone config file.</p></li>
<li><p>You need to mount a host data dir at <code>/data</code> into the
Docker container.</p></li>
<li><p>By default, the rclone binary inside a Docker container runs with
UID=0 (root). As a result, all files created in a run will have UID=0.
If your config and data files reside on the host with a non-root
UID:GID, you need to pass these on the container start command
line.</p></li>
<li><p>If you want to access the RC interface (either via the API or the
Web UI), it is required to set the <code>--rc-addr</code> to
<code>:5572</code> in order to connect to it from outside the container.
An explanation about why this is necessary can be found in an old <a
href="https://web.archive.org/web/20200808071950/https://pythonspeed.com/articles/docker-connection-refused/">pythonspeed.com</a>
article.</p>
<ul>
<li>NOTE: Users running this container with the docker network set to
<code>host</code> should probably set it to listen to localhost only,
with <code>127.0.0.1:5572</code> as the value for
<code>--rc-addr</code></li>
</ul></li>
<li><p>It is possible to use <code>rclone mount</code> inside a
userspace Docker container, and expose the resulting fuse mount to the
host. The exact <code>docker run</code> options to do that might vary
slightly between hosts. See, e.g. the discussion in this <a
href="https://github.com/moby/moby/issues/9448">thread</a>.</p>
<p>You also need to mount the host <code>/etc/passwd</code> and
<code>/etc/group</code> for fuse to work inside the container.</p></li>
</ul>

<p><a href="https://snapcraft.io/rclone"><img
src="https://snapcraft.io/rclone/badge.svg" alt="rclone" /></a></p>
<h2 id="source">Source installation</h2>
<p>Make sure you have git and <a href="https://golang.org/">Go</a>
installed. Go version 1.24 or newer is required, the latest release is
recommended. You can get it from your package manager, or download it
from <a href="https://golang.org/dl/">golang.org/dl</a>. Then you can
run the following:</p>
<pre class="console"><code>git clone https://github.com/rclone/rclone.git
cd rclone
go build</code></pre>
<p>This will check out the rclone source in subfolder rclone, which you
can later modify and send pull requests with. Then it will build the
rclone executable in the same folder. As an initial check you can now
run <code>./rclone version</code> (<code>.\rclone version</code> on
Windows).</p>
<p>Note that on macOS and Windows the <a
href="https://rclone.org/commands/rclone_mount/">mount</a> command will
not be available unless you specify an additional build tag
<code>cmount</code>.</p>
<pre class="console"><code>go build -tags cmount</code></pre>
<p>This assumes you have a GCC compatible C compiler (GCC or Clang) in
your PATH, as it uses <a href="https://pkg.go.dev/cmd/cgo">cgo</a>. But
on Windows, the <a href="https://github.com/winfsp/cgofuse">cgofuse</a>
library that the cmount implementation is based on, also supports
building <a href="https://github.com/golang/go/wiki/WindowsDLLs">without
cgo</a>, i.e. by setting environment variable CGO_ENABLED to value 0
(static linking). This is how the official Windows release of rclone is
being built, starting with version 1.59. It is still possible to build
with cgo on Windows as well, by using the MinGW port of GCC, e.g. by
installing it in a <a href="https://www.msys2.org">MSYS2</a>
distribution (make sure you install it in the classic mingw64 subsystem,
the ucrt64 version is not compatible).</p>
<p>Additionally, to build with mount on Windows, you must install the
third party utility <a href="https://winfsp.dev/">WinFsp</a>, with the
"Developer" feature selected. If building with cgo, you must also set
environment variable CPATH pointing to the fuse include directory within
the WinFsp installation (normally
<code>C:\Program Files (x86)\WinFsp\inc\fuse</code>).</p>
<p>You may add arguments <code>-ldflags -s</code> to omit symbol table
and debug information, making the executable file smaller, and
<code>-trimpath</code> to remove references to local file system paths.
The official rclone releases are built with both of these.</p>
<pre class="console"><code>go build -trimpath -ldflags -s -tags cmount</code></pre>
<p>If you want to customize the version string, as reported by the
<code>rclone version</code> command, you can set one of the variables
<code>fs.Version</code>, <code>fs.VersionTag</code> (to keep default
suffix but customize the number), or <code>fs.VersionSuffix</code> (to
keep default number but customize the suffix). This can be done from the
build command, by adding to the <code>-ldflags</code> argument value as
shown below.</p>
<pre class="console"><code>go build -trimpath -ldflags &quot;-s -X github.com/rclone/rclone/fs.Version=v9.9.9-test&quot; -tags cmount</code></pre>
<p>On Windows, the official executables also have the version
information, as well as a file icon, embedded as binary resources. To
get that with your own build you need to run the following command
<strong>before</strong> the build command. It generates a Windows
resource system object file, with extension .syso, e.g.
<code>resource_windows_amd64.syso</code>, that will be automatically
picked up by future build commands.</p>
<pre class="console"><code>go run bin/resource_windows.go</code></pre>
<p>The above command will generate a resource file containing version
information based on the fs.Version variable in source at the time you
run the command, which means if the value of this variable changes you
need to re-run the command for it to be reflected in the version
information. Also, if you override this version variable in the build
command as described above, you need to do that also when generating the
resource file, or else it will still use the value from the source.</p>
<pre class="console"><code>go run bin/resource_windows.go -version v9.9.9-test</code></pre>
<p>Instead of executing the <code>go build</code> command directly, you
can run it via the Makefile. The default target changes the version
suffix from "-DEV" to "-beta" followed by additional commit details,
embeds version information binary resources on Windows, and copies the
resulting rclone executable into your GOPATH bin folder
(<code>$(go env GOPATH)/bin</code>, which corresponds to
<code>~/go/bin/rclone</code> by default).</p>
<pre class="console"><code>make</code></pre>
<p>To include mount command on macOS and Windows with Makefile
build:</p>
<pre class="console"><code>make GOTAGS=cmount</code></pre>
<p>There are other make targets that can be used for more advanced
builds, such as cross-compiling for all supported os/architectures, and
packaging results into release artifacts. See <a
href="https://github.com/rclone/rclone/blob/master/Makefile">Makefile</a>
and <a
href="https://github.com/rclone/rclone/blob/master/bin/cross-compile.go">cross-compile.go</a>
for details.</p>
<p>Another alternative method for source installation is to download the
source, build and install rclone - all in one operation, as a regular Go
package. The source will be stored it in the Go module cache, and the
resulting executable will be in your GOPATH bin folder
(<code>$(go env GOPATH)/bin</code>, which corresponds to
<code>~/go/bin/rclone</code> by default).</p>
<pre class="console"><code>go install github.com/rclone/rclone@latest</code></pre>
<p>In some situations, rclone executable size might be too big for
deployment in very restricted environments when all backends with large
SDKs are included. To limit binary size unused backends can be commented
out in <code>backends/all/all.go</code> and unused commands in
<code>cmd/all/all.go</code> before building with <code>go build</code>
or <code>make</code></p>

<h2 id="portable">Portable installation</h2>
<p>As mentioned <a
href="https://rclone.org/install/#quickstart">above</a>, rclone is
single executable (<code>rclone</code>, or <code>rclone.exe</code> on
Windows) that you can download as a zip archive and extract into a
location of your choosing. When executing different commands, it may
create files in different locations, such as a configuration file and
various temporary files. By default the locations for these are
according to your operating system, e.g. configuration file in your user
profile directory and temporary files in the standard temporary
directory, but you can customize all of them, e.g. to make a completely
self-contained, portable installation.</p>
<p>Run the <a
href="https://rclone.org/commands/rclone_config_paths/">config paths</a>
command to see the locations that rclone will use.</p>
<p>To override them set the corresponding options (as command-line
arguments, or as <a

</ul>
<h2 id="autostart">Autostart</h2>
<p>After installing and configuring rclone, as described above, you are
ready to use rclone as an interactive command line utility. If your goal
is to perform <em>periodic</em> operations, such as a regular <a
href="https://rclone.org/commands/rclone_sync/">sync</a>, you will
probably want to configure your rclone command in your operating
system's scheduler. If you need to expose <em>service</em>-like
features, such as <a href="https://rclone.org/rc/">remote control</a>,
<a href="https://rclone.org/gui/">GUI</a>, <a
href="https://rclone.org/commands/rclone_serve/">serve</a> or <a
href="https://rclone.org/commands/rclone_mount/">mount</a>, you will
often want an rclone command always running in the background, and
configuring it to run in a service infrastructure may be a better
option. Below are some alternatives on how to achieve this on different
operating systems.</p>
<p>NOTE: Before setting up autorun it is highly recommended that you
have tested your command manually from a Command Prompt first.</p>
<h3 id="autostart-on-windows">Autostart on Windows</h3>
<p>The most relevant alternatives for autostart on Windows are:</p>
<ul>
<li>Run at user log on using the Startup folder</li>
<li>Run at user log on, at system startup or at schedule using Task
Scheduler</li>
<li>Run at system startup using Windows service</li>
</ul>
<h4 id="running-in-background">Running in background</h4>
<p>Rclone is a console application, so if not starting from an existing
Command Prompt, e.g. when starting rclone.exe from a shortcut, it will
open a Command Prompt window. When configuring rclone to run from task
scheduler and windows service you are able to set it to run hidden in
background. From rclone version 1.54 you can also make it run hidden
from anywhere by adding option <code>--no-console</code> (it may still
flash briefly when the program starts). Since rclone normally writes
information and any error messages to the console, you must redirect
this to a file to be able to see it. Rclone has a built-in option
<code>--log-file</code> for that.</p>
<p>Example command to run a sync in background:</p>
<div class="sourceCode" id="cb35"><pre
class="sourceCode bat"><code class="sourceCode dosbat"><span id="cb35-1"><a href="#cb35-1" aria-hidden="true" tabindex="-1"></a>c:\rclone\rclone.exe sync c:\files remote:<span class="at">/files</span> -<span class="at">-no-console</span> -<span class="at">-log-file</span> c:\rclone\logs\sync_files.txt</span></code></pre></div>
<h4 id="user-account">User account</h4>
<p>As mentioned in the <a
href="https://rclone.org/commands/rclone_mount/">mount</a>
documentation, mounted drives created as Administrator are not visible
to other accounts, not even the account that was elevated as
Administrator. By running the mount command as the built-in
<code>SYSTEM</code> user account, it will create drives accessible for
everyone on the system. Both scheduled task and Windows service can be
used to achieve this.</p>
<p>NOTE: Remember that when rclone runs as the <code>SYSTEM</code> user,
the user profile that it sees will not be yours. This means that if you
normally run rclone with configuration file in the default location, to
be able to use the same configuration when running as the system user
you must explicitly tell rclone where to find it with the <a
href="https://rclone.org/docs/#config-string"><code>--config</code></a>
option, or else it will look in the system users profile path
(<code>C:\Windows\System32\config\systemprofile</code>). To test your
command manually from a Command Prompt, you can run it with the <a
href="https://docs.microsoft.com/en-us/sysinternals/downloads/psexec">PsExec</a>
utility from Microsoft's Sysinternals suite, which takes option
<code>-s</code> to execute commands as the <code>SYSTEM</code> user.</p>
<h4 id="start-from-startup-folder">Start from Startup folder</h4>
<p>To quickly execute an rclone command you can simply create a standard
Windows Explorer shortcut for the complete rclone command you want to
run. If you store this shortcut in the special "Startup" start-menu
folder, Windows will automatically run it at login. To open this folder
in Windows Explorer, enter path
<code>%APPDATA%\Microsoft\Windows\Start Menu\Programs\Startup</code>, or
<code>C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp</code>
if you want the command to start for <em>every</em> user that logs
in.</p>
<p>This is the easiest approach to autostarting of rclone, but it offers
no functionality to set it to run as different user, or to set
conditions or actions on certain events. Setting up a scheduled task as
described below will often give you better results.</p>
<h4 id="start-from-task-scheduler">Start from Task Scheduler</h4>
<p>Task Scheduler is an administrative tool built into Windows, and it
can be used to configure rclone to be started automatically in a highly
configurable way, e.g. periodically on a schedule, on user log on, or at
system startup. It can run be configured to run as the current user, or
for a mount command that needs to be available to all users it can run
as the <code>SYSTEM</code> user. For technical information, see <a
href="https://docs.microsoft.com/windows/win32/taskschd/task-scheduler-start-page">Task
Scheduler for developers</a>.</p>
<h4 id="run-as-service">Run as service</h4>
<p>For running rclone at system startup, you can create a Windows
service that executes your rclone command, as an alternative to
scheduled task configured to run at startup.</p>
<h5 id="mount-command-built-in-service-integration">Mount command
built-in service integration</h5>
<p>For mount commands, rclone has a built-in Windows service integration
via the third-party WinFsp library it uses. Registering as a regular
Windows service easy, as you just have to execute the built-in
PowerShell command <code>New-Service</code> (requires administrative
privileges).</p>
<p>Example of a PowerShell command that creates a Windows service for
mounting some <code>remote:/files</code> as drive letter
<code>X:</code>, for <em>all</em> users (service will be running as the
local system account):</p>
<div class="sourceCode" id="cb36"><pre
class="sourceCode powershell"><code class="sourceCode powershell"><span id="cb36-1"><a href="#cb36-1" aria-hidden="true" tabindex="-1"></a><span class="fu">New-Service</span> <span class="op">-</span>Name Rclone <span class="op">-</span>BinaryPathName <span class="st">&#39;c:\rclone\rclone.exe mount remote:/files X: --config c:\rclone\config\rclone.conf --log-file c:\rclone\logs\mount.txt&#39;</span></span></code></pre></div>
<p>The <a
href="https://github.com/billziss-gh/winfsp/wiki/WinFsp-Service-Architecture">WinFsp
service infrastructure</a> supports incorporating services for file
system implementations, such as rclone, into its own launcher service,
as kind of "child services". This has the additional advantage that it
also implements a network provider that integrates into Windows standard
methods for managing network drives. This is currently not officially
supported by Rclone, but with WinFsp version 2019.3 B2 / v1.5B2 or later
it should be possible through path rewriting as described in <a
href="https://github.com/rclone/rclone/issues/3340">#3340</a>.</p>
<h5 id="third-party-service-integration">Third-party service
integration</h5>
<p>To Windows service running any rclone command, the excellent
third-party utility <a href="http://nssm.cc">NSSM</a>, the "Non-Sucking
Service Manager", can be used. It includes some advanced features such
as adjusting process priority, defining process environment variables,
redirect to file anything written to stdout, and customized response to
different exit codes, with a GUI to configure everything from (although
it can also be used from command line ).</p>
<p>There are also several other alternatives. To mention one more, <a
href="https://github.com/winsw/winsw">WinSW</a>, "Windows Service
Wrapper", is worth checking out. It requires .NET Framework, but it is
preinstalled on newer versions of Windows, and it also provides
alternative standalone distributions which includes necessary runtime
(.NET 5). WinSW is a command-line only utility, where you have to
manually create an XML file with service configuration. This may be a
drawback for some, but it can also be an advantage as it is easy to back
up and reuse the configuration settings, without having go through
manual steps in a GUI. One thing to note is that by default it does not
restart the service on error, one have to explicit enable this in the
configuration file (via the "onfailure" parameter).</p>
<h3 id="autostart-on-linux">Autostart on Linux</h3>
<h4 id="start-as-a-service">Start as a service</h4>
<p>To always run rclone in background, relevant for mount commands etc,
you can use systemd to set up rclone as a system or user service.
Running as a system service ensures that it is run at startup even if
the user it is running as has no active session. Running rclone as a
user service ensures that it only starts after the configured user has
logged into the system.</p>
<h4 id="run-periodically-from-cron">Run periodically from cron</h4>
<p>To run a periodic command, such as a copy/sync, you can set up a cron
job.</p>

<h2 id="basic-syntax">Basic syntax</h2>
<p>Rclone syncs a directory tree from one storage system to another.</p>
<p>Its syntax is like this</p>
<pre class="console"><code>rclone subcommand [options] &lt;parameters&gt; &lt;parameters...&gt;</code></pre>
<p>A <code>subcommand</code> is an rclone operation required (e.g.
<code>sync</code>, <code>copy</code>, <code>ls</code>).</p>
<p>An <code>option</code> is a single letter flag (e.g. <code>-v</code>)
or a group of single letter flags (e.g. <code>-Pv</code>) or a long flag
(e.g. <code>--progress</code>). No options are required. Options can
come after the <code>subcommand</code> or in between parameters too or
on the end, but only global options can be used before the
<code>subcommand</code>. Anything after a <code>--</code> option will
not be interpreted as an option so if you need to add a parameter which
starts with a <code>-</code> then put a <code>--</code> on its own
first, eg</p>
<pre class="console"><code>rclone lsf -- -directory-starting-with-dash</code></pre>
<p>A <code>parameter</code> is usually a file path or <a
href="#syntax-of-remote-paths">rclone remote</a>, eg
<code>/path/to/file</code> or <code>remote:path/to/file</code> but it
can be other things - the <code>subcommand</code> help will tell you
what.</p>
<p>Source and destination paths are specified by the name you gave the
storage system in the config file then the sub path, e.g.
"drive:myfolder" to look at "myfolder" in Google drive.</p>
<p>You can define as many storage paths as you like in the config
file.</p>
<p>Please use the <a
href="#interactive"><code>--interactive</code>/<code>-i</code></a> flag
while learning rclone to avoid accidental data loss.</p>
<h2 id="subcommands">Subcommands</h2>
<p>rclone uses a system of subcommands. For example</p>
<pre class="console"><code>rclone ls remote:path # lists a remote
rclone copy /local/path remote:path # copies /local/path to the remote
rclone sync --interactive /local/path remote:path # syncs /local/path to the remote</code></pre>

<h1 id="rclone-copy">rclone copy</h1>
<p>Copy files from source to dest, skipping identical files.</p>
<h2 id="synopsis-2">Synopsis</h2>
<p>Copy the source to the destination. Does not transfer files that are
identical on source and destination, testing by size and modification
time or MD5SUM. Doesn't delete files from the destination. If you want
to also delete files from destination, to make it match source, use the
<a href="https://rclone.org/commands/rclone_sync/">sync</a> command
instead.</p>
<p>Note that it is always the contents of the directory that is synced,
not the directory itself. So when source:path is a directory, it's the
contents of source:path that are copied, not the directory name and
contents.</p>
<p>To copy single files, use the <a
href="https://rclone.org/commands/rclone_copyto/">copyto</a> command
instead.</p>
<p>If dest:path doesn't exist, it is created and the source:path
contents go there.</p>
<p>For example</p>
<div class="sourceCode" id="cb43"><pre
class="sourceCode sh"><code class="sourceCode bash"><span id="cb43-1"><a href="#cb43-1" aria-hidden="true" tabindex="-1"></a><span class="ex">rclone</span> copy source:sourcepath dest:destpath</span></code></pre></div>
<p>Let's say there are two files in sourcepath</p>
<pre class="text"><code>sourcepath/one.txt
sourcepath/two.txt</code></pre>
<p>This copies them to</p>
<pre class="text"><code>destpath/one.txt
destpath/two.txt</code></pre>
<p>Not to</p>

<p>If you are familiar with <code>rsync</code>, rclone always works as
if you had written a trailing <code>/</code> - meaning "copy the
contents of this directory". This applies to all commands and whether
you are talking about the source or destination.</p>
<p>See the <a
href="https://rclone.org/docs/#no-traverse">--no-traverse</a> option for
controlling whether rclone lists the destination directory or not.
Supplying this option when copying a small number of files into a large
destination can speed transfers up greatly.</p>
<p>For example, if you have many files in /path/to/src but only a few of
them change every day, you can copy all the files which have changed
recently very efficiently like this:</p>
<div class="sourceCode" id="cb47"><pre
class="sourceCode sh"><code class="sourceCode bash"><span id="cb47-1"><a href="#cb47-1" aria-hidden="true" tabindex="-1"></a><span class="ex">rclone</span> copy <span class="at">--max-age</span> 24h <span class="at">--no-traverse</span> /path/to/src remote:</span></code></pre></div>
<p>Rclone will sync the modification times of files and directories if
the backend supports it. If metadata syncing is required then use the
<code>--metadata</code> flag.</p>
<p>Note that the modification time and metadata for the root directory
will <strong>not</strong> be synced. See <a
href="https://github.com/rclone/rclone/issues/7652">issue #7652</a> for
more info.</p>
<p><strong>Note</strong>: Use the
<code>-P</code>/<code>--progress</code> flag to view real-time transfer
statistics.</p>
<p><strong>Note</strong>: Use the <code>--dry-run</code> or the
<code>--interactive</code>/<code>-i</code> flag to test without copying
anything.</p>
<h2 id="logger-flags">Logger Flags</h2>
<p>The <code>--differ</code>, <code>--missing-on-dst</code>,
<code>--missing-on-src</code>, <code>--match</code> and
<code>--error</code> flags write paths, one per line, to the file name
(or stdout if it is <code>-</code>) supplied. What they write is
described in the help below. For example <code>--differ</code> will
write all paths which are present on both the source and destination but
different.</p>
<p>The <code>--combined</code> flag will write a file (or stdout) which
contains all file paths with a symbol and then a space and then the path
to tell you what happened to it. These are reminiscent of diff
files.</p>
<ul>
<li><code>= path</code> means path was found in source and destination
and was identical</li>
<li><code>- path</code> means path was missing on the source, so only in
the destination</li>
<li><code>+ path</code> means path was missing on the destination, so
only in the source</li>
<li><code>* path</code> means path was present in source and destination
but different.</li>
<li><code>! path</code> means there was an error reading or hashing the
source or dest.</li>
</ul>
<p>The <code>--dest-after</code> flag writes a list file using the same
format flags as <a
href="https://rclone.org/commands/rclone_lsf/#synopsis"><code>lsf</code></a>
(including <a
href="https://rclone.org/commands/rclone_lsf/#synopsis">customizable
options for hash, modtime, etc.</a>) Conceptually it is similar to
rsync's <code>--itemize-changes</code>, but not identical -- it should
output an accurate list of what will be on the destination after the
command is finished.</p>
<p>When the <code>--no-traverse</code> flag is set, all logs involving
files that exist only on the destination will be incomplete or
completely missing.</p>
<p>Note that these logger flags have a few limitations, and certain
scenarios are not currently supported:</p>
<ul>
<li><code>--max-duration</code> / <code>CutoffModeHard</code></li>
<li><code>--compare-dest</code> / <code>--copy-dest</code></li>
<li>server-side moves of an entire dir at once</li>
<li>High-level retries, because there would be duplicates (use
<code>--retries 1</code> to disable)</li>
<li>Possibly some unusual error scenarios</li>
</ul>
<p>Note also that each file is logged during execution, as opposed to
after, so it is most useful as a predictor of what SHOULD happen to each
file (which may or may not match what actually DID).</p>

<h1 id="rclone-sync">rclone sync</h1>
<p>Make source and dest identical, modifying destination only.</p>
<h2 id="synopsis-3">Synopsis</h2>
<p>Sync the source to the destination, changing the destination only.
Doesn't transfer files that are identical on source and destination,
testing by size and modification time or MD5SUM. Destination is updated
to match source, including deleting files if necessary (except duplicate
objects, see below). If you don't want to delete files from destination,
use the <a href="https://rclone.org/commands/rclone_copy/">copy</a>
command instead.</p>
<p><strong>Important</strong>: Since this can cause data loss, test
first with the <code>--dry-run</code> or the
<code>--interactive</code>/<code>i</code> flag.</p>
<div class="sourceCode" id="cb54"><pre
class="sourceCode sh"><code class="sourceCode bash"><span id="cb54-1"><a href="#cb54-1" aria-hidden="true" tabindex="-1"></a><span class="ex">rclone</span> sync <span class="at">--interactive</span> SOURCE remote:DESTINATION</span></code></pre></div>
<p>Files in the destination won't be deleted if there were any errors at
any point. Duplicate objects (files with the same name, on those
providers that support it) are not yet handled. Files that are excluded
won't be deleted unless <code>--delete-excluded</code> is used. Symlinks
won't be transferred or deleted from local file systems unless
<code>--links</code> is used.</p>
<p>It is always the contents of the directory that is synced, not the
directory itself. So when source:path is a directory, it's the contents
of source:path that are copied, not the directory name and contents. See
extended explanation in the <a
href="https://rclone.org/commands/rclone_copy/">copy</a> command if
unsure.</p>
<p>If dest:path doesn't exist, it is created and the source:path
contents go there.</p>
<p>It is not possible to sync overlapping remotes. However, you may
exclude the destination from the sync with a filter rule or by putting
an exclude-if-present file inside the destination directory and sync to
a destination that is inside the source directory.</p>
<p>Rclone will sync the modification times of files and directories if
the backend supports it. If metadata syncing is required then use the
<code>--metadata</code> flag.</p>
<p>Note that the modification time and metadata for the root directory
will <strong>not</strong> be synced. See <a
href="https://github.com/rclone/rclone/issues/7652"
class="uri">https://github.com/rclone/rclone/issues/7652</a> for more
info.</p>
<p><strong>Note</strong>: Use the
<code>-P</code>/<code>--progress</code> flag to view real-time transfer
statistics</p>
<p><strong>Note</strong>: Use the <code>rclone dedupe</code> command to
deal with "Duplicate object/directory found in source/destination -
ignoring" errors. See <a

<h1 id="rclone-move">rclone move</h1>
<p>Move files from source to dest.</p>
<h2 id="synopsis-4">Synopsis</h2>
<p>Moves the contents of the source directory to the destination
directory. Rclone will error if the source and destination overlap and
the remote does not support a server-side directory move operation.</p>
<p>To move single files, use the <a
href="https://rclone.org/commands/rclone_moveto/">moveto</a> command
instead.</p>
<p>If no filters are in use and if possible this will server-side move
<code>source:path</code> into <code>dest:path</code>. After this
<code>source:path</code> will no longer exist.</p>
<p>Otherwise for each file in <code>source:path</code> selected by the
filters (if any) this will move it into <code>dest:path</code>. If
possible a server-side move will be used, otherwise it will copy it
(server-side if possible) into <code>dest:path</code> then delete the
original (if no errors on copy) in <code>source:path</code>.</p>
<p>If you want to delete empty source directories after move, use the
<code>--delete-empty-src-dirs</code> flag.</p>
<p>See the <a
href="https://rclone.org/docs/#no-traverse">--no-traverse</a> option for
controlling whether rclone lists the destination directory or not.
Supplying this option when moving a small number of files into a large
destination can speed transfers up greatly.</p>
<p>Rclone will sync the modification times of files and directories if
the backend supports it. If metadata syncing is required then use the
<code>--metadata</code> flag.</p>
<p>Note that the modification time and metadata for the root directory
will <strong>not</strong> be synced. See <a
href="https://github.com/rclone/rclone/issues/7652"
class="uri">https://github.com/rclone/rclone/issues/7652</a> for more
info.</p>
<p><strong>Important</strong>: Since this can cause data loss, test
first with the <code>--dry-run</code> or the
<code>--interactive</code>/<code>-i</code> flag.</p>
<p><strong>Note</strong>: Use the
<code>-P</code>/<code>--progress</code> flag to view real-time transfer
statistics.</p>
<h2 id="logger-flags-2">Logger Flags</h2>
<p>The <code>--differ</code>, <code>--missing-on-dst</code>,
<code>--missing-on-src</code>, <code>--match</code> and
<code>--error</code> flags write paths, one per line, to the file name
(or stdout if it is <code>-</code>) supplied. What they write is
described in the help below. For example <code>--differ</code> will
write all paths which are present on both the source and destination but
different.</p>
<p>The <code>--combined</code> flag will write a file (or stdout) which
contains all file paths with a symbol and then a space and then the path
to tell you what happened to it. These are reminiscent of diff
files.</p>
<ul>
<li><code>= path</code> means path was found in source and destination
and was identical</li>
<li><code>- path</code> means path was missing on the source, so only in
the destination</li>
<li><code>+ path</code> means path was missing on the destination, so
only in the source</li>
<li><code>* path</code> means path was present in source and destination
but different.</li>
<li><code>! path</code> means there was an error reading or hashing the
source or dest.</li>
</ul>
<p>The <code>--dest-after</code> flag writes a list file using the same
format flags as <a
href="https://rclone.org/commands/rclone_lsf/#synopsis"><code>lsf</code></a>
(including <a
href="https://rclone.org/commands/rclone_lsf/#synopsis">customizable
options for hash, modtime, etc.</a>) Conceptually it is similar to
rsync's <code>--itemize-changes</code>, but not identical -- it should
output an accurate list of what will be on the destination after the
command is finished.</p>
<p>When the <code>--no-traverse</code> flag is set, all logs involving
files that exist only on the destination will be incomplete or
completely missing.</p>
<p>Note that these logger flags have a few limitations, and certain
scenarios are not currently supported:</p>
<ul>
<li><code>--max-duration</code> / <code>CutoffModeHard</code></li>
<li><code>--compare-dest</code> / <code>--copy-dest</code></li>
<li>server-side moves of an entire dir at once</li>
<li>High-level retries, because there would be duplicates (use
<code>--retries 1</code> to disable)</li>
<li>Possibly some unusual error scenarios</li>
</ul>
<p>Note also that each file is logged during execution, as opposed to
after, so it is most useful as a predictor of what SHOULD happen to each
file (which may or may not match what actually DID).</p>

<p>Remove the files in path.</p>
<h2 id="synopsis-5">Synopsis</h2>
<p>Remove the files in path. Unlike <a
href="https://rclone.org/commands/rclone_purge/">purge</a> it obeys
include/exclude filters so can be used to selectively delete files.</p>
<p><code>rclone delete</code> only deletes files but leaves the
directory structure alone. If you want to delete a directory and all of
its contents use the <a
href="https://rclone.org/commands/rclone_purge/">purge</a> command.</p>
<p>If you supply the <code>--rmdirs</code> flag, it will remove all
empty directories along with it. You can also use the separate command
<a href="https://rclone.org/commands/rclone_rmdir/">rmdir</a> or <a
href="https://rclone.org/commands/rclone_rmdirs/">rmdirs</a> to delete
empty directories only.</p>
<p>For example, to delete all files bigger than 100 MiB, you may first
want to check what would be deleted (use either):</p>

<h2 id="synopsis-6">Synopsis</h2>
<p>Remove the path and all of its contents. Note that this does not obey
include/exclude filters - everything will be removed. Use the <a
href="https://rclone.org/commands/rclone_delete/">delete</a> command if
you want to selectively delete files. To delete empty directories only,
use command <a

<p>The concurrency of this operation is controlled by the

implement this command directly, in which case <code>--checkers</code>
will be ignored.</p>

<h1 id="rclone-check">rclone check</h1>
<p>Checks the files in the source and destination match.</p>
<h2 id="synopsis-8">Synopsis</h2>
<p>Checks the files in the source and destination match. It compares
sizes and hashes (MD5 or SHA1) and logs a report of files that don't
match. It doesn't alter the source or destination.</p>
<p>For the <a href="https://rclone.org/crypt/">crypt</a> remote there is
a dedicated command, <a
href="https://rclone.org/commands/rclone_cryptcheck/">cryptcheck</a>,
that are able to check the checksums of the encrypted files.</p>
<p>If you supply the <code>--size-only</code> flag, it will only compare
the sizes not the hashes as well. Use this for a quick check.</p>
<p>If you supply the <code>--download</code> flag, it will download the
data from both remotes and check them against each other on the fly.
This can be useful for remotes that don't support hashes or if you
really want to check all the data.</p>
<p>If you supply the <code>--checkfile HASH</code> flag with a valid
hash name, the <code>source:path</code> must point to a text file in the
SUM format.</p>
<p>If you supply the <code>--one-way</code> flag, it will only check
that files in the source match the files in the destination, not the
other way around. This means that extra files in the destination that
are not in the source will not be detected.</p>
<p>The <code>--differ</code>, <code>--missing-on-dst</code>,
<code>--missing-on-src</code>, <code>--match</code> and
<code>--error</code> flags write paths, one per line, to the file name
(or stdout if it is <code>-</code>) supplied. What they write is
described in the help below. For example <code>--differ</code> will
write all paths which are present on both the source and destination but
different.</p>
<p>The <code>--combined</code> flag will write a file (or stdout) which
contains all file paths with a symbol and then a space and then the path
to tell you what happened to it. These are reminiscent of diff
files.</p>
<ul>
<li><code>= path</code> means path was found in source and destination
and was identical</li>
<li><code>- path</code> means path was missing on the source, so only in
the destination</li>
<li><code>+ path</code> means path was missing on the destination, so
only in the source</li>
<li><code>* path</code> means path was present in source and destination
but different.</li>
<li><code>! path</code> means there was an error reading or hashing the
source or dest.</li>
</ul>
<p>The default number of parallel checks is 8. See the <a
href="https://rclone.org/docs/#checkers-int">--checkers</a> option for
more information.</p>

<h2 id="synopsis-11">Synopsis</h2>
<p>Lists the objects in the source path to standard output in a human

default.</p>
<p>E.g.</p>
<pre class="console"><code>$ rclone lsl swift:bucket

<p>Any of the filtering options can be applied to this command.</p>
<p>There are several related list commands</p>
<ul>
<li><code>ls</code> to list size and path of objects only</li>
<li><code>lsl</code> to list modification time, size and path of objects
only</li>
<li><code>lsd</code> to list directories only</li>
<li><code>lsf</code> to list objects and directories in easy to parse
format</li>
<li><code>lsjson</code> to list objects and directories in JSON
format</li>
</ul>
<p><code>ls</code>,<code>lsl</code>,<code>lsd</code> are designed to be
human-readable. <code>lsf</code> is designed to be human and
machine-readable. <code>lsjson</code> is designed to be
machine-readable.</p>
<p>Note that <code>ls</code> and <code>lsl</code> recurse by default -
use <code>--max-depth 1</code> to stop the recursion.</p>
<p>The other list commands
<code>lsd</code>,<code>lsf</code>,<code>lsjson</code> do not recurse by
default - use <code>-R</code> to make them recurse.</p>
<p>Listing a nonexistent directory will produce an error except for
remotes which can't have empty directories (e.g. s3, swift, or gcs - the
bucket-based remotes).</p>

<h1 id="rclone-dedupe">rclone dedupe</h1>
<p>Interactively find duplicate filenames and delete/rename them.</p>
<h2 id="synopsis-17">Synopsis</h2>
<p>By default <code>dedupe</code> interactively finds files with
duplicate names and offers to delete all but one or rename them to be
different. This is known as deduping by name.</p>
<p>Deduping by name is only useful with a small group of backends (e.g.
Google Drive, Opendrive) that can have duplicate file names. It can be
run on wrapping backends (e.g. crypt) if they wrap a backend which
supports duplicate file names.</p>
<p>However if <code>--by-hash</code> is passed in then dedupe will find
files with duplicate hashes instead which will work on any backend which
supports at least one hash. This can be used to find files with
duplicate content. This is known as deduping by hash.</p>
<p>If deduping by name, first rclone will merge directories with the
same name. It will do this iteratively until all the identically named
directories have been merged.</p>
<p>Next, if deduping by name, for every group of duplicate file names /
hashes, it will delete all but one identical file it finds without
confirmation. This means that for most duplicated files the
<code>dedupe</code> command will not be interactive.</p>
<p><code>dedupe</code> considers files to be identical if they have the
same file path and the same hash. If the backend does not support hashes
(e.g. crypt wrapping Google Drive) then they will never be found to be
identical. If you use the <code>--size-only</code> flag then files will
be considered identical if they have the same size (any hash will be
ignored). This can be useful on crypt backends which do not support
hashes.</p>
<p>Next rclone will resolve the remaining duplicates. Exactly which
action is taken depends on the dedupe mode. By default, rclone will
interactively query the user for each one.</p>
<p><strong>Important</strong>: Since this can cause data loss, test
first with the <code>--dry-run</code> or the
<code>--interactive</code>/<code>-i</code> flag.</p>
<p>Here is an example run.</p>
<p>Before - with duplicates</p>

<p>Remote authorization.</p>
<h2 id="synopsis-23">Synopsis</h2>
<p>Remote authorization. Used to authorize a remote or headless rclone
from a machine with a browser. Use as instructed by rclone config. See
also the <a href="/remote_setup">remote setup documentation</a>.</p>
<p>The command requires 1-3 arguments:</p>
<ul>
<li>Name of a backend (e.g. "drive", "s3")</li>
<li>Either a base64 encoded JSON blob obtained from a previous rclone
config session</li>
<li>Or a client_id and client_secret pair obtained from the remote
service</li>
</ul>
<p>Use --auth-no-open-browser to prevent rclone to open auth link in
default browser automatically.</p>
<p>Use --template to generate HTML output via a custom Go template. If a
blank string is provided as an argument to this flag, the default
template is used.</p>

<h1 id="rclone-bisync">rclone bisync</h1>
<p>Perform bidirectional synchronization between two paths.</p>
<h2 id="synopsis-25">Synopsis</h2>
<p>Perform bidirectional synchronization between two paths.</p>
<p><a href="https://rclone.org/bisync/">Bisync</a> provides a
bidirectional cloud sync solution in rclone. It retains the Path1 and
Path2 filesystem listings from the prior run. On each successive run it
will:</p>
<ul>
<li>list files on Path1 and Path2, and check for changes on each side.
Changes include <code>New</code>, <code>Newer</code>,
<code>Older</code>, and <code>Deleted</code> files.</li>
<li>Propagate changes on Path1 to Path2, and vice-versa.</li>
</ul>
<p>Bisync is considered an <strong>advanced command</strong>, so use
with care. Make sure you have read and understood the entire <a
href="https://rclone.org/bisync">manual</a> (especially the <a
href="https://rclone.org/bisync/#limitations">Limitations</a> section)
before using, or data loss can result. Questions can be asked in the <a
href="https://forum.rclone.org/">Rclone Forum</a>.</p>
<p>See <a href="https://rclone.org/bisync/">full bisync description</a>
for details.</p>

      --resilient                            Allow future runs to retry after certain less-serious errors, instead of requiring --resync.
  -1, --resync                               Performs the resync run. Equivalent to --resync-mode path1. Consider using --verbose or --dry-run first.
      --resync-mode string                   During resync, prefer the version that is: path1, path2, newer, older, larger, smaller (default: path1 if --resync, otherwise none for no resync.) (default &quot;none&quot;)
      --slow-hash-sync-only                  Ignore slow checksums for listings and deltas, but still consider them during sync calls.
      --workdir string                       Use custom working dir - useful for testing. (default: {WORKDIR})</code></pre>

<h1 id="rclone-checksum">rclone checksum</h1>
<p>Checks the files in the destination against a SUM file.</p>
<h2 id="synopsis-27">Synopsis</h2>
<p>Checks that hashsums of destination files match the SUM file. It
compares hashes (MD5, SHA1, etc) and logs a report of files which don't
match. It doesn't alter the file system.</p>
<p>The sumfile is treated as the source and the dst:path is treated as
the destination for the purposes of the output.</p>
<p>If you supply the <code>--download</code> flag, it will download the
data from the remote and calculate the content hash on the fly. This can
be useful for remotes that don't support hashes or if you really want to
check all the data.</p>
<p>Note that hash values in the SUM file are treated as case
insensitive.</p>
<p>If you supply the <code>--one-way</code> flag, it will only check
that files in the source match the files in the destination, not the
other way around. This means that extra files in the destination that
are not in the source will not be detected.</p>
<p>The <code>--differ</code>, <code>--missing-on-dst</code>,
<code>--missing-on-src</code>, <code>--match</code> and
<code>--error</code> flags write paths, one per line, to the file name
(or stdout if it is <code>-</code>) supplied. What they write is
described in the help below. For example <code>--differ</code> will
write all paths which are present on both the source and destination but
different.</p>
<p>The <code>--combined</code> flag will write a file (or stdout) which
contains all file paths with a symbol and then a space and then the path
to tell you what happened to it. These are reminiscent of diff
files.</p>
<ul>
<li><code>= path</code> means path was found in source and destination
and was identical</li>
<li><code>- path</code> means path was missing on the source, so only in
the destination</li>
<li><code>+ path</code> means path was missing on the destination, so
only in the source</li>
<li><code>* path</code> means path was present in source and destination
but different.</li>
<li><code>! path</code> means there was an error reading or hashing the
source or dest.</li>
</ul>
<p>The default number of parallel checks is 8. See the <a
href="https://rclone.org/docs/#checkers-int">--checkers</a> option for
more information.</p>

<h1 id="rclone-config-create">rclone config create</h1>
<p>Create a new remote with name, type and options.</p>
<h2 id="synopsis-33">Synopsis</h2>
<p>Create a new remote of <code>name</code> with <code>type</code> and
options. The options should be passed in pairs of <code>key</code>
<code>value</code> or as <code>key=value</code>.</p>
<p>For example, to make a swift remote of name myremote using auto
config you would do:</p>
<div class="sourceCode" id="cb205"><pre
class="sourceCode sh"><code class="sourceCode bash"><span id="cb205-1"><a href="#cb205-1" aria-hidden="true" tabindex="-1"></a><span class="ex">rclone</span> config create myremote swift env_auth true</span>
<span id="cb205-2"><a href="#cb205-2" aria-hidden="true" tabindex="-1"></a><span class="ex">rclone</span> config create myremote swift env_auth=true</span></code></pre></div>
<p>So for example if you wanted to configure a Google Drive remote but
using remote authorization you would do this:</p>
<div class="sourceCode" id="cb206"><pre
class="sourceCode sh"><code class="sourceCode bash"><span id="cb206-1"><a href="#cb206-1" aria-hidden="true" tabindex="-1"></a><span class="ex">rclone</span> config create mydrive drive config_is_local=false</span></code></pre></div>
<p>Note that if the config process would normally ask a question the
default is taken (unless <code>--non-interactive</code> is used). Each
time that happens rclone will print or DEBUG a message saying how to
affect the value taken.</p>
<p>If any of the parameters passed is a password field, then rclone will
automatically obscure them if they aren't already obscured before
putting them in the config file.</p>
<p><strong>NB</strong> If the password parameter is 22 characters or
longer and consists only of base64 characters then rclone can get
confused about whether the password is already obscured or not and put
unobscured passwords into the config file. If you want to be 100%
certain that the passwords get obscured then use the
<code>--obscure</code> flag, or if you are 100% certain you are already
passing obscured passwords then use <code>--no-obscure</code>. You can
also set obscured passwords using the
<code>rclone config password</code> command.</p>
<p>The flag <code>--non-interactive</code> is for use by applications
that wish to configure rclone themselves, rather than using rclone's
text based configuration questions. If this flag is set, and rclone
needs to ask the user a question, a JSON blob will be returned with the
question in it.</p>
<p>This will look something like (some irrelevant detail removed):</p>

<p>Set or change the config file encryption password</p>

<p>This command sets or changes the config file encryption password.</p>
<p>If there was no config password set then it sets a new one, otherwise
it changes the existing config password.</p>
<p>Note that if you are changing an encryption password using
<code>--password-command</code> then this will be called once to decrypt
the config using the old password and then again to read the new
password to re-encrypt the config.</p>
<p>When <code>--password-command</code> is called to change the password
then the environment variable <code>RCLONE_PASSWORD_CHANGE=1</code> will
be set. So if changing passwords programmatically you can use the
environment variable to distinguish which password you must supply.</p>
<p>Alternatively you can remove the password first (with
<code>rclone config encryption remove</code>), then set it again with
this command which may be easier if you don't mind the unencrypted
config file being on the disk briefly.</p>

<h1 id="rclone-config-string">rclone config string</h1>

<p>Print a connection string for a single remote.</p>
<p>The <a href="https://rclone.org/docs/#connection-strings">connection
strings</a> can be used wherever a remote is needed and can be more
convenient than using the config file, especially if using the RC
API.</p>
<p>Backend parameters may be provided to the command also.</p>
<p>Example:</p>
<div class="sourceCode" id="cb241"><pre
class="sourceCode sh"><code class="sourceCode bash"><span id="cb241-1"><a href="#cb241-1" aria-hidden="true" tabindex="-1"></a><span class="ex">$</span> rclone config string s3:rclone <span class="at">--s3-no-check-bucket</span></span>

<p><strong>NB</strong> the strings are not quoted for use in shells (eg
bash, powershell, windows cmd). Most will work if enclosed in "double
quotes", however connection strings that contain double quotes will
require further quoting which is very shell dependent.</p>

<h1 id="rclone-config-update">rclone config update</h1>
<p>Update options in an existing remote.</p>
<h2 id="synopsis-44">Synopsis</h2>
<p>Update an existing remote's options. The options should be passed in
pairs of <code>key</code> <code>value</code> or as
<code>key=value</code>.</p>
<p>For example, to update the env_auth field of a remote of name
myremote you would do:</p>
<div class="sourceCode" id="cb246"><pre
class="sourceCode sh"><code class="sourceCode bash"><span id="cb246-1"><a href="#cb246-1" aria-hidden="true" tabindex="-1"></a><span class="ex">rclone</span> config update myremote env_auth true</span>
<span id="cb246-2"><a href="#cb246-2" aria-hidden="true" tabindex="-1"></a><span class="ex">rclone</span> config update myremote env_auth=true</span></code></pre></div>
<p>If the remote uses OAuth the token will be updated, if you don't
require this add an extra parameter thus:</p>
<div class="sourceCode" id="cb247"><pre
class="sourceCode sh"><code class="sourceCode bash"><span id="cb247-1"><a href="#cb247-1" aria-hidden="true" tabindex="-1"></a><span class="ex">rclone</span> config update myremote env_auth=true config_refresh_token=false</span></code></pre></div>
<p>Note that if the config process would normally ask a question the
default is taken (unless <code>--non-interactive</code> is used). Each
time that happens rclone will print or DEBUG a message saying how to
affect the value taken.</p>
<p>If any of the parameters passed is a password field, then rclone will
automatically obscure them if they aren't already obscured before
putting them in the config file.</p>
<p><strong>NB</strong> If the password parameter is 22 characters or
longer and consists only of base64 characters then rclone can get
confused about whether the password is already obscured or not and put
unobscured passwords into the config file. If you want to be 100%
certain that the passwords get obscured then use the
<code>--obscure</code> flag, or if you are 100% certain you are already
passing obscured passwords then use <code>--no-obscure</code>. You can
also set obscured passwords using the
<code>rclone config password</code> command.</p>
<p>The flag <code>--non-interactive</code> is for use by applications
that wish to configure rclone themselves, rather than using rclone's
text based configuration questions. If this flag is set, and rclone
needs to ask the user a question, a JSON blob will be returned with the
question in it.</p>
<p>This will look something like (some irrelevant detail removed):</p>

<p>The format of <code>Option</code> is the same as returned by

the user and returned to rclone as the <code>--result</code> option
along with the <code>--state</code> parameter.</p>
<p>The keys of <code>Option</code> are used as follows:</p>
<ul>
<li><code>Name</code> - name of variable - show to user</li>
<li><code>Help</code> - help text. Hard wrapped at 80 chars. Any URLs
should be clicky.</li>
<li><code>Default</code> - default value - return this if the user just
wants the default.</li>
<li><code>Examples</code> - the user should be able to choose one of
these</li>
<li><code>Required</code> - the value should be non-empty</li>
<li><code>IsPassword</code> - the value is a password and should be
edited as such</li>
<li><code>Type</code> - type of value, eg <code>bool</code>,
<code>string</code>, <code>int</code> and others</li>
<li><code>Exclusive</code> - if set no free-form entry allowed only the
<code>Examples</code></li>
<li>Irrelevant keys <code>Provider</code>, <code>ShortOpt</code>,
<code>Hide</code>, <code>NoPrefix</code>, <code>Advanced</code></li>

<p>The regex command generally accepts Perl-style regular expressions,
the exact syntax is defined in the <a
href="https://golang.org/pkg/regexp/syntax/">Go regular expression
reference</a>. The replacement string may contain capturing group
variables, referencing capturing groups using the syntax
<code>$name</code> or <code>${name}</code>, where the name can refer to
a named capturing group or it can simply be the index as a number. To
insert a literal $, use $$.</p>
<p>Multiple transformations can be used in sequence, applied in the
order they are specified on the command line.</p>
<p>The <code>--name-transform</code> flag is also available in
<code>sync</code>, <code>copy</code>, and <code>move</code>.</p>
<h2 id="files-vs-directories">Files vs Directories</h2>
<p>By default <code>--name-transform</code> will only apply to file
names. The means only the leaf file name will be transformed. However
some of the transforms would be better applied to the whole path or just
directories. To choose which which part of the file path is affected
some tags can be added to the <code>--name-transform</code>.</p>
<table>
<colgroup>
<col style="width: 50%" />
<col style="width: 50%" />
</colgroup>
<thead>
<tr class="header">
<th>Tag</th>
<th>Effect</th>
</tr>
</thead>
<tbody>
<tr class="odd">
<td><code>file</code></td>
<td>Only transform the leaf name of files (DEFAULT)</td>
</tr>
<tr class="even">
<td><code>dir</code></td>
<td>Only transform name of directories - these may appear anywhere in
the path</td>
</tr>
<tr class="odd">
<td><code>all</code></td>
<td>Transform the entire path for files and directories</td>
</tr>
</tbody>
</table>
<p>This is used by adding the tag into the transform name like this:
<code>--name-transform file,prefix=ABC</code> or
<code>--name-transform dir,prefix=DEF</code>.</p>
<p>For some conversions using all is more likely to be useful, for
example <code>--name-transform all,nfc</code>.</p>
<p>Note that <code>--name-transform</code> may not add path separators
<code>/</code> to the name. This will cause an error.</p>
<h2 id="ordering-and-conflicts">Ordering and Conflicts</h2>
<ul>
<li>Transformations will be applied in the order specified by the user.
<ul>
<li>If the <code>file</code> tag is in use (the default) then only the
leaf name of files will be transformed.</li>
<li>If the <code>dir</code> tag is in use then directories anywhere in
the path will be transformed</li>
<li>If the <code>all</code> tag is in use then directories and files
anywhere in the path will be transformed</li>
<li>Each transformation will be run one path segment at a time.</li>
<li>If a transformation adds a <code>/</code> or ends up with an empty
path segment then that will be an error.</li>
</ul></li>
<li>It is up to the user to put the transformations in a sensible order.
<ul>
<li>Conflicting transformations, such as <code>prefix</code> followed by
<code>trimprefix</code> or <code>nfc</code> followed by
<code>nfd</code>, are possible.</li>
<li>Instead of enforcing mutual exclusivity, transformations are applied
in sequence as specified by the user, allowing for intentional use cases
(e.g., trimming one prefix before adding another).</li>
<li>Users should be aware that certain combinations may lead to
unexpected results and should verify transformations using
<code>--dry-run</code> before execution.</li>
</ul></li>
</ul>
<h2 id="race-conditions-and-non-deterministic-behavior">Race Conditions
and Non-Deterministic Behavior</h2>
<p>Some transformations, such as <code>replace=old:new</code>, may
introduce conflicts where multiple source files map to the same
destination name. This can lead to race conditions when performing
concurrent transfers. It is up to the user to anticipate these.</p>
<ul>
<li>If two files from the source are transformed into the same name at
the destination, the final state may be non-deterministic.</li>
<li>Running rclone check after a sync using such transformations may
erroneously report missing or differing files due to overwritten
results.</li>
</ul>
<p>To minimize risks, users should:</p>
<ul>
<li>Carefully review transformations that may introduce conflicts.</li>
<li>Use <code>--dry-run</code> to inspect changes before executing a
sync (but keep in mind that it won't show the effect of
non-deterministic transformations).</li>
<li>Avoid transformations that cause multiple distinct source files to
map to the same destination name.</li>
<li>Consider disabling concurrency with <code>--transfers=1</code> if
necessary.</li>
<li>Certain transformations (e.g. <code>prefix</code>) will have a
multiplying effect every time they are used. Avoid these when using
<code>bisync</code>.</li>

<h1 id="rclone-copyto">rclone copyto</h1>
<p>Copy files from source to dest, skipping identical files.</p>
<h2 id="synopsis-47">Synopsis</h2>
<p>If source:path is a file or directory then it copies it to a file or
directory named dest:path.</p>
<p>This can be used to upload single files to other than their current
name. If the source is a directory then it acts exactly like the <a
href="https://rclone.org/commands/rclone_copy/">copy</a> command.</p>
<p>So</p>
<pre class="console"><code>rclone copyto src dst</code></pre>
<p>where src and dst are rclone paths, either <code>remote:path</code>
or <code>/path/to/local</code> or
<code>C:\windows\path\if\on\windows</code>.</p>
<p>This will:</p>
<pre class="text"><code>if src is file
    copy it to dst, overwriting an existing file if it exists
if src is directory
    copy it to dst, overwriting existing files if they exist
    see copy command for full details</code></pre>
<p>This doesn't transfer files that are identical on src and dst,
testing by size and modification time or MD5SUM. It doesn't delete files
from the destination.</p>
<p><em>If you are looking to copy just a byte range of a file, please
see <code>rclone cat --offset X --count Y</code>.</em></p>
<p><strong>Note</strong>: Use the
<code>-P</code>/<code>--progress</code> flag to view real-time transfer
statistics.</p>
<h2 id="logger-flags-3">Logger Flags</h2>
<p>The <code>--differ</code>, <code>--missing-on-dst</code>,
<code>--missing-on-src</code>, <code>--match</code> and
<code>--error</code> flags write paths, one per line, to the file name
(or stdout if it is <code>-</code>) supplied. What they write is
described in the help below. For example <code>--differ</code> will
write all paths which are present on both the source and destination but
different.</p>
<p>The <code>--combined</code> flag will write a file (or stdout) which
contains all file paths with a symbol and then a space and then the path
to tell you what happened to it. These are reminiscent of diff
files.</p>
<ul>
<li><code>= path</code> means path was found in source and destination
and was identical</li>
<li><code>- path</code> means path was missing on the source, so only in
the destination</li>
<li><code>+ path</code> means path was missing on the destination, so
only in the source</li>
<li><code>* path</code> means path was present in source and destination
but different.</li>
<li><code>! path</code> means there was an error reading or hashing the
source or dest.</li>
</ul>
<p>The <code>--dest-after</code> flag writes a list file using the same
format flags as <a
href="https://rclone.org/commands/rclone_lsf/#synopsis"><code>lsf</code></a>
(including <a
href="https://rclone.org/commands/rclone_lsf/#synopsis">customizable
options for hash, modtime, etc.</a>) Conceptually it is similar to
rsync's <code>--itemize-changes</code>, but not identical -- it should
output an accurate list of what will be on the destination after the
command is finished.</p>
<p>When the <code>--no-traverse</code> flag is set, all logs involving
files that exist only on the destination will be incomplete or
completely missing.</p>
<p>Note that these logger flags have a few limitations, and certain
scenarios are not currently supported:</p>
<ul>
<li><code>--max-duration</code> / <code>CutoffModeHard</code></li>
<li><code>--compare-dest</code> / <code>--copy-dest</code></li>
<li>server-side moves of an entire dir at once</li>
<li>High-level retries, because there would be duplicates (use
<code>--retries 1</code> to disable)</li>
<li>Possibly some unusual error scenarios</li>
</ul>
<p>Note also that each file is logged during execution, as opposed to
after, so it is most useful as a predictor of what SHOULD happen to each
file (which may or may not match what actually DID).</p>

<h1 id="rclone-copyurl">rclone copyurl</h1>
<p>Copy the contents of the URL supplied content to dest:path.</p>
<h2 id="synopsis-48">Synopsis</h2>
<p>Download a URL's content and copy it to the destination without
saving it in temporary storage.</p>
<p>Setting <code>--auto-filename</code> will attempt to automatically
determine the filename from the URL (after any redirections) and used in
the destination path.</p>
<p>With <code>--header-filename</code> in addition, if a specific
filename is set in HTTP headers, it will be used instead of the name
from the URL. With <code>--print-filename</code> in addition, the
resulting file name will be printed.</p>
<p>Setting <code>--no-clobber</code> will prevent overwriting file on
the destination if there is one with the same name.</p>
<p>Setting <code>--stdout</code> or making the output file name
<code>-</code> will cause the output to be written to standard
output.</p>
<p>Setting <code>--urls</code> allows you to input a CSV file of URLs in
format: URL, FILENAME. If <code>--urls</code> is in use then replace the
URL in the arguments with the file containing the URLs, e.g.:</p>
<div class="sourceCode" id="cb287"><pre
class="sourceCode sh"><code class="sourceCode bash"><span id="cb287-1"><a href="#cb287-1" aria-hidden="true" tabindex="-1"></a><span class="ex">rclone</span> copyurl <span class="at">--urls</span> myurls.csv remote:dir</span></code></pre></div>
<p>Missing filenames will be autogenerated equivalent to using
<code>--auto-filename</code>. Note that <code>--stdout</code> and
<code>--print-filename</code> are incompatible with <code>--urls</code>.
This will do <code>--transfers</code> copies in parallel. Note that if
<code>--auto-filename</code> is desired for all URLs then a file with
only URLs and no filename can be used.</p>
<h2 id="troubleshooting">Troubleshooting</h2>
<p>If you can't get <code>rclone copyurl</code> to work then here are
some things you can try:</p>
<ul>
<li><code>--disable-http2</code> rclone will use HTTP2 if available -
try disabling it</li>
<li><code>--bind 0.0.0.0</code> rclone will use IPv6 if available - try
disabling it</li>
<li><code>--bind ::0</code> to disable IPv4</li>
<li><code>--user agent curl</code> - some sites have whitelists for
curl's user-agent - try that</li>
<li>Make sure the site works with <code>curl</code> directly</li>
</ul>
<pre><code>rclone copyurl https://example.com dest:path [flags]</code></pre>

<h1 id="rclone-cryptcheck">rclone cryptcheck</h1>
<p>Cryptcheck checks the integrity of an encrypted remote.</p>
<h2 id="synopsis-49">Synopsis</h2>
<p>Checks a remote against an <a
href="https://rclone.org/crypt/">encrypted</a> remote. This is the
equivalent of running rclone <a
href="https://rclone.org/commands/rclone_check/">check</a>, but able to
check the checksums of the encrypted remote.</p>
<p>For it to work the underlying remote of the cryptedremote must
support some kind of checksum.</p>
<p>It works by reading the nonce from each file on the cryptedremote:
and using that to encrypt each file on the remote:. It then checks the
checksum of the underlying file on the cryptedremote: against the
checksum of the file it has just encrypted.</p>
<p>Use it like this</p>
<pre class="console"><code>rclone cryptcheck /path/to/files encryptedremote:path</code></pre>
<p>You can use it like this also, but that will involve downloading all
the files in <code>remote:path</code>.</p>
<pre class="console"><code>rclone cryptcheck remote:path encryptedremote:path</code></pre>
<p>After it has run it will log the status of the
<code>encryptedremote:</code>.</p>
<p>If you supply the <code>--one-way</code> flag, it will only check
that files in the source match the files in the destination, not the
other way around. This means that extra files in the destination that
are not in the source will not be detected.</p>
<p>The <code>--differ</code>, <code>--missing-on-dst</code>,
<code>--missing-on-src</code>, <code>--match</code> and
<code>--error</code> flags write paths, one per line, to the file name
(or stdout if it is <code>-</code>) supplied. What they write is
described in the help below. For example <code>--differ</code> will
write all paths which are present on both the source and destination but
different.</p>
<p>The <code>--combined</code> flag will write a file (or stdout) which
contains all file paths with a symbol and then a space and then the path
to tell you what happened to it. These are reminiscent of diff
files.</p>
<ul>
<li><code>= path</code> means path was found in source and destination
and was identical</li>
<li><code>- path</code> means path was missing on the source, so only in
the destination</li>
<li><code>+ path</code> means path was missing on the destination, so
only in the source</li>
<li><code>* path</code> means path was present in source and destination
but different.</li>
<li><code>! path</code> means there was an error reading or hashing the
source or dest.</li>
</ul>
<p>The default number of parallel checks is 8. See the <a
href="https://rclone.org/docs/#checkers-int">--checkers</a> option for
more information.</p>

<h1 id="rclone-gitannex">rclone gitannex</h1>
<p>Speaks with git-annex over stdin/stdout.</p>
<h2 id="synopsis-53">Synopsis</h2>
<p>Rclone's <code>gitannex</code> subcommand enables <a
href="https://git-annex.branchable.com/">git-annex</a> to store and
retrieve content from an rclone remote. It is meant to be run by
git-annex, not directly by users.</p>
<h2 id="installation-on-linux">Installation on Linux</h2>
<ol type="1">
<li><p>Skip this step if your version of git-annex is <a
href="https://git-annex.branchable.com/news/version_10.20240430/">10.20240430</a>
or newer. Otherwise, you must create a symlink somewhere on your PATH
with a particular name. This symlink helps git-annex tell rclone it
wants to run the "gitannex" subcommand.</p>
<p>Create the helper symlink in "$HOME/bin":</p>
<pre class="console"><code>ln -s &quot;$(realpath rclone)&quot; &quot;$HOME/bin/git-annex-remote-rclone-builtin&quot;

Verify the new symlink is on your PATH:

```console
which git-annex-remote-rclone-builtin</code></pre></li>
<li><p>Add a new remote to your git-annex repo. This new remote will
connect git-annex with the <code>rclone gitannex</code> subcommand.</p>
<p>Start by asking git-annex to describe the remote's available
configuration parameters.</p>
<p>If you skipped step 1:</p>
<pre class="console"><code>git annex initremote MyRemote type=rclone --whatelse</code></pre>
<p>If you created a symlink in step 1:</p>
<pre class="console"><code>git annex initremote MyRemote type=external externaltype=rclone-builtin --whatelse</code></pre>
<blockquote>
<p><strong>NOTE</strong>: If you're porting an existing <a
href="https://github.com/git-annex-remote-rclone/git-annex-remote-rclone">git-annex-remote-rclone</a>
remote to use <code>rclone gitannex</code>, you can probably reuse the
configuration parameters verbatim without renaming them. Check parameter
synonyms with <code>--whatelse</code> as shown above.</p>
</blockquote>
<p>The following example creates a new git-annex remote named "MyRemote"
that will use the rclone remote named "SomeRcloneRemote". That rclone
remote must be one configured in your rclone.conf file, which can be
located with <code>rclone config file</code>.</p>
<pre class="console"><code>git annex initremote MyRemote         \
    type=external                     \
    externaltype=rclone-builtin       \
    encryption=none                   \
    rcloneremotename=SomeRcloneRemote \
    rcloneprefix=git-annex-content    \
    rclonelayout=nodir</code></pre></li>
<li><p>Before you trust this command with your precious data, be sure to
<strong>test the remote</strong>. This command is very new and has not
been tested on many rclone backends. Caveat emptor!</p>
<pre class="console"><code>git annex testremote MyRemote</code></pre></li>

<h1 id="rclone-hashsum">rclone hashsum</h1>
<p>Produces a hashsum file for all the objects in the path.</p>
<h2 id="synopsis-54">Synopsis</h2>
<p>Produces a hash file for all the objects in the path using the hash
named. The output is in the same format as the standard md5sum/sha1sum
tool.</p>
<p>By default, the hash is requested from the remote. If the hash is not
supported by the remote, no hash will be returned. With the download
flag, the file will be downloaded from the remote and hashed locally
enabling any hash for any remote.</p>
<p>For the MD5 and SHA1 algorithms there are also dedicated commands, <a
href="https://rclone.org/commands/rclone_md5sum/">md5sum</a> and <a
href="https://rclone.org/commands/rclone_sha1sum/">sha1sum</a>.</p>
<p>This command can also hash data received on standard input (stdin),
by not passing a remote:path, or by passing a hyphen as remote:path when
there is data to read (if not, the hyphen will be treated literally, as
a relative path).</p>
<p>Run without a hash to see the list of all supported hashes, e.g.</p>
<pre class="console"><code>$ rclone hashsum
Supported hashes are:
- md5
- sha1
- whirlpool
- crc32

<h1 id="rclone-lsf">rclone lsf</h1>
<p>List directories and objects in remote:path formatted for
parsing.</p>
<h2 id="synopsis-57">Synopsis</h2>
<p>List the contents of the source path (directories and objects) to
standard output in a form which is easy to parse by scripts. By default
this will just be the names of the objects and directories, one per
line. The directories will have a / suffix.</p>
<p>E.g.</p>
<pre class="console"><code>$ rclone lsf swift:bucket
bevajer5jef
canole
diwogej7
ferejej3gux/
fubuwic</code></pre>
<p>Use the <code>--format</code> option to control what gets listed. By
default this is just the path, but you can use these parameters to
control the output:</p>
<pre class="text"><code>p - path
s - size
t - modification time
h - hash
i - ID of object
o - Original ID of underlying object
m - MimeType of object if known
e - encrypted name
T - tier of storage if known, e.g. &quot;Hot&quot; or &quot;Cool&quot;
M - Metadata of object in JSON blob format, eg {&quot;key&quot;:&quot;value&quot;}</code></pre>
<p>So if you wanted the path, size and modification time, you would use
<code>--format "pst"</code>, or maybe <code>--format "tsp"</code> to put
the path last.</p>
<p>E.g.</p>
<pre class="console"><code>$ rclone lsf  --format &quot;tsp&quot; swift:bucket
2016-06-25 18:55:41;60295;bevajer5jef
2016-06-25 18:55:43;90613;canole
2016-06-25 18:55:43;94467;diwogej7
2018-04-26 08:50:45;0;ferejej3gux/
2016-06-25 18:55:40;37600;fubuwic</code></pre>
<p>If you specify "h" in the format you will get the MD5 hash by
default, use the <code>--hash</code> flag to change which hash you want.
Note that this can be returned as an empty string if it isn't available
on the object (and for directories), "ERROR" if there was an error
reading it from the object and "UNSUPPORTED" if that object does not
support that hash type.</p>
<p>For example, to emulate the md5sum command you can use</p>
<pre class="console"><code>rclone lsf -R --hash MD5 --format hp --separator &quot;  &quot; --files-only .</code></pre>
<p>E.g.</p>
<pre class="console"><code>$ rclone lsf -R --hash MD5 --format hp --separator &quot;  &quot; --files-only swift:bucket

<p>(Though "rclone md5sum ." is an easier way of typing this.)</p>
<p>By default the separator is ";" this can be changed with the
<code>--separator</code> flag. Note that separators aren't escaped in
the path so putting it last is a good strategy.</p>
<p>E.g.</p>
<pre class="console"><code>$ rclone lsf  --separator &quot;,&quot; --format &quot;tshp&quot; swift:bucket

<p>You can output in CSV standard format. This will escape things in "
if they contain,</p>
<p>E.g.</p>
<pre class="console"><code>$ rclone lsf --csv --files-only --format ps remote:path
test.log,22355
test.sh,449
&quot;this file contains a comma, in the file name.txt&quot;,6</code></pre>
<p>Note that the <code>--absolute</code> parameter is useful for making
lists of files to pass to an rclone copy with the
<code>--files-from-raw</code> flag.</p>
<p>For example, to find all the files modified within one day and copy
those only (without traversing the whole directory structure):</p>
<pre class="console"><code>rclone lsf --absolute --files-only --max-age 1d /path/to/local &gt; new_files
rclone copy --files-from-raw new_files /path/to/local remote:path</code></pre>
<p>The default time format is <code>'2006-01-02 15:04:05'</code>. <a
href="https://pkg.go.dev/time#pkg-constants">Other formats</a> can be
specified with the <code>--time-format</code> flag. Examples:</p>
<pre class="console"><code>rclone lsf remote:path --format pt --time-format &#39;Jan 2, 2006 at 3:04pm (MST)&#39;
rclone lsf remote:path --format pt --time-format &#39;2006-01-02 15:04:05.000000000&#39;
rclone lsf remote:path --format pt --time-format &#39;2006-01-02T15:04:05.999999999Z07:00&#39;
rclone lsf remote:path --format pt --time-format RFC3339
rclone lsf remote:path --format pt --time-format DateOnly
rclone lsf remote:path --format pt --time-format max
rclone lsf remote:path --format pt --time-format unix
rclone lsf remote:path --format pt --time-format unixnano</code></pre>
<p><code>--time-format max</code> will automatically truncate
<code>2006-01-02 15:04:05.000000000</code> to the maximum precision
supported by the remote.</p>
<p>Any of the filtering options can be applied to this command.</p>
<p>There are several related list commands</p>
<ul>
<li><code>ls</code> to list size and path of objects only</li>
<li><code>lsl</code> to list modification time, size and path of objects
only</li>
<li><code>lsd</code> to list directories only</li>
<li><code>lsf</code> to list objects and directories in easy to parse
format</li>
<li><code>lsjson</code> to list objects and directories in JSON
format</li>
</ul>
<p><code>ls</code>,<code>lsl</code>,<code>lsd</code> are designed to be
human-readable. <code>lsf</code> is designed to be human and
machine-readable. <code>lsjson</code> is designed to be
machine-readable.</p>
<p>Note that <code>ls</code> and <code>lsl</code> recurse by default -
use <code>--max-depth 1</code> to stop the recursion.</p>
<p>The other list commands
<code>lsd</code>,<code>lsf</code>,<code>lsjson</code> do not recurse by
default - use <code>-R</code> to make them recurse.</p>
<p>Listing a nonexistent directory will produce an error except for
remotes which can't have empty directories (e.g. s3, swift, or gcs - the
bucket-based remotes).</p>

<p>The exact set of properties included depends on the backend:</p>
<ul>
<li>The property IsBucket will only be included for bucket-based
remotes, and only for directories that are buckets. It will always be
omitted when value is not true.</li>
<li>Properties Encrypted and EncryptedPath will only be included for
encrypted remotes, and (as mentioned below) only if the
<code>--encrypted</code> option is set.</li>
</ul>
<p>Different options may also affect which properties are included:</p>
<ul>
<li>If <code>--hash</code> is not specified, the Hashes property will be
omitted. The types of hash can be specified with the
<code>--hash-type</code> parameter (which may be repeated). If
<code>--hash-type</code> is set then it implies
<code>--hash</code>.</li>
<li>If <code>--no-modtime</code> is specified then ModTime will be
blank. This can speed things up on remotes where reading the ModTime
takes an extra request (e.g. s3, swift).</li>
<li>If <code>--no-mimetype</code> is specified then MimeType will be
blank. This can speed things up on remotes where reading the MimeType
takes an extra request (e.g. s3, swift).</li>
<li>If <code>--encrypted</code> is not specified the Encrypted and
EncryptedPath properties will be omitted - even for encrypted
remotes.</li>
<li>If <code>--metadata</code> is set then an additional Metadata
property will be returned. This will have <a
href="https://rclone.org/docs/#metadata">metadata</a> in rclone standard
format as a JSON object.</li>
</ul>
<p>The default is to list directories and files/objects, but this can be
changed with the following options:</p>
<ul>
<li>If <code>--dirs-only</code> is specified then directories will be
returned only, no files/objects.</li>
<li>If <code>--files-only</code> is specified then files will be
returned only, no directories.</li>
</ul>
<p>If <code>--stat</code> is set then the the output is not an array of
items, but instead a single JSON blob will be returned about the item
pointed to. This will return an error if the item isn't found, however
on bucket based backends (like s3, gcs, b2, azureblob etc) if the item
isn't found it will return an empty directory, as it isn't possible to
tell empty directories from missing directories there.</p>
<p>The Path field will only show folders below the remote path being
listed. If "remote:path" contains the file "subfolder/file.txt", the
Path for "file.txt" will be "subfolder/file.txt", not
"remote:path/subfolder/file.txt". When used without
<code>--recursive</code> the Path will always be the same as Name.</p>
<p>The time is in RFC3339 format with up to nanosecond precision. The
number of decimal digits in the seconds will depend on the precision
that the remote can hold the times, so if times are accurate to the
nearest millisecond (e.g. Google Drive) then 3 digits will always be
shown ("2017-05-31T16:15:57.034+01:00") whereas if the times are
accurate to the nearest second (Dropbox, Box, WebDav, etc.) no digits
will be shown ("2017-05-31T16:15:57+01:00").</p>
<p>The whole output can be processed as a JSON blob, or alternatively it
can be processed line by line as each item is written on individual
lines (except with <code>--stat</code>).</p>
<p>Any of the filtering options can be applied to this command.</p>
<p>There are several related list commands</p>
<ul>
<li><code>ls</code> to list size and path of objects only</li>
<li><code>lsl</code> to list modification time, size and path of objects
only</li>
<li><code>lsd</code> to list directories only</li>
<li><code>lsf</code> to list objects and directories in easy to parse
format</li>
<li><code>lsjson</code> to list objects and directories in JSON
format</li>
</ul>
<p><code>ls</code>,<code>lsl</code>,<code>lsd</code> are designed to be
human-readable. <code>lsf</code> is designed to be human and
machine-readable. <code>lsjson</code> is designed to be
machine-readable.</p>
<p>Note that <code>ls</code> and <code>lsl</code> recurse by default -
use <code>--max-depth 1</code> to stop the recursion.</p>
<p>The other list commands
<code>lsd</code>,<code>lsf</code>,<code>lsjson</code> do not recurse by
default - use <code>-R</code> to make them recurse.</p>
<p>Listing a nonexistent directory will produce an error except for
remotes which can't have empty directories (e.g. s3, swift, or gcs - the
bucket-based remotes).</p>

Rclone's cloud storage systems as a file system with FUSE.</p>
<p>First set up your remote using <code>rclone config</code>. Check it
works with <code>rclone ls</code> etc.</p>
<p>On Linux and macOS, you can run mount in either foreground or
background (aka daemon) mode. Mount runs in foreground mode by default.
Use the <code>--daemon</code> flag to force background mode. On Windows
you can run mount in foreground only, the flag is ignored.</p>
<p>In background mode rclone acts as a generic Unix mount program: the
main program starts, spawns background rclone process to setup and
maintain the mount, waits until success or timeout and exits with
appropriate code (killing the child process if it fails).</p>
<p>On Linux/macOS/FreeBSD start the mount like this, where
<code>/path/to/local/mount</code> is an <strong>empty</strong>
<strong>existing</strong> directory:</p>
<pre class="console"><code>rclone mount remote:path/to/files /path/to/local/mount</code></pre>
<p>On Windows you can start a mount in different ways. See <a
href="#mounting-modes-on-windows">below</a> for details. If foreground
mount is used interactively from a console window, rclone will serve the
mount and occupy the console so another window should be used to work
with the mount until rclone is interrupted e.g. by pressing Ctrl-C.</p>
<p>The following examples will mount to an automatically assigned drive,
to specific drive letter <code>X:</code>, to path
<code>C:\path\parent\mount</code> (where parent directory or drive must
exist, and mount must <strong>not</strong> exist, and is not supported
when <a href="#mounting-modes-on-windows">mounting as a network
drive</a>), and the last example will mount as network share
<code>\\cloud\remote</code> and map it to an automatically assigned
drive:</p>
<pre class="console"><code>rclone mount remote:path/to/files *
rclone mount remote:path/to/files X:
rclone mount remote:path/to/files C:\path\parent\mount
rclone mount remote:path/to/files \\cloud\remote</code></pre>
<p>When the program ends while in foreground mode, either via Ctrl+C or
receiving a SIGINT or SIGTERM signal, the mount should be automatically
stopped.</p>
<p>When running in background mode the user will have to stop the mount
manually:</p>
<pre class="console"><code># Linux
fusermount -u /path/to/local/mount
#... or on some systems
fusermount3 -u /path/to/local/mount
# OS X or Linux when using nfsmount
umount /path/to/local/mount</code></pre>
<p>The umount operation can fail, for example when the mountpoint is
busy. When that happens, it is the user's responsibility to stop the
mount manually.</p>
<p>The size of the mounted file system will be set according to
information retrieved from the remote, the same as returned by the <a
href="https://rclone.org/commands/rclone_about/">rclone about</a>
command. Remotes with unlimited storage may report the used size only,
then an additional 1 PiB of free space is assumed. If the remote does
not <a href="https://rclone.org/overview/#optional-features">support</a>
the about feature at all, then 1 PiB is set as both the total and the
free size.</p>
<h2 id="installing-on-windows">Installing on Windows</h2>
<p>To run <code>rclone mount on Windows</code>, you will need to
download and install <a
href="http://www.secfs.net/winfsp/">WinFsp</a>.</p>
<p><a href="https://github.com/winfsp/winfsp">WinFsp</a> is an
open-source Windows File System Proxy which makes it easy to write user
space file systems for Windows. It provides a FUSE emulation layer which
rclone uses combination with <a
href="https://github.com/winfsp/cgofuse">cgofuse</a>. Both of these
packages are by Bill Zissimopoulos who was very helpful during the
implementation of rclone mount for Windows.</p>
<h3 id="mounting-modes-on-windows">Mounting modes on windows</h3>
<p>Unlike other operating systems, Microsoft Windows provides a
different filesystem type for network and fixed drives. It optimises
access on the assumption fixed disk drives are fast and reliable, while
network drives have relatively high latency and less reliability. Some
settings can also be differentiated between the two types, for example
that Windows Explorer should just display icons and not create preview
thumbnails for image and video files on network drives.</p>
<p>In most cases, rclone will mount the remote as a normal, fixed disk
drive by default. However, you can also choose to mount it as a remote
network drive, often described as a network share. If you mount an
rclone remote using the default, fixed drive mode and experience
unexpected program errors, freezes or other issues, consider mounting as
a network drive instead.</p>
<p>When mounting as a fixed disk drive you can either mount to an unused
drive letter, or to a path representing a <strong>nonexistent</strong>
subdirectory of an <strong>existing</strong> parent directory or drive.
Using the special value <code>*</code> will tell rclone to automatically
assign the next available drive letter, starting with Z: and moving
backward. Examples:</p>
<pre class="console"><code>rclone mount remote:path/to/files *
rclone mount remote:path/to/files X:
rclone mount remote:path/to/files C:\path\parent\mount
rclone mount remote:path/to/files X:</code></pre>
<p>Option <code>--volname</code> can be used to set a custom volume name
for the mounted file system. The default is to use the remote name and
path.</p>
<p>To mount as network drive, you can add option
<code>--network-mode</code> to your mount command. Mounting to a
directory path is not supported in this mode, it is a limitation Windows
imposes on junctions, so the remote must always be mounted to a drive
letter.</p>
<pre class="console"><code>rclone mount remote:path/to/files X: --network-mode</code></pre>
<p>A volume name specified with <code>--volname</code> will be used to
create the network share path. A complete UNC path, such as
<code>\\cloud\remote</code>, optionally with path
<code>\\cloud\remote\madeup\path</code>, will be used as is. Any other
string will be used as the share part, after a default prefix
<code>\\server\</code>. If no volume name is specified then
<code>\\server\share</code> will be used. You must make sure the volume
name is unique when you are mounting more than one drive, or else the
mount command will fail. The share name will treated as the volume label
for the mapped drive, shown in Windows Explorer etc, while the complete
<code>\\server\share</code> will be reported as the remote UNC path by
<code>net use</code> etc, just like a normal network drive mapping.</p>
<p>If you specify a full network share UNC path with
<code>--volname</code>, this will implicitly set the
<code>--network-mode</code> option, so the following two examples have
same result:</p>
<pre class="console"><code>rclone mount remote:path/to/files X: --network-mode
rclone mount remote:path/to/files X: --volname \\server\share</code></pre>
<p>You may also specify the network share UNC path as the mountpoint
itself. Then rclone will automatically assign a drive letter, same as
with <code>*</code> and use that as mountpoint, and instead use the UNC
path specified as the volume name, as if it were specified with the
<code>--volname</code> option. This will also implicitly set the
<code>--network-mode</code> option. This means the following two
examples have same result:</p>
<pre class="console"><code>rclone mount remote:path/to/files \\cloud\remote
rclone mount remote:path/to/files * --volname \\cloud\remote</code></pre>
<p>There is yet another way to enable network mode, and to set the share
path, and that is to pass the "native" libfuse/WinFsp option directly:
<code>--fuse-flag --VolumePrefix=\server\share</code>. Note that the
path must be with just a single backslash prefix in this case.</p>
<p><em>Note:</em> In previous versions of rclone this was the only
supported method.</p>

<h3 id="windows-filesystem-permissions">Windows filesystem
permissions</h3>
<p>The FUSE emulation layer on Windows must convert between the
POSIX-based permission model used in FUSE, and the permission model used
in Windows, based on access-control lists (ACL).</p>
<p>The mounted filesystem will normally get three entries in its
access-control list (ACL), representing permissions for the POSIX
permission scopes: Owner, group and others. By default, the owner and
group will be taken from the current user, and the built-in group
"Everyone" will be used to represent others. The user/group can be
customized with FUSE options "UserName" and "GroupName", e.g.
<code>-o UserName=user123 -o GroupName="Authenticated Users"</code>. The
permissions on each entry will be set according to <a
href="#options">options</a> <code>--dir-perms</code> and
<code>--file-perms</code>, which takes a value in traditional Unix <a
href="https://en.wikipedia.org/wiki/File-system_permissions#Numeric_notation">numeric
notation</a>.</p>
<p>The default permissions corresponds to
<code>--file-perms 0666 --dir-perms 0777</code>, i.e. read and write
permissions to everyone. This means you will not be able to start any
programs from the mount. To be able to do that you must add execute
permissions, e.g. <code>--file-perms 0777 --dir-perms 0777</code> to add
it to everyone. If the program needs to write files, chances are you
will have to enable <a href="#vfs-file-caching">VFS File Caching</a> as
well (see also <a href="#limitations">limitations</a>). Note that the
default write permission have some restrictions for accounts other than
the owner, specifically it lacks the "write extended attributes", as
explained next.</p>
<p>The mapping of permissions is not always trivial, and the result you
see in Windows Explorer may not be exactly like you expected. For
example, when setting a value that includes write access for the group
or others scope, this will be mapped to individual permissions "write
attributes", "write data" and "append data", but not "write extended
attributes". Windows will then show this as basic permission "Special"
instead of "Write", because "Write" also covers the "write extended
attributes" permission. When setting digit 0 for group or others, to
indicate no permissions, they will still get individual permissions
"read attributes", "read extended attributes" and "read permissions".
This is done for compatibility reasons, e.g. to allow users without
additional permissions to be able to read basic metadata about files
like in Unix.</p>
<p>WinFsp 2021 (version 1.9) introduced a new FUSE option
"FileSecurity", that allows the complete specification of file security
descriptors using <a
href="https://docs.microsoft.com/en-us/windows/win32/secauthz/security-descriptor-string-format">SDDL</a>.
With this you get detailed control of the resulting permissions,
compared to use of the POSIX permissions described above, and no
additional permissions will be added automatically for compatibility
with Unix. Some example use cases will following.</p>
<p>If you set POSIX permissions for only allowing access to the owner,
using <code>--file-perms 0600 --dir-perms 0700</code>, the user group
and the built-in "Everyone" group will still be given some special
permissions, as described above. Some programs may then (incorrectly)
interpret this as the file being accessible by everyone, for example an
SSH client may warn about "unprotected private key file". You can work
around this by specifying
<code>-o FileSecurity="D:P(A;;FA;;;OW)"</code>, which sets file all
access (FA) to the owner (OW), and nothing else.</p>
<p>When setting write permissions then, except for the owner, this does
not include the "write extended attributes" permission, as mentioned
above. This may prevent applications from writing to files, giving
permission denied error instead. To set working write permissions for
the built-in "Everyone" group, similar to what it gets by default but
with the addition of the "write extended attributes", you can specify
<code>-o FileSecurity="D:P(A;;FRFW;;;WD)"</code>, which sets file read
(FR) and file write (FW) to everyone (WD). If file execute (FX) is also
needed, then change to
<code>-o FileSecurity="D:P(A;;FRFWFX;;;WD)"</code>, or set file all
access (FA) to get full access permissions, including delete, with
<code>-o FileSecurity="D:P(A;;FA;;;WD)"</code>.</p>
<h3 id="windows-caveats">Windows caveats</h3>
<p>Drives created as Administrator are not visible to other accounts,
not even an account that was elevated to Administrator with the User
Account Control (UAC) feature. A result of this is that if you mount to
a drive letter from a Command Prompt run as Administrator, and then try
to access the same drive from Windows Explorer (which does not run as
Administrator), you will not be able to see the mounted drive.</p>
<p>If you don't need to access the drive from applications running with
administrative privileges, the easiest way around this is to always
create the mount from a non-elevated command prompt.</p>
<p>To make mapped drives available to the user account that created them
regardless if elevated or not, there is a special Windows setting called
<a
href="https://docs.microsoft.com/en-us/troubleshoot/windows-client/networking/mapped-drives-not-available-from-elevated-command#detail-to-configure-the-enablelinkedconnections-registry-entry">linked
connections</a> that can be enabled.</p>
<p>It is also possible to make a drive mount available to everyone on
the system, by running the process creating it as the built-in SYSTEM
account. There are several ways to do this: One is to use the
command-line utility <a
href="https://docs.microsoft.com/en-us/sysinternals/downloads/psexec">PsExec</a>,
from Microsoft's Sysinternals suite, which has option <code>-s</code> to
start processes as the SYSTEM account. Another alternative is to run the
mount command from a Windows Scheduled Task, or a Windows Service,
configured to run as the SYSTEM account. A third alternative is to use
the <a
href="https://github.com/winfsp/winfsp/wiki/WinFsp-Service-Architecture">WinFsp.Launcher
infrastructure</a>). Read more in the <a
href="https://rclone.org/install/">install documentation</a>. Note that
when running rclone as another user, it will not use the configuration
file from your profile unless you tell it to with the <a
href="https://rclone.org/docs/#config-string"><code>--config</code></a>
option. Note also that it is now the SYSTEM account that will have the
owner permissions, and other accounts will have permissions according to
the group or others scopes. As mentioned above, these will then not get
the "write extended attributes" permission, and this may prevent writing
to files. You can work around this with the FileSecurity option, see
example above.</p>
<p>Note that mapping to a directory path, instead of a drive letter,
does not suffer from the same limitations.</p>
<h2 id="mounting-on-macos">Mounting on macOS</h2>
<p>Mounting on macOS can be done either via <a
href="https://rclone.org/commands/rclone_serve_nfs/">built-in NFS
server</a>, <a href="https://osxfuse.github.io/">macFUSE</a> (also known
as osxfuse) or <a href="https://www.fuse-t.org/">FUSE-T</a>.macFUSE is a
traditional FUSE driver utilizing a macOS kernel extension (kext).
FUSE-T is an alternative FUSE system which "mounts" via an NFSv4 local
server.</p>
<h3 id="unicode-normalization">Unicode Normalization</h3>
<p>It is highly recommended to keep the default of
<code>--no-unicode-normalization=false</code> for all <code>mount</code>
and <code>serve</code> commands on macOS. For details, see <a
href="https://rclone.org/commands/rclone_mount/#vfs-case-sensitivity">vfs-case-sensitivity</a>.</p>
<h3 id="nfs-mount">NFS mount</h3>
<p>This method spins up an NFS server using <a
href="https://rclone.org/commands/rclone_serve_nfs/">serve nfs</a>
command and mounts it to the specified mountpoint. If you run this in
background mode using |--daemon|, you will need to send SIGTERM signal
to the rclone process using |kill| command to stop the mount.</p>
<p>Note that <code>--nfs-cache-handle-limit</code> controls the maximum
number of cached file handles stored by the <code>nfsmount</code>
caching handler. This should not be set too low or you may experience
errors when trying to access files. The default is 1000000, but consider
lowering this limit if the server's system resource usage causes
problems.</p>
<h3 id="macfuse-notes">macFUSE Notes</h3>
<p>If installing macFUSE using <a
href="https://github.com/osxfuse/osxfuse/releases">dmg packages</a> from
the website, rclone will locate the macFUSE libraries without any
further intervention. If however, macFUSE is installed using the <a
href="https://www.macports.org/">macports</a> package manager, the
following addition steps are required.</p>
<pre class="console"><code>sudo mkdir /usr/local/lib
cd /usr/local/lib
sudo ln -s /opt/local/lib/libfuse.2.dylib</code></pre>
<h3 id="fuse-t-limitations-caveats-and-notes">FUSE-T Limitations,
Caveats, and Notes</h3>
<p>There are some limitations, caveats, and notes about how it works.
These are current as of FUSE-T version 1.0.14.</p>
<h4 id="modtime-update-on-read">ModTime update on read</h4>
<p>As per the <a
href="https://github.com/macos-fuse-t/fuse-t/wiki#caveats">FUSE-T
wiki</a>:</p>
<blockquote>
<p>File access and modification times cannot be set separately as it
seems to be an issue with the NFS client which always modifies both. Can
be reproduced with 'touch -m' and 'touch -a' commands</p>
</blockquote>
<p>This means that viewing files with various tools, notably macOS
Finder, will cause rlcone to update the modification time of the file.
This may make rclone upload a full new copy of the file.</p>
<h4 id="read-only-mounts">Read Only mounts</h4>
<p>When mounting with <code>--read-only</code>, attempts to write to
files will fail <em>silently</em> as opposed to with a clear warning as
in macFUSE.</p>
<h1 id="mounting-on-linux">Mounting on Linux</h1>
<p>On newer versions of Ubuntu, you may encounter the following error
when running <code>rclone mount</code>:</p>
<blockquote>
<p>NOTICE: mount helper error: fusermount3: mount failed: Permission
denied CRITICAL: Fatal error: failed to mount FUSE fs: fusermount: exit
status 1 This may be due to newer <a
href="https://wiki.ubuntu.com/AppArmor">Apparmor</a> restrictions, which
can be disabled with <code>sudo aa-disable /usr/bin/fusermount3</code>
(you may need to <code>sudo apt install apparmor-utils</code>
beforehand).</p>
</blockquote>
<h2 id="limitations">Limitations</h2>
<p>Without the use of <code>--vfs-cache-mode</code> this can only write
files sequentially, it can only seek when reading. This means that many
applications won't work with their files on an rclone mount without
<code>--vfs-cache-mode writes</code> or
<code>--vfs-cache-mode full</code>. See the <a
href="#vfs-file-caching">VFS File Caching</a> section for more info.
When using NFS mount on macOS, if you don't specify |--vfs-cache-mode|
the mount point will be read-only.</p>
<p>Bucket-based remotes - Azure Blob, Swift, S3, Google Cloud Storage
and B2 - can't store empty directories. Of these, only Azure Blob,
Google Cloud Storage and S3 can preserve them when you add
<code>--xxx-directory_markers</code>; otherwise, empty directories will
vanish once they drop out of the directory cache.</p>
<p>When <code>rclone mount</code> is invoked on Unix with
<code>--daemon</code> flag, the main rclone program will wait for the
background mount to become ready or until the timeout specified by the
<code>--daemon-wait</code> flag. On Linux it can check mount status
using ProcFS so the flag in fact sets <strong>maximum</strong> time to
wait, while the real wait can be less. On macOS / BSD the time to wait
is constant and the check is performed only at the end. We advise you to
set wait time on macOS reasonably.</p>
<p>Only supported on Linux, FreeBSD, OS X and Windows at the moment.</p>
<h2 id="rclone-mount-vs-rclone-synccopy">rclone mount vs rclone
sync/copy</h2>
<p>File systems expect things to be 100% reliable, whereas cloud storage
systems are a long way from 100% reliable. The rclone sync/copy commands
cope with this with lots of retries. However rclone mount can't use
retries in the same way without making local copies of the uploads. Look
at the <a href="#vfs-file-caching">VFS File Caching</a> for solutions to
make mount more reliable.</p>
<h2 id="attribute-caching">Attribute caching</h2>
<p>You can use the flag <code>--attr-timeout</code> to set the time the
kernel caches the attributes (size, modification time, etc.) for
directory entries.</p>
<p>The default is <code>1s</code> which caches files just long enough to
avoid too many callbacks to rclone from the kernel.</p>
<p>In theory 0s should be the correct value for filesystems which can
change outside the control of the kernel. However this causes quite a
few problems such as <a
href="https://github.com/rclone/rclone/issues/2157">rclone using too
much memory</a>, <a
href="https://forum.rclone.org/t/rclone-1-39-vs-1-40-mount-issue/5112">rclone
not serving files to samba</a> and <a
href="https://github.com/rclone/rclone/issues/2095#issuecomment-371141147">excessive
time listing directories</a>.</p>
<p>The kernel can cache the info about a file for the time given by
<code>--attr-timeout</code>. You may see corruption if the remote file
changes length during this window. It will show up as either a truncated
file or a file with garbage on the end. With
<code>--attr-timeout 1s</code> this is very unlikely but not impossible.
The higher you set <code>--attr-timeout</code> the more likely it is.
The default setting of "1s" is the lowest setting which mitigates the
problems above.</p>
<p>If you set it higher (<code>10s</code> or <code>1m</code> say) then
the kernel will call back to rclone less often making it more efficient,
however there is more chance of the corruption issue above.</p>
<p>If files don't change on the remote outside of the control of rclone
then there is no chance of corruption.</p>
<p>This is the same as setting the attr_timeout option in
mount.fuse.</p>
<h2 id="filters">Filters</h2>
<p>Note that all the rclone filters can be used to select a subset of
the files to be visible in the mount.</p>
<h2 id="systemd">systemd</h2>
<p>When running rclone mount as a systemd service, it is possible to use
Type=notify. In this case the service will enter the started state after
the mountpoint has been successfully set up. Units having the rclone
mount service specified as a requirement will see all files and folders
immediately in this mode.</p>
<p>Note that systemd runs mount units without any environment variables
including <code>PATH</code> or <code>HOME</code>. This means that tilde
(<code>~</code>) expansion will not work and you should provide
<code>--config</code> and <code>--cache-dir</code> explicitly as
absolute paths via rclone arguments. Since mounting requires the
<code>fusermount</code> or <code>fusermount3</code> program, rclone will
use the fallback PATH of <code>/bin:/usr/bin</code> in this scenario.
Please ensure that <code>fusermount</code>/<code>fusermount3</code> is
present on this PATH.</p>
<h2 id="rclone-as-unix-mount-helper">Rclone as Unix mount helper</h2>
<p>The core Unix program <code>/bin/mount</code> normally takes the
<code>-t FSTYPE</code> argument then runs the
<code>/sbin/mount.FSTYPE</code> helper program passing it mount options
as <code>-o key=val,...</code> or <code>--opt=...</code>. Automount
(classic or systemd) behaves in a similar way.</p>
<p>rclone by default expects GNU-style flags <code>--key val</code>. To
run it as a mount helper you should symlink rclone binary to
<code>/sbin/mount.rclone</code> and optionally
<code>/usr/bin/rclonefs</code>, e.g.
<code>ln -s /usr/bin/rclone /sbin/mount.rclone</code>. rclone will
detect it and translate command-line arguments appropriately.</p>
<p>Now you can run classic mounts like this:</p>
<pre class="console"><code>mount sftp1:subdir /mnt/data -t rclone -o vfs_cache_mode=writes,sftp_key_file=/path/to/pem</code></pre>
<p>or create systemd mount units:</p>

<p>or add in <code>/etc/fstab</code> a line like</p>
<pre class="console"><code>sftp1:subdir /mnt/data rclone rw,noauto,nofail,_netdev,x-systemd.automount,args2env,vfs_cache_mode=writes,config=/etc/rclone.conf,cache_dir=/var/cache/rclone 0 0</code></pre>
<p>or use classic Automountd. Remember to provide explicit
<code>config=...,cache-dir=...</code> as a workaround for mount units
being run without <code>HOME</code>.</p>
<p>Rclone in the mount helper mode will split <code>-o</code>
argument(s) by comma, replace <code>_</code> by <code>-</code> and
prepend <code>--</code> to get the command-line flags. Options
containing commas or spaces can be wrapped in single or double quotes.
Any inner quotes inside outer quotes of the same type should be
doubled.</p>
<p>Mount option syntax includes a few extra options treated
specially:</p>
<ul>
<li><code>env.NAME=VALUE</code> will set an environment variable for the
mount process. This helps with Automountd and Systemd.mount which don't
allow setting custom environment for mount helpers. Typically you will
use <code>env.HTTPS_PROXY=proxy.host:3128</code> or
<code>env.HOME=/root</code></li>
<li><code>command=cmount</code> can be used to run <code>cmount</code>
or any other rclone command rather than the default
<code>mount</code>.</li>
<li><code>args2env</code> will pass mount options to the mount helper
running in background via environment variables instead of command line
arguments. This allows to hide secrets from such commands as
<code>ps</code> or <code>pgrep</code>.</li>
<li><code>vv...</code> will be transformed into appropriate
<code>--verbose=N</code></li>
<li>standard mount options like <code>x-systemd.automount</code>,
<code>_netdev</code>, <code>nosuid</code> and alike are intended only
for Automountd and ignored by rclone.</li>
</ul>
<h2 id="vfs---virtual-file-system">VFS - Virtual File System</h2>
<p>This command uses the VFS layer. This adapts the cloud storage
objects that rclone uses into something which looks much more like a
disk filing system.</p>
<p>Cloud storage objects have lots of properties which aren't like disk
files - you can't extend them or write to the middle of them, so the VFS
layer has to deal with that. Because there is no one right way of doing
this there are various options explained below.</p>
<p>The VFS layer also implements a directory cache - this caches info
about files and directories (but not the data) in memory.</p>
<h2 id="vfs-directory-cache">VFS Directory Cache</h2>
<p>Using the <code>--dir-cache-time</code> flag, you can control how
long a directory should be considered up to date and not refreshed from
the backend. Changes made through the VFS will appear immediately or
invalidate the cache.</p>
<pre class="text"><code>    --dir-cache-time duration   Time to cache directory entries for (default 5m0s)
    --poll-interval duration    Time to wait between polling for changes. Must be smaller than dir-cache-time. Only on supported remotes. Set to 0 to disable (default 1m0s)</code></pre>
<p>However, changes made directly on the cloud storage by the web
interface or a different copy of rclone will only be picked up once the
directory cache expires if the backend configured does not support
polling for changes. If the backend supports polling, changes will be
picked up within the polling interval.</p>
<p>You can send a <code>SIGHUP</code> signal to rclone for it to flush
all directory caches, regardless of how old they are. Assuming only one
rclone instance is running, you can reset the cache like this:</p>
<pre class="console"><code>kill -SIGHUP $(pidof rclone)</code></pre>
<p>If you configure rclone with a <a href="/rc">remote control</a> then
you can use rclone rc to flush the whole directory cache:</p>
<pre class="console"><code>rclone rc vfs/forget</code></pre>
<p>Or individual files or directories:</p>
<pre class="console"><code>rclone rc vfs/forget file=path/to/file dir=path/to/dir</code></pre>
<h2 id="vfs-file-buffering">VFS File Buffering</h2>
<p>The <code>--buffer-size</code> flag determines the amount of memory,
that will be used to buffer data in advance.</p>
<p>Each open file will try to keep the specified amount of data in
memory at all times. The buffered data is bound to one open file and
won't be shared.</p>
<p>This flag is a upper limit for the used memory per open file. The
buffer will only use memory for data that is downloaded but not not yet
read. If the buffer is empty, only a small amount of memory will be
used.</p>
<p>The maximum memory used by rclone for buffering can be up to
<code>--buffer-size * open files</code>.</p>
<h2 id="vfs-file-caching">VFS File Caching</h2>
<p>These flags control the VFS file caching options. File caching is
necessary to make the VFS layer appear compatible with a normal file
system. It can be disabled at the cost of some compatibility.</p>
<p>For example you'll need to enable VFS caching if you want to read and
write simultaneously to a file. See below for more details.</p>
<p>Note that the VFS cache is separate from the cache backend and you
may find that you need one or the other or both.</p>
<pre class="text"><code>    --cache-dir string                     Directory rclone will use for caching.
    --vfs-cache-mode CacheMode             Cache mode off|minimal|writes|full (default off)
    --vfs-cache-max-age duration           Max time since last access of objects in the cache (default 1h0m0s)
    --vfs-cache-max-size SizeSuffix        Max total size of objects in the cache (default off)
    --vfs-cache-min-free-space SizeSuffix  Target minimum free space on the disk containing the cache (default off)
    --vfs-cache-poll-interval duration     Interval to poll the cache for stale objects (default 1m0s)
    --vfs-write-back duration              Time to writeback files after last use when using cache (default 5s)</code></pre>
<p>If run with <code>-vv</code> rclone will print the location of the
file cache. The files are stored in the user cache file area which is OS
dependent but can be controlled with <code>--cache-dir</code> or setting
the appropriate environment variable.</p>
<p>The cache has 4 different modes selected by
<code>--vfs-cache-mode</code>. The higher the cache mode the more
compatible rclone becomes at the cost of using disk space.</p>
<p>Note that files are written back to the remote only when they are
closed and if they haven't been accessed for
<code>--vfs-write-back</code> seconds. If rclone is quit or dies with
files that haven't been uploaded, these will be uploaded next time
rclone is run with the same flags.</p>
<p>If using <code>--vfs-cache-max-size</code> or
<code>--vfs-cache-min-free-space</code> note that the cache may exceed
these quotas for two reasons. Firstly because it is only checked every
<code>--vfs-cache-poll-interval</code>. Secondly because open files
cannot be evicted from the cache. When <code>--vfs-cache-max-size</code>
or <code>--vfs-cache-min-free-space</code> is exceeded, rclone will
attempt to evict the least accessed files from the cache first. rclone
will start with files that haven't been accessed for the longest. This
cache flushing strategy is efficient and more relevant files are likely
to remain cached.</p>
<p>The <code>--vfs-cache-max-age</code> will evict files from the cache
after the set time since last access has passed. The default value of 1
hour will start evicting files from cache that haven't been accessed for
1 hour. When a cached file is accessed the 1 hour timer is reset to 0
and will wait for 1 more hour before evicting. Specify the time with
standard notation, s, m, h, d, w .</p>
<p>You <strong>should not</strong> run two copies of rclone using the
same VFS cache with the same or overlapping remotes if using
<code>--vfs-cache-mode &gt; off</code>. This can potentially cause data
corruption if you do. You can work around this by giving each rclone its
own cache hierarchy with <code>--cache-dir</code>. You don't need to
worry about this if the remotes in use don't overlap.</p>
<h3 id="vfs-cache-mode-off">--vfs-cache-mode off</h3>
<p>In this mode (the default) the cache will read directly from the
remote and write directly to the remote without caching anything on
disk.</p>
<p>This will mean some operations are not possible</p>
<ul>
<li>Files can't be opened for both read AND write</li>
<li>Files opened for write can't be seeked</li>
<li>Existing files opened for write must have O_TRUNC set</li>
<li>Files open for read with O_TRUNC will be opened write only</li>
<li>Files open for write only will behave as if O_TRUNC was
supplied</li>
<li>Open modes O_APPEND, O_TRUNC are ignored</li>
<li>If an upload fails it can't be retried</li>
</ul>
<h3 id="vfs-cache-mode-minimal">--vfs-cache-mode minimal</h3>
<p>This is very similar to "off" except that files opened for read AND
write will be buffered to disk. This means that files opened for write
will be a lot more compatible, but uses the minimal disk space.</p>
<p>These operations are not possible</p>
<ul>
<li>Files opened for write only can't be seeked</li>
<li>Existing files opened for write must have O_TRUNC set</li>
<li>Files opened for write only will ignore O_APPEND, O_TRUNC</li>
<li>If an upload fails it can't be retried</li>
</ul>
<h3 id="vfs-cache-mode-writes">--vfs-cache-mode writes</h3>
<p>In this mode files opened for read only are still read directly from
the remote, write only and read/write files are buffered to disk
first.</p>
<p>This mode should support all normal file system operations.</p>
<p>If an upload fails it will be retried at exponentially increasing
intervals up to 1 minute.</p>
<h3 id="vfs-cache-mode-full">--vfs-cache-mode full</h3>
<p>In this mode all reads and writes are buffered to and from disk. When
data is read from the remote this is buffered to disk as well.</p>
<p>In this mode the files in the cache will be sparse files and rclone
will keep track of which bits of the files it has downloaded.</p>
<p>So if an application only reads the starts of each file, then rclone
will only buffer the start of the file. These files will appear to be
their full size in the cache, but they will be sparse files with only
the data that has been downloaded present in them.</p>
<p>This mode should support all normal file system operations and is
otherwise identical to <code>--vfs-cache-mode</code> writes.</p>
<p>When reading a file rclone will read <code>--buffer-size</code> plus
<code>--vfs-read-ahead</code> bytes ahead. The
<code>--buffer-size</code> is buffered in memory whereas the
<code>--vfs-read-ahead</code> is buffered on disk.</p>
<p>When using this mode it is recommended that
<code>--buffer-size</code> is not set too large and
<code>--vfs-read-ahead</code> is set large if required.</p>
<p><strong>IMPORTANT</strong> not all file systems support sparse files.
In particular FAT/exFAT do not. Rclone will perform very badly if the
cache directory is on a filesystem which doesn't support sparse files
and it will log an ERROR message if one is detected.</p>
<h3 id="fingerprinting">Fingerprinting</h3>
<p>Various parts of the VFS use fingerprinting to see if a local file
copy has changed relative to a remote file. Fingerprints are made
from:</p>
<ul>
<li>size</li>
<li>modification time</li>
<li>hash</li>
</ul>
<p>where available on an object.</p>
<p>On some backends some of these attributes are slow to read (they take
an extra API call per object, or extra work per object).</p>
<p>For example <code>hash</code> is slow with the <code>local</code> and
<code>sftp</code> backends as they have to read the entire file and hash
it, and <code>modtime</code> is slow with the <code>s3</code>,
<code>swift</code>, <code>ftp</code> and <code>qinqstor</code> backends
because they need to do an extra API call to fetch it.</p>
<p>If you use the <code>--vfs-fast-fingerprint</code> flag then rclone
will not include the slow operations in the fingerprint. This makes the
fingerprinting less accurate but much faster and will improve the
opening time of cached files.</p>
<p>If you are running a vfs cache over <code>local</code>,
<code>s3</code> or <code>swift</code> backends then using this flag is
recommended.</p>
<p>Note that if you change the value of this flag, the fingerprints of
the files in the cache may be invalidated and the files will need to be
downloaded again.</p>
<h2 id="vfs-chunked-reading">VFS Chunked Reading</h2>
<p>When rclone reads files from a remote it reads them in chunks. This
means that rather than requesting the whole file rclone reads the chunk
specified. This can reduce the used download quota for some remotes by
requesting only chunks from the remote that are actually read, at the
cost of an increased number of requests.</p>
<p>These flags control the chunking:</p>
<pre class="text"><code>    --vfs-read-chunk-size SizeSuffix        Read the source objects in chunks (default 128M)
    --vfs-read-chunk-size-limit SizeSuffix  Max chunk doubling size (default off)
    --vfs-read-chunk-streams int            The number of parallel streams to read at once</code></pre>
<p>The chunking behaves differently depending on the
<code>--vfs-read-chunk-streams</code> parameter.</p>
<h3 id="vfs-read-chunk-streams-0"><code>--vfs-read-chunk-streams</code>
== 0</h3>
<p>Rclone will start reading a chunk of size
<code>--vfs-read-chunk-size</code>, and then double the size for each
read. When <code>--vfs-read-chunk-size-limit</code> is specified, and
greater than <code>--vfs-read-chunk-size</code>, the chunk size for each
open file will get doubled only until the specified value is reached. If
the value is "off", which is the default, the limit is disabled and the
chunk size will grow indefinitely.</p>
<p>With <code>--vfs-read-chunk-size 100M</code> and
<code>--vfs-read-chunk-size-limit 0</code> the following parts will be
downloaded: 0-100M, 100M-200M, 200M-300M, 300M-400M and so on. When
<code>--vfs-read-chunk-size-limit 500M</code> is specified, the result
would be 0-100M, 100M-300M, 300M-700M, 700M-1200M, 1200M-1700M and so
on.</p>
<p>Setting <code>--vfs-read-chunk-size</code> to <code>0</code> or "off"
disables chunked reading.</p>
<p>The chunks will not be buffered in memory.</p>
<h3
id="vfs-read-chunk-streams-0-1"><code>--vfs-read-chunk-streams</code>
&gt; 0</h3>
<p>Rclone reads <code>--vfs-read-chunk-streams</code> chunks of size
<code>--vfs-read-chunk-size</code> concurrently. The size for each read
will stay constant.</p>
<p>This improves performance performance massively on high latency links
or very high bandwidth links to high performance object stores.</p>
<p>Some experimentation will be needed to find the optimum values of
<code>--vfs-read-chunk-size</code> and
<code>--vfs-read-chunk-streams</code> as these will depend on the
backend in use and the latency to the backend.</p>
<p>For high performance object stores (eg AWS S3) a reasonable place to
start might be <code>--vfs-read-chunk-streams 16</code> and
<code>--vfs-read-chunk-size 4M</code>. In testing with AWS S3 the
performance scaled roughly as the <code>--vfs-read-chunk-streams</code>
setting.</p>
<p>Similar settings should work for high latency links, but depending on
the latency they may need more <code>--vfs-read-chunk-streams</code> in
order to get the throughput.</p>
<h2 id="vfs-performance">VFS Performance</h2>
<p>These flags may be used to enable/disable features of the VFS for
performance or other reasons. See also the <a
href="#vfs-chunked-reading">chunked reading</a> feature.</p>
<p>In particular S3 and Swift benefit hugely from the
<code>--no-modtime</code> flag (or use <code>--use-server-modtime</code>
for a slightly different effect) as each read of the modification time
takes a transaction.</p>
<pre class="text"><code>    --no-checksum     Don&#39;t compare checksums on up/download.
    --no-modtime      Don&#39;t read/write the modification time (can speed things up).
    --no-seek         Don&#39;t allow seeking in files.
    --read-only       Only allow read-only access.</code></pre>
<p>Sometimes rclone is delivered reads or writes out of order. Rather
than seeking rclone will wait a short time for the in sequence read or
write to come in. These flags only come into effect when not using an on
disk cache file.</p>
<pre class="text"><code>    --vfs-read-wait duration   Time to wait for in-sequence read before seeking (default 20ms)
    --vfs-write-wait duration  Time to wait for in-sequence write before giving error (default 1s)</code></pre>
<p>When using VFS write caching (<code>--vfs-cache-mode</code> with
value writes or full), the global flag <code>--transfers</code> can be
set to adjust the number of parallel uploads of modified files from the
cache (the related global flag <code>--checkers</code> has no effect on
the VFS).</p>
<pre class="text"><code>    --transfers int  Number of file transfers to run in parallel (default 4)</code></pre>
<h2 id="symlinks">Symlinks</h2>
<p>By default the VFS does not support symlinks. However this may be
enabled with either of the following flags:</p>
<pre class="text"><code>    --links      Translate symlinks to/from regular files with a &#39;.rclonelink&#39; extension.
    --vfs-links  Translate symlinks to/from regular files with a &#39;.rclonelink&#39; extension for the VFS</code></pre>
<p>As most cloud storage systems do not support symlinks directly,
rclone stores the symlink as a normal file with a special extension. So
a file which appears as a symlink <code>link-to-file.txt</code> would be
stored on cloud storage as <code>link-to-file.txt.rclonelink</code> and
the contents would be the path to the symlink destination.</p>
<p>Note that <code>--links</code> enables symlink translation globally
in rclone - this includes any backend which supports the concept (for
example the local backend). <code>--vfs-links</code> just enables it for
the VFS layer.</p>
<p>This scheme is compatible with that used by the <a
href="https://rclone.org/local/#symlinks-junction-points">local backend
with the --local-links flag</a>.</p>
<p>The <code>--vfs-links</code> flag has been designed for
<code>rclone mount</code>, <code>rclone nfsmount</code> and
<code>rclone serve nfs</code>.</p>
<p>It hasn't been tested with the other <code>rclone serve</code>
commands yet.</p>
<p>A limitation of the current implementation is that it expects the
caller to resolve sub-symlinks. For example given this directory
tree</p>
<pre class="text"><code>.
├── dir
│   └── file.txt
└── linked-dir -&gt; dir</code></pre>
<p>The VFS will correctly resolve <code>linked-dir</code> but not
<code>linked-dir/file.txt</code>. This is not a problem for the tested
commands but may be for other commands.</p>
<p><strong>Note</strong> that there is an outstanding issue with symlink
support <a href="https://github.com/rclone/rclone/issues/8245">issue
#8245</a> with duplicate files being created when symlinks are moved
into directories where there is a file of the same name (or vice
versa).</p>
<h2 id="vfs-case-sensitivity">VFS Case Sensitivity</h2>
<p>Linux file systems are case-sensitive: two files can differ only by
case, and the exact case must be used when opening a file.</p>
<p>File systems in modern Windows are case-insensitive but
case-preserving: although existing files can be opened using any case,
the exact case used to create the file is preserved and available for
programs to query. It is not allowed for two files in the same directory
to differ only by case.</p>
<p>Usually file systems on macOS are case-insensitive. It is possible to
make macOS file systems case-sensitive but that is not the default.</p>
<p>The <code>--vfs-case-insensitive</code> VFS flag controls how rclone
handles these two cases. If its value is "false", rclone passes file
names to the remote as-is. If the flag is "true" (or appears without a
value on the command line), rclone may perform a "fixup" as explained
below.</p>
<p>The user may specify a file name to open/delete/rename/etc with a
case different than what is stored on the remote. If an argument refers
to an existing file with exactly the same name, then the case of the
existing file on the disk will be used. However, if a file name with
exactly the same name is not found but a name differing only by case
exists, rclone will transparently fixup the name. This fixup happens
only when an existing file is requested. Case sensitivity of file names
created anew by rclone is controlled by the underlying remote.</p>
<p>Note that case sensitivity of the operating system running rclone
(the target) may differ from case sensitivity of a file system presented
by rclone (the source). The flag controls whether "fixup" is performed
to satisfy the target.</p>
<p>If the flag is not provided on the command line, then its default
value depends on the operating system where rclone runs: "true" on
Windows and macOS, "false" otherwise. If the flag is provided without a
value, then it is "true".</p>
<p>The <code>--no-unicode-normalization</code> flag controls whether a
similar "fixup" is performed for filenames that differ but are <a
href="https://en.wikipedia.org/wiki/Unicode_equivalence">canonically
equivalent</a> with respect to unicode. Unicode normalization can be
particularly helpful for users of macOS, which prefers form NFD instead
of the NFC used by most other platforms. It is therefore highly
recommended to keep the default of <code>false</code> on macOS, to avoid
encoding compatibility issues.</p>
<p>In the (probably unlikely) event that a directory has multiple
duplicate filenames after applying case and unicode normalization, the
<code>--vfs-block-norm-dupes</code> flag allows hiding these duplicates.
This comes with a performance tradeoff, as rclone will have to scan the
entire directory for duplicates when listing a directory. For this
reason, it is recommended to leave this disabled if not needed. However,
macOS users may wish to consider using it, as otherwise, if a remote
directory contains both NFC and NFD versions of the same filename, an
odd situation will occur: both versions of the file will be visible in
the mount, and both will appear to be editable, however, editing either
version will actually result in only the NFD version getting edited
under the hood. <code>--vfs-block- norm-dupes</code> prevents this
confusion by detecting this scenario, hiding the duplicates, and logging
an error, similar to how this is handled in
<code>rclone sync</code>.</p>
<h2 id="vfs-disk-options">VFS Disk Options</h2>
<p>This flag allows you to manually set the statistics about the filing
system. It can be useful when those statistics cannot be read correctly
automatically.</p>
<pre class="text"><code>    --vfs-disk-space-total-size    Manually set the total disk space size (example: 256G, default: -1)</code></pre>
<h2 id="alternate-report-of-used-bytes">Alternate report of used
bytes</h2>
<p>Some backends, most notably S3, do not report the amount of bytes
used. If you need this information to be available when running
<code>df</code> on the filesystem, then pass the flag
<code>--vfs-used-is-size</code> to rclone. With this flag set, instead
of relying on the backend to report this information, rclone will scan
the whole remote similar to <code>rclone size</code> and compute the
total used space itself.</p>
<p><strong>WARNING</strong>: Contrary to <code>rclone size</code>, this
flag ignores filters so that the result is accurate. However, this is
very inefficient and may cost lots of API calls resulting in extra
charges. Use it as a last resort and only with caching.</p>
<h2 id="vfs-metadata">VFS Metadata</h2>
<p>If you use the <code>--vfs-metadata-extension</code> flag you can get
the VFS to expose files which contain the <a
href="https://rclone.org/docs/#metadata">metadata</a> as a JSON blob.
These files will not appear in the directory listing, but can be
<code>stat</code>-ed and opened and once they have been they
<strong>will</strong> appear in directory listings until the directory
cache expires.</p>
<p>Note that some backends won't create metadata unless you pass in the
<code>--metadata</code> flag.</p>
<p>For example, using <code>rclone mount</code> with
<code>--metadata --vfs-metadata-extension .metadata</code> we get</p>
<pre class="console"><code>$ ls -l /mnt/
total 1048577

<h1 id="rclone-moveto">rclone moveto</h1>
<p>Move file or directory from source to dest.</p>
<h2 id="synopsis-60">Synopsis</h2>
<p>If source:path is a file or directory then it moves it to a file or
directory named dest:path.</p>
<p>This can be used to rename files or upload single files to other than
their existing name. If the source is a directory then it acts exactly
like the <a href="https://rclone.org/commands/rclone_move/">move</a>
command.</p>
<p>So</p>
<pre class="console"><code>rclone moveto src dst</code></pre>
<p>where src and dst are rclone paths, either remote:path or
/path/to/local or C:.</p>
<p>This will:</p>
<pre class="text"><code>if src is file
    move it to dst, overwriting an existing file if it exists
if src is directory
    move it to dst, overwriting existing files if they exist
    see move command for full details</code></pre>
<p>This doesn't transfer files that are identical on src and dst,
testing by size and modification time or MD5SUM. src will be deleted on
successful transfer.</p>
<p><strong>Important</strong>: Since this can cause data loss, test
first with the <code>--dry-run</code> or the
<code>--interactive</code>/<code>-i</code> flag.</p>
<p><strong>Note</strong>: Use the
<code>-P</code>/<code>--progress</code> flag to view real-time transfer
statistics.</p>
<h2 id="logger-flags-4">Logger Flags</h2>
<p>The <code>--differ</code>, <code>--missing-on-dst</code>,
<code>--missing-on-src</code>, <code>--match</code> and
<code>--error</code> flags write paths, one per line, to the file name
(or stdout if it is <code>-</code>) supplied. What they write is
described in the help below. For example <code>--differ</code> will
write all paths which are present on both the source and destination but
different.</p>
<p>The <code>--combined</code> flag will write a file (or stdout) which
contains all file paths with a symbol and then a space and then the path
to tell you what happened to it. These are reminiscent of diff
files.</p>
<ul>
<li><code>= path</code> means path was found in source and destination
and was identical</li>
<li><code>- path</code> means path was missing on the source, so only in
the destination</li>
<li><code>+ path</code> means path was missing on the destination, so
only in the source</li>
<li><code>* path</code> means path was present in source and destination
but different.</li>
<li><code>! path</code> means there was an error reading or hashing the
source or dest.</li>
</ul>
<p>The <code>--dest-after</code> flag writes a list file using the same
format flags as <a
href="https://rclone.org/commands/rclone_lsf/#synopsis"><code>lsf</code></a>
(including <a
href="https://rclone.org/commands/rclone_lsf/#synopsis">customizable
options for hash, modtime, etc.</a>) Conceptually it is similar to
rsync's <code>--itemize-changes</code>, but not identical -- it should
output an accurate list of what will be on the destination after the
command is finished.</p>
<p>When the <code>--no-traverse</code> flag is set, all logs involving
files that exist only on the destination will be incomplete or
completely missing.</p>
<p>Note that these logger flags have a few limitations, and certain
scenarios are not currently supported:</p>
<ul>
<li><code>--max-duration</code> / <code>CutoffModeHard</code></li>
<li><code>--compare-dest</code> / <code>--copy-dest</code></li>
<li>server-side moves of an entire dir at once</li>
<li>High-level retries, because there would be duplicates (use
<code>--retries 1</code> to disable)</li>
<li>Possibly some unusual error scenarios</li>
</ul>
<p>Note also that each file is logged during execution, as opposed to
after, so it is most useful as a predictor of what SHOULD happen to each
file (which may or may not match what actually DID).</p>

<p>Explore a remote with a text based user interface.</p>
<h2 id="synopsis-61">Synopsis</h2>
<p>This displays a text based user interface allowing the navigation of
a remote. It is most useful for answering the question - "What is using
all my disk space?".</p>
<p>To make the user interface it first scans the entire remote given and
builds an in memory representation. rclone ncdu can be used during this
scanning phase and you will see it building up the directory structure
as it goes along.</p>
<p>You can interact with the user interface using key presses, press '?'
to toggle the help on and off. The supported keys are:</p>
<pre class="text"><code> ↑,↓ or k,j to Move
 →,l to enter
 ←,h to return
 g toggle graph
 c toggle counts
 a toggle average size in directory
 m toggle modified time
 u toggle human-readable format

 d delete file/directory
 v select file/directory
 V enter visual select mode
 D delete selected files/directories
 y copy current path to clipboard
 Y display current path
 ^L refresh screen (fix screen corruption)
 r recalculate file sizes

<p>Listed files/directories may be prefixed by a one-character flag,
some of them combined with a description in brackets at end of line.
These flags have the following meaning:</p>
<pre class="text"><code>e means this is an empty directory, i.e. contains no files (but
  may contain empty subdirectories)
~ means this is a directory where some of the files (possibly in
  subdirectories) have unknown size, and therefore the directory
  size may be underestimated (and average size inaccurate, as it
  is average of the files with known sizes).
. means an error occurred while reading a subdirectory, and
  therefore the directory size may be underestimated (and average
  size inaccurate)
! means an error occurred while reading this directory</code></pre>
<p>This an homage to the <a href="https://dev.yorhel.nl/ncdu">ncdu
tool</a> but for rclone remotes. It is missing lots of features at the
moment but is useful as it stands. Unlike ncdu it does not show excluded
files.</p>
<p>Note that it might take some time to delete big files/directories.
The UI won't respond in the meantime since the deletion is done
synchronously.</p>
<p>For a non-interactive listing of the remote, see the <a

<h1 id="rclone-nfsmount">rclone nfsmount</h1>
<p>Mount the remote as file system on a mountpoint.</p>
<h2 id="synopsis-62">Synopsis</h2>
<p>Rclone nfsmount allows Linux, FreeBSD, macOS and Windows to mount any
of Rclone's cloud storage systems as a file system with FUSE.</p>
<p>First set up your remote using <code>rclone config</code>. Check it
works with <code>rclone ls</code> etc.</p>
<p>On Linux and macOS, you can run mount in either foreground or
background (aka daemon) mode. Mount runs in foreground mode by default.
Use the <code>--daemon</code> flag to force background mode. On Windows
you can run mount in foreground only, the flag is ignored.</p>
<p>In background mode rclone acts as a generic Unix mount program: the
main program starts, spawns background rclone process to setup and
maintain the mount, waits until success or timeout and exits with
appropriate code (killing the child process if it fails).</p>
<p>On Linux/macOS/FreeBSD start the mount like this, where
<code>/path/to/local/mount</code> is an <strong>empty</strong>
<strong>existing</strong> directory:</p>
<pre class="console"><code>rclone nfsmount remote:path/to/files /path/to/local/mount</code></pre>
<p>On Windows you can start a mount in different ways. See <a
href="#mounting-modes-on-windows">below</a> for details. If foreground
mount is used interactively from a console window, rclone will serve the
mount and occupy the console so another window should be used to work
with the mount until rclone is interrupted e.g. by pressing Ctrl-C.</p>
<p>The following examples will mount to an automatically assigned drive,
to specific drive letter <code>X:</code>, to path
<code>C:\path\parent\mount</code> (where parent directory or drive must
exist, and mount must <strong>not</strong> exist, and is not supported
when <a href="#mounting-modes-on-windows">mounting as a network
drive</a>), and the last example will mount as network share
<code>\\cloud\remote</code> and map it to an automatically assigned
drive:</p>
<pre class="console"><code>rclone nfsmount remote:path/to/files *
rclone nfsmount remote:path/to/files X:
rclone nfsmount remote:path/to/files C:\path\parent\mount
rclone nfsmount remote:path/to/files \\cloud\remote</code></pre>
<p>When the program ends while in foreground mode, either via Ctrl+C or
receiving a SIGINT or SIGTERM signal, the mount should be automatically
stopped.</p>
<p>When running in background mode the user will have to stop the mount
manually:</p>
<pre class="console"><code># Linux
fusermount -u /path/to/local/mount
#... or on some systems
fusermount3 -u /path/to/local/mount
# OS X or Linux when using nfsmount
umount /path/to/local/mount</code></pre>
<p>The umount operation can fail, for example when the mountpoint is
busy. When that happens, it is the user's responsibility to stop the
mount manually.</p>
<p>The size of the mounted file system will be set according to
information retrieved from the remote, the same as returned by the <a
href="https://rclone.org/commands/rclone_about/">rclone about</a>
command. Remotes with unlimited storage may report the used size only,
then an additional 1 PiB of free space is assumed. If the remote does
not <a href="https://rclone.org/overview/#optional-features">support</a>
the about feature at all, then 1 PiB is set as both the total and the
free size.</p>
<h2 id="installing-on-windows-1">Installing on Windows</h2>
<p>To run <code>rclone nfsmount on Windows</code>, you will need to
download and install <a
href="http://www.secfs.net/winfsp/">WinFsp</a>.</p>
<p><a href="https://github.com/winfsp/winfsp">WinFsp</a> is an
open-source Windows File System Proxy which makes it easy to write user
space file systems for Windows. It provides a FUSE emulation layer which
rclone uses combination with <a
href="https://github.com/winfsp/cgofuse">cgofuse</a>. Both of these
packages are by Bill Zissimopoulos who was very helpful during the
implementation of rclone nfsmount for Windows.</p>
<h3 id="mounting-modes-on-windows-1">Mounting modes on windows</h3>
<p>Unlike other operating systems, Microsoft Windows provides a
different filesystem type for network and fixed drives. It optimises
access on the assumption fixed disk drives are fast and reliable, while
network drives have relatively high latency and less reliability. Some
settings can also be differentiated between the two types, for example
that Windows Explorer should just display icons and not create preview
thumbnails for image and video files on network drives.</p>
<p>In most cases, rclone will mount the remote as a normal, fixed disk
drive by default. However, you can also choose to mount it as a remote
network drive, often described as a network share. If you mount an
rclone remote using the default, fixed drive mode and experience
unexpected program errors, freezes or other issues, consider mounting as
a network drive instead.</p>
<p>When mounting as a fixed disk drive you can either mount to an unused
drive letter, or to a path representing a <strong>nonexistent</strong>
subdirectory of an <strong>existing</strong> parent directory or drive.
Using the special value <code>*</code> will tell rclone to automatically
assign the next available drive letter, starting with Z: and moving
backward. Examples:</p>
<pre class="console"><code>rclone nfsmount remote:path/to/files *
rclone nfsmount remote:path/to/files X:
rclone nfsmount remote:path/to/files C:\path\parent\mount
rclone nfsmount remote:path/to/files X:</code></pre>
<p>Option <code>--volname</code> can be used to set a custom volume name
for the mounted file system. The default is to use the remote name and
path.</p>
<p>To mount as network drive, you can add option
<code>--network-mode</code> to your nfsmount command. Mounting to a
directory path is not supported in this mode, it is a limitation Windows
imposes on junctions, so the remote must always be mounted to a drive
letter.</p>
<pre class="console"><code>rclone nfsmount remote:path/to/files X: --network-mode</code></pre>
<p>A volume name specified with <code>--volname</code> will be used to
create the network share path. A complete UNC path, such as
<code>\\cloud\remote</code>, optionally with path
<code>\\cloud\remote\madeup\path</code>, will be used as is. Any other
string will be used as the share part, after a default prefix
<code>\\server\</code>. If no volume name is specified then
<code>\\server\share</code> will be used. You must make sure the volume
name is unique when you are mounting more than one drive, or else the
mount command will fail. The share name will treated as the volume label
for the mapped drive, shown in Windows Explorer etc, while the complete
<code>\\server\share</code> will be reported as the remote UNC path by
<code>net use</code> etc, just like a normal network drive mapping.</p>
<p>If you specify a full network share UNC path with
<code>--volname</code>, this will implicitly set the
<code>--network-mode</code> option, so the following two examples have
same result:</p>
<pre class="console"><code>rclone nfsmount remote:path/to/files X: --network-mode
rclone nfsmount remote:path/to/files X: --volname \\server\share</code></pre>
<p>You may also specify the network share UNC path as the mountpoint
itself. Then rclone will automatically assign a drive letter, same as
with <code>*</code> and use that as mountpoint, and instead use the UNC
path specified as the volume name, as if it were specified with the
<code>--volname</code> option. This will also implicitly set the
<code>--network-mode</code> option. This means the following two
examples have same result:</p>
<pre class="console"><code>rclone nfsmount remote:path/to/files \\cloud\remote
rclone nfsmount remote:path/to/files * --volname \\cloud\remote</code></pre>
<p>There is yet another way to enable network mode, and to set the share
path, and that is to pass the "native" libfuse/WinFsp option directly:
<code>--fuse-flag --VolumePrefix=\server\share</code>. Note that the
path must be with just a single backslash prefix in this case.</p>
<p><em>Note:</em> In previous versions of rclone this was the only
supported method.</p>

<h3 id="windows-filesystem-permissions-1">Windows filesystem
permissions</h3>
<p>The FUSE emulation layer on Windows must convert between the
POSIX-based permission model used in FUSE, and the permission model used
in Windows, based on access-control lists (ACL).</p>
<p>The mounted filesystem will normally get three entries in its
access-control list (ACL), representing permissions for the POSIX
permission scopes: Owner, group and others. By default, the owner and
group will be taken from the current user, and the built-in group
"Everyone" will be used to represent others. The user/group can be
customized with FUSE options "UserName" and "GroupName", e.g.
<code>-o UserName=user123 -o GroupName="Authenticated Users"</code>. The
permissions on each entry will be set according to <a
href="#options">options</a> <code>--dir-perms</code> and
<code>--file-perms</code>, which takes a value in traditional Unix <a
href="https://en.wikipedia.org/wiki/File-system_permissions#Numeric_notation">numeric
notation</a>.</p>
<p>The default permissions corresponds to
<code>--file-perms 0666 --dir-perms 0777</code>, i.e. read and write
permissions to everyone. This means you will not be able to start any
programs from the mount. To be able to do that you must add execute
permissions, e.g. <code>--file-perms 0777 --dir-perms 0777</code> to add
it to everyone. If the program needs to write files, chances are you
will have to enable <a href="#vfs-file-caching">VFS File Caching</a> as
well (see also <a href="#limitations">limitations</a>). Note that the
default write permission have some restrictions for accounts other than
the owner, specifically it lacks the "write extended attributes", as
explained next.</p>
<p>The mapping of permissions is not always trivial, and the result you
see in Windows Explorer may not be exactly like you expected. For
example, when setting a value that includes write access for the group
or others scope, this will be mapped to individual permissions "write
attributes", "write data" and "append data", but not "write extended
attributes". Windows will then show this as basic permission "Special"
instead of "Write", because "Write" also covers the "write extended
attributes" permission. When setting digit 0 for group or others, to
indicate no permissions, they will still get individual permissions
"read attributes", "read extended attributes" and "read permissions".
This is done for compatibility reasons, e.g. to allow users without
additional permissions to be able to read basic metadata about files
like in Unix.</p>
<p>WinFsp 2021 (version 1.9) introduced a new FUSE option
"FileSecurity", that allows the complete specification of file security
descriptors using <a
href="https://docs.microsoft.com/en-us/windows/win32/secauthz/security-descriptor-string-format">SDDL</a>.
With this you get detailed control of the resulting permissions,
compared to use of the POSIX permissions described above, and no
additional permissions will be added automatically for compatibility
with Unix. Some example use cases will following.</p>
<p>If you set POSIX permissions for only allowing access to the owner,
using <code>--file-perms 0600 --dir-perms 0700</code>, the user group
and the built-in "Everyone" group will still be given some special
permissions, as described above. Some programs may then (incorrectly)
interpret this as the file being accessible by everyone, for example an
SSH client may warn about "unprotected private key file". You can work
around this by specifying
<code>-o FileSecurity="D:P(A;;FA;;;OW)"</code>, which sets file all
access (FA) to the owner (OW), and nothing else.</p>
<p>When setting write permissions then, except for the owner, this does
not include the "write extended attributes" permission, as mentioned
above. This may prevent applications from writing to files, giving
permission denied error instead. To set working write permissions for
the built-in "Everyone" group, similar to what it gets by default but
with the addition of the "write extended attributes", you can specify
<code>-o FileSecurity="D:P(A;;FRFW;;;WD)"</code>, which sets file read
(FR) and file write (FW) to everyone (WD). If file execute (FX) is also
needed, then change to
<code>-o FileSecurity="D:P(A;;FRFWFX;;;WD)"</code>, or set file all
access (FA) to get full access permissions, including delete, with
<code>-o FileSecurity="D:P(A;;FA;;;WD)"</code>.</p>
<h3 id="windows-caveats-1">Windows caveats</h3>
<p>Drives created as Administrator are not visible to other accounts,
not even an account that was elevated to Administrator with the User
Account Control (UAC) feature. A result of this is that if you mount to
a drive letter from a Command Prompt run as Administrator, and then try
to access the same drive from Windows Explorer (which does not run as
Administrator), you will not be able to see the mounted drive.</p>
<p>If you don't need to access the drive from applications running with
administrative privileges, the easiest way around this is to always
create the mount from a non-elevated command prompt.</p>
<p>To make mapped drives available to the user account that created them
regardless if elevated or not, there is a special Windows setting called
<a
href="https://docs.microsoft.com/en-us/troubleshoot/windows-client/networking/mapped-drives-not-available-from-elevated-command#detail-to-configure-the-enablelinkedconnections-registry-entry">linked
connections</a> that can be enabled.</p>
<p>It is also possible to make a drive mount available to everyone on
the system, by running the process creating it as the built-in SYSTEM
account. There are several ways to do this: One is to use the
command-line utility <a
href="https://docs.microsoft.com/en-us/sysinternals/downloads/psexec">PsExec</a>,
from Microsoft's Sysinternals suite, which has option <code>-s</code> to
start processes as the SYSTEM account. Another alternative is to run the
mount command from a Windows Scheduled Task, or a Windows Service,
configured to run as the SYSTEM account. A third alternative is to use
the <a
href="https://github.com/winfsp/winfsp/wiki/WinFsp-Service-Architecture">WinFsp.Launcher
infrastructure</a>). Read more in the <a
href="https://rclone.org/install/">install documentation</a>. Note that
when running rclone as another user, it will not use the configuration
file from your profile unless you tell it to with the <a
href="https://rclone.org/docs/#config-string"><code>--config</code></a>
option. Note also that it is now the SYSTEM account that will have the
owner permissions, and other accounts will have permissions according to
the group or others scopes. As mentioned above, these will then not get
the "write extended attributes" permission, and this may prevent writing
to files. You can work around this with the FileSecurity option, see
example above.</p>
<p>Note that mapping to a directory path, instead of a drive letter,
does not suffer from the same limitations.</p>
<h2 id="mounting-on-macos-1">Mounting on macOS</h2>
<p>Mounting on macOS can be done either via <a
href="https://rclone.org/commands/rclone_serve_nfs/">built-in NFS
server</a>, <a href="https://osxfuse.github.io/">macFUSE</a> (also known
as osxfuse) or <a href="https://www.fuse-t.org/">FUSE-T</a>.macFUSE is a
traditional FUSE driver utilizing a macOS kernel extension (kext).
FUSE-T is an alternative FUSE system which "mounts" via an NFSv4 local
server.</p>
<h3 id="unicode-normalization-1">Unicode Normalization</h3>
<p>It is highly recommended to keep the default of
<code>--no-unicode-normalization=false</code> for all <code>mount</code>
and <code>serve</code> commands on macOS. For details, see <a
href="https://rclone.org/commands/rclone_mount/#vfs-case-sensitivity">vfs-case-sensitivity</a>.</p>
<h3 id="nfs-mount-1">NFS mount</h3>
<p>This method spins up an NFS server using <a
href="https://rclone.org/commands/rclone_serve_nfs/">serve nfs</a>
command and mounts it to the specified mountpoint. If you run this in
background mode using |--daemon|, you will need to send SIGTERM signal
to the rclone process using |kill| command to stop the mount.</p>
<p>Note that <code>--nfs-cache-handle-limit</code> controls the maximum
number of cached file handles stored by the <code>nfsmount</code>
caching handler. This should not be set too low or you may experience
errors when trying to access files. The default is 1000000, but consider
lowering this limit if the server's system resource usage causes
problems.</p>
<h3 id="macfuse-notes-1">macFUSE Notes</h3>
<p>If installing macFUSE using <a
href="https://github.com/osxfuse/osxfuse/releases">dmg packages</a> from
the website, rclone will locate the macFUSE libraries without any
further intervention. If however, macFUSE is installed using the <a
href="https://www.macports.org/">macports</a> package manager, the
following addition steps are required.</p>
<pre class="console"><code>sudo mkdir /usr/local/lib
cd /usr/local/lib
sudo ln -s /opt/local/lib/libfuse.2.dylib</code></pre>
<h3 id="fuse-t-limitations-caveats-and-notes-1">FUSE-T Limitations,
Caveats, and Notes</h3>
<p>There are some limitations, caveats, and notes about how it works.
These are current as of FUSE-T version 1.0.14.</p>
<h4 id="modtime-update-on-read-1">ModTime update on read</h4>
<p>As per the <a
href="https://github.com/macos-fuse-t/fuse-t/wiki#caveats">FUSE-T
wiki</a>:</p>
<blockquote>
<p>File access and modification times cannot be set separately as it
seems to be an issue with the NFS client which always modifies both. Can
be reproduced with 'touch -m' and 'touch -a' commands</p>
</blockquote>
<p>This means that viewing files with various tools, notably macOS
Finder, will cause rlcone to update the modification time of the file.
This may make rclone upload a full new copy of the file.</p>
<h4 id="read-only-mounts-1">Read Only mounts</h4>
<p>When mounting with <code>--read-only</code>, attempts to write to
files will fail <em>silently</em> as opposed to with a clear warning as
in macFUSE.</p>
<h1 id="mounting-on-linux-1">Mounting on Linux</h1>
<p>On newer versions of Ubuntu, you may encounter the following error
when running <code>rclone mount</code>:</p>
<blockquote>
<p>NOTICE: mount helper error: fusermount3: mount failed: Permission
denied CRITICAL: Fatal error: failed to mount FUSE fs: fusermount: exit
status 1 This may be due to newer <a
href="https://wiki.ubuntu.com/AppArmor">Apparmor</a> restrictions, which
can be disabled with <code>sudo aa-disable /usr/bin/fusermount3</code>
(you may need to <code>sudo apt install apparmor-utils</code>
beforehand).</p>
</blockquote>
<h2 id="limitations-1">Limitations</h2>
<p>Without the use of <code>--vfs-cache-mode</code> this can only write
files sequentially, it can only seek when reading. This means that many
applications won't work with their files on an rclone mount without
<code>--vfs-cache-mode writes</code> or
<code>--vfs-cache-mode full</code>. See the <a
href="#vfs-file-caching">VFS File Caching</a> section for more info.
When using NFS mount on macOS, if you don't specify |--vfs-cache-mode|
the mount point will be read-only.</p>
<p>Bucket-based remotes - Azure Blob, Swift, S3, Google Cloud Storage
and B2 - can't store empty directories. Of these, only Azure Blob,
Google Cloud Storage and S3 can preserve them when you add
<code>--xxx-directory_markers</code>; otherwise, empty directories will
vanish once they drop out of the directory cache.</p>
<p>When <code>rclone mount</code> is invoked on Unix with
<code>--daemon</code> flag, the main rclone program will wait for the
background mount to become ready or until the timeout specified by the
<code>--daemon-wait</code> flag. On Linux it can check mount status
using ProcFS so the flag in fact sets <strong>maximum</strong> time to
wait, while the real wait can be less. On macOS / BSD the time to wait
is constant and the check is performed only at the end. We advise you to
set wait time on macOS reasonably.</p>
<p>Only supported on Linux, FreeBSD, OS X and Windows at the moment.</p>
<h2 id="rclone-nfsmount-vs-rclone-synccopy">rclone nfsmount vs rclone
sync/copy</h2>
<p>File systems expect things to be 100% reliable, whereas cloud storage
systems are a long way from 100% reliable. The rclone sync/copy commands
cope with this with lots of retries. However rclone nfsmount can't use
retries in the same way without making local copies of the uploads. Look
at the <a href="#vfs-file-caching">VFS File Caching</a> for solutions to
make nfsmount more reliable.</p>
<h2 id="attribute-caching-1">Attribute caching</h2>
<p>You can use the flag <code>--attr-timeout</code> to set the time the
kernel caches the attributes (size, modification time, etc.) for
directory entries.</p>
<p>The default is <code>1s</code> which caches files just long enough to
avoid too many callbacks to rclone from the kernel.</p>
<p>In theory 0s should be the correct value for filesystems which can
change outside the control of the kernel. However this causes quite a
few problems such as <a
href="https://github.com/rclone/rclone/issues/2157">rclone using too
much memory</a>, <a
href="https://forum.rclone.org/t/rclone-1-39-vs-1-40-mount-issue/5112">rclone
not serving files to samba</a> and <a
href="https://github.com/rclone/rclone/issues/2095#issuecomment-371141147">excessive
time listing directories</a>.</p>
<p>The kernel can cache the info about a file for the time given by
<code>--attr-timeout</code>. You may see corruption if the remote file
changes length during this window. It will show up as either a truncated
file or a file with garbage on the end. With
<code>--attr-timeout 1s</code> this is very unlikely but not impossible.
The higher you set <code>--attr-timeout</code> the more likely it is.
The default setting of "1s" is the lowest setting which mitigates the
problems above.</p>
<p>If you set it higher (<code>10s</code> or <code>1m</code> say) then
the kernel will call back to rclone less often making it more efficient,
however there is more chance of the corruption issue above.</p>
<p>If files don't change on the remote outside of the control of rclone
then there is no chance of corruption.</p>
<p>This is the same as setting the attr_timeout option in
mount.fuse.</p>
<h2 id="filters-1">Filters</h2>
<p>Note that all the rclone filters can be used to select a subset of
the files to be visible in the mount.</p>
<h2 id="systemd-1">systemd</h2>
<p>When running rclone nfsmount as a systemd service, it is possible to
use Type=notify. In this case the service will enter the started state
after the mountpoint has been successfully set up. Units having the
rclone nfsmount service specified as a requirement will see all files
and folders immediately in this mode.</p>
<p>Note that systemd runs mount units without any environment variables
including <code>PATH</code> or <code>HOME</code>. This means that tilde
(<code>~</code>) expansion will not work and you should provide
<code>--config</code> and <code>--cache-dir</code> explicitly as
absolute paths via rclone arguments. Since mounting requires the
<code>fusermount</code> or <code>fusermount3</code> program, rclone will
use the fallback PATH of <code>/bin:/usr/bin</code> in this scenario.
Please ensure that <code>fusermount</code>/<code>fusermount3</code> is
present on this PATH.</p>
<h2 id="rclone-as-unix-mount-helper-1">Rclone as Unix mount helper</h2>
<p>The core Unix program <code>/bin/mount</code> normally takes the
<code>-t FSTYPE</code> argument then runs the
<code>/sbin/mount.FSTYPE</code> helper program passing it mount options
as <code>-o key=val,...</code> or <code>--opt=...</code>. Automount
(classic or systemd) behaves in a similar way.</p>
<p>rclone by default expects GNU-style flags <code>--key val</code>. To
run it as a mount helper you should symlink rclone binary to
<code>/sbin/mount.rclone</code> and optionally
<code>/usr/bin/rclonefs</code>, e.g.
<code>ln -s /usr/bin/rclone /sbin/mount.rclone</code>. rclone will
detect it and translate command-line arguments appropriately.</p>
<p>Now you can run classic mounts like this:</p>
<pre class="console"><code>mount sftp1:subdir /mnt/data -t rclone -o vfs_cache_mode=writes,sftp_key_file=/path/to/pem</code></pre>
<p>or create systemd mount units:</p>

<p>or add in <code>/etc/fstab</code> a line like</p>

<p>or use classic Automountd. Remember to provide explicit
<code>config=...,cache-dir=...</code> as a workaround for mount units
being run without <code>HOME</code>.</p>
<p>Rclone in the mount helper mode will split <code>-o</code>
argument(s) by comma, replace <code>_</code> by <code>-</code> and
prepend <code>--</code> to get the command-line flags. Options
containing commas or spaces can be wrapped in single or double quotes.
Any inner quotes inside outer quotes of the same type should be
doubled.</p>
<p>Mount option syntax includes a few extra options treated
specially:</p>
<ul>
<li><code>env.NAME=VALUE</code> will set an environment variable for the
mount process. This helps with Automountd and Systemd.mount which don't
allow setting custom environment for mount helpers. Typically you will
use <code>env.HTTPS_PROXY=proxy.host:3128</code> or
<code>env.HOME=/root</code></li>
<li><code>command=cmount</code> can be used to run <code>cmount</code>
or any other rclone command rather than the default
<code>mount</code>.</li>
<li><code>args2env</code> will pass mount options to the mount helper
running in background via environment variables instead of command line
arguments. This allows to hide secrets from such commands as
<code>ps</code> or <code>pgrep</code>.</li>
<li><code>vv...</code> will be transformed into appropriate
<code>--verbose=N</code></li>
<li>standard mount options like <code>x-systemd.automount</code>,
<code>_netdev</code>, <code>nosuid</code> and alike are intended only
for Automountd and ignored by rclone.</li>
</ul>
<h2 id="vfs---virtual-file-system-1">VFS - Virtual File System</h2>
<p>This command uses the VFS layer. This adapts the cloud storage
objects that rclone uses into something which looks much more like a
disk filing system.</p>
<p>Cloud storage objects have lots of properties which aren't like disk
files - you can't extend them or write to the middle of them, so the VFS
layer has to deal with that. Because there is no one right way of doing
this there are various options explained below.</p>
<p>The VFS layer also implements a directory cache - this caches info
about files and directories (but not the data) in memory.</p>
<h2 id="vfs-directory-cache-1">VFS Directory Cache</h2>
<p>Using the <code>--dir-cache-time</code> flag, you can control how
long a directory should be considered up to date and not refreshed from
the backend. Changes made through the VFS will appear immediately or
invalidate the cache.</p>
<pre class="text"><code>    --dir-cache-time duration   Time to cache directory entries for (default 5m0s)
    --poll-interval duration    Time to wait between polling for changes. Must be smaller than dir-cache-time. Only on supported remotes. Set to 0 to disable (default 1m0s)</code></pre>
<p>However, changes made directly on the cloud storage by the web
interface or a different copy of rclone will only be picked up once the
directory cache expires if the backend configured does not support
polling for changes. If the backend supports polling, changes will be
picked up within the polling interval.</p>
<p>You can send a <code>SIGHUP</code> signal to rclone for it to flush
all directory caches, regardless of how old they are. Assuming only one
rclone instance is running, you can reset the cache like this:</p>
<pre class="console"><code>kill -SIGHUP $(pidof rclone)</code></pre>
<p>If you configure rclone with a <a href="/rc">remote control</a> then
you can use rclone rc to flush the whole directory cache:</p>
<pre class="console"><code>rclone rc vfs/forget</code></pre>
<p>Or individual files or directories:</p>
<pre class="console"><code>rclone rc vfs/forget file=path/to/file dir=path/to/dir</code></pre>
<h2 id="vfs-file-buffering-1">VFS File Buffering</h2>
<p>The <code>--buffer-size</code> flag determines the amount of memory,
that will be used to buffer data in advance.</p>
<p>Each open file will try to keep the specified amount of data in
memory at all times. The buffered data is bound to one open file and
won't be shared.</p>
<p>This flag is a upper limit for the used memory per open file. The
buffer will only use memory for data that is downloaded but not not yet
read. If the buffer is empty, only a small amount of memory will be
used.</p>
<p>The maximum memory used by rclone for buffering can be up to
<code>--buffer-size * open files</code>.</p>
<h2 id="vfs-file-caching-1">VFS File Caching</h2>
<p>These flags control the VFS file caching options. File caching is
necessary to make the VFS layer appear compatible with a normal file
system. It can be disabled at the cost of some compatibility.</p>
<p>For example you'll need to enable VFS caching if you want to read and
write simultaneously to a file. See below for more details.</p>
<p>Note that the VFS cache is separate from the cache backend and you
may find that you need one or the other or both.</p>
<pre class="text"><code>    --cache-dir string                     Directory rclone will use for caching.
    --vfs-cache-mode CacheMode             Cache mode off|minimal|writes|full (default off)
    --vfs-cache-max-age duration           Max time since last access of objects in the cache (default 1h0m0s)
    --vfs-cache-max-size SizeSuffix        Max total size of objects in the cache (default off)
    --vfs-cache-min-free-space SizeSuffix  Target minimum free space on the disk containing the cache (default off)
    --vfs-cache-poll-interval duration     Interval to poll the cache for stale objects (default 1m0s)
    --vfs-write-back duration              Time to writeback files after last use when using cache (default 5s)</code></pre>
<p>If run with <code>-vv</code> rclone will print the location of the
file cache. The files are stored in the user cache file area which is OS
dependent but can be controlled with <code>--cache-dir</code> or setting
the appropriate environment variable.</p>
<p>The cache has 4 different modes selected by
<code>--vfs-cache-mode</code>. The higher the cache mode the more
compatible rclone becomes at the cost of using disk space.</p>
<p>Note that files are written back to the remote only when they are
closed and if they haven't been accessed for
<code>--vfs-write-back</code> seconds. If rclone is quit or dies with
files that haven't been uploaded, these will be uploaded next time
rclone is run with the same flags.</p>
<p>If using <code>--vfs-cache-max-size</code> or
<code>--vfs-cache-min-free-space</code> note that the cache may exceed
these quotas for two reasons. Firstly because it is only checked every
<code>--vfs-cache-poll-interval</code>. Secondly because open files
cannot be evicted from the cache. When <code>--vfs-cache-max-size</code>
or <code>--vfs-cache-min-free-space</code> is exceeded, rclone will
attempt to evict the least accessed files from the cache first. rclone
will start with files that haven't been accessed for the longest. This
cache flushing strategy is efficient and more relevant files are likely
to remain cached.</p>
<p>The <code>--vfs-cache-max-age</code> will evict files from the cache
after the set time since last access has passed. The default value of 1
hour will start evicting files from cache that haven't been accessed for
1 hour. When a cached file is accessed the 1 hour timer is reset to 0
and will wait for 1 more hour before evicting. Specify the time with
standard notation, s, m, h, d, w .</p>
<p>You <strong>should not</strong> run two copies of rclone using the
same VFS cache with the same or overlapping remotes if using
<code>--vfs-cache-mode &gt; off</code>. This can potentially cause data
corruption if you do. You can work around this by giving each rclone its
own cache hierarchy with <code>--cache-dir</code>. You don't need to
worry about this if the remotes in use don't overlap.</p>
<h3 id="vfs-cache-mode-off-1">--vfs-cache-mode off</h3>
<p>In this mode (the default) the cache will read directly from the
remote and write directly to the remote without caching anything on
disk.</p>
<p>This will mean some operations are not possible</p>
<ul>
<li>Files can't be opened for both read AND write</li>
<li>Files opened for write can't be seeked</li>
<li>Existing files opened for write must have O_TRUNC set</li>
<li>Files open for read with O_TRUNC will be opened write only</li>
<li>Files open for write only will behave as if O_TRUNC was
supplied</li>
<li>Open modes O_APPEND, O_TRUNC are ignored</li>
<li>If an upload fails it can't be retried</li>
</ul>
<h3 id="vfs-cache-mode-minimal-1">--vfs-cache-mode minimal</h3>
<p>This is very similar to "off" except that files opened for read AND
write will be buffered to disk. This means that files opened for write
will be a lot more compatible, but uses the minimal disk space.</p>
<p>These operations are not possible</p>
<ul>
<li>Files opened for write only can't be seeked</li>
<li>Existing files opened for write must have O_TRUNC set</li>
<li>Files opened for write only will ignore O_APPEND, O_TRUNC</li>
<li>If an upload fails it can't be retried</li>
</ul>
<h3 id="vfs-cache-mode-writes-1">--vfs-cache-mode writes</h3>
<p>In this mode files opened for read only are still read directly from
the remote, write only and read/write files are buffered to disk
first.</p>
<p>This mode should support all normal file system operations.</p>
<p>If an upload fails it will be retried at exponentially increasing
intervals up to 1 minute.</p>
<h3 id="vfs-cache-mode-full-1">--vfs-cache-mode full</h3>
<p>In this mode all reads and writes are buffered to and from disk. When
data is read from the remote this is buffered to disk as well.</p>
<p>In this mode the files in the cache will be sparse files and rclone
will keep track of which bits of the files it has downloaded.</p>
<p>So if an application only reads the starts of each file, then rclone
will only buffer the start of the file. These files will appear to be
their full size in the cache, but they will be sparse files with only
the data that has been downloaded present in them.</p>
<p>This mode should support all normal file system operations and is
otherwise identical to <code>--vfs-cache-mode</code> writes.</p>
<p>When reading a file rclone will read <code>--buffer-size</code> plus
<code>--vfs-read-ahead</code> bytes ahead. The
<code>--buffer-size</code> is buffered in memory whereas the
<code>--vfs-read-ahead</code> is buffered on disk.</p>
<p>When using this mode it is recommended that
<code>--buffer-size</code> is not set too large and
<code>--vfs-read-ahead</code> is set large if required.</p>
<p><strong>IMPORTANT</strong> not all file systems support sparse files.
In particular FAT/exFAT do not. Rclone will perform very badly if the
cache directory is on a filesystem which doesn't support sparse files
and it will log an ERROR message if one is detected.</p>
<h3 id="fingerprinting-1">Fingerprinting</h3>
<p>Various parts of the VFS use fingerprinting to see if a local file
copy has changed relative to a remote file. Fingerprints are made
from:</p>
<ul>
<li>size</li>
<li>modification time</li>
<li>hash</li>
</ul>
<p>where available on an object.</p>
<p>On some backends some of these attributes are slow to read (they take
an extra API call per object, or extra work per object).</p>
<p>For example <code>hash</code> is slow with the <code>local</code> and
<code>sftp</code> backends as they have to read the entire file and hash
it, and <code>modtime</code> is slow with the <code>s3</code>,
<code>swift</code>, <code>ftp</code> and <code>qinqstor</code> backends
because they need to do an extra API call to fetch it.</p>
<p>If you use the <code>--vfs-fast-fingerprint</code> flag then rclone
will not include the slow operations in the fingerprint. This makes the
fingerprinting less accurate but much faster and will improve the
opening time of cached files.</p>
<p>If you are running a vfs cache over <code>local</code>,
<code>s3</code> or <code>swift</code> backends then using this flag is
recommended.</p>
<p>Note that if you change the value of this flag, the fingerprints of
the files in the cache may be invalidated and the files will need to be
downloaded again.</p>
<h2 id="vfs-chunked-reading-1">VFS Chunked Reading</h2>
<p>When rclone reads files from a remote it reads them in chunks. This
means that rather than requesting the whole file rclone reads the chunk
specified. This can reduce the used download quota for some remotes by
requesting only chunks from the remote that are actually read, at the
cost of an increased number of requests.</p>
<p>These flags control the chunking:</p>
<pre class="text"><code>    --vfs-read-chunk-size SizeSuffix        Read the source objects in chunks (default 128M)
    --vfs-read-chunk-size-limit SizeSuffix  Max chunk doubling size (default off)
    --vfs-read-chunk-streams int            The number of parallel streams to read at once</code></pre>
<p>The chunking behaves differently depending on the
<code>--vfs-read-chunk-streams</code> parameter.</p>
<h3
id="vfs-read-chunk-streams-0-2"><code>--vfs-read-chunk-streams</code> ==
0</h3>
<p>Rclone will start reading a chunk of size
<code>--vfs-read-chunk-size</code>, and then double the size for each
read. When <code>--vfs-read-chunk-size-limit</code> is specified, and
greater than <code>--vfs-read-chunk-size</code>, the chunk size for each
open file will get doubled only until the specified value is reached. If
the value is "off", which is the default, the limit is disabled and the
chunk size will grow indefinitely.</p>
<p>With <code>--vfs-read-chunk-size 100M</code> and
<code>--vfs-read-chunk-size-limit 0</code> the following parts will be
downloaded: 0-100M, 100M-200M, 200M-300M, 300M-400M and so on. When
<code>--vfs-read-chunk-size-limit 500M</code> is specified, the result
would be 0-100M, 100M-300M, 300M-700M, 700M-1200M, 1200M-1700M and so
on.</p>
<p>Setting <code>--vfs-read-chunk-size</code> to <code>0</code> or "off"
disables chunked reading.</p>
<p>The chunks will not be buffered in memory.</p>
<h3
id="vfs-read-chunk-streams-0-3"><code>--vfs-read-chunk-streams</code>
&gt; 0</h3>
<p>Rclone reads <code>--vfs-read-chunk-streams</code> chunks of size
<code>--vfs-read-chunk-size</code> concurrently. The size for each read
will stay constant.</p>
<p>This improves performance performance massively on high latency links
or very high bandwidth links to high performance object stores.</p>
<p>Some experimentation will be needed to find the optimum values of
<code>--vfs-read-chunk-size</code> and
<code>--vfs-read-chunk-streams</code> as these will depend on the
backend in use and the latency to the backend.</p>
<p>For high performance object stores (eg AWS S3) a reasonable place to
start might be <code>--vfs-read-chunk-streams 16</code> and
<code>--vfs-read-chunk-size 4M</code>. In testing with AWS S3 the
performance scaled roughly as the <code>--vfs-read-chunk-streams</code>
setting.</p>
<p>Similar settings should work for high latency links, but depending on
the latency they may need more <code>--vfs-read-chunk-streams</code> in
order to get the throughput.</p>
<h2 id="vfs-performance-1">VFS Performance</h2>
<p>These flags may be used to enable/disable features of the VFS for
performance or other reasons. See also the <a
href="#vfs-chunked-reading">chunked reading</a> feature.</p>
<p>In particular S3 and Swift benefit hugely from the
<code>--no-modtime</code> flag (or use <code>--use-server-modtime</code>
for a slightly different effect) as each read of the modification time
takes a transaction.</p>
<pre class="text"><code>    --no-checksum     Don&#39;t compare checksums on up/download.
    --no-modtime      Don&#39;t read/write the modification time (can speed things up).
    --no-seek         Don&#39;t allow seeking in files.
    --read-only       Only allow read-only access.</code></pre>
<p>Sometimes rclone is delivered reads or writes out of order. Rather
than seeking rclone will wait a short time for the in sequence read or
write to come in. These flags only come into effect when not using an on
disk cache file.</p>
<pre class="text"><code>    --vfs-read-wait duration   Time to wait for in-sequence read before seeking (default 20ms)
    --vfs-write-wait duration  Time to wait for in-sequence write before giving error (default 1s)</code></pre>
<p>When using VFS write caching (<code>--vfs-cache-mode</code> with
value writes or full), the global flag <code>--transfers</code> can be
set to adjust the number of parallel uploads of modified files from the
cache (the related global flag <code>--checkers</code> has no effect on
the VFS).</p>
<pre class="text"><code>    --transfers int  Number of file transfers to run in parallel (default 4)</code></pre>
<h2 id="symlinks-1">Symlinks</h2>
<p>By default the VFS does not support symlinks. However this may be
enabled with either of the following flags:</p>
<pre class="text"><code>    --links      Translate symlinks to/from regular files with a &#39;.rclonelink&#39; extension.
    --vfs-links  Translate symlinks to/from regular files with a &#39;.rclonelink&#39; extension for the VFS</code></pre>
<p>As most cloud storage systems do not support symlinks directly,
rclone stores the symlink as a normal file with a special extension. So
a file which appears as a symlink <code>link-to-file.txt</code> would be
stored on cloud storage as <code>link-to-file.txt.rclonelink</code> and
the contents would be the path to the symlink destination.</p>
<p>Note that <code>--links</code> enables symlink translation globally
in rclone - this includes any backend which supports the concept (for
example the local backend). <code>--vfs-links</code> just enables it for
the VFS layer.</p>
<p>This scheme is compatible with that used by the <a
href="https://rclone.org/local/#symlinks-junction-points">local backend
with the --local-links flag</a>.</p>
<p>The <code>--vfs-links</code> flag has been designed for
<code>rclone mount</code>, <code>rclone nfsmount</code> and
<code>rclone serve nfs</code>.</p>
<p>It hasn't been tested with the other <code>rclone serve</code>
commands yet.</p>
<p>A limitation of the current implementation is that it expects the
caller to resolve sub-symlinks. For example given this directory
tree</p>
<pre class="text"><code>.
├── dir
│   └── file.txt
└── linked-dir -&gt; dir</code></pre>
<p>The VFS will correctly resolve <code>linked-dir</code> but not
<code>linked-dir/file.txt</code>. This is not a problem for the tested
commands but may be for other commands.</p>
<p><strong>Note</strong> that there is an outstanding issue with symlink
support <a href="https://github.com/rclone/rclone/issues/8245">issue
#8245</a> with duplicate files being created when symlinks are moved
into directories where there is a file of the same name (or vice
versa).</p>
<h2 id="vfs-case-sensitivity-1">VFS Case Sensitivity</h2>
<p>Linux file systems are case-sensitive: two files can differ only by
case, and the exact case must be used when opening a file.</p>
<p>File systems in modern Windows are case-insensitive but
case-preserving: although existing files can be opened using any case,
the exact case used to create the file is preserved and available for
programs to query. It is not allowed for two files in the same directory
to differ only by case.</p>
<p>Usually file systems on macOS are case-insensitive. It is possible to
make macOS file systems case-sensitive but that is not the default.</p>
<p>The <code>--vfs-case-insensitive</code> VFS flag controls how rclone
handles these two cases. If its value is "false", rclone passes file
names to the remote as-is. If the flag is "true" (or appears without a
value on the command line), rclone may perform a "fixup" as explained
below.</p>
<p>The user may specify a file name to open/delete/rename/etc with a
case different than what is stored on the remote. If an argument refers
to an existing file with exactly the same name, then the case of the
existing file on the disk will be used. However, if a file name with
exactly the same name is not found but a name differing only by case
exists, rclone will transparently fixup the name. This fixup happens
only when an existing file is requested. Case sensitivity of file names
created anew by rclone is controlled by the underlying remote.</p>
<p>Note that case sensitivity of the operating system running rclone
(the target) may differ from case sensitivity of a file system presented
by rclone (the source). The flag controls whether "fixup" is performed
to satisfy the target.</p>
<p>If the flag is not provided on the command line, then its default
value depends on the operating system where rclone runs: "true" on
Windows and macOS, "false" otherwise. If the flag is provided without a
value, then it is "true".</p>
<p>The <code>--no-unicode-normalization</code> flag controls whether a
similar "fixup" is performed for filenames that differ but are <a
href="https://en.wikipedia.org/wiki/Unicode_equivalence">canonically
equivalent</a> with respect to unicode. Unicode normalization can be
particularly helpful for users of macOS, which prefers form NFD instead
of the NFC used by most other platforms. It is therefore highly
recommended to keep the default of <code>false</code> on macOS, to avoid
encoding compatibility issues.</p>
<p>In the (probably unlikely) event that a directory has multiple
duplicate filenames after applying case and unicode normalization, the
<code>--vfs-block-norm-dupes</code> flag allows hiding these duplicates.
This comes with a performance tradeoff, as rclone will have to scan the
entire directory for duplicates when listing a directory. For this
reason, it is recommended to leave this disabled if not needed. However,
macOS users may wish to consider using it, as otherwise, if a remote
directory contains both NFC and NFD versions of the same filename, an
odd situation will occur: both versions of the file will be visible in
the mount, and both will appear to be editable, however, editing either
version will actually result in only the NFD version getting edited
under the hood. <code>--vfs-block- norm-dupes</code> prevents this
confusion by detecting this scenario, hiding the duplicates, and logging
an error, similar to how this is handled in
<code>rclone sync</code>.</p>
<h2 id="vfs-disk-options-1">VFS Disk Options</h2>
<p>This flag allows you to manually set the statistics about the filing
system. It can be useful when those statistics cannot be read correctly
automatically.</p>
<pre class="text"><code>    --vfs-disk-space-total-size    Manually set the total disk space size (example: 256G, default: -1)</code></pre>
<h2 id="alternate-report-of-used-bytes-1">Alternate report of used
bytes</h2>
<p>Some backends, most notably S3, do not report the amount of bytes
used. If you need this information to be available when running
<code>df</code> on the filesystem, then pass the flag
<code>--vfs-used-is-size</code> to rclone. With this flag set, instead
of relying on the backend to report this information, rclone will scan
the whole remote similar to <code>rclone size</code> and compute the
total used space itself.</p>
<p><strong>WARNING</strong>: Contrary to <code>rclone size</code>, this
flag ignores filters so that the result is accurate. However, this is
very inefficient and may cost lots of API calls resulting in extra
charges. Use it as a last resort and only with caching.</p>
<h2 id="vfs-metadata-1">VFS Metadata</h2>
<p>If you use the <code>--vfs-metadata-extension</code> flag you can get
the VFS to expose files which contain the <a
href="https://rclone.org/docs/#metadata">metadata</a> as a JSON blob.
These files will not appear in the directory listing, but can be
<code>stat</code>-ed and opened and once they have been they
<strong>will</strong> appear in directory listings until the directory
cache expires.</p>
<p>Note that some backends won't create metadata unless you pass in the
<code>--metadata</code> flag.</p>
<p>For example, using <code>rclone mount</code> with
<code>--metadata --vfs-metadata-extension .metadata</code> we get</p>
<pre class="console"><code>$ ls -l /mnt/

<h1 id="rclone-obscure">rclone obscure</h1>
<p>Obscure password for use in the rclone config file.</p>
<h2 id="synopsis-63">Synopsis</h2>
<p>In the rclone config file, human-readable passwords are obscured.
Obscuring them is done by encrypting them and writing them out in
base64. This is <strong>not</strong> a secure way of encrypting these
passwords as rclone can decrypt them - it is to prevent "eyedropping" -
namely someone seeing a password in the rclone config file by
accident.</p>
<p>Many equally important things (like access tokens) are not obscured
in the config file. However it is very hard to shoulder surf a 64
character hex token.</p>
<p>This command can also accept a password through STDIN instead of an
argument by passing a hyphen as an argument. This will use the first
line of STDIN as the password not including the trailing newline.</p>
<pre class="console"><code>echo &quot;secretpassword&quot; | rclone obscure -</code></pre>
<p>If there is no data on STDIN to read, rclone obscure will default to
obfuscating the hyphen itself.</p>
<p>If you want to encrypt the config file then please use config file
encryption - see <a

more info.</p>

<p>Run a command against a running rclone.</p>
<h2 id="synopsis-64">Synopsis</h2>
<p>This runs a command against a running rclone. Use the
<code>--url</code> flag to specify an non default URL to connect on.
This can be either a ":port" which is taken to mean <a
href="http://localhost:port" class="uri">http://localhost:port</a> or a
"host:port" which is taken to mean <a href="http://host:port"
class="uri">http://host:port</a>.</p>
<p>A username and password can be passed in with <code>--user</code> and
<code>--pass</code>.</p>
<p>Note that <code>--rc-addr</code>, <code>--rc-user</code>,
<code>--rc-pass</code> will be read also for <code>--url</code>,
<code>--user</code>, <code>--pass</code>.</p>
<p>The <code>--unix-socket</code> flag can be used to connect over a
unix socket like this</p>
<div class="sourceCode" id="cb415"><pre

<p>Arguments should be passed in as parameter=value.</p>
<p>The result will be returned as a JSON object by default.</p>
<p>The <code>--json</code> parameter can be used to pass in a JSON blob
as an input instead of key=value arguments. This is the only way of
passing in more complicated values.</p>
<p>The <code>-o</code>/<code>--opt</code> option can be used to set a
key "opt" with key, value options in the form <code>-o key=value</code>
or <code>-o key</code>. It can be repeated as many times as required.
This is useful for rc commands which take the "opt" parameter which by
convention is a dictionary of strings.</p>
<pre class="text"><code>-o key=value -o key2</code></pre>

<h1 id="rclone-rcat">rclone rcat</h1>
<p>Copies standard input to file on remote.</p>
<h2 id="synopsis-65">Synopsis</h2>
<p>Reads from standard input (stdin) and copies it to a single remote
file.</p>
<pre class="console"><code>echo &quot;hello world&quot; | rclone rcat remote:path/to/file
ffmpeg - | rclone rcat remote:path/to/file</code></pre>
<p>If the remote file already exists, it will be overwritten.</p>
<p>rcat will try to upload small files in a single request, which is
usually more efficient than the streaming/chunked upload endpoints,
which use multiple requests. Exact behaviour depends on the remote. What
is considered a small file may be set through
<code>--streaming-upload-cutoff</code>. Uploading only starts after the
cutoff is reached or if the file ends before that. The data must fit
into RAM. The cutoff needs to be small enough to adhere the limits of
your remote, please see there. Generally speaking, setting this cutoff
too high will decrease your performance.</p>
<p>Use the <code>--size</code> flag to preallocate the file in advance
at the remote end and actually stream it, even if remote backend doesn't
support streaming.</p>
<p><code>--size</code> should be the exact size of the input stream in
bytes. If the size of the stream is different in length to the
<code>--size</code> passed in then the transfer will likely fail.</p>
<p>Note that the upload cannot be retried because the data is not
stored. If the backend supports multipart uploading then individual
chunks can be retried. If you need to transfer a lot of data, you may be
better off caching it locally and then <code>rclone move</code> it to
the destination which can use retries.</p>

<p>Run rclone listening to remote control commands only.</p>
<h2 id="synopsis-66">Synopsis</h2>
<p>This runs rclone so that it only listens to remote control
commands.</p>
<p>This is useful if you are controlling rclone via the rc API.</p>
<p>If you pass in a path to a directory, rclone will serve that
directory for GET requests on the URL passed in. It will also open the
URL in the browser when rclone is run.</p>
<p>See the <a href="https://rclone.org/rc/">rc documentation</a> for
more info on the rc flags.</p>
<h2 id="server-options">Server options</h2>
<p>Use <code>--rc-addr</code> to specify which IP address and port the
server should listen on, eg <code>--rc-addr 1.2.3.4:8000</code> or
<code>--rc-addr :8080</code> to listen to all IPs. By default it only
listens on localhost. You can use port :0 to let the OS choose an
available port.</p>
<p>If you set <code>--rc-addr</code> to listen on a public or LAN
accessible IP address then using Authentication is advised - see the
next section for info.</p>
<p>You can use a unix socket by setting the url to
<code>unix:///path/to/socket</code> or just by using an absolute path
name.</p>
<p><code>--rc-addr</code> may be repeated to listen on multiple
IPs/ports/sockets. Socket activation, described further below, can also
be used to accomplish the same.</p>
<p><code>--rc-server-read-timeout</code> and
<code>--rc-server-write-timeout</code> can be used to control the
timeouts on the server. Note that this is the total time for a
transfer.</p>
<p><code>--rc-max-header-bytes</code> controls the maximum number of
bytes the server will accept in the HTTP header.</p>
<p><code>--rc-baseurl</code> controls the URL prefix that rclone serves
from. By default rclone will serve from the root. If you used
<code>--rc-baseurl "/rclone"</code> then rclone would serve from a URL
starting with "/rclone/". This is useful if you wish to proxy rclone
serve. Rclone automatically inserts leading and trailing "/" on
<code>--rc-baseurl</code>, so <code>--rc-baseurl "rclone"</code>,
<code>--rc-baseurl "/rclone"</code> and
<code>--rc-baseurl "/rclone/"</code> are all treated identically.</p>
<p><code>--rc-disable-zip</code> may be set to disable the zipping
download option.</p>
<h3 id="tls-ssl">TLS (SSL)</h3>
<p>By default this will serve over http. If you want you can serve over
https. You will need to supply the <code>--rc-cert</code> and
<code>--rc-key</code> flags. If you wish to do client side certificate
validation then you will need to supply <code>--rc-client-ca</code>
also.</p>
<p><code>--rc-cert</code> must be set to the path of a file containing
either a PEM encoded certificate, or a concatenation of that with the CA
certificate. <code>--rc-key</code> must be set to the path of a file
with the PEM encoded private key. If setting
<code>--rc-client-ca</code>, it should be set to the path of a file with
PEM encoded client certificate authority certificates.</p>
<p><code>--rc-min-tls-version</code> is minimum TLS version that is
acceptable. Valid values are "tls1.0", "tls1.1", "tls1.2" and "tls1.3"
(default "tls1.0").</p>
<h2 id="socket-activation">Socket activation</h2>
<p>Instead of the listening addresses specified above, rclone will
listen to all FDs passed by the service manager, if any (and ignore any
arguments passed by <code>--rc-addr</code>).</p>
<p>This allows rclone to be a socket-activated service. It can be
configured with .socket and .service unit files as described in <a
href="https://www.freedesktop.org/software/systemd/man/latest/systemd.socket.html"
class="uri">https://www.freedesktop.org/software/systemd/man/latest/systemd.socket.html</a>.</p>
<p>Socket activation can be tested ad-hoc with the
<code>systemd-socket-activate</code>command</p>
<pre class="console"><code>systemd-socket-activate -l 8000 -- rclone serve</code></pre>
<p>This will socket-activate rclone on the first connection to port 8000
over TCP.</p>
<h3 id="template">Template</h3>
<p><code>--rc-template</code> allows a user to specify a custom markup
template for HTTP and WebDAV serve functions. The server exports the
following markup to be used within the template to server pages:</p>

<h3 id="authentication">Authentication</h3>
<p>By default this will serve files without needing a login.</p>
<p>You can either use an htpasswd file which can take lots of users, or
set a single username and password with the <code>--rc-user</code> and
<code>--rc-pass</code> flags.</p>
<p>Alternatively, you can have the reverse proxy manage authentication
and use the username provided in the configured header with
<code>--user-from-header</code> (e.g.,
<code>--rc-user-from-header=x-remote-user</code>). Ensure the proxy is
trusted and headers cannot be spoofed, as misconfiguration may lead to
unauthorized access.</p>
<p>If either of the above authentication methods is not configured and
client certificates are required by the <code>--client-ca</code> flag
passed to the server, the client certificate common name will be
considered as the username.</p>
<p>Use <code>--rc-htpasswd /path/to/htpasswd</code> to provide an
htpasswd file. This is in standard apache format and supports MD5, SHA1
and BCrypt for basic authentication. Bcrypt is recommended.</p>
<p>To create an htpasswd file:</p>
<pre class="console"><code>touch htpasswd
htpasswd -B htpasswd user
htpasswd -B htpasswd anotherUser</code></pre>
<p>The password file can be updated while rclone is running.</p>
<p>Use <code>--rc-realm</code> to set the authentication realm.</p>
<p>Use <code>--rc-salt</code> to change the password hashing salt from
the default.</p>

<p>Remove empty directories under the path.</p>
<h2 id="synopsis-67">Synopsis</h2>
<p>This recursively removes any empty directories (including directories
that only contain empty directories), that it finds under the path. The
root path itself will also be removed if it is empty, unless you supply
the <code>--leave-root</code> flag.</p>
<p>Use command <a
href="https://rclone.org/commands/rclone_rmdir/">rmdir</a> to delete
just the empty directory given by path, not recurse.</p>
<p>This is useful for tidying up remotes that rclone has left a lot of
empty directories in. For example the <a
href="https://rclone.org/commands/rclone_delete/">delete</a> command
will delete files but leave the directory structure (unless used with
option <code>--rmdirs</code>).</p>
<p>This will delete <code>--checkers</code> directories concurrently so
if you have thousands of empty directories consider increasing this
number.</p>
<p>To delete a path and any objects in it, use the <a

<h1 id="rclone-selfupdate">rclone selfupdate</h1>
<p>Update the rclone binary.</p>
<h2 id="synopsis-68">Synopsis</h2>
<p>This command downloads the latest release of rclone and replaces the
currently running binary. The download is verified with a hashsum and
cryptographically signed signature; see <a
href="https://rclone.org/release_signing/">the release signing docs</a>
for details.</p>
<p>If used without flags (or with implied <code>--stable</code> flag),
this command will install the latest stable release. However, some
issues may be fixed (or features added) only in the latest beta release.
In such cases you should run the command with the <code>--beta</code>
flag, i.e. <code>rclone selfupdate --beta</code>. You can check in
advance what version would be installed by adding the
<code>--check</code> flag, then repeat the command without it when you
are satisfied.</p>
<p>Sometimes the rclone team may recommend you a concrete beta or stable
rclone release to troubleshoot your issue or add a bleeding edge
feature. The <code>--version VER</code> flag, if given, will update to
the concrete version instead of the latest one. If you omit micro
version from <code>VER</code> (for example <code>1.53</code>), the
latest matching micro version will be used.</p>
<p>Upon successful update rclone will print a message that contains a
previous version number. You will need it if you later decide to revert
your update for some reason. Then you'll have to note the previous
version and run the following command:
<code>rclone selfupdate [--beta] OLDVER</code>. If the old version
contains only dots and digits (for example <code>v1.54.0</code>) then
it's a stable release so you won't need the <code>--beta</code> flag.
Beta releases have an additional information similar to
<code>v1.54.0-beta.5111.06f1c0c61</code>. (if you are a developer and
use a locally built rclone, the version number will end with
<code>-DEV</code>, you will have to rebuild it as it obviously can't be
distributed).</p>
<p>If you previously installed rclone via a package manager, the package
may include local documentation or configure services. You may wish to
update with the flag <code>--package deb</code> or
<code>--package rpm</code> (whichever is correct for your OS) to update
these too. This command with the default <code>--package zip</code> will
update only the rclone executable so the local manual may become
inaccurate after it.</p>
<p>The <a href="https://rclone.org/commands/rclone_mount/">rclone
mount</a> command may or may not support extended FUSE options depending
on the build and OS. <code>selfupdate</code> will refuse to update if
the capability would be discarded.</p>
<p>Note: Windows forbids deletion of a currently running executable so
this command will rename the old executable to 'rclone.old.exe' upon
success.</p>
<p>Please note that this command was not available before rclone version
1.55. If it fails for you with the message
<code>unknown command "selfupdate"</code> then you will need to update
manually following the <a href="https://rclone.org/install/">install
documentation</a>.</p>

<h1 id="rclone-serve-dlna">rclone serve dlna</h1>
<p>Serve remote:path over DLNA</p>
<h2 id="synopsis-70">Synopsis</h2>
<p>Run a DLNA media server for media stored in an rclone remote. Many
devices, such as the Xbox and PlayStation, can automatically discover
this server in the LAN and play audio/video from it. VLC is also
supported. Service discovery uses UDP multicast packets (SSDP) and will
thus only work on LANs.</p>
<p>Rclone will list all files present in the remote, without filtering
based on media formats or file extensions. Additionally, there is no
media transcoding support. This means that some players might show files
that they are not able to play back correctly.</p>
<p>Rclone will add external subtitle files (.srt) to videos if they have
the same filename as the video file itself (except the extension),
either in the same directory as the video, or in a "Subs"
subdirectory.</p>
<h2 id="server-options-1">Server options</h2>
<p>Use <code>--addr</code> to specify which IP address and port the
server should listen on, e.g. <code>--addr 1.2.3.4:8000</code> or
<code>--addr :8080</code> to listen to all IPs.</p>
<p>Use <code>--name</code> to choose the friendly server name, which is
by default "rclone (hostname)".</p>
<p>Use <code>--log-trace</code> in conjunction with <code>-vv</code> to
enable additional debug logging of all UPNP traffic.</p>
<h2 id="vfs---virtual-file-system-2">VFS - Virtual File System</h2>
<p>This command uses the VFS layer. This adapts the cloud storage
objects that rclone uses into something which looks much more like a
disk filing system.</p>
<p>Cloud storage objects have lots of properties which aren't like disk
files - you can't extend them or write to the middle of them, so the VFS
layer has to deal with that. Because there is no one right way of doing
this there are various options explained below.</p>
<p>The VFS layer also implements a directory cache - this caches info
about files and directories (but not the data) in memory.</p>
<h2 id="vfs-directory-cache-2">VFS Directory Cache</h2>
<p>Using the <code>--dir-cache-time</code> flag, you can control how
long a directory should be considered up to date and not refreshed from
the backend. Changes made through the VFS will appear immediately or
invalidate the cache.</p>
<pre class="text"><code>    --dir-cache-time duration   Time to cache directory entries for (default 5m0s)
    --poll-interval duration    Time to wait between polling for changes. Must be smaller than dir-cache-time. Only on supported remotes. Set to 0 to disable (default 1m0s)</code></pre>
<p>However, changes made directly on the cloud storage by the web
interface or a different copy of rclone will only be picked up once the
directory cache expires if the backend configured does not support
polling for changes. If the backend supports polling, changes will be
picked up within the polling interval.</p>
<p>You can send a <code>SIGHUP</code> signal to rclone for it to flush
all directory caches, regardless of how old they are. Assuming only one
rclone instance is running, you can reset the cache like this:</p>
<pre class="console"><code>kill -SIGHUP $(pidof rclone)</code></pre>
<p>If you configure rclone with a <a href="/rc">remote control</a> then
you can use rclone rc to flush the whole directory cache:</p>
<pre class="console"><code>rclone rc vfs/forget</code></pre>
<p>Or individual files or directories:</p>
<pre class="console"><code>rclone rc vfs/forget file=path/to/file dir=path/to/dir</code></pre>
<h2 id="vfs-file-buffering-2">VFS File Buffering</h2>
<p>The <code>--buffer-size</code> flag determines the amount of memory,
that will be used to buffer data in advance.</p>
<p>Each open file will try to keep the specified amount of data in
memory at all times. The buffered data is bound to one open file and
won't be shared.</p>
<p>This flag is a upper limit for the used memory per open file. The
buffer will only use memory for data that is downloaded but not not yet
read. If the buffer is empty, only a small amount of memory will be
used.</p>
<p>The maximum memory used by rclone for buffering can be up to
<code>--buffer-size * open files</code>.</p>
<h2 id="vfs-file-caching-2">VFS File Caching</h2>
<p>These flags control the VFS file caching options. File caching is
necessary to make the VFS layer appear compatible with a normal file
system. It can be disabled at the cost of some compatibility.</p>
<p>For example you'll need to enable VFS caching if you want to read and
write simultaneously to a file. See below for more details.</p>
<p>Note that the VFS cache is separate from the cache backend and you
may find that you need one or the other or both.</p>
<pre class="text"><code>    --cache-dir string                     Directory rclone will use for caching.
    --vfs-cache-mode CacheMode             Cache mode off|minimal|writes|full (default off)
    --vfs-cache-max-age duration           Max time since last access of objects in the cache (default 1h0m0s)
    --vfs-cache-max-size SizeSuffix        Max total size of objects in the cache (default off)
    --vfs-cache-min-free-space SizeSuffix  Target minimum free space on the disk containing the cache (default off)
    --vfs-cache-poll-interval duration     Interval to poll the cache for stale objects (default 1m0s)
    --vfs-write-back duration              Time to writeback files after last use when using cache (default 5s)</code></pre>
<p>If run with <code>-vv</code> rclone will print the location of the
file cache. The files are stored in the user cache file area which is OS
dependent but can be controlled with <code>--cache-dir</code> or setting
the appropriate environment variable.</p>
<p>The cache has 4 different modes selected by
<code>--vfs-cache-mode</code>. The higher the cache mode the more
compatible rclone becomes at the cost of using disk space.</p>
<p>Note that files are written back to the remote only when they are
closed and if they haven't been accessed for
<code>--vfs-write-back</code> seconds. If rclone is quit or dies with
files that haven't been uploaded, these will be uploaded next time
rclone is run with the same flags.</p>
<p>If using <code>--vfs-cache-max-size</code> or
<code>--vfs-cache-min-free-space</code> note that the cache may exceed
these quotas for two reasons. Firstly because it is only checked every
<code>--vfs-cache-poll-interval</code>. Secondly because open files
cannot be evicted from the cache. When <code>--vfs-cache-max-size</code>
or <code>--vfs-cache-min-free-space</code> is exceeded, rclone will
attempt to evict the least accessed files from the cache first. rclone
will start with files that haven't been accessed for the longest. This
cache flushing strategy is efficient and more relevant files are likely
to remain cached.</p>
<p>The <code>--vfs-cache-max-age</code> will evict files from the cache
after the set time since last access has passed. The default value of 1
hour will start evicting files from cache that haven't been accessed for
1 hour. When a cached file is accessed the 1 hour timer is reset to 0
and will wait for 1 more hour before evicting. Specify the time with
standard notation, s, m, h, d, w .</p>
<p>You <strong>should not</strong> run two copies of rclone using the
same VFS cache with the same or overlapping remotes if using
<code>--vfs-cache-mode &gt; off</code>. This can potentially cause data
corruption if you do. You can work around this by giving each rclone its
own cache hierarchy with <code>--cache-dir</code>. You don't need to
worry about this if the remotes in use don't overlap.</p>
<h3 id="vfs-cache-mode-off-2">--vfs-cache-mode off</h3>
<p>In this mode (the default) the cache will read directly from the
remote and write directly to the remote without caching anything on
disk.</p>
<p>This will mean some operations are not possible</p>
<ul>
<li>Files can't be opened for both read AND write</li>
<li>Files opened for write can't be seeked</li>
<li>Existing files opened for write must have O_TRUNC set</li>
<li>Files open for read with O_TRUNC will be opened write only</li>
<li>Files open for write only will behave as if O_TRUNC was
supplied</li>
<li>Open modes O_APPEND, O_TRUNC are ignored</li>
<li>If an upload fails it can't be retried</li>
</ul>
<h3 id="vfs-cache-mode-minimal-2">--vfs-cache-mode minimal</h3>
<p>This is very similar to "off" except that files opened for read AND
write will be buffered to disk. This means that files opened for write
will be a lot more compatible, but uses the minimal disk space.</p>
<p>These operations are not possible</p>
<ul>
<li>Files opened for write only can't be seeked</li>
<li>Existing files opened for write must have O_TRUNC set</li>
<li>Files opened for write only will ignore O_APPEND, O_TRUNC</li>
<li>If an upload fails it can't be retried</li>
</ul>
<h3 id="vfs-cache-mode-writes-2">--vfs-cache-mode writes</h3>
<p>In this mode files opened for read only are still read directly from
the remote, write only and read/write files are buffered to disk
first.</p>
<p>This mode should support all normal file system operations.</p>
<p>If an upload fails it will be retried at exponentially increasing
intervals up to 1 minute.</p>
<h3 id="vfs-cache-mode-full-2">--vfs-cache-mode full</h3>
<p>In this mode all reads and writes are buffered to and from disk. When
data is read from the remote this is buffered to disk as well.</p>
<p>In this mode the files in the cache will be sparse files and rclone
will keep track of which bits of the files it has downloaded.</p>
<p>So if an application only reads the starts of each file, then rclone
will only buffer the start of the file. These files will appear to be
their full size in the cache, but they will be sparse files with only
the data that has been downloaded present in them.</p>
<p>This mode should support all normal file system operations and is
otherwise identical to <code>--vfs-cache-mode</code> writes.</p>
<p>When reading a file rclone will read <code>--buffer-size</code> plus
<code>--vfs-read-ahead</code> bytes ahead. The
<code>--buffer-size</code> is buffered in memory whereas the
<code>--vfs-read-ahead</code> is buffered on disk.</p>
<p>When using this mode it is recommended that
<code>--buffer-size</code> is not set too large and
<code>--vfs-read-ahead</code> is set large if required.</p>
<p><strong>IMPORTANT</strong> not all file systems support sparse files.
In particular FAT/exFAT do not. Rclone will perform very badly if the
cache directory is on a filesystem which doesn't support sparse files
and it will log an ERROR message if one is detected.</p>
<h3 id="fingerprinting-2">Fingerprinting</h3>
<p>Various parts of the VFS use fingerprinting to see if a local file
copy has changed relative to a remote file. Fingerprints are made
from:</p>
<ul>
<li>size</li>
<li>modification time</li>
<li>hash</li>
</ul>
<p>where available on an object.</p>
<p>On some backends some of these attributes are slow to read (they take
an extra API call per object, or extra work per object).</p>
<p>For example <code>hash</code> is slow with the <code>local</code> and
<code>sftp</code> backends as they have to read the entire file and hash
it, and <code>modtime</code> is slow with the <code>s3</code>,
<code>swift</code>, <code>ftp</code> and <code>qinqstor</code> backends
because they need to do an extra API call to fetch it.</p>
<p>If you use the <code>--vfs-fast-fingerprint</code> flag then rclone
will not include the slow operations in the fingerprint. This makes the
fingerprinting less accurate but much faster and will improve the
opening time of cached files.</p>
<p>If you are running a vfs cache over <code>local</code>,
<code>s3</code> or <code>swift</code> backends then using this flag is
recommended.</p>
<p>Note that if you change the value of this flag, the fingerprints of
the files in the cache may be invalidated and the files will need to be
downloaded again.</p>
<h2 id="vfs-chunked-reading-2">VFS Chunked Reading</h2>
<p>When rclone reads files from a remote it reads them in chunks. This
means that rather than requesting the whole file rclone reads the chunk
specified. This can reduce the used download quota for some remotes by
requesting only chunks from the remote that are actually read, at the
cost of an increased number of requests.</p>
<p>These flags control the chunking:</p>
<pre class="text"><code>    --vfs-read-chunk-size SizeSuffix        Read the source objects in chunks (default 128M)
    --vfs-read-chunk-size-limit SizeSuffix  Max chunk doubling size (default off)
    --vfs-read-chunk-streams int            The number of parallel streams to read at once</code></pre>
<p>The chunking behaves differently depending on the
<code>--vfs-read-chunk-streams</code> parameter.</p>
<h3
id="vfs-read-chunk-streams-0-4"><code>--vfs-read-chunk-streams</code> ==
0</h3>
<p>Rclone will start reading a chunk of size
<code>--vfs-read-chunk-size</code>, and then double the size for each
read. When <code>--vfs-read-chunk-size-limit</code> is specified, and
greater than <code>--vfs-read-chunk-size</code>, the chunk size for each
open file will get doubled only until the specified value is reached. If
the value is "off", which is the default, the limit is disabled and the
chunk size will grow indefinitely.</p>
<p>With <code>--vfs-read-chunk-size 100M</code> and
<code>--vfs-read-chunk-size-limit 0</code> the following parts will be
downloaded: 0-100M, 100M-200M, 200M-300M, 300M-400M and so on. When
<code>--vfs-read-chunk-size-limit 500M</code> is specified, the result
would be 0-100M, 100M-300M, 300M-700M, 700M-1200M, 1200M-1700M and so
on.</p>
<p>Setting <code>--vfs-read-chunk-size</code> to <code>0</code> or "off"
disables chunked reading.</p>
<p>The chunks will not be buffered in memory.</p>
<h3
id="vfs-read-chunk-streams-0-5"><code>--vfs-read-chunk-streams</code>
&gt; 0</h3>
<p>Rclone reads <code>--vfs-read-chunk-streams</code> chunks of size
<code>--vfs-read-chunk-size</code> concurrently. The size for each read
will stay constant.</p>
<p>This improves performance performance massively on high latency links
or very high bandwidth links to high performance object stores.</p>
<p>Some experimentation will be needed to find the optimum values of
<code>--vfs-read-chunk-size</code> and
<code>--vfs-read-chunk-streams</code> as these will depend on the
backend in use and the latency to the backend.</p>
<p>For high performance object stores (eg AWS S3) a reasonable place to
start might be <code>--vfs-read-chunk-streams 16</code> and
<code>--vfs-read-chunk-size 4M</code>. In testing with AWS S3 the
performance scaled roughly as the <code>--vfs-read-chunk-streams</code>
setting.</p>
<p>Similar settings should work for high latency links, but depending on
the latency they may need more <code>--vfs-read-chunk-streams</code> in
order to get the throughput.</p>
<h2 id="vfs-performance-2">VFS Performance</h2>
<p>These flags may be used to enable/disable features of the VFS for
performance or other reasons. See also the <a
href="#vfs-chunked-reading">chunked reading</a> feature.</p>
<p>In particular S3 and Swift benefit hugely from the
<code>--no-modtime</code> flag (or use <code>--use-server-modtime</code>
for a slightly different effect) as each read of the modification time
takes a transaction.</p>
<pre class="text"><code>    --no-checksum     Don&#39;t compare checksums on up/download.
    --no-modtime      Don&#39;t read/write the modification time (can speed things up).
    --no-seek         Don&#39;t allow seeking in files.
    --read-only       Only allow read-only access.</code></pre>
<p>Sometimes rclone is delivered reads or writes out of order. Rather
than seeking rclone will wait a short time for the in sequence read or
write to come in. These flags only come into effect when not using an on
disk cache file.</p>
<pre class="text"><code>    --vfs-read-wait duration   Time to wait for in-sequence read before seeking (default 20ms)
    --vfs-write-wait duration  Time to wait for in-sequence write before giving error (default 1s)</code></pre>
<p>When using VFS write caching (<code>--vfs-cache-mode</code> with
value writes or full), the global flag <code>--transfers</code> can be
set to adjust the number of parallel uploads of modified files from the
cache (the related global flag <code>--checkers</code> has no effect on
the VFS).</p>
<pre class="text"><code>    --transfers int  Number of file transfers to run in parallel (default 4)</code></pre>
<h2 id="symlinks-2">Symlinks</h2>
<p>By default the VFS does not support symlinks. However this may be
enabled with either of the following flags:</p>
<pre class="text"><code>    --links      Translate symlinks to/from regular files with a &#39;.rclonelink&#39; extension.
    --vfs-links  Translate symlinks to/from regular files with a &#39;.rclonelink&#39; extension for the VFS</code></pre>
<p>As most cloud storage systems do not support symlinks directly,
rclone stores the symlink as a normal file with a special extension. So
a file which appears as a symlink <code>link-to-file.txt</code> would be
stored on cloud storage as <code>link-to-file.txt.rclonelink</code> and
the contents would be the path to the symlink destination.</p>
<p>Note that <code>--links</code> enables symlink translation globally
in rclone - this includes any backend which supports the concept (for
example the local backend). <code>--vfs-links</code> just enables it for
the VFS layer.</p>
<p>This scheme is compatible with that used by the <a
href="https://rclone.org/local/#symlinks-junction-points">local backend
with the --local-links flag</a>.</p>
<p>The <code>--vfs-links</code> flag has been designed for
<code>rclone mount</code>, <code>rclone nfsmount</code> and
<code>rclone serve nfs</code>.</p>
<p>It hasn't been tested with the other <code>rclone serve</code>
commands yet.</p>
<p>A limitation of the current implementation is that it expects the
caller to resolve sub-symlinks. For example given this directory
tree</p>
<pre class="text"><code>.
├── dir
│   └── file.txt
└── linked-dir -&gt; dir</code></pre>
<p>The VFS will correctly resolve <code>linked-dir</code> but not
<code>linked-dir/file.txt</code>. This is not a problem for the tested
commands but may be for other commands.</p>
<p><strong>Note</strong> that there is an outstanding issue with symlink
support <a href="https://github.com/rclone/rclone/issues/8245">issue
#8245</a> with duplicate files being created when symlinks are moved
into directories where there is a file of the same name (or vice
versa).</p>
<h2 id="vfs-case-sensitivity-2">VFS Case Sensitivity</h2>
<p>Linux file systems are case-sensitive: two files can differ only by
case, and the exact case must be used when opening a file.</p>
<p>File systems in modern Windows are case-insensitive but
case-preserving: although existing files can be opened using any case,
the exact case used to create the file is preserved and available for
programs to query. It is not allowed for two files in the same directory
to differ only by case.</p>
<p>Usually file systems on macOS are case-insensitive. It is possible to
make macOS file systems case-sensitive but that is not the default.</p>
<p>The <code>--vfs-case-insensitive</code> VFS flag controls how rclone
handles these two cases. If its value is "false", rclone passes file
names to the remote as-is. If the flag is "true" (or appears without a
value on the command line), rclone may perform a "fixup" as explained
below.</p>
<p>The user may specify a file name to open/delete/rename/etc with a
case different than what is stored on the remote. If an argument refers
to an existing file with exactly the same name, then the case of the
existing file on the disk will be used. However, if a file name with
exactly the same name is not found but a name differing only by case
exists, rclone will transparently fixup the name. This fixup happens
only when an existing file is requested. Case sensitivity of file names
created anew by rclone is controlled by the underlying remote.</p>
<p>Note that case sensitivity of the operating system running rclone
(the target) may differ from case sensitivity of a file system presented
by rclone (the source). The flag controls whether "fixup" is performed
to satisfy the target.</p>
<p>If the flag is not provided on the command line, then its default
value depends on the operating system where rclone runs: "true" on
Windows and macOS, "false" otherwise. If the flag is provided without a
value, then it is "true".</p>
<p>The <code>--no-unicode-normalization</code> flag controls whether a
similar "fixup" is performed for filenames that differ but are <a
href="https://en.wikipedia.org/wiki/Unicode_equivalence">canonically
equivalent</a> with respect to unicode. Unicode normalization can be
particularly helpful for users of macOS, which prefers form NFD instead
of the NFC used by most other platforms. It is therefore highly
recommended to keep the default of <code>false</code> on macOS, to avoid
encoding compatibility issues.</p>
<p>In the (probably unlikely) event that a directory has multiple
duplicate filenames after applying case and unicode normalization, the
<code>--vfs-block-norm-dupes</code> flag allows hiding these duplicates.
This comes with a performance tradeoff, as rclone will have to scan the
entire directory for duplicates when listing a directory. For this
reason, it is recommended to leave this disabled if not needed. However,
macOS users may wish to consider using it, as otherwise, if a remote
directory contains both NFC and NFD versions of the same filename, an
odd situation will occur: both versions of the file will be visible in
the mount, and both will appear to be editable, however, editing either
version will actually result in only the NFD version getting edited
under the hood. <code>--vfs-block- norm-dupes</code> prevents this
confusion by detecting this scenario, hiding the duplicates, and logging
an error, similar to how this is handled in
<code>rclone sync</code>.</p>
<h2 id="vfs-disk-options-2">VFS Disk Options</h2>
<p>This flag allows you to manually set the statistics about the filing
system. It can be useful when those statistics cannot be read correctly
automatically.</p>
<pre class="text"><code>    --vfs-disk-space-total-size    Manually set the total disk space size (example: 256G, default: -1)</code></pre>
<h2 id="alternate-report-of-used-bytes-2">Alternate report of used
bytes</h2>
<p>Some backends, most notably S3, do not report the amount of bytes
used. If you need this information to be available when running
<code>df</code> on the filesystem, then pass the flag
<code>--vfs-used-is-size</code> to rclone. With this flag set, instead
of relying on the backend to report this information, rclone will scan
the whole remote similar to <code>rclone size</code> and compute the
total used space itself.</p>
<p><strong>WARNING</strong>: Contrary to <code>rclone size</code>, this
flag ignores filters so that the result is accurate. However, this is
very inefficient and may cost lots of API calls resulting in extra
charges. Use it as a last resort and only with caching.</p>
<h2 id="vfs-metadata-2">VFS Metadata</h2>
<p>If you use the <code>--vfs-metadata-extension</code> flag you can get
the VFS to expose files which contain the <a
href="https://rclone.org/docs/#metadata">metadata</a> as a JSON blob.
These files will not appear in the directory listing, but can be
<code>stat</code>-ed and opened and once they have been they
<strong>will</strong> appear in directory listings until the directory
cache expires.</p>
<p>Note that some backends won't create metadata unless you pass in the
<code>--metadata</code> flag.</p>
<p>For example, using <code>rclone mount</code> with
<code>--metadata --vfs-metadata-extension .metadata</code> we get</p>
<pre class="console"><code>$ ls -l /mnt/

<h1 id="rclone-serve-docker">rclone serve docker</h1>
<p>Serve any remote on docker's volume plugin API.</p>
<h2 id="synopsis-71">Synopsis</h2>
<p>This command implements the Docker volume plugin API allowing docker
to use rclone as a data storage mechanism for various cloud providers.
rclone provides <a href="/docker">docker volume plugin</a> based on
it.</p>
<p>To create a docker plugin, one must create a Unix or TCP socket that
Docker will look for when you use the plugin and then it listens for
commands from docker daemon and runs the corresponding code when
necessary. Docker plugins can run as a managed plugin under control of
the docker daemon or as an independent native service. For testing, you
can just run it directly from the command line, for example:</p>
<pre class="console"><code>sudo rclone serve docker --base-dir /tmp/rclone-volumes --socket-addr localhost:8787 -vv</code></pre>
<p>Running <code>rclone serve docker</code> will create the said socket,
listening for commands from Docker to create the necessary Volumes.
Normally you need not give the <code>--socket-addr</code> flag. The API
will listen on the unix domain socket at
<code>/run/docker/plugins/rclone.sock</code>. In the example above
rclone will create a TCP socket and a small file
<code>/etc/docker/plugins/rclone.spec</code> containing the socket
address. We use <code>sudo</code> because both paths are writeable only
by the root user.</p>
<p>If you later decide to change listening socket, the docker daemon
must be restarted to reconnect to
<code>/run/docker/plugins/rclone.sock</code> or parse new
<code>/etc/docker/plugins/rclone.spec</code>. Until you restart, any
volume related docker commands will timeout trying to access the old
socket. Running directly is supported on <strong>Linux only</strong>,
not on Windows or MacOS. This is not a problem with managed plugin mode
described in details in the <a href="https://rclone.org/docker">full
documentation</a>.</p>
<p>The command will create volume mounts under the path given by
<code>--base-dir</code> (by default
<code>/var/lib/docker-volumes/rclone</code> available only to root) and
maintain the JSON formatted file <code>docker-plugin.state</code> in the
rclone cache directory with book-keeping records of created and mounted
volumes.</p>
<p>All mount and VFS options are submitted by the docker daemon via API,
but you can also provide defaults on the command line as well as set
path to the config file and cache directory or adjust logging
verbosity.</p>
<h2 id="vfs---virtual-file-system-3">VFS - Virtual File System</h2>
<p>This command uses the VFS layer. This adapts the cloud storage
objects that rclone uses into something which looks much more like a
disk filing system.</p>
<p>Cloud storage objects have lots of properties which aren't like disk
files - you can't extend them or write to the middle of them, so the VFS
layer has to deal with that. Because there is no one right way of doing
this there are various options explained below.</p>
<p>The VFS layer also implements a directory cache - this caches info
about files and directories (but not the data) in memory.</p>
<h2 id="vfs-directory-cache-3">VFS Directory Cache</h2>
<p>Using the <code>--dir-cache-time</code> flag, you can control how
long a directory should be considered up to date and not refreshed from
the backend. Changes made through the VFS will appear immediately or
invalidate the cache.</p>
<pre class="text"><code>    --dir-cache-time duration   Time to cache directory entries for (default 5m0s)
    --poll-interval duration    Time to wait between polling for changes. Must be smaller than dir-cache-time. Only on supported remotes. Set to 0 to disable (default 1m0s)</code></pre>
<p>However, changes made directly on the cloud storage by the web
interface or a different copy of rclone will only be picked up once the
directory cache expires if the backend configured does not support
polling for changes. If the backend supports polling, changes will be
picked up within the polling interval.</p>
<p>You can send a <code>SIGHUP</code> signal to rclone for it to flush
all directory caches, regardless of how old they are. Assuming only one
rclone instance is running, you can reset the cache like this:</p>
<pre class="console"><code>kill -SIGHUP $(pidof rclone)</code></pre>
<p>If you configure rclone with a <a href="/rc">remote control</a> then
you can use rclone rc to flush the whole directory cache:</p>
<pre class="console"><code>rclone rc vfs/forget</code></pre>
<p>Or individual files or directories:</p>
<pre class="console"><code>rclone rc vfs/forget file=path/to/file dir=path/to/dir</code></pre>
<h2 id="vfs-file-buffering-3">VFS File Buffering</h2>
<p>The <code>--buffer-size</code> flag determines the amount of memory,
that will be used to buffer data in advance.</p>
<p>Each open file will try to keep the specified amount of data in
memory at all times. The buffered data is bound to one open file and
won't be shared.</p>
<p>This flag is a upper limit for the used memory per open file. The
buffer will only use memory for data that is downloaded but not not yet
read. If the buffer is empty, only a small amount of memory will be
used.</p>
<p>The maximum memory used by rclone for buffering can be up to
<code>--buffer-size * open files</code>.</p>
<h2 id="vfs-file-caching-3">VFS File Caching</h2>
<p>These flags control the VFS file caching options. File caching is
necessary to make the VFS layer appear compatible with a normal file
system. It can be disabled at the cost of some compatibility.</p>
<p>For example you'll need to enable VFS caching if you want to read and
write simultaneously to a file. See below for more details.</p>
<p>Note that the VFS cache is separate from the cache backend and you
may find that you need one or the other or both.</p>
<pre class="text"><code>    --cache-dir string                     Directory rclone will use for caching.
    --vfs-cache-mode CacheMode             Cache mode off|minimal|writes|full (default off)
    --vfs-cache-max-age duration           Max time since last access of objects in the cache (default 1h0m0s)
    --vfs-cache-max-size SizeSuffix        Max total size of objects in the cache (default off)
    --vfs-cache-min-free-space SizeSuffix  Target minimum free space on the disk containing the cache (default off)
    --vfs-cache-poll-interval duration     Interval to poll the cache for stale objects (default 1m0s)
    --vfs-write-back duration              Time to writeback files after last use when using cache (default 5s)</code></pre>
<p>If run with <code>-vv</code> rclone will print the location of the
file cache. The files are stored in the user cache file area which is OS
dependent but can be controlled with <code>--cache-dir</code> or setting
the appropriate environment variable.</p>
<p>The cache has 4 different modes selected by
<code>--vfs-cache-mode</code>. The higher the cache mode the more
compatible rclone becomes at the cost of using disk space.</p>
<p>Note that files are written back to the remote only when they are
closed and if they haven't been accessed for
<code>--vfs-write-back</code> seconds. If rclone is quit or dies with
files that haven't been uploaded, these will be uploaded next time
rclone is run with the same flags.</p>
<p>If using <code>--vfs-cache-max-size</code> or
<code>--vfs-cache-min-free-space</code> note that the cache may exceed
these quotas for two reasons. Firstly because it is only checked every
<code>--vfs-cache-poll-interval</code>. Secondly because open files
cannot be evicted from the cache. When <code>--vfs-cache-max-size</code>
or <code>--vfs-cache-min-free-space</code> is exceeded, rclone will
attempt to evict the least accessed files from the cache first. rclone
will start with files that haven't been accessed for the longest. This
cache flushing strategy is efficient and more relevant files are likely
to remain cached.</p>
<p>The <code>--vfs-cache-max-age</code> will evict files from the cache
after the set time since last access has passed. The default value of 1
hour will start evicting files from cache that haven't been accessed for
1 hour. When a cached file is accessed the 1 hour timer is reset to 0
and will wait for 1 more hour before evicting. Specify the time with
standard notation, s, m, h, d, w .</p>
<p>You <strong>should not</strong> run two copies of rclone using the
same VFS cache with the same or overlapping remotes if using
<code>--vfs-cache-mode &gt; off</code>. This can potentially cause data
corruption if you do. You can work around this by giving each rclone its
own cache hierarchy with <code>--cache-dir</code>. You don't need to
worry about this if the remotes in use don't overlap.</p>
<h3 id="vfs-cache-mode-off-3">--vfs-cache-mode off</h3>
<p>In this mode (the default) the cache will read directly from the
remote and write directly to the remote without caching anything on
disk.</p>
<p>This will mean some operations are not possible</p>
<ul>
<li>Files can't be opened for both read AND write</li>
<li>Files opened for write can't be seeked</li>
<li>Existing files opened for write must have O_TRUNC set</li>
<li>Files open for read with O_TRUNC will be opened write only</li>
<li>Files open for write only will behave as if O_TRUNC was
supplied</li>
<li>Open modes O_APPEND, O_TRUNC are ignored</li>
<li>If an upload fails it can't be retried</li>
</ul>
<h3 id="vfs-cache-mode-minimal-3">--vfs-cache-mode minimal</h3>
<p>This is very similar to "off" except that files opened for read AND
write will be buffered to disk. This means that files opened for write
will be a lot more compatible, but uses the minimal disk space.</p>
<p>These operations are not possible</p>
<ul>
<li>Files opened for write only can't be seeked</li>
<li>Existing files opened for write must have O_TRUNC set</li>
<li>Files opened for write only will ignore O_APPEND, O_TRUNC</li>
<li>If an upload fails it can't be retried</li>
</ul>
<h3 id="vfs-cache-mode-writes-3">--vfs-cache-mode writes</h3>
<p>In this mode files opened for read only are still read directly from
the remote, write only and read/write files are buffered to disk
first.</p>
<p>This mode should support all normal file system operations.</p>
<p>If an upload fails it will be retried at exponentially increasing
intervals up to 1 minute.</p>
<h3 id="vfs-cache-mode-full-3">--vfs-cache-mode full</h3>
<p>In this mode all reads and writes are buffered to and from disk. When
data is read from the remote this is buffered to disk as well.</p>
<p>In this mode the files in the cache will be sparse files and rclone
will keep track of which bits of the files it has downloaded.</p>
<p>So if an application only reads the starts of each file, then rclone
will only buffer the start of the file. These files will appear to be
their full size in the cache, but they will be sparse files with only
the data that has been downloaded present in them.</p>
<p>This mode should support all normal file system operations and is
otherwise identical to <code>--vfs-cache-mode</code> writes.</p>
<p>When reading a file rclone will read <code>--buffer-size</code> plus
<code>--vfs-read-ahead</code> bytes ahead. The
<code>--buffer-size</code> is buffered in memory whereas the
<code>--vfs-read-ahead</code> is buffered on disk.</p>
<p>When using this mode it is recommended that
<code>--buffer-size</code> is not set too large and
<code>--vfs-read-ahead</code> is set large if required.</p>
<p><strong>IMPORTANT</strong> not all file systems support sparse files.
In particular FAT/exFAT do not. Rclone will perform very badly if the
cache directory is on a filesystem which doesn't support sparse files
and it will log an ERROR message if one is detected.</p>
<h3 id="fingerprinting-3">Fingerprinting</h3>
<p>Various parts of the VFS use fingerprinting to see if a local file
copy has changed relative to a remote file. Fingerprints are made
from:</p>
<ul>
<li>size</li>
<li>modification time</li>
<li>hash</li>
</ul>
<p>where available on an object.</p>
<p>On some backends some of these attributes are slow to read (they take
an extra API call per object, or extra work per object).</p>
<p>For example <code>hash</code> is slow with the <code>local</code> and
<code>sftp</code> backends as they have to read the entire file and hash
it, and <code>modtime</code> is slow with the <code>s3</code>,
<code>swift</code>, <code>ftp</code> and <code>qinqstor</code> backends
because they need to do an extra API call to fetch it.</p>
<p>If you use the <code>--vfs-fast-fingerprint</code> flag then rclone
will not include the slow operations in the fingerprint. This makes the
fingerprinting less accurate but much faster and will improve the
opening time of cached files.</p>
<p>If you are running a vfs cache over <code>local</code>,
<code>s3</code> or <code>swift</code> backends then using this flag is
recommended.</p>
<p>Note that if you change the value of this flag, the fingerprints of
the files in the cache may be invalidated and the files will need to be
downloaded again.</p>
<h2 id="vfs-chunked-reading-3">VFS Chunked Reading</h2>
<p>When rclone reads files from a remote it reads them in chunks. This
means that rather than requesting the whole file rclone reads the chunk
specified. This can reduce the used download quota for some remotes by
requesting only chunks from the remote that are actually read, at the
cost of an increased number of requests.</p>
<p>These flags control the chunking:</p>
<pre class="text"><code>    --vfs-read-chunk-size SizeSuffix        Read the source objects in chunks (default 128M)
    --vfs-read-chunk-size-limit SizeSuffix  Max chunk doubling size (default off)
    --vfs-read-chunk-streams int            The number of parallel streams to read at once</code></pre>
<p>The chunking behaves differently depending on the
<code>--vfs-read-chunk-streams</code> parameter.</p>
<h3
id="vfs-read-chunk-streams-0-6"><code>--vfs-read-chunk-streams</code> ==
0</h3>
<p>Rclone will start reading a chunk of size
<code>--vfs-read-chunk-size</code>, and then double the size for each
read. When <code>--vfs-read-chunk-size-limit</code> is specified, and
greater than <code>--vfs-read-chunk-size</code>, the chunk size for each
open file will get doubled only until the specified value is reached. If
the value is "off", which is the default, the limit is disabled and the
chunk size will grow indefinitely.</p>
<p>With <code>--vfs-read-chunk-size 100M</code> and
<code>--vfs-read-chunk-size-limit 0</code> the following parts will be
downloaded: 0-100M, 100M-200M, 200M-300M, 300M-400M and so on. When
<code>--vfs-read-chunk-size-limit 500M</code> is specified, the result
would be 0-100M, 100M-300M, 300M-700M, 700M-1200M, 1200M-1700M and so
on.</p>
<p>Setting <code>--vfs-read-chunk-size</code> to <code>0</code> or "off"
disables chunked reading.</p>
<p>The chunks will not be buffered in memory.</p>
<h3
id="vfs-read-chunk-streams-0-7"><code>--vfs-read-chunk-streams</code>
&gt; 0</h3>
<p>Rclone reads <code>--vfs-read-chunk-streams</code> chunks of size
<code>--vfs-read-chunk-size</code> concurrently. The size for each read
will stay constant.</p>
<p>This improves performance performance massively on high latency links
or very high bandwidth links to high performance object stores.</p>
<p>Some experimentation will be needed to find the optimum values of
<code>--vfs-read-chunk-size</code> and
<code>--vfs-read-chunk-streams</code> as these will depend on the
backend in use and the latency to the backend.</p>
<p>For high performance object stores (eg AWS S3) a reasonable place to
start might be <code>--vfs-read-chunk-streams 16</code> and
<code>--vfs-read-chunk-size 4M</code>. In testing with AWS S3 the
performance scaled roughly as the <code>--vfs-read-chunk-streams</code>
setting.</p>
<p>Similar settings should work for high latency links, but depending on
the latency they may need more <code>--vfs-read-chunk-streams</code> in
order to get the throughput.</p>
<h2 id="vfs-performance-3">VFS Performance</h2>
<p>These flags may be used to enable/disable features of the VFS for
performance or other reasons. See also the <a
href="#vfs-chunked-reading">chunked reading</a> feature.</p>
<p>In particular S3 and Swift benefit hugely from the
<code>--no-modtime</code> flag (or use <code>--use-server-modtime</code>
for a slightly different effect) as each read of the modification time
takes a transaction.</p>
<pre class="text"><code>    --no-checksum     Don&#39;t compare checksums on up/download.
    --no-modtime      Don&#39;t read/write the modification time (can speed things up).
    --no-seek         Don&#39;t allow seeking in files.
    --read-only       Only allow read-only access.</code></pre>
<p>Sometimes rclone is delivered reads or writes out of order. Rather
than seeking rclone will wait a short time for the in sequence read or
write to come in. These flags only come into effect when not using an on
disk cache file.</p>
<pre class="text"><code>    --vfs-read-wait duration   Time to wait for in-sequence read before seeking (default 20ms)
    --vfs-write-wait duration  Time to wait for in-sequence write before giving error (default 1s)</code></pre>
<p>When using VFS write caching (<code>--vfs-cache-mode</code> with
value writes or full), the global flag <code>--transfers</code> can be
set to adjust the number of parallel uploads of modified files from the
cache (the related global flag <code>--checkers</code> has no effect on
the VFS).</p>
<pre class="text"><code>    --transfers int  Number of file transfers to run in parallel (default 4)</code></pre>
<h2 id="symlinks-3">Symlinks</h2>
<p>By default the VFS does not support symlinks. However this may be
enabled with either of the following flags:</p>
<pre class="text"><code>    --links      Translate symlinks to/from regular files with a &#39;.rclonelink&#39; extension.
    --vfs-links  Translate symlinks to/from regular files with a &#39;.rclonelink&#39; extension for the VFS</code></pre>
<p>As most cloud storage systems do not support symlinks directly,
rclone stores the symlink as a normal file with a special extension. So
a file which appears as a symlink <code>link-to-file.txt</code> would be
stored on cloud storage as <code>link-to-file.txt.rclonelink</code> and
the contents would be the path to the symlink destination.</p>
<p>Note that <code>--links</code> enables symlink translation globally
in rclone - this includes any backend which supports the concept (for
example the local backend). <code>--vfs-links</code> just enables it for
the VFS layer.</p>
<p>This scheme is compatible with that used by the <a
href="https://rclone.org/local/#symlinks-junction-points">local backend
with the --local-links flag</a>.</p>
<p>The <code>--vfs-links</code> flag has been designed for
<code>rclone mount</code>, <code>rclone nfsmount</code> and
<code>rclone serve nfs</code>.</p>
<p>It hasn't been tested with the other <code>rclone serve</code>
commands yet.</p>
<p>A limitation of the current implementation is that it expects the
caller to resolve sub-symlinks. For example given this directory
tree</p>
<pre class="text"><code>.
├── dir
│   └── file.txt
└── linked-dir -&gt; dir</code></pre>
<p>The VFS will correctly resolve <code>linked-dir</code> but not
<code>linked-dir/file.txt</code>. This is not a problem for the tested
commands but may be for other commands.</p>
<p><strong>Note</strong> that there is an outstanding issue with symlink
support <a href="https://github.com/rclone/rclone/issues/8245">issue
#8245</a> with duplicate files being created when symlinks are moved
into directories where there is a file of the same name (or vice
versa).</p>
<h2 id="vfs-case-sensitivity-3">VFS Case Sensitivity</h2>
<p>Linux file systems are case-sensitive: two files can differ only by
case, and the exact case must be used when opening a file.</p>
<p>File systems in modern Windows are case-insensitive but
case-preserving: although existing files can be opened using any case,
the exact case used to create the file is preserved and available for
programs to query. It is not allowed for two files in the same directory
to differ only by case.</p>
<p>Usually file systems on macOS are case-insensitive. It is possible to
make macOS file systems case-sensitive but that is not the default.</p>
<p>The <code>--vfs-case-insensitive</code> VFS flag controls how rclone
handles these two cases. If its value is "false", rclone passes file
names to the remote as-is. If the flag is "true" (or appears without a
value on the command line), rclone may perform a "fixup" as explained
below.</p>
<p>The user may specify a file name to open/delete/rename/etc with a
case different than what is stored on the remote. If an argument refers
to an existing file with exactly the same name, then the case of the
existing file on the disk will be used. However, if a file name with
exactly the same name is not found but a name differing only by case
exists, rclone will transparently fixup the name. This fixup happens
only when an existing file is requested. Case sensitivity of file names
created anew by rclone is controlled by the underlying remote.</p>
<p>Note that case sensitivity of the operating system running rclone
(the target) may differ from case sensitivity of a file system presented
by rclone (the source). The flag controls whether "fixup" is performed
to satisfy the target.</p>
<p>If the flag is not provided on the command line, then its default
value depends on the operating system where rclone runs: "true" on
Windows and macOS, "false" otherwise. If the flag is provided without a
value, then it is "true".</p>
<p>The <code>--no-unicode-normalization</code> flag controls whether a
similar "fixup" is performed for filenames that differ but are <a
href="https://en.wikipedia.org/wiki/Unicode_equivalence">canonically
equivalent</a> with respect to unicode. Unicode normalization can be
particularly helpful for users of macOS, which prefers form NFD instead
of the NFC used by most other platforms. It is therefore highly
recommended to keep the default of <code>false</code> on macOS, to avoid
encoding compatibility issues.</p>
<p>In the (probably unlikely) event that a directory has multiple
duplicate filenames after applying case and unicode normalization, the
<code>--vfs-block-norm-dupes</code> flag allows hiding these duplicates.
This comes with a performance tradeoff, as rclone will have to scan the
entire directory for duplicates when listing a directory. For this
reason, it is recommended to leave this disabled if not needed. However,
macOS users may wish to consider using it, as otherwise, if a remote
directory contains both NFC and NFD versions of the same filename, an
odd situation will occur: both versions of the file will be visible in
the mount, and both will appear to be editable, however, editing either
version will actually result in only the NFD version getting edited
under the hood. <code>--vfs-block- norm-dupes</code> prevents this
confusion by detecting this scenario, hiding the duplicates, and logging
an error, similar to how this is handled in
<code>rclone sync</code>.</p>
<h2 id="vfs-disk-options-3">VFS Disk Options</h2>
<p>This flag allows you to manually set the statistics about the filing
system. It can be useful when those statistics cannot be read correctly
automatically.</p>
<pre class="text"><code>    --vfs-disk-space-total-size    Manually set the total disk space size (example: 256G, default: -1)</code></pre>
<h2 id="alternate-report-of-used-bytes-3">Alternate report of used
bytes</h2>
<p>Some backends, most notably S3, do not report the amount of bytes
used. If you need this information to be available when running
<code>df</code> on the filesystem, then pass the flag
<code>--vfs-used-is-size</code> to rclone. With this flag set, instead
of relying on the backend to report this information, rclone will scan
the whole remote similar to <code>rclone size</code> and compute the
total used space itself.</p>
<p><strong>WARNING</strong>: Contrary to <code>rclone size</code>, this
flag ignores filters so that the result is accurate. However, this is
very inefficient and may cost lots of API calls resulting in extra
charges. Use it as a last resort and only with caching.</p>
<h2 id="vfs-metadata-3">VFS Metadata</h2>
<p>If you use the <code>--vfs-metadata-extension</code> flag you can get
the VFS to expose files which contain the <a
href="https://rclone.org/docs/#metadata">metadata</a> as a JSON blob.
These files will not appear in the directory listing, but can be
<code>stat</code>-ed and opened and once they have been they
<strong>will</strong> appear in directory listings until the directory
cache expires.</p>
<p>Note that some backends won't create metadata unless you pass in the
<code>--metadata</code> flag.</p>
<p>For example, using <code>rclone mount</code> with
<code>--metadata --vfs-metadata-extension .metadata</code> we get</p>
<pre class="console"><code>$ ls -l /mnt/

<p>Serve remote:path over FTP.</p>
<h2 id="synopsis-72">Synopsis</h2>
<p>Run a basic FTP server to serve a remote over FTP protocol. This can
be viewed with a FTP client or you can make a remote of type FTP to read
and write it.</p>
<h2 id="server-options-2">Server options</h2>
<p>Use --addr to specify which IP address and port the server should
listen on, e.g. --addr 1.2.3.4:8000 or --addr :8080 to listen to all
IPs. By default it only listens on localhost. You can use port :0 to let
the OS choose an available port.</p>
<p>If you set --addr to listen on a public or LAN accessible IP address
then using Authentication is advised - see the next section for
info.</p>
<h3 id="authentication-1">Authentication</h3>
<p>By default this will serve files without needing a login.</p>
<p>You can set a single username and password with the --user and --pass
flags.</p>
<h2 id="vfs---virtual-file-system-4">VFS - Virtual File System</h2>
<p>This command uses the VFS layer. This adapts the cloud storage
objects that rclone uses into something which looks much more like a
disk filing system.</p>
<p>Cloud storage objects have lots of properties which aren't like disk
files - you can't extend them or write to the middle of them, so the VFS
layer has to deal with that. Because there is no one right way of doing
this there are various options explained below.</p>
<p>The VFS layer also implements a directory cache - this caches info
about files and directories (but not the data) in memory.</p>
<h2 id="vfs-directory-cache-4">VFS Directory Cache</h2>
<p>Using the <code>--dir-cache-time</code> flag, you can control how
long a directory should be considered up to date and not refreshed from
the backend. Changes made through the VFS will appear immediately or
invalidate the cache.</p>
<pre class="text"><code>    --dir-cache-time duration   Time to cache directory entries for (default 5m0s)
    --poll-interval duration    Time to wait between polling for changes. Must be smaller than dir-cache-time. Only on supported remotes. Set to 0 to disable (default 1m0s)</code></pre>
<p>However, changes made directly on the cloud storage by the web
interface or a different copy of rclone will only be picked up once the
directory cache expires if the backend configured does not support
polling for changes. If the backend supports polling, changes will be
picked up within the polling interval.</p>
<p>You can send a <code>SIGHUP</code> signal to rclone for it to flush
all directory caches, regardless of how old they are. Assuming only one
rclone instance is running, you can reset the cache like this:</p>
<pre class="console"><code>kill -SIGHUP $(pidof rclone)</code></pre>
<p>If you configure rclone with a <a href="/rc">remote control</a> then
you can use rclone rc to flush the whole directory cache:</p>
<pre class="console"><code>rclone rc vfs/forget</code></pre>
<p>Or individual files or directories:</p>
<pre class="console"><code>rclone rc vfs/forget file=path/to/file dir=path/to/dir</code></pre>
<h2 id="vfs-file-buffering-4">VFS File Buffering</h2>
<p>The <code>--buffer-size</code> flag determines the amount of memory,
that will be used to buffer data in advance.</p>
<p>Each open file will try to keep the specified amount of data in
memory at all times. The buffered data is bound to one open file and
won't be shared.</p>
<p>This flag is a upper limit for the used memory per open file. The
buffer will only use memory for data that is downloaded but not not yet
read. If the buffer is empty, only a small amount of memory will be
used.</p>
<p>The maximum memory used by rclone for buffering can be up to
<code>--buffer-size * open files</code>.</p>
<h2 id="vfs-file-caching-4">VFS File Caching</h2>
<p>These flags control the VFS file caching options. File caching is
necessary to make the VFS layer appear compatible with a normal file
system. It can be disabled at the cost of some compatibility.</p>
<p>For example you'll need to enable VFS caching if you want to read and
write simultaneously to a file. See below for more details.</p>
<p>Note that the VFS cache is separate from the cache backend and you
may find that you need one or the other or both.</p>
<pre class="text"><code>    --cache-dir string                     Directory rclone will use for caching.
    --vfs-cache-mode CacheMode             Cache mode off|minimal|writes|full (default off)
    --vfs-cache-max-age duration           Max time since last access of objects in the cache (default 1h0m0s)
    --vfs-cache-max-size SizeSuffix        Max total size of objects in the cache (default off)
    --vfs-cache-min-free-space SizeSuffix  Target minimum free space on the disk containing the cache (default off)
    --vfs-cache-poll-interval duration     Interval to poll the cache for stale objects (default 1m0s)
    --vfs-write-back duration              Time to writeback files after last use when using cache (default 5s)</code></pre>
<p>If run with <code>-vv</code> rclone will print the location of the
file cache. The files are stored in the user cache file area which is OS
dependent but can be controlled with <code>--cache-dir</code> or setting
the appropriate environment variable.</p>
<p>The cache has 4 different modes selected by
<code>--vfs-cache-mode</code>. The higher the cache mode the more
compatible rclone becomes at the cost of using disk space.</p>
<p>Note that files are written back to the remote only when they are
closed and if they haven't been accessed for
<code>--vfs-write-back</code> seconds. If rclone is quit or dies with
files that haven't been uploaded, these will be uploaded next time
rclone is run with the same flags.</p>
<p>If using <code>--vfs-cache-max-size</code> or
<code>--vfs-cache-min-free-space</code> note that the cache may exceed
these quotas for two reasons. Firstly because it is only checked every
<code>--vfs-cache-poll-interval</code>. Secondly because open files
cannot be evicted from the cache. When <code>--vfs-cache-max-size</code>
or <code>--vfs-cache-min-free-space</code> is exceeded, rclone will
attempt to evict the least accessed files from the cache first. rclone
will start with files that haven't been accessed for the longest. This
cache flushing strategy is efficient and more relevant files are likely
to remain cached.</p>
<p>The <code>--vfs-cache-max-age</code> will evict files from the cache
after the set time since last access has passed. The default value of 1
hour will start evicting files from cache that haven't been accessed for
1 hour. When a cached file is accessed the 1 hour timer is reset to 0
and will wait for 1 more hour before evicting. Specify the time with
standard notation, s, m, h, d, w .</p>
<p>You <strong>should not</strong> run two copies of rclone using the
same VFS cache with the same or overlapping remotes if using
<code>--vfs-cache-mode &gt; off</code>. This can potentially cause data
corruption if you do. You can work around this by giving each rclone its
own cache hierarchy with <code>--cache-dir</code>. You don't need to
worry about this if the remotes in use don't overlap.</p>
<h3 id="vfs-cache-mode-off-4">--vfs-cache-mode off</h3>
<p>In this mode (the default) the cache will read directly from the
remote and write directly to the remote without caching anything on
disk.</p>
<p>This will mean some operations are not possible</p>
<ul>
<li>Files can't be opened for both read AND write</li>
<li>Files opened for write can't be seeked</li>
<li>Existing files opened for write must have O_TRUNC set</li>
<li>Files open for read with O_TRUNC will be opened write only</li>
<li>Files open for write only will behave as if O_TRUNC was
supplied</li>
<li>Open modes O_APPEND, O_TRUNC are ignored</li>
<li>If an upload fails it can't be retried</li>
</ul>
<h3 id="vfs-cache-mode-minimal-4">--vfs-cache-mode minimal</h3>
<p>This is very similar to "off" except that files opened for read AND
write will be buffered to disk. This means that files opened for write
will be a lot more compatible, but uses the minimal disk space.</p>
<p>These operations are not possible</p>
<ul>
<li>Files opened for write only can't be seeked</li>
<li>Existing files opened for write must have O_TRUNC set</li>
<li>Files opened for write only will ignore O_APPEND, O_TRUNC</li>
<li>If an upload fails it can't be retried</li>
</ul>
<h3 id="vfs-cache-mode-writes-4">--vfs-cache-mode writes</h3>
<p>In this mode files opened for read only are still read directly from
the remote, write only and read/write files are buffered to disk
first.</p>
<p>This mode should support all normal file system operations.</p>
<p>If an upload fails it will be retried at exponentially increasing
intervals up to 1 minute.</p>
<h3 id="vfs-cache-mode-full-4">--vfs-cache-mode full</h3>
<p>In this mode all reads and writes are buffered to and from disk. When
data is read from the remote this is buffered to disk as well.</p>
<p>In this mode the files in the cache will be sparse files and rclone
will keep track of which bits of the files it has downloaded.</p>
<p>So if an application only reads the starts of each file, then rclone
will only buffer the start of the file. These files will appear to be
their full size in the cache, but they will be sparse files with only
the data that has been downloaded present in them.</p>
<p>This mode should support all normal file system operations and is
otherwise identical to <code>--vfs-cache-mode</code> writes.</p>
<p>When reading a file rclone will read <code>--buffer-size</code> plus
<code>--vfs-read-ahead</code> bytes ahead. The
<code>--buffer-size</code> is buffered in memory whereas the
<code>--vfs-read-ahead</code> is buffered on disk.</p>
<p>When using this mode it is recommended that
<code>--buffer-size</code> is not set too large and
<code>--vfs-read-ahead</code> is set large if required.</p>
<p><strong>IMPORTANT</strong> not all file systems support sparse files.
In particular FAT/exFAT do not. Rclone will perform very badly if the
cache directory is on a filesystem which doesn't support sparse files
and it will log an ERROR message if one is detected.</p>
<h3 id="fingerprinting-4">Fingerprinting</h3>
<p>Various parts of the VFS use fingerprinting to see if a local file
copy has changed relative to a remote file. Fingerprints are made
from:</p>
<ul>
<li>size</li>
<li>modification time</li>
<li>hash</li>
</ul>
<p>where available on an object.</p>
<p>On some backends some of these attributes are slow to read (they take
an extra API call per object, or extra work per object).</p>
<p>For example <code>hash</code> is slow with the <code>local</code> and
<code>sftp</code> backends as they have to read the entire file and hash
it, and <code>modtime</code> is slow with the <code>s3</code>,
<code>swift</code>, <code>ftp</code> and <code>qinqstor</code> backends
because they need to do an extra API call to fetch it.</p>
<p>If you use the <code>--vfs-fast-fingerprint</code> flag then rclone
will not include the slow operations in the fingerprint. This makes the
fingerprinting less accurate but much faster and will improve the
opening time of cached files.</p>
<p>If you are running a vfs cache over <code>local</code>,
<code>s3</code> or <code>swift</code> backends then using this flag is
recommended.</p>
<p>Note that if you change the value of this flag, the fingerprints of
the files in the cache may be invalidated and the files will need to be
downloaded again.</p>
<h2 id="vfs-chunked-reading-4">VFS Chunked Reading</h2>
<p>When rclone reads files from a remote it reads them in chunks. This
means that rather than requesting the whole file rclone reads the chunk
specified. This can reduce the used download quota for some remotes by
requesting only chunks from the remote that are actually read, at the
cost of an increased number of requests.</p>
<p>These flags control the chunking:</p>
<pre class="text"><code>    --vfs-read-chunk-size SizeSuffix        Read the source objects in chunks (default 128M)
    --vfs-read-chunk-size-limit SizeSuffix  Max chunk doubling size (default off)
    --vfs-read-chunk-streams int            The number of parallel streams to read at once</code></pre>
<p>The chunking behaves differently depending on the
<code>--vfs-read-chunk-streams</code> parameter.</p>
<h3
id="vfs-read-chunk-streams-0-8"><code>--vfs-read-chunk-streams</code> ==
0</h3>
<p>Rclone will start reading a chunk of size
<code>--vfs-read-chunk-size</code>, and then double the size for each
read. When <code>--vfs-read-chunk-size-limit</code> is specified, and
greater than <code>--vfs-read-chunk-size</code>, the chunk size for each
open file will get doubled only until the specified value is reached. If
the value is "off", which is the default, the limit is disabled and the
chunk size will grow indefinitely.</p>
<p>With <code>--vfs-read-chunk-size 100M</code> and
<code>--vfs-read-chunk-size-limit 0</code> the following parts will be
downloaded: 0-100M, 100M-200M, 200M-300M, 300M-400M and so on. When
<code>--vfs-read-chunk-size-limit 500M</code> is specified, the result
would be 0-100M, 100M-300M, 300M-700M, 700M-1200M, 1200M-1700M and so
on.</p>
<p>Setting <code>--vfs-read-chunk-size</code> to <code>0</code> or "off"
disables chunked reading.</p>
<p>The chunks will not be buffered in memory.</p>
<h3
id="vfs-read-chunk-streams-0-9"><code>--vfs-read-chunk-streams</code>
&gt; 0</h3>
<p>Rclone reads <code>--vfs-read-chunk-streams</code> chunks of size
<code>--vfs-read-chunk-size</code> concurrently. The size for each read
will stay constant.</p>
<p>This improves performance performance massively on high latency links
or very high bandwidth links to high performance object stores.</p>
<p>Some experimentation will be needed to find the optimum values of
<code>--vfs-read-chunk-size</code> and
<code>--vfs-read-chunk-streams</code> as these will depend on the
backend in use and the latency to the backend.</p>
<p>For high performance object stores (eg AWS S3) a reasonable place to
start might be <code>--vfs-read-chunk-streams 16</code> and
<code>--vfs-read-chunk-size 4M</code>. In testing with AWS S3 the
performance scaled roughly as the <code>--vfs-read-chunk-streams</code>
setting.</p>
<p>Similar settings should work for high latency links, but depending on
the latency they may need more <code>--vfs-read-chunk-streams</code> in
order to get the throughput.</p>
<h2 id="vfs-performance-4">VFS Performance</h2>
<p>These flags may be used to enable/disable features of the VFS for
performance or other reasons. See also the <a
href="#vfs-chunked-reading">chunked reading</a> feature.</p>
<p>In particular S3 and Swift benefit hugely from the
<code>--no-modtime</code> flag (or use <code>--use-server-modtime</code>
for a slightly different effect) as each read of the modification time
takes a transaction.</p>
<pre class="text"><code>    --no-checksum     Don&#39;t compare checksums on up/download.
    --no-modtime      Don&#39;t read/write the modification time (can speed things up).
    --no-seek         Don&#39;t allow seeking in files.
    --read-only       Only allow read-only access.</code></pre>
<p>Sometimes rclone is delivered reads or writes out of order. Rather
than seeking rclone will wait a short time for the in sequence read or
write to come in. These flags only come into effect when not using an on
disk cache file.</p>
<pre class="text"><code>    --vfs-read-wait duration   Time to wait for in-sequence read before seeking (default 20ms)
    --vfs-write-wait duration  Time to wait for in-sequence write before giving error (default 1s)</code></pre>
<p>When using VFS write caching (<code>--vfs-cache-mode</code> with
value writes or full), the global flag <code>--transfers</code> can be
set to adjust the number of parallel uploads of modified files from the
cache (the related global flag <code>--checkers</code> has no effect on
the VFS).</p>
<pre class="text"><code>    --transfers int  Number of file transfers to run in parallel (default 4)</code></pre>
<h2 id="symlinks-4">Symlinks</h2>
<p>By default the VFS does not support symlinks. However this may be
enabled with either of the following flags:</p>
<pre class="text"><code>    --links      Translate symlinks to/from regular files with a &#39;.rclonelink&#39; extension.
    --vfs-links  Translate symlinks to/from regular files with a &#39;.rclonelink&#39; extension for the VFS</code></pre>
<p>As most cloud storage systems do not support symlinks directly,
rclone stores the symlink as a normal file with a special extension. So
a file which appears as a symlink <code>link-to-file.txt</code> would be
stored on cloud storage as <code>link-to-file.txt.rclonelink</code> and
the contents would be the path to the symlink destination.</p>
<p>Note that <code>--links</code> enables symlink translation globally
in rclone - this includes any backend which supports the concept (for
example the local backend). <code>--vfs-links</code> just enables it for
the VFS layer.</p>
<p>This scheme is compatible with that used by the <a
href="https://rclone.org/local/#symlinks-junction-points">local backend
with the --local-links flag</a>.</p>
<p>The <code>--vfs-links</code> flag has been designed for
<code>rclone mount</code>, <code>rclone nfsmount</code> and
<code>rclone serve nfs</code>.</p>
<p>It hasn't been tested with the other <code>rclone serve</code>
commands yet.</p>
<p>A limitation of the current implementation is that it expects the
caller to resolve sub-symlinks. For example given this directory
tree</p>
<pre class="text"><code>.
├── dir
│   └── file.txt
└── linked-dir -&gt; dir</code></pre>
<p>The VFS will correctly resolve <code>linked-dir</code> but not
<code>linked-dir/file.txt</code>. This is not a problem for the tested
commands but may be for other commands.</p>
<p><strong>Note</strong> that there is an outstanding issue with symlink
support <a href="https://github.com/rclone/rclone/issues/8245">issue
#8245</a> with duplicate files being created when symlinks are moved
into directories where there is a file of the same name (or vice
versa).</p>
<h2 id="vfs-case-sensitivity-4">VFS Case Sensitivity</h2>
<p>Linux file systems are case-sensitive: two files can differ only by
case, and the exact case must be used when opening a file.</p>
<p>File systems in modern Windows are case-insensitive but
case-preserving: although existing files can be opened using any case,
the exact case used to create the file is preserved and available for
programs to query. It is not allowed for two files in the same directory
to differ only by case.</p>
<p>Usually file systems on macOS are case-insensitive. It is possible to
make macOS file systems case-sensitive but that is not the default.</p>
<p>The <code>--vfs-case-insensitive</code> VFS flag controls how rclone
handles these two cases. If its value is "false", rclone passes file
names to the remote as-is. If the flag is "true" (or appears without a
value on the command line), rclone may perform a "fixup" as explained
below.</p>
<p>The user may specify a file name to open/delete/rename/etc with a
case different than what is stored on the remote. If an argument refers
to an existing file with exactly the same name, then the case of the
existing file on the disk will be used. However, if a file name with
exactly the same name is not found but a name differing only by case
exists, rclone will transparently fixup the name. This fixup happens
only when an existing file is requested. Case sensitivity of file names
created anew by rclone is controlled by the underlying remote.</p>
<p>Note that case sensitivity of the operating system running rclone
(the target) may differ from case sensitivity of a file system presented
by rclone (the source). The flag controls whether "fixup" is performed
to satisfy the target.</p>
<p>If the flag is not provided on the command line, then its default
value depends on the operating system where rclone runs: "true" on
Windows and macOS, "false" otherwise. If the flag is provided without a
value, then it is "true".</p>
<p>The <code>--no-unicode-normalization</code> flag controls whether a
similar "fixup" is performed for filenames that differ but are <a
href="https://en.wikipedia.org/wiki/Unicode_equivalence">canonically
equivalent</a> with respect to unicode. Unicode normalization can be
particularly helpful for users of macOS, which prefers form NFD instead
of the NFC used by most other platforms. It is therefore highly
recommended to keep the default of <code>false</code> on macOS, to avoid
encoding compatibility issues.</p>
<p>In the (probably unlikely) event that a directory has multiple
duplicate filenames after applying case and unicode normalization, the
<code>--vfs-block-norm-dupes</code> flag allows hiding these duplicates.
This comes with a performance tradeoff, as rclone will have to scan the
entire directory for duplicates when listing a directory. For this
reason, it is recommended to leave this disabled if not needed. However,
macOS users may wish to consider using it, as otherwise, if a remote
directory contains both NFC and NFD versions of the same filename, an
odd situation will occur: both versions of the file will be visible in
the mount, and both will appear to be editable, however, editing either
version will actually result in only the NFD version getting edited
under the hood. <code>--vfs-block- norm-dupes</code> prevents this
confusion by detecting this scenario, hiding the duplicates, and logging
an error, similar to how this is handled in
<code>rclone sync</code>.</p>
<h2 id="vfs-disk-options-4">VFS Disk Options</h2>
<p>This flag allows you to manually set the statistics about the filing
system. It can be useful when those statistics cannot be read correctly
automatically.</p>
<pre class="text"><code>    --vfs-disk-space-total-size    Manually set the total disk space size (example: 256G, default: -1)</code></pre>
<h2 id="alternate-report-of-used-bytes-4">Alternate report of used
bytes</h2>
<p>Some backends, most notably S3, do not report the amount of bytes
used. If you need this information to be available when running
<code>df</code> on the filesystem, then pass the flag
<code>--vfs-used-is-size</code> to rclone. With this flag set, instead
of relying on the backend to report this information, rclone will scan
the whole remote similar to <code>rclone size</code> and compute the
total used space itself.</p>
<p><strong>WARNING</strong>: Contrary to <code>rclone size</code>, this
flag ignores filters so that the result is accurate. However, this is
very inefficient and may cost lots of API calls resulting in extra
charges. Use it as a last resort and only with caching.</p>
<h2 id="vfs-metadata-4">VFS Metadata</h2>
<p>If you use the <code>--vfs-metadata-extension</code> flag you can get
the VFS to expose files which contain the <a
href="https://rclone.org/docs/#metadata">metadata</a> as a JSON blob.
These files will not appear in the directory listing, but can be
<code>stat</code>-ed and opened and once they have been they
<strong>will</strong> appear in directory listings until the directory
cache expires.</p>
<p>Note that some backends won't create metadata unless you pass in the
<code>--metadata</code> flag.</p>
<p>For example, using <code>rclone mount</code> with
<code>--metadata --vfs-metadata-extension .metadata</code> we get</p>
<pre class="console"><code>$ ls -l /mnt/
total 1048577
-rw-rw-r-- 1 user user 1073741824 Mar  3 16:03 1G

{
        &quot;atime&quot;: &quot;2025-03-04T17:34:22.317069787Z&quot;,
        &quot;btime&quot;: &quot;2025-03-03T16:03:37.708253808Z&quot;,

-rw-rw-r-- 1 user user        185 Mar  3 16:03 1G.metadata</code></pre>
<p>If the file has no metadata it will be returned as <code>{}</code>
and if there is an error reading the metadata the error will be returned
as <code>{"error":"error string"}</code>.</p>
<h2 id="auth-proxy">Auth Proxy</h2>
<p>If you supply the parameter
<code>--auth-proxy /path/to/program</code> then rclone will use that
program to generate backends on the fly which then are used to
authenticate incoming requests. This uses a simple JSON based protocol
with input on STDIN and output on STDOUT.</p>
<p><strong>PLEASE NOTE:</strong> <code>--auth-proxy</code> and
<code>--authorized-keys</code> cannot be used together, if
<code>--auth-proxy</code> is set the authorized keys option will be
ignored.</p>
<p>There is an example program <a
href="https://github.com/rclone/rclone/blob/master/bin/test_proxy.py">bin/test_proxy.py</a>
in the rclone source code.</p>
<p>The program's job is to take a <code>user</code> and
<code>pass</code> on the input and turn those into the config for a
backend on STDOUT in JSON format. This config will have any default
parameters for the backend added, but it won't use configuration from
environment variables or command line options - it is the job of the
proxy program to make a complete config.</p>
<p>This config generated must have this extra parameter</p>
<ul>
<li><code>_root</code> - root to use for the backend</li>
</ul>
<p>And it may have this parameter</p>
<ul>
<li><code>_obscure</code> - comma separated strings for parameters to
obscure</li>
</ul>
<p>If password authentication was used by the client, input to the proxy
process (on STDIN) would look similar to this:</p>
<div class="sourceCode" id="cb486"><pre

<p>If public-key authentication was used by the client, input to the
proxy process (on STDIN) would look similar to this:</p>
<div class="sourceCode" id="cb487"><pre

<p>This would mean that an SFTP backend would be created on the fly for
the <code>user</code> and <code>pass</code>/<code>public_key</code>
returned in the output to the host given. Note that since
<code>_obscure</code> is set to <code>pass</code>, rclone will obscure
the <code>pass</code> parameter before creating the backend (which is
required for sftp backends).</p>
<p>The program can manipulate the supplied <code>user</code> in any way,
for example to make proxy to many different sftp backends, you could
make the <code>user</code> be <code>user@example.com</code> and then set
the <code>host</code> to <code>example.com</code> in the output and the
user to <code>user</code>. For security you'd probably want to restrict
the <code>host</code> to a limited list.</p>
<p>Note that an internal cache is keyed on <code>user</code> so only use
that for configuration, don't use <code>pass</code> or
<code>public_key</code>. This also means that if a user's password or
public-key is changed the cache will need to expire (which takes 5 mins)
before it takes effect.</p>
<p>This can be used to build general purpose proxies to any kind of
backend that rclone supports.</p>

<h1 id="rclone-serve-http">rclone serve http</h1>
<p>Serve the remote over HTTP.</p>
<h2 id="synopsis-73">Synopsis</h2>
<p>Run a basic web server to serve a remote over HTTP. This can be
viewed in a web browser or you can make a remote of type http read from
it.</p>
<p>You can use the filter flags (e.g. <code>--include</code>,
<code>--exclude</code>) to control what is served.</p>
<p>The server will log errors. Use <code>-v</code> to see access
logs.</p>
<p><code>--bwlimit</code> will be respected for file transfers. Use
<code>--stats</code> to control the stats printing.</p>
<h2 id="server-options-3">Server options</h2>
<p>Use <code>--addr</code> to specify which IP address and port the
server should listen on, eg <code>--addr 1.2.3.4:8000</code> or
<code>--addr :8080</code> to listen to all IPs. By default it only
listens on localhost. You can use port :0 to let the OS choose an
available port.</p>
<p>If you set <code>--addr</code> to listen on a public or LAN
accessible IP address then using Authentication is advised - see the
next section for info.</p>
<p>You can use a unix socket by setting the url to
<code>unix:///path/to/socket</code> or just by using an absolute path
name.</p>
<p><code>--addr</code> may be repeated to listen on multiple
IPs/ports/sockets. Socket activation, described further below, can also
be used to accomplish the same.</p>
<p><code>--server-read-timeout</code> and
<code>--server-write-timeout</code> can be used to control the timeouts
on the server. Note that this is the total time for a transfer.</p>
<p><code>--max-header-bytes</code> controls the maximum number of bytes
the server will accept in the HTTP header.</p>
<p><code>--baseurl</code> controls the URL prefix that rclone serves
from. By default rclone will serve from the root. If you used
<code>--baseurl "/rclone"</code> then rclone would serve from a URL
starting with "/rclone/". This is useful if you wish to proxy rclone
serve. Rclone automatically inserts leading and trailing "/" on
<code>--baseurl</code>, so <code>--baseurl "rclone"</code>,
<code>--baseurl "/rclone"</code> and <code>--baseurl "/rclone/"</code>
are all treated identically.</p>
<p><code>--disable-zip</code> may be set to disable the zipping download
option.</p>
<h3 id="tls-ssl-1">TLS (SSL)</h3>
<p>By default this will serve over http. If you want you can serve over
https. You will need to supply the <code>--cert</code> and
<code>--key</code> flags. If you wish to do client side certificate
validation then you will need to supply <code>--client-ca</code>
also.</p>
<p><code>--cert</code> must be set to the path of a file containing
either a PEM encoded certificate, or a concatenation of that with the CA
certificate. <code>--key</code> must be set to the path of a file with
the PEM encoded private key. If setting <code>--client-ca</code>, it
should be set to the path of a file with PEM encoded client certificate
authority certificates.</p>
<p><code>--min-tls-version</code> is minimum TLS version that is
acceptable. Valid values are "tls1.0", "tls1.1", "tls1.2" and "tls1.3"
(default "tls1.0").</p>
<h2 id="socket-activation-1">Socket activation</h2>
<p>Instead of the listening addresses specified above, rclone will
listen to all FDs passed by the service manager, if any (and ignore any
arguments passed by <code>--addr</code>).</p>
<p>This allows rclone to be a socket-activated service. It can be
configured with .socket and .service unit files as described in <a
href="https://www.freedesktop.org/software/systemd/man/latest/systemd.socket.html"
class="uri">https://www.freedesktop.org/software/systemd/man/latest/systemd.socket.html</a>.</p>
<p>Socket activation can be tested ad-hoc with the
<code>systemd-socket-activate</code>command</p>
<pre class="console"><code>systemd-socket-activate -l 8000 -- rclone serve</code></pre>
<p>This will socket-activate rclone on the first connection to port 8000
over TCP.</p>
<h3 id="template-1">Template</h3>
<p><code>--template</code> allows a user to specify a custom markup
template for HTTP and WebDAV serve functions. The server exports the

<h3 id="authentication-2">Authentication</h3>
<p>By default this will serve files without needing a login.</p>
<p>You can either use an htpasswd file which can take lots of users, or
set a single username and password with the <code>--user</code> and
<code>--pass</code> flags.</p>
<p>Alternatively, you can have the reverse proxy manage authentication
and use the username provided in the configured header with
<code>--user-from-header</code> (e.g.,
<code>--user-from-header=x-remote-user</code>). Ensure the proxy is
trusted and headers cannot be spoofed, as misconfiguration may lead to
unauthorized access.</p>
<p>If either of the above authentication methods is not configured and
client certificates are required by the <code>--client-ca</code> flag
passed to the server, the client certificate common name will be
considered as the username.</p>
<p>Use <code>--htpasswd /path/to/htpasswd</code> to provide an htpasswd
file. This is in standard apache format and supports MD5, SHA1 and
BCrypt for basic authentication. Bcrypt is recommended.</p>
<p>To create an htpasswd file:</p>
<pre class="console"><code>touch htpasswd
htpasswd -B htpasswd user
htpasswd -B htpasswd anotherUser</code></pre>
<p>The password file can be updated while rclone is running.</p>
<p>Use <code>--realm</code> to set the authentication realm.</p>
<p>Use <code>--salt</code> to change the password hashing salt from the
default.</p>
<h2 id="vfs---virtual-file-system-5">VFS - Virtual File System</h2>
<p>This command uses the VFS layer. This adapts the cloud storage
objects that rclone uses into something which looks much more like a
disk filing system.</p>
<p>Cloud storage objects have lots of properties which aren't like disk
files - you can't extend them or write to the middle of them, so the VFS
layer has to deal with that. Because there is no one right way of doing
this there are various options explained below.</p>
<p>The VFS layer also implements a directory cache - this caches info
about files and directories (but not the data) in memory.</p>
<h2 id="vfs-directory-cache-5">VFS Directory Cache</h2>
<p>Using the <code>--dir-cache-time</code> flag, you can control how
long a directory should be considered up to date and not refreshed from
the backend. Changes made through the VFS will appear immediately or
invalidate the cache.</p>
<pre class="text"><code>    --dir-cache-time duration   Time to cache directory entries for (default 5m0s)
    --poll-interval duration    Time to wait between polling for changes. Must be smaller than dir-cache-time. Only on supported remotes. Set to 0 to disable (default 1m0s)</code></pre>
<p>However, changes made directly on the cloud storage by the web
interface or a different copy of rclone will only be picked up once the
directory cache expires if the backend configured does not support
polling for changes. If the backend supports polling, changes will be
picked up within the polling interval.</p>
<p>You can send a <code>SIGHUP</code> signal to rclone for it to flush
all directory caches, regardless of how old they are. Assuming only one
rclone instance is running, you can reset the cache like this:</p>
<pre class="console"><code>kill -SIGHUP $(pidof rclone)</code></pre>
<p>If you configure rclone with a <a href="/rc">remote control</a> then
you can use rclone rc to flush the whole directory cache:</p>
<pre class="console"><code>rclone rc vfs/forget</code></pre>
<p>Or individual files or directories:</p>
<pre class="console"><code>rclone rc vfs/forget file=path/to/file dir=path/to/dir</code></pre>
<h2 id="vfs-file-buffering-5">VFS File Buffering</h2>
<p>The <code>--buffer-size</code> flag determines the amount of memory,
that will be used to buffer data in advance.</p>
<p>Each open file will try to keep the specified amount of data in
memory at all times. The buffered data is bound to one open file and
won't be shared.</p>
<p>This flag is a upper limit for the used memory per open file. The
buffer will only use memory for data that is downloaded but not not yet
read. If the buffer is empty, only a small amount of memory will be
used.</p>
<p>The maximum memory used by rclone for buffering can be up to
<code>--buffer-size * open files</code>.</p>
<h2 id="vfs-file-caching-5">VFS File Caching</h2>
<p>These flags control the VFS file caching options. File caching is
necessary to make the VFS layer appear compatible with a normal file
system. It can be disabled at the cost of some compatibility.</p>
<p>For example you'll need to enable VFS caching if you want to read and
write simultaneously to a file. See below for more details.</p>
<p>Note that the VFS cache is separate from the cache backend and you
may find that you need one or the other or both.</p>
<pre class="text"><code>    --cache-dir string                     Directory rclone will use for caching.
    --vfs-cache-mode CacheMode             Cache mode off|minimal|writes|full (default off)
    --vfs-cache-max-age duration           Max time since last access of objects in the cache (default 1h0m0s)
    --vfs-cache-max-size SizeSuffix        Max total size of objects in the cache (default off)
    --vfs-cache-min-free-space SizeSuffix  Target minimum free space on the disk containing the cache (default off)
    --vfs-cache-poll-interval duration     Interval to poll the cache for stale objects (default 1m0s)
    --vfs-write-back duration              Time to writeback files after last use when using cache (default 5s)</code></pre>
<p>If run with <code>-vv</code> rclone will print the location of the
file cache. The files are stored in the user cache file area which is OS
dependent but can be controlled with <code>--cache-dir</code> or setting
the appropriate environment variable.</p>
<p>The cache has 4 different modes selected by
<code>--vfs-cache-mode</code>. The higher the cache mode the more
compatible rclone becomes at the cost of using disk space.</p>
<p>Note that files are written back to the remote only when they are
closed and if they haven't been accessed for
<code>--vfs-write-back</code> seconds. If rclone is quit or dies with
files that haven't been uploaded, these will be uploaded next time
rclone is run with the same flags.</p>
<p>If using <code>--vfs-cache-max-size</code> or
<code>--vfs-cache-min-free-space</code> note that the cache may exceed
these quotas for two reasons. Firstly because it is only checked every
<code>--vfs-cache-poll-interval</code>. Secondly because open files
cannot be evicted from the cache. When <code>--vfs-cache-max-size</code>
or <code>--vfs-cache-min-free-space</code> is exceeded, rclone will
attempt to evict the least accessed files from the cache first. rclone
will start with files that haven't been accessed for the longest. This
cache flushing strategy is efficient and more relevant files are likely
to remain cached.</p>
<p>The <code>--vfs-cache-max-age</code> will evict files from the cache
after the set time since last access has passed. The default value of 1
hour will start evicting files from cache that haven't been accessed for
1 hour. When a cached file is accessed the 1 hour timer is reset to 0
and will wait for 1 more hour before evicting. Specify the time with
standard notation, s, m, h, d, w .</p>
<p>You <strong>should not</strong> run two copies of rclone using the
same VFS cache with the same or overlapping remotes if using
<code>--vfs-cache-mode &gt; off</code>. This can potentially cause data
corruption if you do. You can work around this by giving each rclone its
own cache hierarchy with <code>--cache-dir</code>. You don't need to
worry about this if the remotes in use don't overlap.</p>
<h3 id="vfs-cache-mode-off-5">--vfs-cache-mode off</h3>
<p>In this mode (the default) the cache will read directly from the
remote and write directly to the remote without caching anything on
disk.</p>
<p>This will mean some operations are not possible</p>
<ul>
<li>Files can't be opened for both read AND write</li>
<li>Files opened for write can't be seeked</li>
<li>Existing files opened for write must have O_TRUNC set</li>
<li>Files open for read with O_TRUNC will be opened write only</li>
<li>Files open for write only will behave as if O_TRUNC was
supplied</li>
<li>Open modes O_APPEND, O_TRUNC are ignored</li>
<li>If an upload fails it can't be retried</li>
</ul>
<h3 id="vfs-cache-mode-minimal-5">--vfs-cache-mode minimal</h3>
<p>This is very similar to "off" except that files opened for read AND
write will be buffered to disk. This means that files opened for write
will be a lot more compatible, but uses the minimal disk space.</p>
<p>These operations are not possible</p>
<ul>
<li>Files opened for write only can't be seeked</li>
<li>Existing files opened for write must have O_TRUNC set</li>
<li>Files opened for write only will ignore O_APPEND, O_TRUNC</li>
<li>If an upload fails it can't be retried</li>
</ul>
<h3 id="vfs-cache-mode-writes-5">--vfs-cache-mode writes</h3>
<p>In this mode files opened for read only are still read directly from
the remote, write only and read/write files are buffered to disk
first.</p>
<p>This mode should support all normal file system operations.</p>
<p>If an upload fails it will be retried at exponentially increasing
intervals up to 1 minute.</p>
<h3 id="vfs-cache-mode-full-5">--vfs-cache-mode full</h3>
<p>In this mode all reads and writes are buffered to and from disk. When
data is read from the remote this is buffered to disk as well.</p>
<p>In this mode the files in the cache will be sparse files and rclone
will keep track of which bits of the files it has downloaded.</p>
<p>So if an application only reads the starts of each file, then rclone
will only buffer the start of the file. These files will appear to be
their full size in the cache, but they will be sparse files with only
the data that has been downloaded present in them.</p>
<p>This mode should support all normal file system operations and is
otherwise identical to <code>--vfs-cache-mode</code> writes.</p>
<p>When reading a file rclone will read <code>--buffer-size</code> plus
<code>--vfs-read-ahead</code> bytes ahead. The
<code>--buffer-size</code> is buffered in memory whereas the
<code>--vfs-read-ahead</code> is buffered on disk.</p>
<p>When using this mode it is recommended that
<code>--buffer-size</code> is not set too large and
<code>--vfs-read-ahead</code> is set large if required.</p>
<p><strong>IMPORTANT</strong> not all file systems support sparse files.
In particular FAT/exFAT do not. Rclone will perform very badly if the
cache directory is on a filesystem which doesn't support sparse files
and it will log an ERROR message if one is detected.</p>
<h3 id="fingerprinting-5">Fingerprinting</h3>
<p>Various parts of the VFS use fingerprinting to see if a local file
copy has changed relative to a remote file. Fingerprints are made
from:</p>
<ul>
<li>size</li>
<li>modification time</li>
<li>hash</li>
</ul>
<p>where available on an object.</p>
<p>On some backends some of these attributes are slow to read (they take
an extra API call per object, or extra work per object).</p>
<p>For example <code>hash</code> is slow with the <code>local</code> and
<code>sftp</code> backends as they have to read the entire file and hash
it, and <code>modtime</code> is slow with the <code>s3</code>,
<code>swift</code>, <code>ftp</code> and <code>qinqstor</code> backends
because they need to do an extra API call to fetch it.</p>
<p>If you use the <code>--vfs-fast-fingerprint</code> flag then rclone
will not include the slow operations in the fingerprint. This makes the
fingerprinting less accurate but much faster and will improve the
opening time of cached files.</p>
<p>If you are running a vfs cache over <code>local</code>,
<code>s3</code> or <code>swift</code> backends then using this flag is
recommended.</p>
<p>Note that if you change the value of this flag, the fingerprints of
the files in the cache may be invalidated and the files will need to be
downloaded again.</p>
<h2 id="vfs-chunked-reading-5">VFS Chunked Reading</h2>
<p>When rclone reads files from a remote it reads them in chunks. This
means that rather than requesting the whole file rclone reads the chunk
specified. This can reduce the used download quota for some remotes by
requesting only chunks from the remote that are actually read, at the
cost of an increased number of requests.</p>
<p>These flags control the chunking:</p>
<pre class="text"><code>    --vfs-read-chunk-size SizeSuffix        Read the source objects in chunks (default 128M)
    --vfs-read-chunk-size-limit SizeSuffix  Max chunk doubling size (default off)
    --vfs-read-chunk-streams int            The number of parallel streams to read at once</code></pre>
<p>The chunking behaves differently depending on the
<code>--vfs-read-chunk-streams</code> parameter.</p>
<h3
id="vfs-read-chunk-streams-0-10"><code>--vfs-read-chunk-streams</code>
== 0</h3>
<p>Rclone will start reading a chunk of size
<code>--vfs-read-chunk-size</code>, and then double the size for each
read. When <code>--vfs-read-chunk-size-limit</code> is specified, and
greater than <code>--vfs-read-chunk-size</code>, the chunk size for each
open file will get doubled only until the specified value is reached. If
the value is "off", which is the default, the limit is disabled and the
chunk size will grow indefinitely.</p>
<p>With <code>--vfs-read-chunk-size 100M</code> and
<code>--vfs-read-chunk-size-limit 0</code> the following parts will be
downloaded: 0-100M, 100M-200M, 200M-300M, 300M-400M and so on. When
<code>--vfs-read-chunk-size-limit 500M</code> is specified, the result
would be 0-100M, 100M-300M, 300M-700M, 700M-1200M, 1200M-1700M and so
on.</p>
<p>Setting <code>--vfs-read-chunk-size</code> to <code>0</code> or "off"
disables chunked reading.</p>
<p>The chunks will not be buffered in memory.</p>
<h3
id="vfs-read-chunk-streams-0-11"><code>--vfs-read-chunk-streams</code>
&gt; 0</h3>
<p>Rclone reads <code>--vfs-read-chunk-streams</code> chunks of size
<code>--vfs-read-chunk-size</code> concurrently. The size for each read
will stay constant.</p>
<p>This improves performance performance massively on high latency links
or very high bandwidth links to high performance object stores.</p>
<p>Some experimentation will be needed to find the optimum values of
<code>--vfs-read-chunk-size</code> and
<code>--vfs-read-chunk-streams</code> as these will depend on the
backend in use and the latency to the backend.</p>
<p>For high performance object stores (eg AWS S3) a reasonable place to
start might be <code>--vfs-read-chunk-streams 16</code> and
<code>--vfs-read-chunk-size 4M</code>. In testing with AWS S3 the
performance scaled roughly as the <code>--vfs-read-chunk-streams</code>
setting.</p>
<p>Similar settings should work for high latency links, but depending on
the latency they may need more <code>--vfs-read-chunk-streams</code> in
order to get the throughput.</p>
<h2 id="vfs-performance-5">VFS Performance</h2>
<p>These flags may be used to enable/disable features of the VFS for
performance or other reasons. See also the <a
href="#vfs-chunked-reading">chunked reading</a> feature.</p>
<p>In particular S3 and Swift benefit hugely from the
<code>--no-modtime</code> flag (or use <code>--use-server-modtime</code>
for a slightly different effect) as each read of the modification time
takes a transaction.</p>
<pre class="text"><code>    --no-checksum     Don&#39;t compare checksums on up/download.
    --no-modtime      Don&#39;t read/write the modification time (can speed things up).
    --no-seek         Don&#39;t allow seeking in files.
    --read-only       Only allow read-only access.</code></pre>
<p>Sometimes rclone is delivered reads or writes out of order. Rather
than seeking rclone will wait a short time for the in sequence read or
write to come in. These flags only come into effect when not using an on
disk cache file.</p>
<pre class="text"><code>    --vfs-read-wait duration   Time to wait for in-sequence read before seeking (default 20ms)
    --vfs-write-wait duration  Time to wait for in-sequence write before giving error (default 1s)</code></pre>
<p>When using VFS write caching (<code>--vfs-cache-mode</code> with
value writes or full), the global flag <code>--transfers</code> can be
set to adjust the number of parallel uploads of modified files from the
cache (the related global flag <code>--checkers</code> has no effect on
the VFS).</p>
<pre class="text"><code>    --transfers int  Number of file transfers to run in parallel (default 4)</code></pre>
<h2 id="symlinks-5">Symlinks</h2>
<p>By default the VFS does not support symlinks. However this may be
enabled with either of the following flags:</p>
<pre class="text"><code>    --links      Translate symlinks to/from regular files with a &#39;.rclonelink&#39; extension.
    --vfs-links  Translate symlinks to/from regular files with a &#39;.rclonelink&#39; extension for the VFS</code></pre>
<p>As most cloud storage systems do not support symlinks directly,
rclone stores the symlink as a normal file with a special extension. So
a file which appears as a symlink <code>link-to-file.txt</code> would be
stored on cloud storage as <code>link-to-file.txt.rclonelink</code> and
the contents would be the path to the symlink destination.</p>
<p>Note that <code>--links</code> enables symlink translation globally
in rclone - this includes any backend which supports the concept (for
example the local backend). <code>--vfs-links</code> just enables it for
the VFS layer.</p>
<p>This scheme is compatible with that used by the <a
href="https://rclone.org/local/#symlinks-junction-points">local backend
with the --local-links flag</a>.</p>
<p>The <code>--vfs-links</code> flag has been designed for
<code>rclone mount</code>, <code>rclone nfsmount</code> and
<code>rclone serve nfs</code>.</p>
<p>It hasn't been tested with the other <code>rclone serve</code>
commands yet.</p>
<p>A limitation of the current implementation is that it expects the
caller to resolve sub-symlinks. For example given this directory
tree</p>
<pre class="text"><code>.
├── dir
│   └── file.txt
└── linked-dir -&gt; dir</code></pre>
<p>The VFS will correctly resolve <code>linked-dir</code> but not
<code>linked-dir/file.txt</code>. This is not a problem for the tested
commands but may be for other commands.</p>
<p><strong>Note</strong> that there is an outstanding issue with symlink
support <a href="https://github.com/rclone/rclone/issues/8245">issue
#8245</a> with duplicate files being created when symlinks are moved
into directories where there is a file of the same name (or vice
versa).</p>
<h2 id="vfs-case-sensitivity-5">VFS Case Sensitivity</h2>
<p>Linux file systems are case-sensitive: two files can differ only by
case, and the exact case must be used when opening a file.</p>
<p>File systems in modern Windows are case-insensitive but
case-preserving: although existing files can be opened using any case,
the exact case used to create the file is preserved and available for
programs to query. It is not allowed for two files in the same directory
to differ only by case.</p>
<p>Usually file systems on macOS are case-insensitive. It is possible to
make macOS file systems case-sensitive but that is not the default.</p>
<p>The <code>--vfs-case-insensitive</code> VFS flag controls how rclone
handles these two cases. If its value is "false", rclone passes file
names to the remote as-is. If the flag is "true" (or appears without a
value on the command line), rclone may perform a "fixup" as explained
below.</p>
<p>The user may specify a file name to open/delete/rename/etc with a
case different than what is stored on the remote. If an argument refers
to an existing file with exactly the same name, then the case of the
existing file on the disk will be used. However, if a file name with
exactly the same name is not found but a name differing only by case
exists, rclone will transparently fixup the name. This fixup happens
only when an existing file is requested. Case sensitivity of file names
created anew by rclone is controlled by the underlying remote.</p>
<p>Note that case sensitivity of the operating system running rclone
(the target) may differ from case sensitivity of a file system presented
by rclone (the source). The flag controls whether "fixup" is performed
to satisfy the target.</p>
<p>If the flag is not provided on the command line, then its default
value depends on the operating system where rclone runs: "true" on
Windows and macOS, "false" otherwise. If the flag is provided without a
value, then it is "true".</p>
<p>The <code>--no-unicode-normalization</code> flag controls whether a
similar "fixup" is performed for filenames that differ but are <a
href="https://en.wikipedia.org/wiki/Unicode_equivalence">canonically
equivalent</a> with respect to unicode. Unicode normalization can be
particularly helpful for users of macOS, which prefers form NFD instead
of the NFC used by most other platforms. It is therefore highly
recommended to keep the default of <code>false</code> on macOS, to avoid
encoding compatibility issues.</p>
<p>In the (probably unlikely) event that a directory has multiple
duplicate filenames after applying case and unicode normalization, the
<code>--vfs-block-norm-dupes</code> flag allows hiding these duplicates.
This comes with a performance tradeoff, as rclone will have to scan the
entire directory for duplicates when listing a directory. For this
reason, it is recommended to leave this disabled if not needed. However,
macOS users may wish to consider using it, as otherwise, if a remote
directory contains both NFC and NFD versions of the same filename, an
odd situation will occur: both versions of the file will be visible in
the mount, and both will appear to be editable, however, editing either
version will actually result in only the NFD version getting edited
under the hood. <code>--vfs-block- norm-dupes</code> prevents this
confusion by detecting this scenario, hiding the duplicates, and logging
an error, similar to how this is handled in
<code>rclone sync</code>.</p>
<h2 id="vfs-disk-options-5">VFS Disk Options</h2>
<p>This flag allows you to manually set the statistics about the filing
system. It can be useful when those statistics cannot be read correctly
automatically.</p>
<pre class="text"><code>    --vfs-disk-space-total-size    Manually set the total disk space size (example: 256G, default: -1)</code></pre>
<h2 id="alternate-report-of-used-bytes-5">Alternate report of used
bytes</h2>
<p>Some backends, most notably S3, do not report the amount of bytes
used. If you need this information to be available when running
<code>df</code> on the filesystem, then pass the flag
<code>--vfs-used-is-size</code> to rclone. With this flag set, instead
of relying on the backend to report this information, rclone will scan
the whole remote similar to <code>rclone size</code> and compute the
total used space itself.</p>
<p><strong>WARNING</strong>: Contrary to <code>rclone size</code>, this
flag ignores filters so that the result is accurate. However, this is
very inefficient and may cost lots of API calls resulting in extra
charges. Use it as a last resort and only with caching.</p>
<h2 id="vfs-metadata-5">VFS Metadata</h2>
<p>If you use the <code>--vfs-metadata-extension</code> flag you can get
the VFS to expose files which contain the <a
href="https://rclone.org/docs/#metadata">metadata</a> as a JSON blob.
These files will not appear in the directory listing, but can be
<code>stat</code>-ed and opened and once they have been they
<strong>will</strong> appear in directory listings until the directory
cache expires.</p>
<p>Note that some backends won't create metadata unless you pass in the
<code>--metadata</code> flag.</p>
<p>For example, using <code>rclone mount</code> with
<code>--metadata --vfs-metadata-extension .metadata</code> we get</p>
<pre class="console"><code>$ ls -l /mnt/
total 1048577
-rw-rw-r-- 1 user user 1073741824 Mar  3 16:03 1G

{
        &quot;atime&quot;: &quot;2025-03-04T17:34:22.317069787Z&quot;,

-rw-rw-r-- 1 user user        185 Mar  3 16:03 1G.metadata</code></pre>
<p>If the file has no metadata it will be returned as <code>{}</code>
and if there is an error reading the metadata the error will be returned
as <code>{"error":"error string"}</code>.</p>
<h2 id="auth-proxy-1">Auth Proxy</h2>
<p>If you supply the parameter
<code>--auth-proxy /path/to/program</code> then rclone will use that
program to generate backends on the fly which then are used to
authenticate incoming requests. This uses a simple JSON based protocol
with input on STDIN and output on STDOUT.</p>
<p><strong>PLEASE NOTE:</strong> <code>--auth-proxy</code> and
<code>--authorized-keys</code> cannot be used together, if
<code>--auth-proxy</code> is set the authorized keys option will be
ignored.</p>
<p>There is an example program <a
href="https://github.com/rclone/rclone/blob/master/bin/test_proxy.py">bin/test_proxy.py</a>
in the rclone source code.</p>
<p>The program's job is to take a <code>user</code> and
<code>pass</code> on the input and turn those into the config for a
backend on STDOUT in JSON format. This config will have any default
parameters for the backend added, but it won't use configuration from
environment variables or command line options - it is the job of the
proxy program to make a complete config.</p>
<p>This config generated must have this extra parameter</p>
<ul>
<li><code>_root</code> - root to use for the backend</li>
</ul>
<p>And it may have this parameter</p>
<ul>
<li><code>_obscure</code> - comma separated strings for parameters to
obscure</li>
</ul>
<p>If password authentication was used by the client, input to the proxy
process (on STDIN) would look similar to this:</p>
<div class="sourceCode" id="cb507"><pre

<p>If public-key authentication was used by the client, input to the
proxy process (on STDIN) would look similar to this:</p>

<p>This would mean that an SFTP backend would be created on the fly for
the <code>user</code> and <code>pass</code>/<code>public_key</code>
returned in the output to the host given. Note that since
<code>_obscure</code> is set to <code>pass</code>, rclone will obscure
the <code>pass</code> parameter before creating the backend (which is
required for sftp backends).</p>
<p>The program can manipulate the supplied <code>user</code> in any way,
for example to make proxy to many different sftp backends, you could
make the <code>user</code> be <code>user@example.com</code> and then set
the <code>host</code> to <code>example.com</code> in the output and the
user to <code>user</code>. For security you'd probably want to restrict
the <code>host</code> to a limited list.</p>
<p>Note that an internal cache is keyed on <code>user</code> so only use
that for configuration, don't use <code>pass</code> or
<code>public_key</code>. This also means that if a user's password or
public-key is changed the cache will need to expire (which takes 5 mins)
before it takes effect.</p>
<p>This can be used to build general purpose proxies to any kind of
backend that rclone supports.</p>

<h1 id="rclone-serve-nfs">rclone serve nfs</h1>
<p>Serve the remote as an NFS mount</p>
<h2 id="synopsis-74">Synopsis</h2>
<p>Create an NFS server that serves the given remote over the
network.</p>
<p>This implements an NFSv3 server to serve any rclone remote via
NFS.</p>
<p>The primary purpose for this command is to enable the <a
href="https://rclone.org/commands/rclone_mount/">mount command</a> on
recent macOS versions where installing FUSE is very cumbersome.</p>
<p>This server does not implement any authentication so any client will
be able to access the data. To limit access, you can use
<code>serve nfs</code> on the loopback address or rely on secure tunnels
(such as SSH) or use firewalling.</p>
<p>For this reason, by default, a random TCP port is chosen and the
loopback interface is used for the listening address by default; meaning
that it is only available to the local machine. If you want other
machines to access the NFS mount over local network, you need to specify
the listening address and port using the <code>--addr</code> flag.</p>
<p>Modifying files through the NFS protocol requires VFS caching.
Usually you will need to specify <code>--vfs-cache-mode</code> in order
to be able to write to the mountpoint (<code>full</code> is
recommended). If you don't specify VFS cache mode, the mount will be
read-only.</p>
<p><code>--nfs-cache-type</code> controls the type of the NFS handle
cache. By default this is <code>memory</code> where new handles will be
randomly allocated when needed. These are stored in memory. If the
server is restarted the handle cache will be lost and connected NFS
clients will get stale handle errors.</p>
<p><code>--nfs-cache-type disk</code> uses an on disk NFS handle cache.
Rclone hashes the path of the object and stores it in a file named after
the hash. These hashes are stored on disk the directory controlled by
<code>--cache-dir</code> or the exact directory may be specified with
<code>--nfs-cache-dir</code>. Using this means that the NFS server can
be restarted at will without affecting the connected clients.</p>
<p><code>--nfs-cache-type symlink</code> is similar to
<code>--nfs-cache-type disk</code> in that it uses an on disk cache, but
the cache entries are held as symlinks. Rclone will use the handle of
the underlying file as the NFS handle which improves performance. This
sort of cache can't be backed up and restored as the underlying handles
will change. This is Linux only. It requires running rclone as root or
with <code>CAP_DAC_READ_SEARCH</code>. You can run rclone with this
extra permission by doing this to the rclone binary
<code>sudo setcap cap_dac_read_search+ep /path/to/rclone</code>.</p>
<p><code>--nfs-cache-handle-limit</code> controls the maximum number of
cached NFS handles stored by the caching handler. This should not be set
too low or you may experience errors when trying to access files. The
default is <code>1000000</code>, but consider lowering this limit if the
server's system resource usage causes problems. This is only used by the
<code>memory</code> type cache.</p>
<p>To serve NFS over the network use following command:</p>
<div class="sourceCode" id="cb513"><pre
class="sourceCode sh"><code class="sourceCode bash"><span id="cb513-1"><a href="#cb513-1" aria-hidden="true" tabindex="-1"></a><span class="ex">rclone</span> serve nfs remote: <span class="at">--addr</span> 0.0.0.0:<span class="va">$PORT</span> <span class="at">--vfs-cache-mode</span><span class="op">=</span>full</span></code></pre></div>
<p>This specifies a port that can be used in the mount command. To mount
the server under Linux/macOS, use the following command:</p>
<div class="sourceCode" id="cb514"><pre
class="sourceCode sh"><code class="sourceCode bash"><span id="cb514-1"><a href="#cb514-1" aria-hidden="true" tabindex="-1"></a><span class="fu">mount</span> <span class="at">-t</span> nfs <span class="at">-o</span> port=<span class="va">$PORT</span>,mountport=<span class="va">$PORT</span>,tcp <span class="va">$HOSTNAME</span>:/ path/to/mountpoint</span></code></pre></div>
<p>Where <code>$PORT</code> is the same port number used in the
<code>serve nfs</code> command and <code>$HOSTNAME</code> is the network
address of the machine that <code>serve nfs</code> was run on.</p>
<p>If <code>--vfs-metadata-extension</code> is in use then for the
<code>--nfs-cache-type disk</code> and
<code>--nfs-cache-type cache</code> the metadata files will have the
file handle of their parent file suffixed with
<code>0x00, 0x00, 0x00, 0x01</code>. This means they can be looked up
directly from the parent file handle is desired.</p>
<p>This command is only available on Unix platforms.</p>
<h2 id="vfs---virtual-file-system-6">VFS - Virtual File System</h2>
<p>This command uses the VFS layer. This adapts the cloud storage
objects that rclone uses into something which looks much more like a
disk filing system.</p>
<p>Cloud storage objects have lots of properties which aren't like disk
files - you can't extend them or write to the middle of them, so the VFS
layer has to deal with that. Because there is no one right way of doing
this there are various options explained below.</p>
<p>The VFS layer also implements a directory cache - this caches info
about files and directories (but not the data) in memory.</p>
<h2 id="vfs-directory-cache-6">VFS Directory Cache</h2>
<p>Using the <code>--dir-cache-time</code> flag, you can control how
long a directory should be considered up to date and not refreshed from
the backend. Changes made through the VFS will appear immediately or
invalidate the cache.</p>
<pre class="text"><code>    --dir-cache-time duration   Time to cache directory entries for (default 5m0s)
    --poll-interval duration    Time to wait between polling for changes. Must be smaller than dir-cache-time. Only on supported remotes. Set to 0 to disable (default 1m0s)</code></pre>
<p>However, changes made directly on the cloud storage by the web
interface or a different copy of rclone will only be picked up once the
directory cache expires if the backend configured does not support
polling for changes. If the backend supports polling, changes will be
picked up within the polling interval.</p>
<p>You can send a <code>SIGHUP</code> signal to rclone for it to flush
all directory caches, regardless of how old they are. Assuming only one
rclone instance is running, you can reset the cache like this:</p>
<pre class="console"><code>kill -SIGHUP $(pidof rclone)</code></pre>
<p>If you configure rclone with a <a href="/rc">remote control</a> then
you can use rclone rc to flush the whole directory cache:</p>
<pre class="console"><code>rclone rc vfs/forget</code></pre>
<p>Or individual files or directories:</p>
<pre class="console"><code>rclone rc vfs/forget file=path/to/file dir=path/to/dir</code></pre>
<h2 id="vfs-file-buffering-6">VFS File Buffering</h2>
<p>The <code>--buffer-size</code> flag determines the amount of memory,
that will be used to buffer data in advance.</p>
<p>Each open file will try to keep the specified amount of data in
memory at all times. The buffered data is bound to one open file and
won't be shared.</p>
<p>This flag is a upper limit for the used memory per open file. The
buffer will only use memory for data that is downloaded but not not yet
read. If the buffer is empty, only a small amount of memory will be
used.</p>
<p>The maximum memory used by rclone for buffering can be up to
<code>--buffer-size * open files</code>.</p>
<h2 id="vfs-file-caching-6">VFS File Caching</h2>
<p>These flags control the VFS file caching options. File caching is
necessary to make the VFS layer appear compatible with a normal file
system. It can be disabled at the cost of some compatibility.</p>
<p>For example you'll need to enable VFS caching if you want to read and
write simultaneously to a file. See below for more details.</p>
<p>Note that the VFS cache is separate from the cache backend and you
may find that you need one or the other or both.</p>
<pre class="text"><code>    --cache-dir string                     Directory rclone will use for caching.
    --vfs-cache-mode CacheMode             Cache mode off|minimal|writes|full (default off)
    --vfs-cache-max-age duration           Max time since last access of objects in the cache (default 1h0m0s)
    --vfs-cache-max-size SizeSuffix        Max total size of objects in the cache (default off)
    --vfs-cache-min-free-space SizeSuffix  Target minimum free space on the disk containing the cache (default off)
    --vfs-cache-poll-interval duration     Interval to poll the cache for stale objects (default 1m0s)
    --vfs-write-back duration              Time to writeback files after last use when using cache (default 5s)</code></pre>
<p>If run with <code>-vv</code> rclone will print the location of the
file cache. The files are stored in the user cache file area which is OS
dependent but can be controlled with <code>--cache-dir</code> or setting
the appropriate environment variable.</p>
<p>The cache has 4 different modes selected by
<code>--vfs-cache-mode</code>. The higher the cache mode the more
compatible rclone becomes at the cost of using disk space.</p>
<p>Note that files are written back to the remote only when they are
closed and if they haven't been accessed for
<code>--vfs-write-back</code> seconds. If rclone is quit or dies with
files that haven't been uploaded, these will be uploaded next time
rclone is run with the same flags.</p>
<p>If using <code>--vfs-cache-max-size</code> or
<code>--vfs-cache-min-free-space</code> note that the cache may exceed
these quotas for two reasons. Firstly because it is only checked every
<code>--vfs-cache-poll-interval</code>. Secondly because open files
cannot be evicted from the cache. When <code>--vfs-cache-max-size</code>
or <code>--vfs-cache-min-free-space</code> is exceeded, rclone will
attempt to evict the least accessed files from the cache first. rclone
will start with files that haven't been accessed for the longest. This
cache flushing strategy is efficient and more relevant files are likely
to remain cached.</p>
<p>The <code>--vfs-cache-max-age</code> will evict files from the cache
after the set time since last access has passed. The default value of 1
hour will start evicting files from cache that haven't been accessed for
1 hour. When a cached file is accessed the 1 hour timer is reset to 0
and will wait for 1 more hour before evicting. Specify the time with
standard notation, s, m, h, d, w .</p>
<p>You <strong>should not</strong> run two copies of rclone using the
same VFS cache with the same or overlapping remotes if using
<code>--vfs-cache-mode &gt; off</code>. This can potentially cause data
corruption if you do. You can work around this by giving each rclone its
own cache hierarchy with <code>--cache-dir</code>. You don't need to
worry about this if the remotes in use don't overlap.</p>
<h3 id="vfs-cache-mode-off-6">--vfs-cache-mode off</h3>
<p>In this mode (the default) the cache will read directly from the
remote and write directly to the remote without caching anything on
disk.</p>
<p>This will mean some operations are not possible</p>
<ul>
<li>Files can't be opened for both read AND write</li>
<li>Files opened for write can't be seeked</li>
<li>Existing files opened for write must have O_TRUNC set</li>
<li>Files open for read with O_TRUNC will be opened write only</li>
<li>Files open for write only will behave as if O_TRUNC was
supplied</li>
<li>Open modes O_APPEND, O_TRUNC are ignored</li>
<li>If an upload fails it can't be retried</li>
</ul>
<h3 id="vfs-cache-mode-minimal-6">--vfs-cache-mode minimal</h3>
<p>This is very similar to "off" except that files opened for read AND
write will be buffered to disk. This means that files opened for write
will be a lot more compatible, but uses the minimal disk space.</p>
<p>These operations are not possible</p>
<ul>
<li>Files opened for write only can't be seeked</li>
<li>Existing files opened for write must have O_TRUNC set</li>
<li>Files opened for write only will ignore O_APPEND, O_TRUNC</li>
<li>If an upload fails it can't be retried</li>
</ul>
<h3 id="vfs-cache-mode-writes-6">--vfs-cache-mode writes</h3>
<p>In this mode files opened for read only are still read directly from
the remote, write only and read/write files are buffered to disk
first.</p>
<p>This mode should support all normal file system operations.</p>
<p>If an upload fails it will be retried at exponentially increasing
intervals up to 1 minute.</p>
<h3 id="vfs-cache-mode-full-6">--vfs-cache-mode full</h3>
<p>In this mode all reads and writes are buffered to and from disk. When
data is read from the remote this is buffered to disk as well.</p>
<p>In this mode the files in the cache will be sparse files and rclone
will keep track of which bits of the files it has downloaded.</p>
<p>So if an application only reads the starts of each file, then rclone
will only buffer the start of the file. These files will appear to be
their full size in the cache, but they will be sparse files with only
the data that has been downloaded present in them.</p>
<p>This mode should support all normal file system operations and is
otherwise identical to <code>--vfs-cache-mode</code> writes.</p>
<p>When reading a file rclone will read <code>--buffer-size</code> plus
<code>--vfs-read-ahead</code> bytes ahead. The
<code>--buffer-size</code> is buffered in memory whereas the
<code>--vfs-read-ahead</code> is buffered on disk.</p>
<p>When using this mode it is recommended that
<code>--buffer-size</code> is not set too large and
<code>--vfs-read-ahead</code> is set large if required.</p>
<p><strong>IMPORTANT</strong> not all file systems support sparse files.
In particular FAT/exFAT do not. Rclone will perform very badly if the
cache directory is on a filesystem which doesn't support sparse files
and it will log an ERROR message if one is detected.</p>
<h3 id="fingerprinting-6">Fingerprinting</h3>
<p>Various parts of the VFS use fingerprinting to see if a local file
copy has changed relative to a remote file. Fingerprints are made
from:</p>
<ul>
<li>size</li>
<li>modification time</li>
<li>hash</li>
</ul>
<p>where available on an object.</p>
<p>On some backends some of these attributes are slow to read (they take
an extra API call per object, or extra work per object).</p>
<p>For example <code>hash</code> is slow with the <code>local</code> and
<code>sftp</code> backends as they have to read the entire file and hash
it, and <code>modtime</code> is slow with the <code>s3</code>,
<code>swift</code>, <code>ftp</code> and <code>qinqstor</code> backends
because they need to do an extra API call to fetch it.</p>
<p>If you use the <code>--vfs-fast-fingerprint</code> flag then rclone
will not include the slow operations in the fingerprint. This makes the
fingerprinting less accurate but much faster and will improve the
opening time of cached files.</p>
<p>If you are running a vfs cache over <code>local</code>,
<code>s3</code> or <code>swift</code> backends then using this flag is
recommended.</p>
<p>Note that if you change the value of this flag, the fingerprints of
the files in the cache may be invalidated and the files will need to be
downloaded again.</p>
<h2 id="vfs-chunked-reading-6">VFS Chunked Reading</h2>
<p>When rclone reads files from a remote it reads them in chunks. This
means that rather than requesting the whole file rclone reads the chunk
specified. This can reduce the used download quota for some remotes by
requesting only chunks from the remote that are actually read, at the
cost of an increased number of requests.</p>
<p>These flags control the chunking:</p>
<pre class="text"><code>    --vfs-read-chunk-size SizeSuffix        Read the source objects in chunks (default 128M)
    --vfs-read-chunk-size-limit SizeSuffix  Max chunk doubling size (default off)
    --vfs-read-chunk-streams int            The number of parallel streams to read at once</code></pre>
<p>The chunking behaves differently depending on the
<code>--vfs-read-chunk-streams</code> parameter.</p>
<h3
id="vfs-read-chunk-streams-0-12"><code>--vfs-read-chunk-streams</code>
== 0</h3>
<p>Rclone will start reading a chunk of size
<code>--vfs-read-chunk-size</code>, and then double the size for each
read. When <code>--vfs-read-chunk-size-limit</code> is specified, and
greater than <code>--vfs-read-chunk-size</code>, the chunk size for each
open file will get doubled only until the specified value is reached. If
the value is "off", which is the default, the limit is disabled and the
chunk size will grow indefinitely.</p>
<p>With <code>--vfs-read-chunk-size 100M</code> and
<code>--vfs-read-chunk-size-limit 0</code> the following parts will be
downloaded: 0-100M, 100M-200M, 200M-300M, 300M-400M and so on. When
<code>--vfs-read-chunk-size-limit 500M</code> is specified, the result
would be 0-100M, 100M-300M, 300M-700M, 700M-1200M, 1200M-1700M and so
on.</p>
<p>Setting <code>--vfs-read-chunk-size</code> to <code>0</code> or "off"
disables chunked reading.</p>
<p>The chunks will not be buffered in memory.</p>
<h3
id="vfs-read-chunk-streams-0-13"><code>--vfs-read-chunk-streams</code>
&gt; 0</h3>
<p>Rclone reads <code>--vfs-read-chunk-streams</code> chunks of size
<code>--vfs-read-chunk-size</code> concurrently. The size for each read
will stay constant.</p>
<p>This improves performance performance massively on high latency links
or very high bandwidth links to high performance object stores.</p>
<p>Some experimentation will be needed to find the optimum values of
<code>--vfs-read-chunk-size</code> and
<code>--vfs-read-chunk-streams</code> as these will depend on the
backend in use and the latency to the backend.</p>
<p>For high performance object stores (eg AWS S3) a reasonable place to
start might be <code>--vfs-read-chunk-streams 16</code> and
<code>--vfs-read-chunk-size 4M</code>. In testing with AWS S3 the
performance scaled roughly as the <code>--vfs-read-chunk-streams</code>
setting.</p>
<p>Similar settings should work for high latency links, but depending on
the latency they may need more <code>--vfs-read-chunk-streams</code> in
order to get the throughput.</p>
<h2 id="vfs-performance-6">VFS Performance</h2>
<p>These flags may be used to enable/disable features of the VFS for
performance or other reasons. See also the <a
href="#vfs-chunked-reading">chunked reading</a> feature.</p>
<p>In particular S3 and Swift benefit hugely from the
<code>--no-modtime</code> flag (or use <code>--use-server-modtime</code>
for a slightly different effect) as each read of the modification time
takes a transaction.</p>
<pre class="text"><code>    --no-checksum     Don&#39;t compare checksums on up/download.
    --no-modtime      Don&#39;t read/write the modification time (can speed things up).
    --no-seek         Don&#39;t allow seeking in files.
    --read-only       Only allow read-only access.</code></pre>
<p>Sometimes rclone is delivered reads or writes out of order. Rather
than seeking rclone will wait a short time for the in sequence read or
write to come in. These flags only come into effect when not using an on
disk cache file.</p>
<pre class="text"><code>    --vfs-read-wait duration   Time to wait for in-sequence read before seeking (default 20ms)
    --vfs-write-wait duration  Time to wait for in-sequence write before giving error (default 1s)</code></pre>
<p>When using VFS write caching (<code>--vfs-cache-mode</code> with
value writes or full), the global flag <code>--transfers</code> can be
set to adjust the number of parallel uploads of modified files from the
cache (the related global flag <code>--checkers</code> has no effect on
the VFS).</p>
<pre class="text"><code>    --transfers int  Number of file transfers to run in parallel (default 4)</code></pre>
<h2 id="symlinks-6">Symlinks</h2>
<p>By default the VFS does not support symlinks. However this may be
enabled with either of the following flags:</p>
<pre class="text"><code>    --links      Translate symlinks to/from regular files with a &#39;.rclonelink&#39; extension.
    --vfs-links  Translate symlinks to/from regular files with a &#39;.rclonelink&#39; extension for the VFS</code></pre>
<p>As most cloud storage systems do not support symlinks directly,
rclone stores the symlink as a normal file with a special extension. So
a file which appears as a symlink <code>link-to-file.txt</code> would be
stored on cloud storage as <code>link-to-file.txt.rclonelink</code> and
the contents would be the path to the symlink destination.</p>
<p>Note that <code>--links</code> enables symlink translation globally
in rclone - this includes any backend which supports the concept (for
example the local backend). <code>--vfs-links</code> just enables it for
the VFS layer.</p>
<p>This scheme is compatible with that used by the <a
href="https://rclone.org/local/#symlinks-junction-points">local backend
with the --local-links flag</a>.</p>
<p>The <code>--vfs-links</code> flag has been designed for
<code>rclone mount</code>, <code>rclone nfsmount</code> and
<code>rclone serve nfs</code>.</p>
<p>It hasn't been tested with the other <code>rclone serve</code>
commands yet.</p>
<p>A limitation of the current implementation is that it expects the
caller to resolve sub-symlinks. For example given this directory
tree</p>
<pre class="text"><code>.
├── dir
│   └── file.txt
└── linked-dir -&gt; dir</code></pre>
<p>The VFS will correctly resolve <code>linked-dir</code> but not
<code>linked-dir/file.txt</code>. This is not a problem for the tested
commands but may be for other commands.</p>
<p><strong>Note</strong> that there is an outstanding issue with symlink
support <a href="https://github.com/rclone/rclone/issues/8245">issue
#8245</a> with duplicate files being created when symlinks are moved
into directories where there is a file of the same name (or vice
versa).</p>
<h2 id="vfs-case-sensitivity-6">VFS Case Sensitivity</h2>
<p>Linux file systems are case-sensitive: two files can differ only by
case, and the exact case must be used when opening a file.</p>
<p>File systems in modern Windows are case-insensitive but
case-preserving: although existing files can be opened using any case,
the exact case used to create the file is preserved and available for
programs to query. It is not allowed for two files in the same directory
to differ only by case.</p>
<p>Usually file systems on macOS are case-insensitive. It is possible to
make macOS file systems case-sensitive but that is not the default.</p>
<p>The <code>--vfs-case-insensitive</code> VFS flag controls how rclone
handles these two cases. If its value is "false", rclone passes file
names to the remote as-is. If the flag is "true" (or appears without a
value on the command line), rclone may perform a "fixup" as explained
below.</p>
<p>The user may specify a file name to open/delete/rename/etc with a
case different than what is stored on the remote. If an argument refers
to an existing file with exactly the same name, then the case of the
existing file on the disk will be used. However, if a file name with
exactly the same name is not found but a name differing only by case
exists, rclone will transparently fixup the name. This fixup happens
only when an existing file is requested. Case sensitivity of file names
created anew by rclone is controlled by the underlying remote.</p>
<p>Note that case sensitivity of the operating system running rclone
(the target) may differ from case sensitivity of a file system presented
by rclone (the source). The flag controls whether "fixup" is performed
to satisfy the target.</p>
<p>If the flag is not provided on the command line, then its default
value depends on the operating system where rclone runs: "true" on
Windows and macOS, "false" otherwise. If the flag is provided without a
value, then it is "true".</p>
<p>The <code>--no-unicode-normalization</code> flag controls whether a
similar "fixup" is performed for filenames that differ but are <a
href="https://en.wikipedia.org/wiki/Unicode_equivalence">canonically
equivalent</a> with respect to unicode. Unicode normalization can be
particularly helpful for users of macOS, which prefers form NFD instead
of the NFC used by most other platforms. It is therefore highly
recommended to keep the default of <code>false</code> on macOS, to avoid
encoding compatibility issues.</p>
<p>In the (probably unlikely) event that a directory has multiple
duplicate filenames after applying case and unicode normalization, the
<code>--vfs-block-norm-dupes</code> flag allows hiding these duplicates.
This comes with a performance tradeoff, as rclone will have to scan the
entire directory for duplicates when listing a directory. For this
reason, it is recommended to leave this disabled if not needed. However,
macOS users may wish to consider using it, as otherwise, if a remote
directory contains both NFC and NFD versions of the same filename, an
odd situation will occur: both versions of the file will be visible in
the mount, and both will appear to be editable, however, editing either
version will actually result in only the NFD version getting edited
under the hood. <code>--vfs-block- norm-dupes</code> prevents this
confusion by detecting this scenario, hiding the duplicates, and logging
an error, similar to how this is handled in
<code>rclone sync</code>.</p>
<h2 id="vfs-disk-options-6">VFS Disk Options</h2>
<p>This flag allows you to manually set the statistics about the filing
system. It can be useful when those statistics cannot be read correctly
automatically.</p>
<pre class="text"><code>    --vfs-disk-space-total-size    Manually set the total disk space size (example: 256G, default: -1)</code></pre>
<h2 id="alternate-report-of-used-bytes-6">Alternate report of used
bytes</h2>
<p>Some backends, most notably S3, do not report the amount of bytes
used. If you need this information to be available when running
<code>df</code> on the filesystem, then pass the flag
<code>--vfs-used-is-size</code> to rclone. With this flag set, instead
of relying on the backend to report this information, rclone will scan
the whole remote similar to <code>rclone size</code> and compute the
total used space itself.</p>
<p><strong>WARNING</strong>: Contrary to <code>rclone size</code>, this
flag ignores filters so that the result is accurate. However, this is
very inefficient and may cost lots of API calls resulting in extra
charges. Use it as a last resort and only with caching.</p>
<h2 id="vfs-metadata-6">VFS Metadata</h2>
<p>If you use the <code>--vfs-metadata-extension</code> flag you can get
the VFS to expose files which contain the <a
href="https://rclone.org/docs/#metadata">metadata</a> as a JSON blob.
These files will not appear in the directory listing, but can be
<code>stat</code>-ed and opened and once they have been they
<strong>will</strong> appear in directory listings until the directory
cache expires.</p>
<p>Note that some backends won't create metadata unless you pass in the
<code>--metadata</code> flag.</p>
<p>For example, using <code>rclone mount</code> with

<h1 id="rclone-serve-restic">rclone serve restic</h1>
<p>Serve the remote for restic's REST API.</p>
<h2 id="synopsis-75">Synopsis</h2>
<p>Run a basic web server to serve a remote over restic's REST backend
API over HTTP. This allows restic to use rclone as a data storage
mechanism for cloud providers that restic does not support directly.</p>
<p><a href="https://restic.net/">Restic</a> is a command-line program
for doing backups.</p>
<p>The server will log errors. Use -v to see access logs.</p>
<p><code>--bwlimit</code> will be respected for file transfers. Use
<code>--stats</code> to control the stats printing.</p>
<h2 id="setting-up-rclone-for-use-by-restic">Setting up rclone for use
by restic</h2>
<p>First <a href="https://rclone.org/docs/#configure">set up a remote
for your chosen cloud provider</a>.</p>
<p>Once you have set up the remote, check it is working with, for
example "rclone lsd remote:". You may have called the remote something
other than "remote:" - just substitute whatever you called it in the
following instructions.</p>
<p>Now start the rclone restic server</p>
<pre class="console"><code>rclone serve restic -v remote:backup</code></pre>
<p>Where you can replace "backup" in the above by whatever path in the
remote you wish to use.</p>
<p>By default this will serve on "localhost:8080" you can change this
with use of the <code>--addr</code> flag.</p>
<p>You might wish to start this server on boot.</p>
<p>Adding <code>--cache-objects=false</code> will cause rclone to stop
caching objects returned from the List call. Caching is normally
desirable as it speeds up downloading objects, saves transactions and
uses very little memory.</p>
<h2 id="setting-up-restic-to-use-rclone">Setting up restic to use
rclone</h2>
<p>Now you can <a
href="http://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html#rest-server">follow
the restic instructions</a> on setting up restic.</p>
<p>Note that you will need restic 0.8.2 or later to interoperate with
rclone.</p>
<p>For the example above you will want to use "http://localhost:8080/"
as the URL for the REST server.</p>
<p>For example:</p>
<pre class="console"><code>$ export RESTIC_REPOSITORY=rest:http://localhost:8080/
$ export RESTIC_PASSWORD=yourpassword
$ restic init
created restic backend 8b1a4b56ae at rest:http://localhost:8080/

Please note that knowledge of your password is required to access
the repository. Losing your password means that your data is
irrecoverably lost.
$ restic backup /path/to/files/to/backup
scan [/path/to/files/to/backup]
scanned 189 directories, 312 files in 0:00
[0:00] 100.00%  38.128 MiB / 38.128 MiB  501 / 501 items  0 errors  ETA 0:00
duration: 0:00
snapshot 45c8fdd8 saved
</code></pre>
<h3 id="multiple-repositories">Multiple repositories</h3>
<p>Note that you can use the endpoint to host multiple repositories. Do
this by adding a directory name or path after the URL. Note that these
<strong>must</strong> end with /. Eg</p>
<pre class="console"><code>$ export RESTIC_REPOSITORY=rest:http://localhost:8080/user1repo/
# backup user1 stuff
$ export RESTIC_REPOSITORY=rest:http://localhost:8080/user2repo/
# backup user2 stuff</code></pre>
<h3 id="private-repositories">Private repositories</h3>
<p>The<code>--private-repos</code> flag can be used to limit users to
repositories starting with a path of
<code>/&lt;username&gt;/</code>.</p>
<h2 id="server-options-4">Server options</h2>
<p>Use <code>--addr</code> to specify which IP address and port the
server should listen on, eg <code>--addr 1.2.3.4:8000</code> or
<code>--addr :8080</code> to listen to all IPs. By default it only
listens on localhost. You can use port :0 to let the OS choose an
available port.</p>
<p>If you set <code>--addr</code> to listen on a public or LAN
accessible IP address then using Authentication is advised - see the
next section for info.</p>
<p>You can use a unix socket by setting the url to
<code>unix:///path/to/socket</code> or just by using an absolute path
name.</p>
<p><code>--addr</code> may be repeated to listen on multiple
IPs/ports/sockets. Socket activation, described further below, can also
be used to accomplish the same.</p>
<p><code>--server-read-timeout</code> and
<code>--server-write-timeout</code> can be used to control the timeouts
on the server. Note that this is the total time for a transfer.</p>
<p><code>--max-header-bytes</code> controls the maximum number of bytes
the server will accept in the HTTP header.</p>
<p><code>--baseurl</code> controls the URL prefix that rclone serves
from. By default rclone will serve from the root. If you used
<code>--baseurl "/rclone"</code> then rclone would serve from a URL
starting with "/rclone/". This is useful if you wish to proxy rclone
serve. Rclone automatically inserts leading and trailing "/" on
<code>--baseurl</code>, so <code>--baseurl "rclone"</code>,
<code>--baseurl "/rclone"</code> and <code>--baseurl "/rclone/"</code>
are all treated identically.</p>
<p><code>--disable-zip</code> may be set to disable the zipping download
option.</p>
<h3 id="tls-ssl-2">TLS (SSL)</h3>
<p>By default this will serve over http. If you want you can serve over
https. You will need to supply the <code>--cert</code> and
<code>--key</code> flags. If you wish to do client side certificate
validation then you will need to supply <code>--client-ca</code>
also.</p>
<p><code>--cert</code> must be set to the path of a file containing
either a PEM encoded certificate, or a concatenation of that with the CA
certificate. <code>--key</code> must be set to the path of a file with
the PEM encoded private key. If setting <code>--client-ca</code>, it
should be set to the path of a file with PEM encoded client certificate
authority certificates.</p>
<p><code>--min-tls-version</code> is minimum TLS version that is
acceptable. Valid values are "tls1.0", "tls1.1", "tls1.2" and "tls1.3"
(default "tls1.0").</p>
<h2 id="socket-activation-2">Socket activation</h2>
<p>Instead of the listening addresses specified above, rclone will
listen to all FDs passed by the service manager, if any (and ignore any
arguments passed by <code>--addr</code>).</p>
<p>This allows rclone to be a socket-activated service. It can be
configured with .socket and .service unit files as described in <a
href="https://www.freedesktop.org/software/systemd/man/latest/systemd.socket.html"
class="uri">https://www.freedesktop.org/software/systemd/man/latest/systemd.socket.html</a>.</p>
<p>Socket activation can be tested ad-hoc with the
<code>systemd-socket-activate</code>command</p>
<pre class="console"><code>systemd-socket-activate -l 8000 -- rclone serve</code></pre>
<p>This will socket-activate rclone on the first connection to port 8000
over TCP.</p>
<h3 id="authentication-3">Authentication</h3>
<p>By default this will serve files without needing a login.</p>
<p>You can either use an htpasswd file which can take lots of users, or
set a single username and password with the <code>--user</code> and
<code>--pass</code> flags.</p>
<p>Alternatively, you can have the reverse proxy manage authentication
and use the username provided in the configured header with
<code>--user-from-header</code> (e.g.,
<code>--user-from-header=x-remote-user</code>). Ensure the proxy is
trusted and headers cannot be spoofed, as misconfiguration may lead to
unauthorized access.</p>
<p>If either of the above authentication methods is not configured and
client certificates are required by the <code>--client-ca</code> flag
passed to the server, the client certificate common name will be
considered as the username.</p>
<p>Use <code>--htpasswd /path/to/htpasswd</code> to provide an htpasswd
file. This is in standard apache format and supports MD5, SHA1 and
BCrypt for basic authentication. Bcrypt is recommended.</p>
<p>To create an htpasswd file:</p>
<pre class="console"><code>touch htpasswd
htpasswd -B htpasswd user
htpasswd -B htpasswd anotherUser</code></pre>
<p>The password file can be updated while rclone is running.</p>
<p>Use <code>--realm</code> to set the authentication realm.</p>
<p>Use <code>--salt</code> to change the password hashing salt from the
default.</p>

<h1 id="rclone-serve-s3">rclone serve s3</h1>
<p>Serve remote:path over s3.</p>
<h2 id="synopsis-76">Synopsis</h2>
<p><code>serve s3</code> implements a basic s3 server that serves a
remote via s3. This can be viewed with an s3 client, or you can make an
<a href="https://rclone.org/s3/">s3 type remote</a> to read and write to
it with rclone.</p>
<p><code>serve s3</code> is considered <strong>Experimental</strong> so
use with care.</p>
<p>S3 server supports Signature Version 4 authentication. Just use
<code>--auth-key accessKey,secretKey</code> and set the
<code>Authorization</code> header correctly in the request. (See the <a
href="https://docs.aws.amazon.com/general/latest/gr/signature-version-4.html">AWS
docs</a>).</p>
<p><code>--auth-key</code> can be repeated for multiple auth pairs. If
<code>--auth-key</code> is not provided then <code>serve s3</code> will
allow anonymous access.</p>
<p>Please note that some clients may require HTTPS endpoints. See <a
href="#tls-ssl">the SSL docs</a> for more information.</p>
<p>This command uses the <a href="#vfs-virtual-file-system">VFS
directory cache</a>. All the functionality will work with
<code>--vfs-cache-mode off</code>. Using
<code>--vfs-cache-mode full</code> (or <code>writes</code>) can be used
to cache objects locally to improve performance.</p>
<p>Use <code>--force-path-style=false</code> if you want to use the
bucket name as a part of the hostname (such as mybucket.local)</p>
<p>Use <code>--etag-hash</code> if you want to change the hash uses for
the <code>ETag</code>. Note that using anything other than
<code>MD5</code> (the default) is likely to cause problems for S3
clients which rely on the Etag being the MD5.</p>
<h2 id="quickstart-1">Quickstart</h2>
<p>For a simple set up, to serve <code>remote:path</code> over s3, run
the server like this:</p>
<pre class="console"><code>rclone serve s3 --auth-key ACCESS_KEY_ID,SECRET_ACCESS_KEY remote:path</code></pre>
<p>For example, to use a simple folder in the filesystem, run the server
with a command like this:</p>
<pre class="console"><code>rclone serve s3 --auth-key ACCESS_KEY_ID,SECRET_ACCESS_KEY local:/path/to/folder</code></pre>
<p>The <code>rclone.conf</code> for the server could look like this:</p>
<div class="sourceCode" id="cb540"><pre
class="sourceCode ini"><code class="sourceCode ini"><span id="cb540-1"><a href="#cb540-1" aria-hidden="true" tabindex="-1"></a><span class="kw">[local]</span></span>
<span id="cb540-2"><a href="#cb540-2" aria-hidden="true" tabindex="-1"></a><span class="dt">type </span><span class="ot">=</span><span class="st"> local</span></span></code></pre></div>
<p>The <code>local</code> configuration is optional though. If you run
the server with a <code>remote:path</code> like
<code>/path/to/folder</code> (without the <code>local:</code> prefix and
without an <code>rclone.conf</code> file), rclone will fall back to a
default configuration, which will be visible as a warning in the logs.
But it will run nonetheless.</p>
<p>This will be compatible with an rclone (client) remote configuration
which is defined like this:</p>
<div class="sourceCode" id="cb541"><pre
class="sourceCode ini"><code class="sourceCode ini"><span id="cb541-1"><a href="#cb541-1" aria-hidden="true" tabindex="-1"></a><span class="kw">[serves3]</span></span>

<p>Note that setting <code>use_multipart_uploads = false</code> is to
work around <a href="#bugs">a bug</a> which will be fixed in due
course.</p>
<h2 id="bugs">Bugs</h2>
<p>When uploading multipart files <code>serve s3</code> holds all the
parts in memory (see <a
href="https://github.com/rclone/rclone/issues/7453">#7453</a>). This is
a limitaton of the library rclone uses for serving S3 and will hopefully
be fixed at some point.</p>
<p>Multipart server side copies do not work (see <a
href="https://github.com/rclone/rclone/issues/7454">#7454</a>). These
take a very long time and eventually fail. The default threshold for
multipart server side copies is 5G which is the maximum it can be, so
files above this side will fail to be server side copied.</p>
<p>For a current list of <code>serve s3</code> bugs see the <a
href="https://github.com/rclone/rclone/labels/serve%20s3">serve s3</a>
bug category on GitHub.</p>
<h2 id="limitations-2">Limitations</h2>
<p><code>serve s3</code> will treat all directories in the root as
buckets and ignore all files in the root. You can use
<code>CreateBucket</code> to create folders under the root, but you
can't create empty folders under other folders not in the root.</p>
<p>When using <code>PutObject</code> or <code>DeleteObject</code>,
rclone will automatically create or clean up empty folders. If you don't
want to clean up empty folders automatically, use
<code>--no-cleanup</code>.</p>
<p>When using <code>ListObjects</code>, rclone will use <code>/</code>
when the delimiter is empty. This reduces backend requests with no
effect on most operations, but if the delimiter is something other than
<code>/</code> and empty, rclone will do a full recursive search of the
backend, which can take some time.</p>
<p>Versioning is not currently supported.</p>
<p>Metadata will only be saved in memory other than the rclone
<code>mtime</code> metadata which will be set as the modification time
of the file.</p>
<h2 id="supported-operations">Supported operations</h2>
<p><code>serve s3</code> currently supports the following
operations.</p>
<ul>
<li>Bucket
<ul>
<li><code>ListBuckets</code></li>
<li><code>CreateBucket</code></li>
<li><code>DeleteBucket</code></li>
</ul></li>
<li>Object

<li><code>CompleteMultipartUpload</code></li>
<li><code>AbortMultipartUpload</code></li>
<li><code>CopyObject</code></li>
<li><code>UploadPart</code></li>
</ul></li>
</ul>
<p>Other operations will return error <code>Unimplemented</code>.</p>
<h3 id="authentication-4">Authentication</h3>
<p>By default this will serve files without needing a login.</p>
<p>You can either use an htpasswd file which can take lots of users, or
set a single username and password with the <code>--user</code> and
<code>--pass</code> flags.</p>
<p>Alternatively, you can have the reverse proxy manage authentication
and use the username provided in the configured header with
<code>--user-from-header</code> (e.g.,
<code>--user-from-header=x-remote-user</code>). Ensure the proxy is
trusted and headers cannot be spoofed, as misconfiguration may lead to
unauthorized access.</p>
<p>If either of the above authentication methods is not configured and
client certificates are required by the <code>--client-ca</code> flag
passed to the server, the client certificate common name will be
considered as the username.</p>
<p>Use <code>--htpasswd /path/to/htpasswd</code> to provide an htpasswd
file. This is in standard apache format and supports MD5, SHA1 and
BCrypt for basic authentication. Bcrypt is recommended.</p>
<p>To create an htpasswd file:</p>
<pre class="console"><code>touch htpasswd
htpasswd -B htpasswd user
htpasswd -B htpasswd anotherUser</code></pre>
<p>The password file can be updated while rclone is running.</p>
<p>Use <code>--realm</code> to set the authentication realm.</p>
<p>Use <code>--salt</code> to change the password hashing salt from the
default.</p>
<h2 id="server-options-5">Server options</h2>
<p>Use <code>--addr</code> to specify which IP address and port the
server should listen on, eg <code>--addr 1.2.3.4:8000</code> or
<code>--addr :8080</code> to listen to all IPs. By default it only
listens on localhost. You can use port :0 to let the OS choose an
available port.</p>
<p>If you set <code>--addr</code> to listen on a public or LAN
accessible IP address then using Authentication is advised - see the
next section for info.</p>
<p>You can use a unix socket by setting the url to
<code>unix:///path/to/socket</code> or just by using an absolute path
name.</p>
<p><code>--addr</code> may be repeated to listen on multiple
IPs/ports/sockets. Socket activation, described further below, can also
be used to accomplish the same.</p>
<p><code>--server-read-timeout</code> and
<code>--server-write-timeout</code> can be used to control the timeouts
on the server. Note that this is the total time for a transfer.</p>
<p><code>--max-header-bytes</code> controls the maximum number of bytes
the server will accept in the HTTP header.</p>
<p><code>--baseurl</code> controls the URL prefix that rclone serves
from. By default rclone will serve from the root. If you used
<code>--baseurl "/rclone"</code> then rclone would serve from a URL
starting with "/rclone/". This is useful if you wish to proxy rclone
serve. Rclone automatically inserts leading and trailing "/" on
<code>--baseurl</code>, so <code>--baseurl "rclone"</code>,
<code>--baseurl "/rclone"</code> and <code>--baseurl "/rclone/"</code>
are all treated identically.</p>
<p><code>--disable-zip</code> may be set to disable the zipping download
option.</p>
<h3 id="tls-ssl-3">TLS (SSL)</h3>
<p>By default this will serve over http. If you want you can serve over
https. You will need to supply the <code>--cert</code> and
<code>--key</code> flags. If you wish to do client side certificate
validation then you will need to supply <code>--client-ca</code>
also.</p>
<p><code>--cert</code> must be set to the path of a file containing
either a PEM encoded certificate, or a concatenation of that with the CA
certificate. <code>--key</code> must be set to the path of a file with
the PEM encoded private key. If setting <code>--client-ca</code>, it
should be set to the path of a file with PEM encoded client certificate
authority certificates.</p>
<p><code>--min-tls-version</code> is minimum TLS version that is
acceptable. Valid values are "tls1.0", "tls1.1", "tls1.2" and "tls1.3"
(default "tls1.0").</p>
<h2 id="socket-activation-3">Socket activation</h2>
<p>Instead of the listening addresses specified above, rclone will
listen to all FDs passed by the service manager, if any (and ignore any
arguments passed by <code>--addr</code>).</p>
<p>This allows rclone to be a socket-activated service. It can be
configured with .socket and .service unit files as described in <a
href="https://www.freedesktop.org/software/systemd/man/latest/systemd.socket.html"
class="uri">https://www.freedesktop.org/software/systemd/man/latest/systemd.socket.html</a>.</p>
<p>Socket activation can be tested ad-hoc with the
<code>systemd-socket-activate</code>command</p>
<pre class="console"><code>systemd-socket-activate -l 8000 -- rclone serve</code></pre>
<p>This will socket-activate rclone on the first connection to port 8000
over TCP.</p>
<h2 id="vfs---virtual-file-system-7">VFS - Virtual File System</h2>
<p>This command uses the VFS layer. This adapts the cloud storage
objects that rclone uses into something which looks much more like a
disk filing system.</p>
<p>Cloud storage objects have lots of properties which aren't like disk
files - you can't extend them or write to the middle of them, so the VFS
layer has to deal with that. Because there is no one right way of doing
this there are various options explained below.</p>
<p>The VFS layer also implements a directory cache - this caches info
about files and directories (but not the data) in memory.</p>
<h2 id="vfs-directory-cache-7">VFS Directory Cache</h2>
<p>Using the <code>--dir-cache-time</code> flag, you can control how
long a directory should be considered up to date and not refreshed from
the backend. Changes made through the VFS will appear immediately or
invalidate the cache.</p>
<pre class="text"><code>    --dir-cache-time duration   Time to cache directory entries for (default 5m0s)
    --poll-interval duration    Time to wait between polling for changes. Must be smaller than dir-cache-time. Only on supported remotes. Set to 0 to disable (default 1m0s)</code></pre>
<p>However, changes made directly on the cloud storage by the web
interface or a different copy of rclone will only be picked up once the
directory cache expires if the backend configured does not support
polling for changes. If the backend supports polling, changes will be
picked up within the polling interval.</p>
<p>You can send a <code>SIGHUP</code> signal to rclone for it to flush
all directory caches, regardless of how old they are. Assuming only one
rclone instance is running, you can reset the cache like this:</p>
<pre class="console"><code>kill -SIGHUP $(pidof rclone)</code></pre>
<p>If you configure rclone with a <a href="/rc">remote control</a> then
you can use rclone rc to flush the whole directory cache:</p>
<pre class="console"><code>rclone rc vfs/forget</code></pre>
<p>Or individual files or directories:</p>
<pre class="console"><code>rclone rc vfs/forget file=path/to/file dir=path/to/dir</code></pre>
<h2 id="vfs-file-buffering-7">VFS File Buffering</h2>
<p>The <code>--buffer-size</code> flag determines the amount of memory,
that will be used to buffer data in advance.</p>
<p>Each open file will try to keep the specified amount of data in
memory at all times. The buffered data is bound to one open file and
won't be shared.</p>
<p>This flag is a upper limit for the used memory per open file. The
buffer will only use memory for data that is downloaded but not not yet
read. If the buffer is empty, only a small amount of memory will be
used.</p>
<p>The maximum memory used by rclone for buffering can be up to
<code>--buffer-size * open files</code>.</p>
<h2 id="vfs-file-caching-7">VFS File Caching</h2>
<p>These flags control the VFS file caching options. File caching is
necessary to make the VFS layer appear compatible with a normal file
system. It can be disabled at the cost of some compatibility.</p>
<p>For example you'll need to enable VFS caching if you want to read and
write simultaneously to a file. See below for more details.</p>
<p>Note that the VFS cache is separate from the cache backend and you
may find that you need one or the other or both.</p>
<pre class="text"><code>    --cache-dir string                     Directory rclone will use for caching.
    --vfs-cache-mode CacheMode             Cache mode off|minimal|writes|full (default off)
    --vfs-cache-max-age duration           Max time since last access of objects in the cache (default 1h0m0s)
    --vfs-cache-max-size SizeSuffix        Max total size of objects in the cache (default off)
    --vfs-cache-min-free-space SizeSuffix  Target minimum free space on the disk containing the cache (default off)
    --vfs-cache-poll-interval duration     Interval to poll the cache for stale objects (default 1m0s)
    --vfs-write-back duration              Time to writeback files after last use when using cache (default 5s)</code></pre>
<p>If run with <code>-vv</code> rclone will print the location of the
file cache. The files are stored in the user cache file area which is OS
dependent but can be controlled with <code>--cache-dir</code> or setting
the appropriate environment variable.</p>
<p>The cache has 4 different modes selected by
<code>--vfs-cache-mode</code>. The higher the cache mode the more
compatible rclone becomes at the cost of using disk space.</p>
<p>Note that files are written back to the remote only when they are
closed and if they haven't been accessed for
<code>--vfs-write-back</code> seconds. If rclone is quit or dies with
files that haven't been uploaded, these will be uploaded next time
rclone is run with the same flags.</p>
<p>If using <code>--vfs-cache-max-size</code> or
<code>--vfs-cache-min-free-space</code> note that the cache may exceed
these quotas for two reasons. Firstly because it is only checked every
<code>--vfs-cache-poll-interval</code>. Secondly because open files
cannot be evicted from the cache. When <code>--vfs-cache-max-size</code>
or <code>--vfs-cache-min-free-space</code> is exceeded, rclone will
attempt to evict the least accessed files from the cache first. rclone
will start with files that haven't been accessed for the longest. This
cache flushing strategy is efficient and more relevant files are likely
to remain cached.</p>
<p>The <code>--vfs-cache-max-age</code> will evict files from the cache
after the set time since last access has passed. The default value of 1
hour will start evicting files from cache that haven't been accessed for
1 hour. When a cached file is accessed the 1 hour timer is reset to 0
and will wait for 1 more hour before evicting. Specify the time with
standard notation, s, m, h, d, w .</p>
<p>You <strong>should not</strong> run two copies of rclone using the
same VFS cache with the same or overlapping remotes if using
<code>--vfs-cache-mode &gt; off</code>. This can potentially cause data
corruption if you do. You can work around this by giving each rclone its
own cache hierarchy with <code>--cache-dir</code>. You don't need to
worry about this if the remotes in use don't overlap.</p>
<h3 id="vfs-cache-mode-off-7">--vfs-cache-mode off</h3>
<p>In this mode (the default) the cache will read directly from the
remote and write directly to the remote without caching anything on
disk.</p>
<p>This will mean some operations are not possible</p>
<ul>
<li>Files can't be opened for both read AND write</li>
<li>Files opened for write can't be seeked</li>
<li>Existing files opened for write must have O_TRUNC set</li>
<li>Files open for read with O_TRUNC will be opened write only</li>
<li>Files open for write only will behave as if O_TRUNC was
supplied</li>
<li>Open modes O_APPEND, O_TRUNC are ignored</li>
<li>If an upload fails it can't be retried</li>
</ul>
<h3 id="vfs-cache-mode-minimal-7">--vfs-cache-mode minimal</h3>
<p>This is very similar to "off" except that files opened for read AND
write will be buffered to disk. This means that files opened for write
will be a lot more compatible, but uses the minimal disk space.</p>
<p>These operations are not possible</p>
<ul>
<li>Files opened for write only can't be seeked</li>
<li>Existing files opened for write must have O_TRUNC set</li>
<li>Files opened for write only will ignore O_APPEND, O_TRUNC</li>
<li>If an upload fails it can't be retried</li>
</ul>
<h3 id="vfs-cache-mode-writes-7">--vfs-cache-mode writes</h3>
<p>In this mode files opened for read only are still read directly from
the remote, write only and read/write files are buffered to disk
first.</p>
<p>This mode should support all normal file system operations.</p>
<p>If an upload fails it will be retried at exponentially increasing
intervals up to 1 minute.</p>
<h3 id="vfs-cache-mode-full-7">--vfs-cache-mode full</h3>
<p>In this mode all reads and writes are buffered to and from disk. When
data is read from the remote this is buffered to disk as well.</p>
<p>In this mode the files in the cache will be sparse files and rclone
will keep track of which bits of the files it has downloaded.</p>
<p>So if an application only reads the starts of each file, then rclone
will only buffer the start of the file. These files will appear to be
their full size in the cache, but they will be sparse files with only
the data that has been downloaded present in them.</p>
<p>This mode should support all normal file system operations and is
otherwise identical to <code>--vfs-cache-mode</code> writes.</p>
<p>When reading a file rclone will read <code>--buffer-size</code> plus
<code>--vfs-read-ahead</code> bytes ahead. The
<code>--buffer-size</code> is buffered in memory whereas the
<code>--vfs-read-ahead</code> is buffered on disk.</p>
<p>When using this mode it is recommended that
<code>--buffer-size</code> is not set too large and
<code>--vfs-read-ahead</code> is set large if required.</p>
<p><strong>IMPORTANT</strong> not all file systems support sparse files.
In particular FAT/exFAT do not. Rclone will perform very badly if the
cache directory is on a filesystem which doesn't support sparse files
and it will log an ERROR message if one is detected.</p>
<h3 id="fingerprinting-7">Fingerprinting</h3>
<p>Various parts of the VFS use fingerprinting to see if a local file
copy has changed relative to a remote file. Fingerprints are made
from:</p>
<ul>
<li>size</li>
<li>modification time</li>
<li>hash</li>
</ul>
<p>where available on an object.</p>
<p>On some backends some of these attributes are slow to read (they take
an extra API call per object, or extra work per object).</p>
<p>For example <code>hash</code> is slow with the <code>local</code> and
<code>sftp</code> backends as they have to read the entire file and hash
it, and <code>modtime</code> is slow with the <code>s3</code>,
<code>swift</code>, <code>ftp</code> and <code>qinqstor</code> backends
because they need to do an extra API call to fetch it.</p>
<p>If you use the <code>--vfs-fast-fingerprint</code> flag then rclone
will not include the slow operations in the fingerprint. This makes the
fingerprinting less accurate but much faster and will improve the
opening time of cached files.</p>
<p>If you are running a vfs cache over <code>local</code>,
<code>s3</code> or <code>swift</code> backends then using this flag is
recommended.</p>
<p>Note that if you change the value of this flag, the fingerprints of
the files in the cache may be invalidated and the files will need to be
downloaded again.</p>
<h2 id="vfs-chunked-reading-7">VFS Chunked Reading</h2>
<p>When rclone reads files from a remote it reads them in chunks. This
means that rather than requesting the whole file rclone reads the chunk
specified. This can reduce the used download quota for some remotes by
requesting only chunks from the remote that are actually read, at the
cost of an increased number of requests.</p>
<p>These flags control the chunking:</p>
<pre class="text"><code>    --vfs-read-chunk-size SizeSuffix        Read the source objects in chunks (default 128M)
    --vfs-read-chunk-size-limit SizeSuffix  Max chunk doubling size (default off)
    --vfs-read-chunk-streams int            The number of parallel streams to read at once</code></pre>
<p>The chunking behaves differently depending on the
<code>--vfs-read-chunk-streams</code> parameter.</p>
<h3
id="vfs-read-chunk-streams-0-14"><code>--vfs-read-chunk-streams</code>
== 0</h3>
<p>Rclone will start reading a chunk of size
<code>--vfs-read-chunk-size</code>, and then double the size for each
read. When <code>--vfs-read-chunk-size-limit</code> is specified, and
greater than <code>--vfs-read-chunk-size</code>, the chunk size for each
open file will get doubled only until the specified value is reached. If
the value is "off", which is the default, the limit is disabled and the
chunk size will grow indefinitely.</p>
<p>With <code>--vfs-read-chunk-size 100M</code> and
<code>--vfs-read-chunk-size-limit 0</code> the following parts will be
downloaded: 0-100M, 100M-200M, 200M-300M, 300M-400M and so on. When
<code>--vfs-read-chunk-size-limit 500M</code> is specified, the result
would be 0-100M, 100M-300M, 300M-700M, 700M-1200M, 1200M-1700M and so
on.</p>
<p>Setting <code>--vfs-read-chunk-size</code> to <code>0</code> or "off"
disables chunked reading.</p>
<p>The chunks will not be buffered in memory.</p>
<h3
id="vfs-read-chunk-streams-0-15"><code>--vfs-read-chunk-streams</code>
&gt; 0</h3>
<p>Rclone reads <code>--vfs-read-chunk-streams</code> chunks of size
<code>--vfs-read-chunk-size</code> concurrently. The size for each read
will stay constant.</p>
<p>This improves performance performance massively on high latency links
or very high bandwidth links to high performance object stores.</p>
<p>Some experimentation will be needed to find the optimum values of
<code>--vfs-read-chunk-size</code> and
<code>--vfs-read-chunk-streams</code> as these will depend on the
backend in use and the latency to the backend.</p>
<p>For high performance object stores (eg AWS S3) a reasonable place to
start might be <code>--vfs-read-chunk-streams 16</code> and
<code>--vfs-read-chunk-size 4M</code>. In testing with AWS S3 the
performance scaled roughly as the <code>--vfs-read-chunk-streams</code>
setting.</p>
<p>Similar settings should work for high latency links, but depending on
the latency they may need more <code>--vfs-read-chunk-streams</code> in
order to get the throughput.</p>
<h2 id="vfs-performance-7">VFS Performance</h2>
<p>These flags may be used to enable/disable features of the VFS for
performance or other reasons. See also the <a
href="#vfs-chunked-reading">chunked reading</a> feature.</p>
<p>In particular S3 and Swift benefit hugely from the
<code>--no-modtime</code> flag (or use <code>--use-server-modtime</code>
for a slightly different effect) as each read of the modification time
takes a transaction.</p>
<pre class="text"><code>    --no-checksum     Don&#39;t compare checksums on up/download.
    --no-modtime      Don&#39;t read/write the modification time (can speed things up).
    --no-seek         Don&#39;t allow seeking in files.
    --read-only       Only allow read-only access.</code></pre>
<p>Sometimes rclone is delivered reads or writes out of order. Rather
than seeking rclone will wait a short time for the in sequence read or
write to come in. These flags only come into effect when not using an on
disk cache file.</p>
<pre class="text"><code>    --vfs-read-wait duration   Time to wait for in-sequence read before seeking (default 20ms)
    --vfs-write-wait duration  Time to wait for in-sequence write before giving error (default 1s)</code></pre>
<p>When using VFS write caching (<code>--vfs-cache-mode</code> with
value writes or full), the global flag <code>--transfers</code> can be
set to adjust the number of parallel uploads of modified files from the
cache (the related global flag <code>--checkers</code> has no effect on
the VFS).</p>
<pre class="text"><code>    --transfers int  Number of file transfers to run in parallel (default 4)</code></pre>
<h2 id="symlinks-7">Symlinks</h2>
<p>By default the VFS does not support symlinks. However this may be
enabled with either of the following flags:</p>
<pre class="text"><code>    --links      Translate symlinks to/from regular files with a &#39;.rclonelink&#39; extension.
    --vfs-links  Translate symlinks to/from regular files with a &#39;.rclonelink&#39; extension for the VFS</code></pre>
<p>As most cloud storage systems do not support symlinks directly,
rclone stores the symlink as a normal file with a special extension. So
a file which appears as a symlink <code>link-to-file.txt</code> would be
stored on cloud storage as <code>link-to-file.txt.rclonelink</code> and
the contents would be the path to the symlink destination.</p>
<p>Note that <code>--links</code> enables symlink translation globally
in rclone - this includes any backend which supports the concept (for
example the local backend). <code>--vfs-links</code> just enables it for
the VFS layer.</p>
<p>This scheme is compatible with that used by the <a
href="https://rclone.org/local/#symlinks-junction-points">local backend
with the --local-links flag</a>.</p>
<p>The <code>--vfs-links</code> flag has been designed for
<code>rclone mount</code>, <code>rclone nfsmount</code> and
<code>rclone serve nfs</code>.</p>
<p>It hasn't been tested with the other <code>rclone serve</code>
commands yet.</p>
<p>A limitation of the current implementation is that it expects the
caller to resolve sub-symlinks. For example given this directory
tree</p>
<pre class="text"><code>.
├── dir
│   └── file.txt
└── linked-dir -&gt; dir</code></pre>
<p>The VFS will correctly resolve <code>linked-dir</code> but not
<code>linked-dir/file.txt</code>. This is not a problem for the tested
commands but may be for other commands.</p>
<p><strong>Note</strong> that there is an outstanding issue with symlink
support <a href="https://github.com/rclone/rclone/issues/8245">issue
#8245</a> with duplicate files being created when symlinks are moved
into directories where there is a file of the same name (or vice
versa).</p>
<h2 id="vfs-case-sensitivity-7">VFS Case Sensitivity</h2>
<p>Linux file systems are case-sensitive: two files can differ only by
case, and the exact case must be used when opening a file.</p>
<p>File systems in modern Windows are case-insensitive but
case-preserving: although existing files can be opened using any case,
the exact case used to create the file is preserved and available for
programs to query. It is not allowed for two files in the same directory
to differ only by case.</p>
<p>Usually file systems on macOS are case-insensitive. It is possible to
make macOS file systems case-sensitive but that is not the default.</p>
<p>The <code>--vfs-case-insensitive</code> VFS flag controls how rclone
handles these two cases. If its value is "false", rclone passes file
names to the remote as-is. If the flag is "true" (or appears without a
value on the command line), rclone may perform a "fixup" as explained
below.</p>
<p>The user may specify a file name to open/delete/rename/etc with a
case different than what is stored on the remote. If an argument refers
to an existing file with exactly the same name, then the case of the
existing file on the disk will be used. However, if a file name with
exactly the same name is not found but a name differing only by case
exists, rclone will transparently fixup the name. This fixup happens
only when an existing file is requested. Case sensitivity of file names
created anew by rclone is controlled by the underlying remote.</p>
<p>Note that case sensitivity of the operating system running rclone
(the target) may differ from case sensitivity of a file system presented
by rclone (the source). The flag controls whether "fixup" is performed
to satisfy the target.</p>
<p>If the flag is not provided on the command line, then its default
value depends on the operating system where rclone runs: "true" on
Windows and macOS, "false" otherwise. If the flag is provided without a
value, then it is "true".</p>
<p>The <code>--no-unicode-normalization</code> flag controls whether a
similar "fixup" is performed for filenames that differ but are <a
href="https://en.wikipedia.org/wiki/Unicode_equivalence">canonically
equivalent</a> with respect to unicode. Unicode normalization can be
particularly helpful for users of macOS, which prefers form NFD instead
of the NFC used by most other platforms. It is therefore highly
recommended to keep the default of <code>false</code> on macOS, to avoid
encoding compatibility issues.</p>
<p>In the (probably unlikely) event that a directory has multiple
duplicate filenames after applying case and unicode normalization, the
<code>--vfs-block-norm-dupes</code> flag allows hiding these duplicates.
This comes with a performance tradeoff, as rclone will have to scan the
entire directory for duplicates when listing a directory. For this
reason, it is recommended to leave this disabled if not needed. However,
macOS users may wish to consider using it, as otherwise, if a remote
directory contains both NFC and NFD versions of the same filename, an
odd situation will occur: both versions of the file will be visible in
the mount, and both will appear to be editable, however, editing either
version will actually result in only the NFD version getting edited
under the hood. <code>--vfs-block- norm-dupes</code> prevents this
confusion by detecting this scenario, hiding the duplicates, and logging
an error, similar to how this is handled in
<code>rclone sync</code>.</p>
<h2 id="vfs-disk-options-7">VFS Disk Options</h2>
<p>This flag allows you to manually set the statistics about the filing
system. It can be useful when those statistics cannot be read correctly
automatically.</p>
<pre class="text"><code>    --vfs-disk-space-total-size    Manually set the total disk space size (example: 256G, default: -1)</code></pre>
<h2 id="alternate-report-of-used-bytes-7">Alternate report of used
bytes</h2>
<p>Some backends, most notably S3, do not report the amount of bytes
used. If you need this information to be available when running
<code>df</code> on the filesystem, then pass the flag
<code>--vfs-used-is-size</code> to rclone. With this flag set, instead
of relying on the backend to report this information, rclone will scan
the whole remote similar to <code>rclone size</code> and compute the
total used space itself.</p>
<p><strong>WARNING</strong>: Contrary to <code>rclone size</code>, this
flag ignores filters so that the result is accurate. However, this is
very inefficient and may cost lots of API calls resulting in extra
charges. Use it as a last resort and only with caching.</p>
<h2 id="vfs-metadata-7">VFS Metadata</h2>
<p>If you use the <code>--vfs-metadata-extension</code> flag you can get
the VFS to expose files which contain the <a
href="https://rclone.org/docs/#metadata">metadata</a> as a JSON blob.
These files will not appear in the directory listing, but can be
<code>stat</code>-ed and opened and once they have been they
<strong>will</strong> appear in directory listings until the directory
cache expires.</p>
<p>Note that some backends won't create metadata unless you pass in the
<code>--metadata</code> flag.</p>
<p>For example, using <code>rclone mount</code> with
<code>--metadata --vfs-metadata-extension .metadata</code> we get</p>
<pre class="console"><code>$ ls -l /mnt/

<h1 id="rclone-serve-sftp">rclone serve sftp</h1>
<p>Serve the remote over SFTP.</p>
<h2 id="synopsis-77">Synopsis</h2>
<p>Run an SFTP server to serve a remote over SFTP. This can be used with
an SFTP client or you can make a remote of type <a href="/sftp">sftp</a>
to use with it.</p>
<p>You can use the <a href="/filtering">filter</a> flags (e.g.
<code>--include</code>, <code>--exclude</code>) to control what is
served.</p>
<p>The server will respond to a small number of shell commands, mainly
md5sum, sha1sum and df, which enable it to provide support for checksums
and the about feature when accessed from an sftp remote.</p>
<p>Note that this server uses standard 32 KiB packet payload size, which
means you must not configure the client to expect anything else, e.g.
with the <a
href="https://rclone.org/sftp/#sftp-chunk-size">chunk_size</a> option on
an sftp remote.</p>
<p>The server will log errors. Use <code>-v</code> to see access
logs.</p>
<p><code>--bwlimit</code> will be respected for file transfers. Use
<code>--stats</code> to control the stats printing.</p>
<p>You must provide some means of authentication, either with
<code>--user</code>/<code>--pass</code>, an authorized keys file
(specify location with <code>--authorized-keys</code> - the default is
the same as ssh), an <code>--auth-proxy</code>, or set the
<code>--no-auth</code> flag for no authentication when logging in.</p>
<p>If you don't supply a host <code>--key</code> then rclone will
generate rsa, ecdsa and ed25519 variants, and cache them for later use
in rclone's cache directory (see
<code>rclone help flags cache-dir</code>) in the "serve-sftp"
directory.</p>
<p>By default the server binds to localhost:2022 - if you want it to be
reachable externally then supply <code>--addr :2022</code> for
example.</p>
<p>This also supports being run with socket activation, in which case it
will listen on the first passed FD. It can be configured with .socket
and .service unit files as described in <a
href="https://www.freedesktop.org/software/systemd/man/latest/systemd.socket.html"
class="uri">https://www.freedesktop.org/software/systemd/man/latest/systemd.socket.html</a>.</p>
<p>Socket activation can be tested ad-hoc with the
<code>systemd-socket-activate</code>command:</p>
<pre class="console"><code>systemd-socket-activate -l 2222 -- rclone serve sftp :local:vfs/</code></pre>
<p>This will socket-activate rclone on the first connection to port 2222
over TCP.</p>
<p>Note that the default of <code>--vfs-cache-mode off</code> is fine
for the rclone sftp backend, but it may not be with other SFTP
clients.</p>
<p>If <code>--stdio</code> is specified, rclone will serve SFTP over
stdio, which can be used with sshd via ~/.ssh/authorized_keys, for
example:</p>
<pre class="text"><code>restrict,command=&quot;rclone serve sftp --stdio ./photos&quot; ssh-rsa ...</code></pre>
<p>On the client you need to set <code>--transfers 1</code> when using
<code>--stdio</code>. Otherwise multiple instances of the rclone server
are started by OpenSSH which can lead to "corrupted on transfer" errors.
This is the case because the client chooses indiscriminately which
server to send commands to while the servers all have different views of
the state of the filing system.</p>
<p>The "restrict" in authorized_keys prevents SHA1SUMs and MD5SUMs from
being used. Omitting "restrict" and using
<code>--sftp-path-override</code> to enable checksumming is possible but
less secure and you could use the SFTP server provided by OpenSSH in
this case.</p>
<h2 id="vfs---virtual-file-system-8">VFS - Virtual File System</h2>
<p>This command uses the VFS layer. This adapts the cloud storage
objects that rclone uses into something which looks much more like a
disk filing system.</p>
<p>Cloud storage objects have lots of properties which aren't like disk
files - you can't extend them or write to the middle of them, so the VFS
layer has to deal with that. Because there is no one right way of doing
this there are various options explained below.</p>
<p>The VFS layer also implements a directory cache - this caches info
about files and directories (but not the data) in memory.</p>
<h2 id="vfs-directory-cache-8">VFS Directory Cache</h2>
<p>Using the <code>--dir-cache-time</code> flag, you can control how
long a directory should be considered up to date and not refreshed from
the backend. Changes made through the VFS will appear immediately or
invalidate the cache.</p>
<pre class="text"><code>    --dir-cache-time duration   Time to cache directory entries for (default 5m0s)
    --poll-interval duration    Time to wait between polling for changes. Must be smaller than dir-cache-time. Only on supported remotes. Set to 0 to disable (default 1m0s)</code></pre>
<p>However, changes made directly on the cloud storage by the web
interface or a different copy of rclone will only be picked up once the
directory cache expires if the backend configured does not support
polling for changes. If the backend supports polling, changes will be
picked up within the polling interval.</p>
<p>You can send a <code>SIGHUP</code> signal to rclone for it to flush
all directory caches, regardless of how old they are. Assuming only one
rclone instance is running, you can reset the cache like this:</p>
<pre class="console"><code>kill -SIGHUP $(pidof rclone)</code></pre>
<p>If you configure rclone with a <a href="/rc">remote control</a> then
you can use rclone rc to flush the whole directory cache:</p>
<pre class="console"><code>rclone rc vfs/forget</code></pre>
<p>Or individual files or directories:</p>
<pre class="console"><code>rclone rc vfs/forget file=path/to/file dir=path/to/dir</code></pre>
<h2 id="vfs-file-buffering-8">VFS File Buffering</h2>
<p>The <code>--buffer-size</code> flag determines the amount of memory,
that will be used to buffer data in advance.</p>
<p>Each open file will try to keep the specified amount of data in
memory at all times. The buffered data is bound to one open file and
won't be shared.</p>
<p>This flag is a upper limit for the used memory per open file. The
buffer will only use memory for data that is downloaded but not not yet
read. If the buffer is empty, only a small amount of memory will be
used.</p>
<p>The maximum memory used by rclone for buffering can be up to
<code>--buffer-size * open files</code>.</p>
<h2 id="vfs-file-caching-8">VFS File Caching</h2>
<p>These flags control the VFS file caching options. File caching is
necessary to make the VFS layer appear compatible with a normal file
system. It can be disabled at the cost of some compatibility.</p>
<p>For example you'll need to enable VFS caching if you want to read and
write simultaneously to a file. See below for more details.</p>
<p>Note that the VFS cache is separate from the cache backend and you
may find that you need one or the other or both.</p>
<pre class="text"><code>    --cache-dir string                     Directory rclone will use for caching.
    --vfs-cache-mode CacheMode             Cache mode off|minimal|writes|full (default off)
    --vfs-cache-max-age duration           Max time since last access of objects in the cache (default 1h0m0s)
    --vfs-cache-max-size SizeSuffix        Max total size of objects in the cache (default off)
    --vfs-cache-min-free-space SizeSuffix  Target minimum free space on the disk containing the cache (default off)
    --vfs-cache-poll-interval duration     Interval to poll the cache for stale objects (default 1m0s)
    --vfs-write-back duration              Time to writeback files after last use when using cache (default 5s)</code></pre>
<p>If run with <code>-vv</code> rclone will print the location of the
file cache. The files are stored in the user cache file area which is OS
dependent but can be controlled with <code>--cache-dir</code> or setting
the appropriate environment variable.</p>
<p>The cache has 4 different modes selected by
<code>--vfs-cache-mode</code>. The higher the cache mode the more
compatible rclone becomes at the cost of using disk space.</p>
<p>Note that files are written back to the remote only when they are
closed and if they haven't been accessed for
<code>--vfs-write-back</code> seconds. If rclone is quit or dies with
files that haven't been uploaded, these will be uploaded next time
rclone is run with the same flags.</p>
<p>If using <code>--vfs-cache-max-size</code> or
<code>--vfs-cache-min-free-space</code> note that the cache may exceed
these quotas for two reasons. Firstly because it is only checked every
<code>--vfs-cache-poll-interval</code>. Secondly because open files
cannot be evicted from the cache. When <code>--vfs-cache-max-size</code>
or <code>--vfs-cache-min-free-space</code> is exceeded, rclone will
attempt to evict the least accessed files from the cache first. rclone
will start with files that haven't been accessed for the longest. This
cache flushing strategy is efficient and more relevant files are likely
to remain cached.</p>
<p>The <code>--vfs-cache-max-age</code> will evict files from the cache
after the set time since last access has passed. The default value of 1
hour will start evicting files from cache that haven't been accessed for
1 hour. When a cached file is accessed the 1 hour timer is reset to 0
and will wait for 1 more hour before evicting. Specify the time with
standard notation, s, m, h, d, w .</p>
<p>You <strong>should not</strong> run two copies of rclone using the
same VFS cache with the same or overlapping remotes if using
<code>--vfs-cache-mode &gt; off</code>. This can potentially cause data
corruption if you do. You can work around this by giving each rclone its
own cache hierarchy with <code>--cache-dir</code>. You don't need to
worry about this if the remotes in use don't overlap.</p>
<h3 id="vfs-cache-mode-off-8">--vfs-cache-mode off</h3>
<p>In this mode (the default) the cache will read directly from the
remote and write directly to the remote without caching anything on
disk.</p>
<p>This will mean some operations are not possible</p>
<ul>
<li>Files can't be opened for both read AND write</li>
<li>Files opened for write can't be seeked</li>
<li>Existing files opened for write must have O_TRUNC set</li>
<li>Files open for read with O_TRUNC will be opened write only</li>
<li>Files open for write only will behave as if O_TRUNC was
supplied</li>
<li>Open modes O_APPEND, O_TRUNC are ignored</li>
<li>If an upload fails it can't be retried</li>
</ul>
<h3 id="vfs-cache-mode-minimal-8">--vfs-cache-mode minimal</h3>
<p>This is very similar to "off" except that files opened for read AND
write will be buffered to disk. This means that files opened for write
will be a lot more compatible, but uses the minimal disk space.</p>
<p>These operations are not possible</p>
<ul>
<li>Files opened for write only can't be seeked</li>
<li>Existing files opened for write must have O_TRUNC set</li>
<li>Files opened for write only will ignore O_APPEND, O_TRUNC</li>
<li>If an upload fails it can't be retried</li>
</ul>
<h3 id="vfs-cache-mode-writes-8">--vfs-cache-mode writes</h3>
<p>In this mode files opened for read only are still read directly from
the remote, write only and read/write files are buffered to disk
first.</p>
<p>This mode should support all normal file system operations.</p>
<p>If an upload fails it will be retried at exponentially increasing
intervals up to 1 minute.</p>
<h3 id="vfs-cache-mode-full-8">--vfs-cache-mode full</h3>
<p>In this mode all reads and writes are buffered to and from disk. When
data is read from the remote this is buffered to disk as well.</p>
<p>In this mode the files in the cache will be sparse files and rclone
will keep track of which bits of the files it has downloaded.</p>
<p>So if an application only reads the starts of each file, then rclone
will only buffer the start of the file. These files will appear to be
their full size in the cache, but they will be sparse files with only
the data that has been downloaded present in them.</p>
<p>This mode should support all normal file system operations and is
otherwise identical to <code>--vfs-cache-mode</code> writes.</p>
<p>When reading a file rclone will read <code>--buffer-size</code> plus
<code>--vfs-read-ahead</code> bytes ahead. The
<code>--buffer-size</code> is buffered in memory whereas the
<code>--vfs-read-ahead</code> is buffered on disk.</p>
<p>When using this mode it is recommended that
<code>--buffer-size</code> is not set too large and
<code>--vfs-read-ahead</code> is set large if required.</p>
<p><strong>IMPORTANT</strong> not all file systems support sparse files.
In particular FAT/exFAT do not. Rclone will perform very badly if the
cache directory is on a filesystem which doesn't support sparse files
and it will log an ERROR message if one is detected.</p>
<h3 id="fingerprinting-8">Fingerprinting</h3>
<p>Various parts of the VFS use fingerprinting to see if a local file
copy has changed relative to a remote file. Fingerprints are made
from:</p>
<ul>
<li>size</li>
<li>modification time</li>
<li>hash</li>
</ul>
<p>where available on an object.</p>
<p>On some backends some of these attributes are slow to read (they take
an extra API call per object, or extra work per object).</p>
<p>For example <code>hash</code> is slow with the <code>local</code> and
<code>sftp</code> backends as they have to read the entire file and hash
it, and <code>modtime</code> is slow with the <code>s3</code>,
<code>swift</code>, <code>ftp</code> and <code>qinqstor</code> backends
because they need to do an extra API call to fetch it.</p>
<p>If you use the <code>--vfs-fast-fingerprint</code> flag then rclone
will not include the slow operations in the fingerprint. This makes the
fingerprinting less accurate but much faster and will improve the
opening time of cached files.</p>
<p>If you are running a vfs cache over <code>local</code>,
<code>s3</code> or <code>swift</code> backends then using this flag is
recommended.</p>
<p>Note that if you change the value of this flag, the fingerprints of
the files in the cache may be invalidated and the files will need to be
downloaded again.</p>
<h2 id="vfs-chunked-reading-8">VFS Chunked Reading</h2>
<p>When rclone reads files from a remote it reads them in chunks. This
means that rather than requesting the whole file rclone reads the chunk
specified. This can reduce the used download quota for some remotes by
requesting only chunks from the remote that are actually read, at the
cost of an increased number of requests.</p>
<p>These flags control the chunking:</p>
<pre class="text"><code>    --vfs-read-chunk-size SizeSuffix        Read the source objects in chunks (default 128M)
    --vfs-read-chunk-size-limit SizeSuffix  Max chunk doubling size (default off)
    --vfs-read-chunk-streams int            The number of parallel streams to read at once</code></pre>
<p>The chunking behaves differently depending on the
<code>--vfs-read-chunk-streams</code> parameter.</p>
<h3
id="vfs-read-chunk-streams-0-16"><code>--vfs-read-chunk-streams</code>
== 0</h3>
<p>Rclone will start reading a chunk of size
<code>--vfs-read-chunk-size</code>, and then double the size for each
read. When <code>--vfs-read-chunk-size-limit</code> is specified, and
greater than <code>--vfs-read-chunk-size</code>, the chunk size for each
open file will get doubled only until the specified value is reached. If
the value is "off", which is the default, the limit is disabled and the
chunk size will grow indefinitely.</p>
<p>With <code>--vfs-read-chunk-size 100M</code> and
<code>--vfs-read-chunk-size-limit 0</code> the following parts will be
downloaded: 0-100M, 100M-200M, 200M-300M, 300M-400M and so on. When
<code>--vfs-read-chunk-size-limit 500M</code> is specified, the result
would be 0-100M, 100M-300M, 300M-700M, 700M-1200M, 1200M-1700M and so
on.</p>
<p>Setting <code>--vfs-read-chunk-size</code> to <code>0</code> or "off"
disables chunked reading.</p>
<p>The chunks will not be buffered in memory.</p>
<h3
id="vfs-read-chunk-streams-0-17"><code>--vfs-read-chunk-streams</code>
&gt; 0</h3>
<p>Rclone reads <code>--vfs-read-chunk-streams</code> chunks of size
<code>--vfs-read-chunk-size</code> concurrently. The size for each read
will stay constant.</p>
<p>This improves performance performance massively on high latency links
or very high bandwidth links to high performance object stores.</p>
<p>Some experimentation will be needed to find the optimum values of
<code>--vfs-read-chunk-size</code> and
<code>--vfs-read-chunk-streams</code> as these will depend on the
backend in use and the latency to the backend.</p>
<p>For high performance object stores (eg AWS S3) a reasonable place to
start might be <code>--vfs-read-chunk-streams 16</code> and
<code>--vfs-read-chunk-size 4M</code>. In testing with AWS S3 the
performance scaled roughly as the <code>--vfs-read-chunk-streams</code>
setting.</p>
<p>Similar settings should work for high latency links, but depending on
the latency they may need more <code>--vfs-read-chunk-streams</code> in
order to get the throughput.</p>
<h2 id="vfs-performance-8">VFS Performance</h2>
<p>These flags may be used to enable/disable features of the VFS for
performance or other reasons. See also the <a
href="#vfs-chunked-reading">chunked reading</a> feature.</p>
<p>In particular S3 and Swift benefit hugely from the
<code>--no-modtime</code> flag (or use <code>--use-server-modtime</code>
for a slightly different effect) as each read of the modification time
takes a transaction.</p>
<pre class="text"><code>    --no-checksum     Don&#39;t compare checksums on up/download.
    --no-modtime      Don&#39;t read/write the modification time (can speed things up).
    --no-seek         Don&#39;t allow seeking in files.
    --read-only       Only allow read-only access.</code></pre>
<p>Sometimes rclone is delivered reads or writes out of order. Rather
than seeking rclone will wait a short time for the in sequence read or
write to come in. These flags only come into effect when not using an on
disk cache file.</p>
<pre class="text"><code>    --vfs-read-wait duration   Time to wait for in-sequence read before seeking (default 20ms)
    --vfs-write-wait duration  Time to wait for in-sequence write before giving error (default 1s)</code></pre>
<p>When using VFS write caching (<code>--vfs-cache-mode</code> with
value writes or full), the global flag <code>--transfers</code> can be
set to adjust the number of parallel uploads of modified files from the
cache (the related global flag <code>--checkers</code> has no effect on
the VFS).</p>
<pre class="text"><code>    --transfers int  Number of file transfers to run in parallel (default 4)</code></pre>
<h2 id="symlinks-8">Symlinks</h2>
<p>By default the VFS does not support symlinks. However this may be
enabled with either of the following flags:</p>
<pre class="text"><code>    --links      Translate symlinks to/from regular files with a &#39;.rclonelink&#39; extension.
    --vfs-links  Translate symlinks to/from regular files with a &#39;.rclonelink&#39; extension for the VFS</code></pre>
<p>As most cloud storage systems do not support symlinks directly,
rclone stores the symlink as a normal file with a special extension. So
a file which appears as a symlink <code>link-to-file.txt</code> would be
stored on cloud storage as <code>link-to-file.txt.rclonelink</code> and
the contents would be the path to the symlink destination.</p>
<p>Note that <code>--links</code> enables symlink translation globally
in rclone - this includes any backend which supports the concept (for
example the local backend). <code>--vfs-links</code> just enables it for
the VFS layer.</p>
<p>This scheme is compatible with that used by the <a
href="https://rclone.org/local/#symlinks-junction-points">local backend
with the --local-links flag</a>.</p>
<p>The <code>--vfs-links</code> flag has been designed for
<code>rclone mount</code>, <code>rclone nfsmount</code> and
<code>rclone serve nfs</code>.</p>
<p>It hasn't been tested with the other <code>rclone serve</code>
commands yet.</p>
<p>A limitation of the current implementation is that it expects the
caller to resolve sub-symlinks. For example given this directory
tree</p>
<pre class="text"><code>.
├── dir
│   └── file.txt
└── linked-dir -&gt; dir</code></pre>
<p>The VFS will correctly resolve <code>linked-dir</code> but not
<code>linked-dir/file.txt</code>. This is not a problem for the tested
commands but may be for other commands.</p>
<p><strong>Note</strong> that there is an outstanding issue with symlink
support <a href="https://github.com/rclone/rclone/issues/8245">issue
#8245</a> with duplicate files being created when symlinks are moved
into directories where there is a file of the same name (or vice
versa).</p>
<h2 id="vfs-case-sensitivity-8">VFS Case Sensitivity</h2>
<p>Linux file systems are case-sensitive: two files can differ only by
case, and the exact case must be used when opening a file.</p>
<p>File systems in modern Windows are case-insensitive but
case-preserving: although existing files can be opened using any case,
the exact case used to create the file is preserved and available for
programs to query. It is not allowed for two files in the same directory
to differ only by case.</p>
<p>Usually file systems on macOS are case-insensitive. It is possible to
make macOS file systems case-sensitive but that is not the default.</p>
<p>The <code>--vfs-case-insensitive</code> VFS flag controls how rclone
handles these two cases. If its value is "false", rclone passes file
names to the remote as-is. If the flag is "true" (or appears without a
value on the command line), rclone may perform a "fixup" as explained
below.</p>
<p>The user may specify a file name to open/delete/rename/etc with a
case different than what is stored on the remote. If an argument refers
to an existing file with exactly the same name, then the case of the
existing file on the disk will be used. However, if a file name with
exactly the same name is not found but a name differing only by case
exists, rclone will transparently fixup the name. This fixup happens
only when an existing file is requested. Case sensitivity of file names
created anew by rclone is controlled by the underlying remote.</p>
<p>Note that case sensitivity of the operating system running rclone
(the target) may differ from case sensitivity of a file system presented
by rclone (the source). The flag controls whether "fixup" is performed
to satisfy the target.</p>
<p>If the flag is not provided on the command line, then its default
value depends on the operating system where rclone runs: "true" on
Windows and macOS, "false" otherwise. If the flag is provided without a
value, then it is "true".</p>
<p>The <code>--no-unicode-normalization</code> flag controls whether a
similar "fixup" is performed for filenames that differ but are <a
href="https://en.wikipedia.org/wiki/Unicode_equivalence">canonically
equivalent</a> with respect to unicode. Unicode normalization can be
particularly helpful for users of macOS, which prefers form NFD instead
of the NFC used by most other platforms. It is therefore highly
recommended to keep the default of <code>false</code> on macOS, to avoid
encoding compatibility issues.</p>
<p>In the (probably unlikely) event that a directory has multiple
duplicate filenames after applying case and unicode normalization, the
<code>--vfs-block-norm-dupes</code> flag allows hiding these duplicates.
This comes with a performance tradeoff, as rclone will have to scan the
entire directory for duplicates when listing a directory. For this
reason, it is recommended to leave this disabled if not needed. However,
macOS users may wish to consider using it, as otherwise, if a remote
directory contains both NFC and NFD versions of the same filename, an
odd situation will occur: both versions of the file will be visible in
the mount, and both will appear to be editable, however, editing either
version will actually result in only the NFD version getting edited
under the hood. <code>--vfs-block- norm-dupes</code> prevents this
confusion by detecting this scenario, hiding the duplicates, and logging
an error, similar to how this is handled in
<code>rclone sync</code>.</p>
<h2 id="vfs-disk-options-8">VFS Disk Options</h2>
<p>This flag allows you to manually set the statistics about the filing
system. It can be useful when those statistics cannot be read correctly
automatically.</p>
<pre class="text"><code>    --vfs-disk-space-total-size    Manually set the total disk space size (example: 256G, default: -1)</code></pre>
<h2 id="alternate-report-of-used-bytes-8">Alternate report of used
bytes</h2>
<p>Some backends, most notably S3, do not report the amount of bytes
used. If you need this information to be available when running
<code>df</code> on the filesystem, then pass the flag
<code>--vfs-used-is-size</code> to rclone. With this flag set, instead
of relying on the backend to report this information, rclone will scan
the whole remote similar to <code>rclone size</code> and compute the
total used space itself.</p>
<p><strong>WARNING</strong>: Contrary to <code>rclone size</code>, this
flag ignores filters so that the result is accurate. However, this is
very inefficient and may cost lots of API calls resulting in extra
charges. Use it as a last resort and only with caching.</p>
<h2 id="vfs-metadata-8">VFS Metadata</h2>
<p>If you use the <code>--vfs-metadata-extension</code> flag you can get
the VFS to expose files which contain the <a
href="https://rclone.org/docs/#metadata">metadata</a> as a JSON blob.
These files will not appear in the directory listing, but can be
<code>stat</code>-ed and opened and once they have been they
<strong>will</strong> appear in directory listings until the directory
cache expires.</p>
<p>Note that some backends won't create metadata unless you pass in the
<code>--metadata</code> flag.</p>
<p>For example, using <code>rclone mount</code> with
<code>--metadata --vfs-metadata-extension .metadata</code> we get</p>
<pre class="console"><code>$ ls -l /mnt/
total 1048577
-rw-rw-r-- 1 user user 1073741824 Mar  3 16:03 1G

$ cat /mnt/1G.metadata
{
        &quot;atime&quot;: &quot;2025-03-04T17:34:22.317069787Z&quot;,

-rw-rw-r-- 1 user user        185 Mar  3 16:03 1G.metadata</code></pre>
<p>If the file has no metadata it will be returned as <code>{}</code>
and if there is an error reading the metadata the error will be returned
as <code>{"error":"error string"}</code>.</p>
<h2 id="auth-proxy-2">Auth Proxy</h2>
<p>If you supply the parameter
<code>--auth-proxy /path/to/program</code> then rclone will use that
program to generate backends on the fly which then are used to
authenticate incoming requests. This uses a simple JSON based protocol
with input on STDIN and output on STDOUT.</p>
<p><strong>PLEASE NOTE:</strong> <code>--auth-proxy</code> and
<code>--authorized-keys</code> cannot be used together, if
<code>--auth-proxy</code> is set the authorized keys option will be
ignored.</p>
<p>There is an example program <a
href="https://github.com/rclone/rclone/blob/master/bin/test_proxy.py">bin/test_proxy.py</a>
in the rclone source code.</p>
<p>The program's job is to take a <code>user</code> and
<code>pass</code> on the input and turn those into the config for a
backend on STDOUT in JSON format. This config will have any default
parameters for the backend added, but it won't use configuration from
environment variables or command line options - it is the job of the
proxy program to make a complete config.</p>
<p>This config generated must have this extra parameter</p>
<ul>
<li><code>_root</code> - root to use for the backend</li>
</ul>
<p>And it may have this parameter</p>
<ul>
<li><code>_obscure</code> - comma separated strings for parameters to
obscure</li>
</ul>
<p>If password authentication was used by the client, input to the proxy
process (on STDIN) would look similar to this:</p>
<div class="sourceCode" id="cb575"><pre

<p>This would mean that an SFTP backend would be created on the fly for
the <code>user</code> and <code>pass</code>/<code>public_key</code>
returned in the output to the host given. Note that since
<code>_obscure</code> is set to <code>pass</code>, rclone will obscure
the <code>pass</code> parameter before creating the backend (which is
required for sftp backends).</p>
<p>The program can manipulate the supplied <code>user</code> in any way,
for example to make proxy to many different sftp backends, you could
make the <code>user</code> be <code>user@example.com</code> and then set
the <code>host</code> to <code>example.com</code> in the output and the
user to <code>user</code>. For security you'd probably want to restrict
the <code>host</code> to a limited list.</p>
<p>Note that an internal cache is keyed on <code>user</code> so only use
that for configuration, don't use <code>pass</code> or
<code>public_key</code>. This also means that if a user's password or
public-key is changed the cache will need to expire (which takes 5 mins)
before it takes effect.</p>
<p>This can be used to build general purpose proxies to any kind of
backend that rclone supports.</p>

<p>Serve remote:path over WebDAV.</p>
<h2 id="synopsis-78">Synopsis</h2>
<p>Run a basic WebDAV server to serve a remote over HTTP via the WebDAV
protocol. This can be viewed with a WebDAV client, through a web
browser, or you can make a remote of type WebDAV to read and write
it.</p>
<h2 id="webdav-options">WebDAV options</h2>
<h3 id="etag-hash">--etag-hash</h3>
<p>This controls the ETag header. Without this flag the ETag will be
based on the ModTime and Size of the object.</p>
<p>If this flag is set to "auto" then rclone will choose the first
supported hash on the backend or you can use a named hash such as "MD5"
or "SHA-1". Use the <a

to see the full list.</p>
<h2 id="access-webdav-on-windows">Access WebDAV on Windows</h2>
<p>WebDAV shared folder can be mapped as a drive on Windows, however the
default settings prevent it. Windows will fail to connect to the server
using insecure Basic authentication. It will not even display any login
dialog. Windows requires SSL / HTTPS connection to be used with Basic.
If you try to connect via Add Network Location Wizard you will get the
following error: "The folder you entered does not appear to be valid.
Please choose another". However, you still can connect if you set the
following registry key on a client machine:
<code>HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters\BasicAuthLevel</code>
to 2. The BasicAuthLevel can be set to the following values:</p>
<pre class="text"><code>0 - Basic authentication disabled
1 - Basic authentication enabled for SSL connections only
2 - Basic authentication enabled for SSL connections and for non-SSL connections</code></pre>
<p>If required, increase the FileSizeLimitInBytes to a higher value.
Navigate to the Services interface, then restart the WebClient
service.</p>

<h2 id="serving-over-a-unix-socket">Serving over a unix socket</h2>
<p>You can serve the webdav on a unix socket like this:</p>
<pre class="console"><code>rclone serve webdav --addr unix:///tmp/my.socket remote:path</code></pre>
<p>and connect to it like this using rclone and the webdav backend:</p>
<pre class="console"><code>rclone --webdav-unix-socket /tmp/my.socket --webdav-url http://localhost lsf :webdav:</code></pre>
<p>Note that there is no authentication on http protocol - this is
expected to be done by the permissions on the socket.</p>
<h2 id="server-options-6">Server options</h2>
<p>Use <code>--addr</code> to specify which IP address and port the
server should listen on, eg <code>--addr 1.2.3.4:8000</code> or
<code>--addr :8080</code> to listen to all IPs. By default it only
listens on localhost. You can use port :0 to let the OS choose an
available port.</p>
<p>If you set <code>--addr</code> to listen on a public or LAN
accessible IP address then using Authentication is advised - see the
next section for info.</p>
<p>You can use a unix socket by setting the url to
<code>unix:///path/to/socket</code> or just by using an absolute path
name.</p>
<p><code>--addr</code> may be repeated to listen on multiple
IPs/ports/sockets. Socket activation, described further below, can also
be used to accomplish the same.</p>
<p><code>--server-read-timeout</code> and
<code>--server-write-timeout</code> can be used to control the timeouts
on the server. Note that this is the total time for a transfer.</p>
<p><code>--max-header-bytes</code> controls the maximum number of bytes
the server will accept in the HTTP header.</p>
<p><code>--baseurl</code> controls the URL prefix that rclone serves
from. By default rclone will serve from the root. If you used
<code>--baseurl "/rclone"</code> then rclone would serve from a URL
starting with "/rclone/". This is useful if you wish to proxy rclone
serve. Rclone automatically inserts leading and trailing "/" on
<code>--baseurl</code>, so <code>--baseurl "rclone"</code>,
<code>--baseurl "/rclone"</code> and <code>--baseurl "/rclone/"</code>
are all treated identically.</p>
<p><code>--disable-zip</code> may be set to disable the zipping download
option.</p>
<h3 id="tls-ssl-4">TLS (SSL)</h3>
<p>By default this will serve over http. If you want you can serve over
https. You will need to supply the <code>--cert</code> and
<code>--key</code> flags. If you wish to do client side certificate
validation then you will need to supply <code>--client-ca</code>
also.</p>
<p><code>--cert</code> must be set to the path of a file containing
either a PEM encoded certificate, or a concatenation of that with the CA
certificate. <code>--key</code> must be set to the path of a file with
the PEM encoded private key. If setting <code>--client-ca</code>, it
should be set to the path of a file with PEM encoded client certificate
authority certificates.</p>
<p><code>--min-tls-version</code> is minimum TLS version that is
acceptable. Valid values are "tls1.0", "tls1.1", "tls1.2" and "tls1.3"
(default "tls1.0").</p>
<h2 id="socket-activation-4">Socket activation</h2>
<p>Instead of the listening addresses specified above, rclone will
listen to all FDs passed by the service manager, if any (and ignore any
arguments passed by <code>--addr</code>).</p>
<p>This allows rclone to be a socket-activated service. It can be
configured with .socket and .service unit files as described in <a
href="https://www.freedesktop.org/software/systemd/man/latest/systemd.socket.html"
class="uri">https://www.freedesktop.org/software/systemd/man/latest/systemd.socket.html</a>.</p>
<p>Socket activation can be tested ad-hoc with the
<code>systemd-socket-activate</code>command</p>
<pre class="console"><code>systemd-socket-activate -l 8000 -- rclone serve</code></pre>
<p>This will socket-activate rclone on the first connection to port 8000
over TCP.</p>
<h3 id="template-2">Template</h3>
<p><code>--template</code> allows a user to specify a custom markup
template for HTTP and WebDAV serve functions. The server exports the

<h3 id="authentication-5">Authentication</h3>
<p>By default this will serve files without needing a login.</p>
<p>You can either use an htpasswd file which can take lots of users, or
set a single username and password with the <code>--user</code> and
<code>--pass</code> flags.</p>
<p>Alternatively, you can have the reverse proxy manage authentication
and use the username provided in the configured header with
<code>--user-from-header</code> (e.g.,
<code>--user-from-header=x-remote-user</code>). Ensure the proxy is
trusted and headers cannot be spoofed, as misconfiguration may lead to
unauthorized access.</p>
<p>If either of the above authentication methods is not configured and
client certificates are required by the <code>--client-ca</code> flag
passed to the server, the client certificate common name will be
considered as the username.</p>
<p>Use <code>--htpasswd /path/to/htpasswd</code> to provide an htpasswd
file. This is in standard apache format and supports MD5, SHA1 and
BCrypt for basic authentication. Bcrypt is recommended.</p>
<p>To create an htpasswd file:</p>
<pre class="console"><code>touch htpasswd
htpasswd -B htpasswd user
htpasswd -B htpasswd anotherUser</code></pre>
<p>The password file can be updated while rclone is running.</p>
<p>Use <code>--realm</code> to set the authentication realm.</p>
<p>Use <code>--salt</code> to change the password hashing salt from the
default.</p>
<h2 id="vfs---virtual-file-system-9">VFS - Virtual File System</h2>
<p>This command uses the VFS layer. This adapts the cloud storage
objects that rclone uses into something which looks much more like a
disk filing system.</p>
<p>Cloud storage objects have lots of properties which aren't like disk
files - you can't extend them or write to the middle of them, so the VFS
layer has to deal with that. Because there is no one right way of doing
this there are various options explained below.</p>
<p>The VFS layer also implements a directory cache - this caches info
about files and directories (but not the data) in memory.</p>
<h2 id="vfs-directory-cache-9">VFS Directory Cache</h2>
<p>Using the <code>--dir-cache-time</code> flag, you can control how
long a directory should be considered up to date and not refreshed from
the backend. Changes made through the VFS will appear immediately or
invalidate the cache.</p>
<pre class="text"><code>    --dir-cache-time duration   Time to cache directory entries for (default 5m0s)
    --poll-interval duration    Time to wait between polling for changes. Must be smaller than dir-cache-time. Only on supported remotes. Set to 0 to disable (default 1m0s)</code></pre>
<p>However, changes made directly on the cloud storage by the web
interface or a different copy of rclone will only be picked up once the
directory cache expires if the backend configured does not support
polling for changes. If the backend supports polling, changes will be
picked up within the polling interval.</p>
<p>You can send a <code>SIGHUP</code> signal to rclone for it to flush
all directory caches, regardless of how old they are. Assuming only one
rclone instance is running, you can reset the cache like this:</p>
<pre class="console"><code>kill -SIGHUP $(pidof rclone)</code></pre>
<p>If you configure rclone with a <a href="/rc">remote control</a> then
you can use rclone rc to flush the whole directory cache:</p>
<pre class="console"><code>rclone rc vfs/forget</code></pre>
<p>Or individual files or directories:</p>
<pre class="console"><code>rclone rc vfs/forget file=path/to/file dir=path/to/dir</code></pre>
<h2 id="vfs-file-buffering-9">VFS File Buffering</h2>
<p>The <code>--buffer-size</code> flag determines the amount of memory,
that will be used to buffer data in advance.</p>
<p>Each open file will try to keep the specified amount of data in
memory at all times. The buffered data is bound to one open file and
won't be shared.</p>
<p>This flag is a upper limit for the used memory per open file. The
buffer will only use memory for data that is downloaded but not not yet
read. If the buffer is empty, only a small amount of memory will be
used.</p>
<p>The maximum memory used by rclone for buffering can be up to
<code>--buffer-size * open files</code>.</p>
<h2 id="vfs-file-caching-9">VFS File Caching</h2>
<p>These flags control the VFS file caching options. File caching is
necessary to make the VFS layer appear compatible with a normal file
system. It can be disabled at the cost of some compatibility.</p>
<p>For example you'll need to enable VFS caching if you want to read and
write simultaneously to a file. See below for more details.</p>
<p>Note that the VFS cache is separate from the cache backend and you
may find that you need one or the other or both.</p>
<pre class="text"><code>    --cache-dir string                     Directory rclone will use for caching.
    --vfs-cache-mode CacheMode             Cache mode off|minimal|writes|full (default off)
    --vfs-cache-max-age duration           Max time since last access of objects in the cache (default 1h0m0s)
    --vfs-cache-max-size SizeSuffix        Max total size of objects in the cache (default off)
    --vfs-cache-min-free-space SizeSuffix  Target minimum free space on the disk containing the cache (default off)
    --vfs-cache-poll-interval duration     Interval to poll the cache for stale objects (default 1m0s)
    --vfs-write-back duration              Time to writeback files after last use when using cache (default 5s)</code></pre>
<p>If run with <code>-vv</code> rclone will print the location of the
file cache. The files are stored in the user cache file area which is OS
dependent but can be controlled with <code>--cache-dir</code> or setting
the appropriate environment variable.</p>
<p>The cache has 4 different modes selected by
<code>--vfs-cache-mode</code>. The higher the cache mode the more
compatible rclone becomes at the cost of using disk space.</p>
<p>Note that files are written back to the remote only when they are
closed and if they haven't been accessed for
<code>--vfs-write-back</code> seconds. If rclone is quit or dies with
files that haven't been uploaded, these will be uploaded next time
rclone is run with the same flags.</p>
<p>If using <code>--vfs-cache-max-size</code> or
<code>--vfs-cache-min-free-space</code> note that the cache may exceed
these quotas for two reasons. Firstly because it is only checked every
<code>--vfs-cache-poll-interval</code>. Secondly because open files
cannot be evicted from the cache. When <code>--vfs-cache-max-size</code>
or <code>--vfs-cache-min-free-space</code> is exceeded, rclone will
attempt to evict the least accessed files from the cache first. rclone
will start with files that haven't been accessed for the longest. This
cache flushing strategy is efficient and more relevant files are likely
to remain cached.</p>
<p>The <code>--vfs-cache-max-age</code> will evict files from the cache
after the set time since last access has passed. The default value of 1
hour will start evicting files from cache that haven't been accessed for
1 hour. When a cached file is accessed the 1 hour timer is reset to 0
and will wait for 1 more hour before evicting. Specify the time with
standard notation, s, m, h, d, w .</p>
<p>You <strong>should not</strong> run two copies of rclone using the
same VFS cache with the same or overlapping remotes if using
<code>--vfs-cache-mode &gt; off</code>. This can potentially cause data
corruption if you do. You can work around this by giving each rclone its
own cache hierarchy with <code>--cache-dir</code>. You don't need to
worry about this if the remotes in use don't overlap.</p>
<h3 id="vfs-cache-mode-off-9">--vfs-cache-mode off</h3>
<p>In this mode (the default) the cache will read directly from the
remote and write directly to the remote without caching anything on
disk.</p>
<p>This will mean some operations are not possible</p>
<ul>
<li>Files can't be opened for both read AND write</li>
<li>Files opened for write can't be seeked</li>
<li>Existing files opened for write must have O_TRUNC set</li>
<li>Files open for read with O_TRUNC will be opened write only</li>
<li>Files open for write only will behave as if O_TRUNC was
supplied</li>
<li>Open modes O_APPEND, O_TRUNC are ignored</li>
<li>If an upload fails it can't be retried</li>
</ul>
<h3 id="vfs-cache-mode-minimal-9">--vfs-cache-mode minimal</h3>
<p>This is very similar to "off" except that files opened for read AND
write will be buffered to disk. This means that files opened for write
will be a lot more compatible, but uses the minimal disk space.</p>
<p>These operations are not possible</p>
<ul>
<li>Files opened for write only can't be seeked</li>
<li>Existing files opened for write must have O_TRUNC set</li>
<li>Files opened for write only will ignore O_APPEND, O_TRUNC</li>
<li>If an upload fails it can't be retried</li>
</ul>
<h3 id="vfs-cache-mode-writes-9">--vfs-cache-mode writes</h3>
<p>In this mode files opened for read only are still read directly from
the remote, write only and read/write files are buffered to disk
first.</p>
<p>This mode should support all normal file system operations.</p>
<p>If an upload fails it will be retried at exponentially increasing
intervals up to 1 minute.</p>
<h3 id="vfs-cache-mode-full-9">--vfs-cache-mode full</h3>
<p>In this mode all reads and writes are buffered to and from disk. When
data is read from the remote this is buffered to disk as well.</p>
<p>In this mode the files in the cache will be sparse files and rclone
will keep track of which bits of the files it has downloaded.</p>
<p>So if an application only reads the starts of each file, then rclone
will only buffer the start of the file. These files will appear to be
their full size in the cache, but they will be sparse files with only
the data that has been downloaded present in them.</p>
<p>This mode should support all normal file system operations and is
otherwise identical to <code>--vfs-cache-mode</code> writes.</p>
<p>When reading a file rclone will read <code>--buffer-size</code> plus
<code>--vfs-read-ahead</code> bytes ahead. The
<code>--buffer-size</code> is buffered in memory whereas the
<code>--vfs-read-ahead</code> is buffered on disk.</p>
<p>When using this mode it is recommended that
<code>--buffer-size</code> is not set too large and
<code>--vfs-read-ahead</code> is set large if required.</p>
<p><strong>IMPORTANT</strong> not all file systems support sparse files.
In particular FAT/exFAT do not. Rclone will perform very badly if the
cache directory is on a filesystem which doesn't support sparse files
and it will log an ERROR message if one is detected.</p>
<h3 id="fingerprinting-9">Fingerprinting</h3>
<p>Various parts of the VFS use fingerprinting to see if a local file
copy has changed relative to a remote file. Fingerprints are made
from:</p>
<ul>
<li>size</li>
<li>modification time</li>
<li>hash</li>
</ul>
<p>where available on an object.</p>
<p>On some backends some of these attributes are slow to read (they take
an extra API call per object, or extra work per object).</p>
<p>For example <code>hash</code> is slow with the <code>local</code> and
<code>sftp</code> backends as they have to read the entire file and hash
it, and <code>modtime</code> is slow with the <code>s3</code>,
<code>swift</code>, <code>ftp</code> and <code>qinqstor</code> backends
because they need to do an extra API call to fetch it.</p>
<p>If you use the <code>--vfs-fast-fingerprint</code> flag then rclone
will not include the slow operations in the fingerprint. This makes the
fingerprinting less accurate but much faster and will improve the
opening time of cached files.</p>
<p>If you are running a vfs cache over <code>local</code>,
<code>s3</code> or <code>swift</code> backends then using this flag is
recommended.</p>
<p>Note that if you change the value of this flag, the fingerprints of
the files in the cache may be invalidated and the files will need to be
downloaded again.</p>
<h2 id="vfs-chunked-reading-9">VFS Chunked Reading</h2>
<p>When rclone reads files from a remote it reads them in chunks. This
means that rather than requesting the whole file rclone reads the chunk
specified. This can reduce the used download quota for some remotes by
requesting only chunks from the remote that are actually read, at the
cost of an increased number of requests.</p>
<p>These flags control the chunking:</p>
<pre class="text"><code>    --vfs-read-chunk-size SizeSuffix        Read the source objects in chunks (default 128M)
    --vfs-read-chunk-size-limit SizeSuffix  Max chunk doubling size (default off)
    --vfs-read-chunk-streams int            The number of parallel streams to read at once</code></pre>
<p>The chunking behaves differently depending on the
<code>--vfs-read-chunk-streams</code> parameter.</p>
<h3
id="vfs-read-chunk-streams-0-18"><code>--vfs-read-chunk-streams</code>
== 0</h3>
<p>Rclone will start reading a chunk of size
<code>--vfs-read-chunk-size</code>, and then double the size for each
read. When <code>--vfs-read-chunk-size-limit</code> is specified, and
greater than <code>--vfs-read-chunk-size</code>, the chunk size for each
open file will get doubled only until the specified value is reached. If
the value is "off", which is the default, the limit is disabled and the
chunk size will grow indefinitely.</p>
<p>With <code>--vfs-read-chunk-size 100M</code> and
<code>--vfs-read-chunk-size-limit 0</code> the following parts will be
downloaded: 0-100M, 100M-200M, 200M-300M, 300M-400M and so on. When
<code>--vfs-read-chunk-size-limit 500M</code> is specified, the result
would be 0-100M, 100M-300M, 300M-700M, 700M-1200M, 1200M-1700M and so
on.</p>
<p>Setting <code>--vfs-read-chunk-size</code> to <code>0</code> or "off"
disables chunked reading.</p>
<p>The chunks will not be buffered in memory.</p>
<h3
id="vfs-read-chunk-streams-0-19"><code>--vfs-read-chunk-streams</code>
&gt; 0</h3>
<p>Rclone reads <code>--vfs-read-chunk-streams</code> chunks of size
<code>--vfs-read-chunk-size</code> concurrently. The size for each read
will stay constant.</p>
<p>This improves performance performance massively on high latency links
or very high bandwidth links to high performance object stores.</p>
<p>Some experimentation will be needed to find the optimum values of
<code>--vfs-read-chunk-size</code> and
<code>--vfs-read-chunk-streams</code> as these will depend on the
backend in use and the latency to the backend.</p>
<p>For high performance object stores (eg AWS S3) a reasonable place to
start might be <code>--vfs-read-chunk-streams 16</code> and
<code>--vfs-read-chunk-size 4M</code>. In testing with AWS S3 the
performance scaled roughly as the <code>--vfs-read-chunk-streams</code>
setting.</p>
<p>Similar settings should work for high latency links, but depending on
the latency they may need more <code>--vfs-read-chunk-streams</code> in
order to get the throughput.</p>
<h2 id="vfs-performance-9">VFS Performance</h2>
<p>These flags may be used to enable/disable features of the VFS for
performance or other reasons. See also the <a
href="#vfs-chunked-reading">chunked reading</a> feature.</p>
<p>In particular S3 and Swift benefit hugely from the
<code>--no-modtime</code> flag (or use <code>--use-server-modtime</code>
for a slightly different effect) as each read of the modification time
takes a transaction.</p>
<pre class="text"><code>    --no-checksum     Don&#39;t compare checksums on up/download.
    --no-modtime      Don&#39;t read/write the modification time (can speed things up).
    --no-seek         Don&#39;t allow seeking in files.
    --read-only       Only allow read-only access.</code></pre>
<p>Sometimes rclone is delivered reads or writes out of order. Rather
than seeking rclone will wait a short time for the in sequence read or
write to come in. These flags only come into effect when not using an on
disk cache file.</p>
<pre class="text"><code>    --vfs-read-wait duration   Time to wait for in-sequence read before seeking (default 20ms)
    --vfs-write-wait duration  Time to wait for in-sequence write before giving error (default 1s)</code></pre>
<p>When using VFS write caching (<code>--vfs-cache-mode</code> with
value writes or full), the global flag <code>--transfers</code> can be
set to adjust the number of parallel uploads of modified files from the
cache (the related global flag <code>--checkers</code> has no effect on
the VFS).</p>
<pre class="text"><code>    --transfers int  Number of file transfers to run in parallel (default 4)</code></pre>
<h2 id="symlinks-9">Symlinks</h2>
<p>By default the VFS does not support symlinks. However this may be
enabled with either of the following flags:</p>
<pre class="text"><code>    --links      Translate symlinks to/from regular files with a &#39;.rclonelink&#39; extension.
    --vfs-links  Translate symlinks to/from regular files with a &#39;.rclonelink&#39; extension for the VFS</code></pre>
<p>As most cloud storage systems do not support symlinks directly,
rclone stores the symlink as a normal file with a special extension. So
a file which appears as a symlink <code>link-to-file.txt</code> would be
stored on cloud storage as <code>link-to-file.txt.rclonelink</code> and
the contents would be the path to the symlink destination.</p>
<p>Note that <code>--links</code> enables symlink translation globally
in rclone - this includes any backend which supports the concept (for
example the local backend). <code>--vfs-links</code> just enables it for
the VFS layer.</p>
<p>This scheme is compatible with that used by the <a
href="https://rclone.org/local/#symlinks-junction-points">local backend
with the --local-links flag</a>.</p>
<p>The <code>--vfs-links</code> flag has been designed for
<code>rclone mount</code>, <code>rclone nfsmount</code> and
<code>rclone serve nfs</code>.</p>
<p>It hasn't been tested with the other <code>rclone serve</code>
commands yet.</p>
<p>A limitation of the current implementation is that it expects the
caller to resolve sub-symlinks. For example given this directory
tree</p>
<pre class="text"><code>.
├── dir
│   └── file.txt
└── linked-dir -&gt; dir</code></pre>
<p>The VFS will correctly resolve <code>linked-dir</code> but not
<code>linked-dir/file.txt</code>. This is not a problem for the tested
commands but may be for other commands.</p>
<p><strong>Note</strong> that there is an outstanding issue with symlink
support <a href="https://github.com/rclone/rclone/issues/8245">issue
#8245</a> with duplicate files being created when symlinks are moved
into directories where there is a file of the same name (or vice
versa).</p>
<h2 id="vfs-case-sensitivity-9">VFS Case Sensitivity</h2>
<p>Linux file systems are case-sensitive: two files can differ only by
case, and the exact case must be used when opening a file.</p>
<p>File systems in modern Windows are case-insensitive but
case-preserving: although existing files can be opened using any case,
the exact case used to create the file is preserved and available for
programs to query. It is not allowed for two files in the same directory
to differ only by case.</p>
<p>Usually file systems on macOS are case-insensitive. It is possible to
make macOS file systems case-sensitive but that is not the default.</p>
<p>The <code>--vfs-case-insensitive</code> VFS flag controls how rclone
handles these two cases. If its value is "false", rclone passes file
names to the remote as-is. If the flag is "true" (or appears without a
value on the command line), rclone may perform a "fixup" as explained
below.</p>
<p>The user may specify a file name to open/delete/rename/etc with a
case different than what is stored on the remote. If an argument refers
to an existing file with exactly the same name, then the case of the
existing file on the disk will be used. However, if a file name with
exactly the same name is not found but a name differing only by case
exists, rclone will transparently fixup the name. This fixup happens
only when an existing file is requested. Case sensitivity of file names
created anew by rclone is controlled by the underlying remote.</p>
<p>Note that case sensitivity of the operating system running rclone
(the target) may differ from case sensitivity of a file system presented
by rclone (the source). The flag controls whether "fixup" is performed
to satisfy the target.</p>
<p>If the flag is not provided on the command line, then its default
value depends on the operating system where rclone runs: "true" on
Windows and macOS, "false" otherwise. If the flag is provided without a
value, then it is "true".</p>
<p>The <code>--no-unicode-normalization</code> flag controls whether a
similar "fixup" is performed for filenames that differ but are <a
href="https://en.wikipedia.org/wiki/Unicode_equivalence">canonically
equivalent</a> with respect to unicode. Unicode normalization can be
particularly helpful for users of macOS, which prefers form NFD instead
of the NFC used by most other platforms. It is therefore highly
recommended to keep the default of <code>false</code> on macOS, to avoid
encoding compatibility issues.</p>
<p>In the (probably unlikely) event that a directory has multiple
duplicate filenames after applying case and unicode normalization, the
<code>--vfs-block-norm-dupes</code> flag allows hiding these duplicates.
This comes with a performance tradeoff, as rclone will have to scan the
entire directory for duplicates when listing a directory. For this
reason, it is recommended to leave this disabled if not needed. However,
macOS users may wish to consider using it, as otherwise, if a remote
directory contains both NFC and NFD versions of the same filename, an
odd situation will occur: both versions of the file will be visible in
the mount, and both will appear to be editable, however, editing either
version will actually result in only the NFD version getting edited
under the hood. <code>--vfs-block- norm-dupes</code> prevents this
confusion by detecting this scenario, hiding the duplicates, and logging
an error, similar to how this is handled in
<code>rclone sync</code>.</p>
<h2 id="vfs-disk-options-9">VFS Disk Options</h2>
<p>This flag allows you to manually set the statistics about the filing
system. It can be useful when those statistics cannot be read correctly
automatically.</p>
<pre class="text"><code>    --vfs-disk-space-total-size    Manually set the total disk space size (example: 256G, default: -1)</code></pre>
<h2 id="alternate-report-of-used-bytes-9">Alternate report of used
bytes</h2>
<p>Some backends, most notably S3, do not report the amount of bytes
used. If you need this information to be available when running
<code>df</code> on the filesystem, then pass the flag
<code>--vfs-used-is-size</code> to rclone. With this flag set, instead
of relying on the backend to report this information, rclone will scan
the whole remote similar to <code>rclone size</code> and compute the
total used space itself.</p>
<p><strong>WARNING</strong>: Contrary to <code>rclone size</code>, this
flag ignores filters so that the result is accurate. However, this is
very inefficient and may cost lots of API calls resulting in extra
charges. Use it as a last resort and only with caching.</p>
<h2 id="vfs-metadata-9">VFS Metadata</h2>
<p>If you use the <code>--vfs-metadata-extension</code> flag you can get
the VFS to expose files which contain the <a
href="https://rclone.org/docs/#metadata">metadata</a> as a JSON blob.
These files will not appear in the directory listing, but can be
<code>stat</code>-ed and opened and once they have been they
<strong>will</strong> appear in directory listings until the directory
cache expires.</p>
<p>Note that some backends won't create metadata unless you pass in the
<code>--metadata</code> flag.</p>
<p>For example, using <code>rclone mount</code> with
<code>--metadata --vfs-metadata-extension .metadata</code> we get</p>
<pre class="console"><code>$ ls -l /mnt/
total 1048577
-rw-rw-r-- 1 user user 1073741824 Mar  3 16:03 1G

$ cat /mnt/1G.metadata
{
        &quot;atime&quot;: &quot;2025-03-04T17:34:22.317069787Z&quot;,

-rw-rw-r-- 1 user user        185 Mar  3 16:03 1G.metadata</code></pre>
<p>If the file has no metadata it will be returned as <code>{}</code>
and if there is an error reading the metadata the error will be returned
as <code>{"error":"error string"}</code>.</p>
<h2 id="auth-proxy-3">Auth Proxy</h2>
<p>If you supply the parameter
<code>--auth-proxy /path/to/program</code> then rclone will use that
program to generate backends on the fly which then are used to
authenticate incoming requests. This uses a simple JSON based protocol
with input on STDIN and output on STDOUT.</p>
<p><strong>PLEASE NOTE:</strong> <code>--auth-proxy</code> and
<code>--authorized-keys</code> cannot be used together, if
<code>--auth-proxy</code> is set the authorized keys option will be
ignored.</p>
<p>There is an example program <a
href="https://github.com/rclone/rclone/blob/master/bin/test_proxy.py">bin/test_proxy.py</a>
in the rclone source code.</p>
<p>The program's job is to take a <code>user</code> and
<code>pass</code> on the input and turn those into the config for a
backend on STDOUT in JSON format. This config will have any default
parameters for the backend added, but it won't use configuration from
environment variables or command line options - it is the job of the
proxy program to make a complete config.</p>
<p>This config generated must have this extra parameter</p>
<ul>
<li><code>_root</code> - root to use for the backend</li>
</ul>
<p>And it may have this parameter</p>
<ul>
<li><code>_obscure</code> - comma separated strings for parameters to
obscure</li>
</ul>
<p>If password authentication was used by the client, input to the proxy
process (on STDIN) would look similar to this:</p>
<div class="sourceCode" id="cb600"><pre

<p>If public-key authentication was used by the client, input to the
proxy process (on STDIN) would look similar to this:</p>

<p>This would mean that an SFTP backend would be created on the fly for
the <code>user</code> and <code>pass</code>/<code>public_key</code>
returned in the output to the host given. Note that since
<code>_obscure</code> is set to <code>pass</code>, rclone will obscure
the <code>pass</code> parameter before creating the backend (which is
required for sftp backends).</p>
<p>The program can manipulate the supplied <code>user</code> in any way,
for example to make proxy to many different sftp backends, you could
make the <code>user</code> be <code>user@example.com</code> and then set
the <code>host</code> to <code>example.com</code> in the output and the
user to <code>user</code>. For security you'd probably want to restrict
the <code>host</code> to a limited list.</p>
<p>Note that an internal cache is keyed on <code>user</code> so only use
that for configuration, don't use <code>pass</code> or
<code>public_key</code>. This also means that if a user's password or
public-key is changed the cache will need to expire (which takes 5 mins)
before it takes effect.</p>
<p>This can be used to build general purpose proxies to any kind of
backend that rclone supports.</p>

<p>Changes storage class/tier of objects in remote.</p>
<h2 id="synopsis-79">Synopsis</h2>
<p>Changes storage tier or class at remote if supported. Few cloud
storage services provides different storage classes on objects, for
example AWS S3 and Glacier, Azure Blob storage - Hot, Cool and Archive,
Google Cloud Storage, Regional Storage, Nearline, Coldline etc.</p>
<p>Note that, certain tier changes make objects not available to access
immediately. For example tiering to archive in azure blob storage makes
objects in frozen state, user can restore by setting tier to Hot/Cool,
similarly S3 to Glacier makes object inaccessible.true</p>
<p>You can use it to tier single object</p>
<pre class="console"><code>rclone settier Cool remote:path/file</code></pre>
<p>Or use rclone filters to set tier on only specific files</p>
<pre class="console"><code>rclone --include &quot;*.txt&quot; settier Hot remote:path/dir</code></pre>
<p>Or just provide remote directory and all files in directory will be

<p>Run a speed test to the remote</p>
<h2 id="synopsis-83">Synopsis</h2>
<p>Run a speed test to the remote.</p>
<p>This command runs a series of uploads and downloads to the remote,
measuring and printing the speed of each test using varying file sizes
and numbers of files.</p>
<p>Test time can be innaccurate with small file caps and large files. As
it uses the results of an initial test to determine how many files to
use in each subsequent test.</p>
<p>It is recommended to use -q flag for a simpler output. e.g.:</p>
<pre><code>rclone test speed remote: -q</code></pre>
<p><strong>NB</strong> This command will create and delete files on the
remote in a randomly named directory which will be automatically removed
on a clean exit.</p>
<p>You can use the --json flag to only print the results in JSON
format.</p>

<p>Create new file or change file modification time.</p>
<h2 id="synopsis-84">Synopsis</h2>
<p>Set the modification time on file(s) as specified by remote:path to

<p>If remote:path does not exist then a zero sized file will be created,
unless <code>--no-create</code> or <code>--recursive</code> is
provided.</p>
<p>If <code>--recursive</code> is used then recursively sets the
modification time on all existing files that is found under the path.
Filters are supported, and you can test with the <code>--dry-run</code>
or the <code>--interactive</code>/<code>-i</code> flag. This will touch
<code>--transfers</code> files concurrently.</p>
<p>If <code>--timestamp</code> is used then sets the modification time
to that time instead of the current time. Times may be specified as one
of:</p>
<ul>
<li>'YYMMDD' - e.g. 17.10.30</li>
<li>'YYYY-MM-DDTHH:MM:SS' - e.g. 2006-01-02T15:04:05</li>
<li>'YYYY-MM-DDTHH:MM:SS.SSS' - e.g. 2006-01-02T15:04:05.123456789</li>

<h1 id="rclone-tree">rclone tree</h1>
<p>List the contents of the remote in a tree like fashion.</p>
<h2 id="synopsis-85">Synopsis</h2>
<p>Lists the contents of a remote in a similar way to the unix tree
command.</p>
<p>For example</p>
<pre class="text"><code>$ rclone tree remote:path
/
├── file1
├── file2
├── file3
└── subdir
    ├── file4
    └── file5

1 directories, 5 files</code></pre>
<p>You can use any of the filtering options with the tree command (e.g.
<code>--include</code> and <code>--exclude</code>. You can also use
<code>--fast-list</code>.</p>
<p>The tree command has many options for controlling the listing which
are compatible with the tree command, for example you can include file
sizes with <code>--size</code>. Note that not all of them have short
options as they conflict with rclone's short options.</p>
<p>For a more interactive navigation of the remote see the <a
href="https://rclone.org/commands/rclone_ncdu/">ncdu</a> command.</p>
<pre><code>rclone tree remote:path [flags]</code></pre>
<h2 id="options-96">Options</h2>
<pre><code>  -a, --all             All files are listed (list . files too)
  -d, --dirs-only       List directories only

  -o, --output string   Output to file instead of stdout
  -p, --protections     Print the protections for each file.
  -Q, --quote           Quote filenames with double quotes.
  -s, --size            Print the size in bytes of each file.

<h2 id="copying-single-files">Copying single files</h2>
<p>rclone normally syncs or copies directories. However, if the source
remote points to a file, rclone will just copy that file. The
destination remote must point to a directory - rclone will give the
error
<code>Failed to create file system for "remote:file": is a file not a directory</code>
if it isn't.</p>
<p>For example, suppose you have a remote with a file in called
<code>test.jpg</code>, then you could copy just that file like this</p>
<pre class="console"><code>rclone copy remote:test.jpg /tmp/download</code></pre>
<p>The file <code>test.jpg</code> will be placed inside
<code>/tmp/download</code>.</p>
<p>This is equivalent to specifying</p>
<pre class="console"><code>rclone copy --files-from /tmp/files remote: /tmp/download</code></pre>
<p>Where <code>/tmp/files</code> contains the single line</p>
<pre class="console"><code>test.jpg</code></pre>
<p>It is recommended to use <code>copy</code> when copying individual
files, not <code>sync</code>. They have pretty much the same effect but
<code>copy</code> will use a lot less memory.</p>
<h2 id="syntax-of-remote-paths">Syntax of remote paths</h2>
<p>The syntax of the paths passed to the rclone command are as
follows.</p>
<h3 id="pathtodir">/path/to/dir</h3>
<p>This refers to the local file system.</p>
<p>On Windows <code>\</code> may be used instead of <code>/</code> in
local paths <strong>only</strong>, non local paths must use
<code>/</code>. See <a
href="https://rclone.org/local/#paths-on-windows">local filesystem</a>
documentation for more about Windows-specific paths.</p>
<p>These paths needn't start with a leading <code>/</code> - if they
don't then they will be relative to the current directory.</p>
<h3 id="remotepathtodir">remote:path/to/dir</h3>
<p>This refers to a directory <code>path/to/dir</code> on
<code>remote:</code> as defined in the config file (configured with
<code>rclone config</code>).</p>
<h3 id="remotepathtodir-1">remote:/path/to/dir</h3>
<p>On most backends this is refers to the same directory as
<code>remote:path/to/dir</code> and that format should be preferred. On
a very small number of remotes (FTP, SFTP, Dropbox for business) this
will refer to a different directory. On these, paths without a leading
<code>/</code> will refer to your "home" directory and paths with a
leading <code>/</code> will refer to the root.</p>
<h3 id="backendpathtodir">:backend:path/to/dir</h3>
<p>This is an advanced form for creating remotes on the fly.
<code>backend</code> should be the name or prefix of a backend (the
<code>type</code> in the config file) and all the configuration for the
backend should be provided on the command line (or in environment
variables).</p>
<p>Here are some examples:</p>
<pre class="console"><code>rclone lsd --http-url https://pub.rclone.org :http:</code></pre>
<p>To list all the directories in the root of
<code>https://pub.rclone.org/</code>.</p>
<pre class="console"><code>rclone lsf --http-url https://example.com :http:path/to/dir</code></pre>
<p>To list files and directories in
<code>https://example.com/path/to/dir/</code></p>
<pre class="console"><code>rclone copy --http-url https://example.com :http:path/to/dir /tmp/dir</code></pre>
<p>To copy files and directories in
<code>https://example.com/path/to/dir</code> to
<code>/tmp/dir</code>.</p>
<pre class="console"><code>rclone copy --sftp-host example.com :sftp:path/to/dir /tmp/dir</code></pre>
<p>To copy files and directories from <code>example.com</code> in the
relative directory <code>path/to/dir</code> to <code>/tmp/dir</code>
using sftp.</p>
<h3 id="connection-strings">Connection strings</h3>
<p>The above examples can also be written using a connection string
syntax, so instead of providing the arguments as command line parameters
<code>--http-url https://pub.rclone.org</code> they are provided as part
of the remote specification as a kind of connection string.</p>
<pre class="console"><code>rclone lsd &quot;:http,url=&#39;https://pub.rclone.org&#39;:&quot;
rclone lsf &quot;:http,url=&#39;https://example.com&#39;:path/to/dir&quot;
rclone copy &quot;:http,url=&#39;https://example.com&#39;:path/to/dir&quot; /tmp/dir
rclone copy :sftp,host=example.com:path/to/dir /tmp/dir</code></pre>
<p>These can apply to modify existing remotes as well as create new
remotes with the on the fly syntax. This example is equivalent to adding
the <code>--drive-shared-with-me</code> parameter to the remote
<code>gdrive:</code>.</p>
<pre class="console"><code>rclone lsf &quot;gdrive,shared_with_me:path/to/dir&quot;</code></pre>
<p>The major advantage to using the connection string style syntax is
that it only applies to the remote, not to all the remotes of that type
of the command line. A common confusion is this attempt to copy a file
shared on google drive to the normal drive which <strong>does not
work</strong> because the <code>--drive-shared-with-me</code> flag
applies to both the source and the destination.</p>
<pre class="console"><code>rclone copy --drive-shared-with-me gdrive:shared-file.txt gdrive:</code></pre>
<p>However using the connection string syntax, this does work.</p>
<pre class="console"><code>rclone copy &quot;gdrive,shared_with_me:shared-file.txt&quot; gdrive:</code></pre>
<p>Note that the connection string only affects the options of the
immediate backend. If for example gdriveCrypt is a crypt based on
gdrive, then the following command <strong>will not work</strong> as
intended, because <code>shared_with_me</code> is ignored by the crypt
backend:</p>
<pre class="console"><code>rclone copy &quot;gdriveCrypt,shared_with_me:shared-file.txt&quot; gdriveCrypt:</code></pre>
<p>The connection strings have the following syntax</p>
<pre class="text"><code>remote,parameter=value,parameter2=value2:path/to/dir
:backend,parameter=value,parameter2=value2:path/to/dir</code></pre>
<p>If the <code>parameter</code> has a <code>:</code> or <code>,</code>
then it must be placed in quotes <code>"</code> or <code>'</code>,
so</p>
<pre class="text"><code>remote,parameter=&quot;colon:value&quot;,parameter2=&quot;comma,value&quot;:path/to/dir
:backend,parameter=&#39;colon:value&#39;,parameter2=&#39;comma,value&#39;:path/to/dir</code></pre>
<p>If a quoted value needs to include that quote, then it should be
doubled, so</p>
<pre class="text"><code>remote,parameter=&quot;with&quot;&quot;quote&quot;,parameter2=&#39;with&#39;&#39;quote&#39;:path/to/dir</code></pre>
<p>This will make <code>parameter</code> be <code>with"quote</code> and
<code>parameter2</code> be <code>with'quote</code>.</p>
<p>If you leave off the <code>=parameter</code> then rclone will
substitute <code>=true</code> which works very well with flags. For
example, to use s3 configured in the environment you could use:</p>
<pre class="console"><code>rclone lsd :s3,env_auth:</code></pre>
<p>Which is equivalent to</p>
<pre class="console"><code>rclone lsd :s3,env_auth=true:</code></pre>
<p>Note that on the command line you might need to surround these
connection strings with <code>"</code> or <code>'</code> to stop the
shell interpreting any special characters within them.</p>
<p>If you are a shell master then you'll know which strings are OK and
which aren't, but if you aren't sure then enclose them in <code>"</code>
and use <code>'</code> as the inside quote. This syntax works on all
OSes.</p>
<pre class="console"><code>rclone copy &quot;:http,url=&#39;https://example.com&#39;:path/to/dir&quot; /tmp/dir</code></pre>
<p>On Linux/macOS some characters are still interpreted inside
<code>"</code> strings in the shell (notably <code>\</code> and
<code>$</code> and <code>"</code>) so if your strings contain those you
can swap the roles of <code>"</code> and <code>'</code> thus. (This
syntax does not work on Windows.)</p>
<pre class="console"><code>rclone copy &#39;:http,url=&quot;https://example.com&quot;:path/to/dir&#39; /tmp/dir</code></pre>
<p>You can use <a
href="https://rclone.org/commands/rclone_config_string/">rclone config
string</a> to convert a remote into a connection string.</p>
<h4 id="connection-strings-config-and-logging">Connection strings,
config and logging</h4>
<p>If you supply extra configuration to a backend by command line flag,
environment variable or connection string then rclone will add a suffix
based on the hash of the config to the name of the remote, eg</p>
<pre class="console"><code>rclone -vv lsf --s3-chunk-size 20M s3:</code></pre>
<p>Has the log message</p>
<pre class="text"><code>DEBUG : s3: detected overridden config - adding &quot;{Srj1p}&quot; suffix to name</code></pre>
<p>This is so rclone can tell the modified remote apart from the
unmodified remote when caching the backends.</p>
<p>This should only be noticeable in the logs.</p>
<p>This means that on the fly backends such as</p>
<pre class="console"><code>rclone -vv lsf :s3,env_auth:</code></pre>
<p>Will get their own names</p>
<pre class="text"><code>DEBUG : :s3: detected overridden config - adding &quot;{YTu53}&quot; suffix to name</code></pre>
<h3 id="valid-remote-names">Valid remote names</h3>
<p>Remote names are case sensitive, and must adhere to the following
rules:</p>
<ul>
<li>May contain number, letter, <code>_</code>, <code>-</code>,
<code>.</code>, <code>+</code>, <code>@</code> and space.</li>
<li>May not start with <code>-</code> or space.</li>
<li>May not end with space.</li>
</ul>
<p>Starting with rclone version 1.61, any Unicode numbers and letters
are allowed, while in older versions it was limited to plain ASCII (0-9,
A-Z, a-z). If you use the same rclone configuration from different
shells, which may be configured with different character encoding, you
must be cautious to use characters that are possible to write in all of
them. This is mostly a problem on Windows, where the console
traditionally uses a non-Unicode character set - defined by the
so-called "code page".</p>
<p>Do not use single character names on Windows as it creates ambiguity
with Windows drives' names, e.g.: remote called <code>C</code> is
indistinguishable from <code>C</code> drive. Rclone will always assume
that single letter name refers to a drive.</p>
<h2 id="globalconfig">Adding global configuration to a remote</h2>
<p>It is possible to add global configuration to the remote
configuration which will be applied just before the remote is
created.</p>
<p>This can be done in two ways. The first is to use
<code>override.var = value</code> in the config file or the connection
string for a temporary change, and the second is to use
<code>global.var = value</code> in the config file or connection string
for a permanent change.</p>
<p>This is explained fully below.</p>
<h3 id="override.var">override.var</h3>
<p>This is used to override a global variable <strong>just</strong> for
the duration of the remote creation. It won't affect other remotes even
if they are created at the same time.</p>
<p>This is very useful for overriding networking config needed for just
for that remote. For example, say you have a remote which needs
<code>--no-check-certificate</code> as it is running on test
infrastructure without a proper certificate. You could supply the
<code>--no-check-certificate</code> flag to rclone, but this will affect
<strong>all</strong> the remotes. To make it just affect this remote you
use an override. You could put this in the config file:</p>
<div class="sourceCode" id="cb661"><pre
class="sourceCode ini"><code class="sourceCode ini"><span id="cb661-1"><a href="#cb661-1" aria-hidden="true" tabindex="-1"></a><span class="kw">[remote]</span></span>
<span id="cb661-2"><a href="#cb661-2" aria-hidden="true" tabindex="-1"></a><span class="dt">type </span><span class="ot">=</span><span class="st"> XXX</span></span>
<span id="cb661-3"><a href="#cb661-3" aria-hidden="true" tabindex="-1"></a><span class="dt">...</span></span>
<span id="cb661-4"><a href="#cb661-4" aria-hidden="true" tabindex="-1"></a><span class="dt">override.no_check_certificate </span><span class="ot">=</span><span class="st"> </span><span class="kw">true</span></span></code></pre></div>
<p>or use it in the connection string
<code>remote,override.no_check_certificate=true:</code> (or just
<code>remote,override.no_check_certificate:</code>).</p>
<p>Note how the global flag name loses its initial <code>--</code> and
gets <code>-</code> replaced with <code>_</code> and gets an
<code>override.</code> prefix.</p>
<p>Not all global variables make sense to be overridden like this as the
config is only applied during the remote creation. Here is a non
exhaustive list of ones which might be useful:</p>
<ul>
<li><code>bind_addr</code></li>
<li><code>ca_cert</code></li>
<li><code>client_cert</code></li>
<li><code>client_key</code></li>
<li><code>connect_timeout</code></li>
<li><code>disable_http2</code></li>
<li><code>disable_http_keep_alives</code></li>
<li><code>dump</code></li>
<li><code>expect_continue_timeout</code></li>
<li><code>headers</code></li>
<li><code>http_proxy</code></li>
<li><code>low_level_retries</code></li>
<li><code>max_connections</code></li>
<li><code>no_check_certificate</code></li>
<li><code>no_gzip</code></li>
<li><code>timeout</code></li>
<li><code>traffic_class</code></li>
<li><code>use_cookies</code></li>
<li><code>use_server_modtime</code></li>
<li><code>user_agent</code></li>
</ul>
<p>An <code>override.var</code> will override all other config methods,
but <strong>just</strong> for the duration of the creation of the
remote.</p>
<h3 id="global.var">global.var</h3>
<p>This is used to set a global variable <strong>for
everything</strong>. The global variable is set just before the remote
is created.</p>
<p>This is useful for parameters (eg sync parameters) which can't be set
as an <code>override</code>. For example, say you have a remote where
you would always like to use the <code>--checksum</code> flag. You could
supply the <code>--checksum</code> flag to rclone on every command line,
but instead you could put this in the config file:</p>
<div class="sourceCode" id="cb662"><pre
class="sourceCode ini"><code class="sourceCode ini"><span id="cb662-1"><a href="#cb662-1" aria-hidden="true" tabindex="-1"></a><span class="kw">[remote]</span></span>
<span id="cb662-2"><a href="#cb662-2" aria-hidden="true" tabindex="-1"></a><span class="dt">type </span><span class="ot">=</span><span class="st"> XXX</span></span>
<span id="cb662-3"><a href="#cb662-3" aria-hidden="true" tabindex="-1"></a><span class="dt">...</span></span>
<span id="cb662-4"><a href="#cb662-4" aria-hidden="true" tabindex="-1"></a><span class="dt">global.checksum </span><span class="ot">=</span><span class="st"> </span><span class="kw">true</span></span></code></pre></div>
<p>or use it in the connection string
<code>remote,global.checksum=true:</code> (or just
<code>remote,global.checksum:</code>). This is equivalent to using the
<code>--checksum</code> flag.</p>
<p>Note how the global flag name loses its initial <code>--</code> and
gets <code>-</code> replaced with <code>_</code> and gets a
<code>global.</code> prefix.</p>
<p>Any global variable can be set like this and it is exactly equivalent
to using the equivalent flag on the command line. This means it will
affect all uses of rclone.</p>
<p>If two remotes set the same global variable then the first one
instantiated will be overridden by the second one. A
<code>global.var</code> will override all other config methods when the
remote is created.</p>
<h2 id="quoting-and-the-shell">Quoting and the shell</h2>
<p>When you are typing commands to your computer you are using something
called the command line shell. This interprets various characters in an
OS specific way.</p>
<p>Here are some gotchas which may help users unfamiliar with the shell
rules</p>
<h3 id="linux-macos">Linux / macOS</h3>
<p>If your names have spaces or shell metacharacters (e.g.
<code>*</code>, <code>?</code>, <code>$</code>, <code>'</code>,
<code>"</code>, etc.) then you must quote them. Use single quotes
<code>'</code> by default.</p>
<pre class="console"><code>rclone copy &#39;Important files?&#39; remote:backup</code></pre>
<p>If you want to send a <code>'</code> you will need to use
<code>"</code>, e.g.</p>
<pre class="console"><code>rclone copy &quot;O&#39;Reilly Reviews&quot; remote:backup</code></pre>
<p>The rules for quoting metacharacters are complicated and if you want
the full details you'll have to consult the manual page for your
shell.</p>
<h3 id="windows-1">Windows</h3>
<p>If your names have spaces in you need to put them in <code>"</code>,
e.g.</p>
<div class="sourceCode" id="cb665"><pre
class="sourceCode bat"><code class="sourceCode dosbat"><span id="cb665-1"><a href="#cb665-1" aria-hidden="true" tabindex="-1"></a>rclone copy <span class="st">&quot;E:\folder name\folder name\folder name&quot;</span> remote:backup</span></code></pre></div>
<p>If you are using the root directory on its own then don't quote it
(see <a href="https://github.com/rclone/rclone/issues/464">#464</a> for
why), e.g.</p>
<div class="sourceCode" id="cb666"><pre
class="sourceCode bat"><code class="sourceCode dosbat"><span id="cb666-1"><a href="#cb666-1" aria-hidden="true" tabindex="-1"></a>rclone copy E:\ remote:backup</span></code></pre></div>
<h2 id="copying-files-or-directories-with-in-the-names">Copying files or
directories with <code>:</code> in the names</h2>
<p>rclone uses <code>:</code> to mark a remote name. This is, however, a
valid filename component in non-Windows OSes. The remote name parser
will only search for a <code>:</code> up to the first <code>/</code> so
if you need to act on a file or directory like this then use the full
path starting with a <code>/</code>, or use <code>./</code> as a current
directory prefix.</p>
<p>So to sync a directory called <code>sync:me</code> to a remote called
<code>remote:</code> use</p>
<pre class="console"><code>rclone sync --interactive ./sync:me remote:path</code></pre>
<p>or</p>
<pre class="console"><code>rclone sync --interactive /full/path/to/sync:me remote:path</code></pre>
<h2 id="server-side-copy">Server-side copy</h2>
<p>Most remotes (but not all - see <a
href="https://rclone.org/overview/#optional-features">the overview</a>)
support server-side copy.</p>
<p>This means if you want to copy one folder to another then rclone
won't download all the files and re-upload them; it will instruct the
server to copy them in place.</p>
<p>Eg</p>
<pre class="console"><code>rclone copy s3:oldbucket s3:newbucket</code></pre>
<p>Will copy the contents of <code>oldbucket</code> to
<code>newbucket</code> without downloading and re-uploading.</p>
<p>Remotes which don't support server-side copy <strong>will</strong>
download and re-upload in this case.</p>
<p>Server-side copies are used with <code>sync</code> and
<code>copy</code> and will be identified in the log when using the
<code>-v</code> flag. The <code>move</code> command may also use them if
remote doesn't support server-side move directly. This is done by
issuing a server-side copy then a delete which is much quicker than a
download and re-upload.</p>
<p>Server-side copies will only be attempted if the remote names are the
same.</p>
<p>This can be used when scripting to make aged backups efficiently,
e.g.</p>
<pre class="console"><code>rclone sync --interactive remote:current-backup remote:previous-backup
rclone sync --interactive /path/to/files remote:current-backup</code></pre>
<h2 id="metadata">Metadata support</h2>
<p>Metadata is data about a file (or directory) which isn't the contents
of the file (or directory). Normally rclone only preserves the
modification time and the content (MIME) type where possible.</p>
<p>Rclone supports preserving all the available metadata on files and
directories when using the <code>--metadata</code> or <code>-M</code>
flag.</p>
<p>Exactly what metadata is supported and what that support means
depends on the backend. Backends that support metadata have a metadata
section in their docs and are listed in the <a
href="https://rclone.org/overview/#features">features table</a> (Eg <a
href="https://rclone.org/local/#metadata">local</a>, <a
href="/s3/#metadata">s3</a>)</p>
<p>Some backends don't support metadata, some only support metadata on
files and some support metadata on both files and directories.</p>
<p>Rclone only supports a one-time sync of metadata. This means that
metadata will be synced from the source object to the destination object
only when the source object has changed and needs to be re-uploaded. If
the metadata subsequently changes on the source object without changing
the object itself then it won't be synced to the destination object.
This is in line with the way rclone syncs <code>Content-Type</code>
without the <code>--metadata</code> flag.</p>
<p>Using <code>--metadata</code> when syncing from local to local will
preserve file attributes such as file mode, owner, extended attributes
(not Windows).</p>
<p>Note that arbitrary metadata may be added to objects using the
<code>--metadata-set key=value</code> flag when the object is first
uploaded. This flag can be repeated as many times as necessary.</p>
<p>The <a href="#metadata-mapper">--metadata-mapper</a> flag can be used
to pass the name of a program in which can transform metadata when it is
being copied from source to destination.</p>
<p>Rclone supports <code>--metadata-set</code> and
<code>--metadata-mapper</code> when doing server-side <code>Move</code>
and server-side <code>Copy</code>, but not when doing server side
<code>DirMove</code> (renaming a directory) as this would involve
recursing into the directory. Note that you can disable
<code>DirMove</code> with <code>--disable DirMove</code> and rclone will
revert back to using <code>Move</code> for each individual object where
<code>--metadata-set</code> and <code>--metadata-mapper</code> are
supported.</p>
<h3 id="types-of-metadata">Types of metadata</h3>
<p>Metadata is divided into two type. System metadata and User
metadata.</p>
<p>Metadata which the backend uses itself is called system metadata. For
example on the local backend the system metadata <code>uid</code> will
store the user ID of the file when used on a unix based platform.</p>
<p>Arbitrary metadata is called user metadata and this can be set
however is desired.</p>
<p>When objects are copied from backend to backend, they will attempt to
interpret system metadata if it is supplied. Metadata may change from
being user metadata to system metadata as objects are copied between
different backends. For example copying an object from s3 sets the
<code>content-type</code> metadata. In a backend which understands this
(like <code>azureblob</code>) this will become the Content-Type of the
object. In a backend which doesn't understand this (like the
<code>local</code> backend) this will become user metadata. However
should the local object be copied back to s3, the Content-Type will be
set correctly.</p>
<h3 id="metadata-framework">Metadata framework</h3>
<p>Rclone implements a metadata framework which can read metadata from
an object and write it to the object when (and only when) it is being
uploaded.</p>
<p>This metadata is stored as a dictionary with string keys and string
values.</p>
<p>There are some limits on the names of the keys (these may be
clarified further in the future).</p>
<ul>
<li>must be lower case</li>
<li>may be <code>a-z</code> <code>0-9</code> containing <code>.</code>
<code>-</code> or <code>_</code></li>
<li>length is backend dependent</li>
</ul>
<p>Each backend can provide system metadata that it understands. Some
backends can also store arbitrary user metadata.</p>
<p>Where possible the key names are standardized, so, for example, it is
possible to copy object metadata from s3 to azureblob for example and
metadata will be translated appropriately.</p>
<p>Some backends have limits on the size of the metadata and rclone will
give errors on upload if they are exceeded.</p>
<h3 id="metadata-preservation">Metadata preservation</h3>
<p>The goal of the implementation is to</p>
<ol type="1">
<li>Preserve metadata if at all possible</li>
<li>Interpret metadata if at all possible</li>
</ol>
<p>The consequences of 1 is that you can copy an S3 object to a local
disk then back to S3 losslessly. Likewise you can copy a local file with
file attributes and xattrs from local disk to s3 and back again
losslessly.</p>
<p>The consequence of 2 is that you can copy an S3 object with metadata
to Azureblob (say) and have the metadata appear on the Azureblob object
also.</p>
<h3 id="standard-system-metadata">Standard system metadata</h3>
<p>Here is a table of standard system metadata which, if appropriate, a
backend may implement.</p>

<p>The metadata keys <code>mtime</code> and <code>content-type</code>
will take precedence if supplied in the metadata over reading the
<code>Content-Type</code> or modification time of the source object.</p>
<p>Hashes are not included in system metadata as there is a well defined
way of reading those already.</p>
<h2 id="options-97">Options</h2>
<p>Rclone has a number of options to control its behaviour. These are
documented below, and in the <a href="/flags">flags</a> page.</p>
<p>Options that take parameters can have the values passed in two ways,
<code>--option=value</code> or <code>--option value</code>. However
boolean (true/false) options behave slightly differently to the other
options in that <code>--boolean</code> sets the option to
<code>true</code> and the absence of the flag sets it to
<code>false</code>. It is also possible to specify
<code>--boolean=false</code> or <code>--boolean=true</code>. Note that
<code>--boolean false</code> is not valid - this is parsed as
<code>--boolean</code> and the <code>false</code> is parsed as an extra
command line argument for rclone.</p>
<p>String values that are recognized as special identifiers, e.g. the
name of the log level to set with option <code>--log-level</code>, are
case insensitive, e.g. <code>--log-level ERROR</code> and
<code>--log-level error</code> are identical.</p>
<p>Options documented to take a <code>stringArray</code> parameter
accept multiple values. To pass more than one value, repeat the option;
for example: <code>--include value1 --include value2</code>. Other
options may only accept a single value, and should only be specified
once, but where the specified parameter may indicate a list of values
separated by space or comma. Such options are documented to take a
<code>CommaSepList</code> parameter, if comma separated, and
<code>SpaceSepList</code> if space separated, although some may also
have different parameters such as <code>DumpFlags</code> or just
<code>string</code> and the help text explains that this will be
interpreted as a list.</p>
<p>Floating-point values with fractional part must use period
(<code>.</code>) as decimal separator, common in English-speaking
countries, regardless of your configured system locale. Parameter type
<code>float</code> accepts decimal and hexadecimal floating-point
numbers as defined by the Go syntax for <a
href="https://go.dev/ref/spec#Floating-point_literals">floating-point
literals</a>.</p>
<h3 id="time-options">Time and duration options</h3>
<p>Options that take a <code>Time</code> or <code>Duration</code>
parameter must be specified as a formatted string describing an absolute
or relative time. Note that both <code>Time</code> and
<code>Duration</code> parameter types can be expressed as either
absolute or relative time, just with different interpretations, e.g. a
relative time will be treated as an offset from the current time when
passed as a <code>Time</code> value.</p>
<p>An absolute time can be specified as a string in one of the following
formats:</p>
<ul>
<li>RFC3339 - e.g. <code>2006-01-02T15:04:05Z</code> or
<code>2006-01-02T15:04:05+07:00</code></li>
<li>ISO8601 Date and time, local timezone -
<code>2006-01-02T15:04:05</code></li>
<li>ISO8601 Date and time, local timezone -
<code>2006-01-02 15:04:05</code></li>
<li>ISO8601 Date - <code>2006-01-02</code> (YYYY-MM-DD)</li>
</ul>
<p>A relative time is a string with a, possibly signed, sequence of
decimal numbers, each with optional fraction, and each with a unit
suffix. If the string only contains a single number, then the unit
suffix is optional and will default to seconds, i.e. a plain decimal
value will be treated as a number of seconds. The following suffixes are
valid:</p>
<ul>
<li><code>ms</code> - Milliseconds</li>
<li><code>s</code> - Seconds</li>
<li><code>m</code> - Minutes</li>
<li><code>h</code> - Hours</li>
<li><code>d</code> - Days</li>
<li><code>w</code> - Weeks</li>
<li><code>M</code> - Months</li>
<li><code>y</code> - Years</li>
</ul>
<p>Examples: "10", "300ms", "-1.5h" or "2h45m".</p>
<h3 id="size-options">Size options</h3>
<p>Options that take a SizeSuffix parameter can be specified as an
integer value, which will then be assumed to represent a KiB value
(multiples of 1024 bytes) by default. The interpretation can be changed
by appending a suffix: <code>B</code> for Byte, <code>K</code> for KiB,
<code>M</code> for MiB, <code>G</code> for GiB, <code>T</code> for TiB
and <code>P</code> for PiB. These are the binary units, e.g. 1, 2**10,
2**20, 2**30 respectively.</p>
<p>See also <a href="#human-readable">--human-readable</a>.</p>
<h2 id="main-options">Main options</h2>
<h3 id="backup-dir-string">--backup-dir string</h3>
<p>When using <a
href="https://rclone.org/commands/rclone_sync/">sync</a>, <a
href="https://rclone.org/commands/rclone_copy/">copy</a> or <a
href="https://rclone.org/commands/rclone_move/">move</a>, any files
which would have been overwritten or deleted are moved in their original
hierarchy into this directory.</p>
<p>If <code>--suffix</code> is set, then the moved files will have the
suffix added to them. If there is a file with the same path (after the
suffix has been added) in the directory, then it will be
overwritten.</p>
<p>The remote in use must support server-side move or copy and you must
use the same remote as the destination of the sync. The backup directory
must not overlap the destination directory without it being excluded by
a filter rule.</p>
<p>For example</p>
<pre class="console"><code>rclone sync --interactive /path/to/local remote:current --backup-dir remote:old</code></pre>
<p>will sync <code>/path/to/local</code> to <code>remote:current</code>,
but for any files which would have been updated or deleted will be
stored in <code>remote:old</code>.</p>
<p>If running rclone from a script you might want to use today's date as
the directory name passed to <code>--backup-dir</code> to store the old
files, or you might want to pass <code>--suffix</code> with today's
date. This can be done with <code>--suffix $(date +%F)</code> in bash,
and <code>--suffix $(Get-Date -Format 'yyyy-MM-dd')</code> in
PowerShell.</p>
<p>See <code>--compare-dest</code> and <code>--copy-dest</code>.</p>
<h3 id="bind-string">--bind string</h3>
<p>Local address to bind to for outgoing connections. This can be an
IPv4 address (1.2.3.4), an IPv6 address (1234::789A) or host name. If
the host name doesn't resolve or resolves to more than one IP address it
will give an error.</p>
<p>You can use <code>--bind 0.0.0.0</code> to force rclone to use IPv4
addresses and <code>--bind ::0</code> to force rclone to use IPv6
addresses.</p>
<h3 id="bwlimit-bwtimetable">--bwlimit BwTimetable</h3>
<p>This option controls the bandwidth limit. For example</p>
<pre class="text"><code>--bwlimit 10M</code></pre>
<p>would mean limit the upload and download bandwidth to 10 MiB/s.
<strong>NB</strong> this is <strong>bytes</strong> per second not
<strong>bits</strong> per second. To use a single limit, specify the
desired bandwidth in KiB/s, or use a suffix B|K|M|G|T|P. The default is
<code>0</code> which means to not limit bandwidth.</p>
<p>The upload and download bandwidth can be specified separately, as
<code>--bwlimit UP:DOWN</code>, so</p>
<pre class="text"><code>--bwlimit 10M:100k</code></pre>
<p>would mean limit the upload bandwidth to 10 MiB/s and the download
bandwidth to 100 KiB/s. Either limit can be "off" meaning no limit, so
to just limit the upload bandwidth you would use</p>
<pre class="text"><code>--bwlimit 10M:off</code></pre>
<p>this would limit the upload bandwidth to 10 MiB/s but the download
bandwidth would be unlimited.</p>
<p>When specified as above the bandwidth limits last for the duration of
run of the rclone binary.</p>
<p>It is also possible to specify a "timetable" of limits, which will
cause certain limits to be applied at certain times. To specify a
timetable, format your entries as
<code>WEEKDAY-HH:MM,BANDWIDTH WEEKDAY-HH:MM,BANDWIDTH...</code> where:
<code>WEEKDAY</code> is optional element.</p>
<ul>
<li><code>BANDWIDTH</code> can be a single number, e.g.<code>100k</code>
or a pair of numbers for upload:download, e.g.<code>10M:1M</code>.</li>
<li><code>WEEKDAY</code> can be written as the whole word or only using
the first 3 characters. It is optional.</li>
<li><code>HH:MM</code> is an hour from 00:00 to 23:59.</li>
</ul>
<p>Entries can be separated by spaces or semicolons.</p>
<p><strong>Note:</strong> Semicolons can be used as separators instead
of spaces to avoid parsing issues in environments like Docker.</p>
<p>An example of a typical timetable to avoid link saturation during
daytime working hours could be:</p>
<p>Using spaces as separators:
<code>--bwlimit "08:00,512k 12:00,10M 13:00,512k 18:00,30M 23:00,off"</code></p>
<p>Using semicolons as separators:
<code>--bwlimit "08:00,512k;12:00,10M;13:00,512k;18:00,30M;23:00,off"</code></p>
<p>In these examples, the transfer bandwidth will be set to 512 KiB/s at
8am every day. At noon, it will rise to 10 MiB/s, and drop back to 512
KiB/sec at 1pm. At 6pm, the bandwidth limit will be set to 30 MiB/s, and
at 11pm it will be completely disabled (full speed). Anything between
11pm and 8am will remain unlimited.</p>
<p>An example of timetable with <code>WEEKDAY</code> could be:</p>
<p>Using spaces as separators:
<code>--bwlimit "Mon-00:00,512 Fri-23:59,10M Sat-10:00,1M Sun-20:00,off"</code></p>
<p>Using semicolons as separators:
<code>--bwlimit "Mon-00:00,512;Fri-23:59,10M;Sat-10:00,1M;Sun-20:00,off"</code></p>
<p>It means that, the transfer bandwidth will be set to 512 KiB/s on
Monday. It will rise to 10 MiB/s before the end of Friday. At 10:00 on
Saturday it will be set to 1 MiB/s. From 20:00 on Sunday it will be
unlimited.</p>
<p>Timeslots without <code>WEEKDAY</code> are extended to the whole
week. So this example:</p>
<pre class="text"><code>--bwlimit &quot;Mon-00:00,512 12:00,1M Sun-20:00,off&quot;</code></pre>
<p>Is equivalent to this:</p>
<pre class="text"><code>--bwlimit &quot;Mon-00:00,512Mon-12:00,1M Tue-12:00,1M Wed-12:00,1M Thu-12:00,1M Fri-12:00,1M Sat-12:00,1M Sun-12:00,1M Sun-20:00,off&quot;</code></pre>
<p>Bandwidth limit apply to the data transfer for all backends. For most
backends the directory listing bandwidth is also included (exceptions
being the non HTTP backends, <code>ftp</code>, <code>sftp</code> and
<code>storj</code>).</p>
<p>Note that the units are <strong>Byte/s</strong>, not
<strong>bit/s</strong>. Typically connections are measured in bit/s - to
convert divide by 8. For example, let's say you have a 10 Mbit/s
connection and you wish rclone to use half of it - 5 Mbit/s. This is 5/8
= 0.625 MiB/s so you would use a <code>--bwlimit 0.625M</code> parameter
for rclone.</p>
<p>On Unix systems (Linux, macOS, …) the bandwidth limiter can be
toggled by sending a <code>SIGUSR2</code> signal to rclone. This allows
to remove the limitations of a long running rclone transfer and to
restore it back to the value specified with <code>--bwlimit</code>
quickly when needed. Assuming there is only one rclone instance running,
you can toggle the limiter like this:</p>
<pre class="console"><code>kill -SIGUSR2 $(pidof rclone)</code></pre>
<p>If you configure rclone with a <a href="/rc">remote control</a> then
you can use change the bwlimit dynamically:</p>
<pre class="console"><code>rclone rc core/bwlimit rate=1M</code></pre>
<h3 id="bwlimit-file-bwtimetable">--bwlimit-file BwTimetable</h3>
<p>This option controls per file bandwidth limit. For the options see
the <code>--bwlimit</code> flag.</p>
<p>For example use this to allow no transfers to be faster than 1
MiB/s</p>
<pre class="text"><code>--bwlimit-file 1M</code></pre>
<p>This can be used in conjunction with <code>--bwlimit</code>.</p>
<p>Note that if a schedule is provided the file will use the schedule in
effect at the start of the transfer.</p>
<h3 id="buffer-size-sizesuffix">--buffer-size SizeSuffix</h3>
<p>Use this sized buffer to speed up file transfers. Each
<code>--transfer</code> will use this much memory for buffering.</p>
<p>When using <code>mount</code> or <code>cmount</code> each open file
descriptor will use this much memory for buffering. See the <a
href="https://rclone.org/commands/rclone_mount/#file-buffering">mount</a>
documentation for more details.</p>
<p>Set to <code>0</code> to disable the buffering for the minimum memory
usage.</p>
<p>Note that the memory allocation of the buffers is influenced by the
<a href="#use-mmap">--use-mmap</a> flag.</p>
<h3 id="cache-dir-string">--cache-dir string</h3>
<p>Specify the directory rclone will use for caching, to override the
default.</p>
<p>Default value is depending on operating system:</p>
<ul>
<li>Windows <code>%LocalAppData%\rclone</code>, if
<code>LocalAppData</code> is defined.</li>
<li>macOS <code>$HOME/Library/Caches/rclone</code> if <code>HOME</code>
is defined.</li>
<li>Unix <code>$XDG_CACHE_HOME/rclone</code> if
<code>XDG_CACHE_HOME</code> is defined, else
<code>$HOME/.cache/rclone</code> if <code>HOME</code> is defined.</li>
<li>Fallback (on all OS) to <code>$TMPDIR/rclone</code>, where
<code>TMPDIR</code> is the value from <a
href="#temp-dir-string">--temp-dir</a>.</li>
</ul>
<p>You can use the <a
href="https://rclone.org/commands/rclone_config_paths/">config paths</a>
command to see the current value.</p>
<p>Cache directory is heavily used by the <a
href="https://rclone.org/commands/rclone_mount/#vfs-file-caching">VFS
File Caching</a> mount feature, but also by <a
href="https://rclone.org/commands/rclone_serve/">serve</a>, <a
href="/gui">GUI</a> and other parts of rclone.</p>
<h3 id="check-first">--check-first</h3>
<p>If this flag is set then in a <a
href="https://rclone.org/commands/rclone_sync/">sync</a>, <a
href="https://rclone.org/commands/rclone_copy/">copy</a> or <a
href="https://rclone.org/commands/rclone_move/">move</a>, rclone will do
all the checks to see whether files need to be transferred before doing
any of the transfers. Normally rclone would start running transfers as
soon as possible.</p>
<p>This flag can be useful on IO limited systems where transfers
interfere with checking.</p>
<p>It can also be useful to ensure perfect ordering when using
<code>--order-by</code>.</p>
<p>If both <code>--check-first</code> and <code>--order-by</code> are
set when doing <code>rclone move</code> then rclone will use the
transfer thread to delete source files which don't need transferring.
This will enable perfect ordering of the transfers and deletes but will
cause the transfer stats to have more items in than expected.</p>
<p>Using this flag can use more memory as it effectively sets
<code>--max-backlog</code> to infinite. This means that all the info on
the objects to transfer is held in memory before the transfers
start.</p>
<h3 id="checkers-int">--checkers int</h3>
<p>Originally controlling just the number of file checkers to run in
parallel, e.g. by <code>rclone copy</code>. Now a fairly universal
parallelism control used by <code>rclone</code> in several places.</p>
<p>Note: checkers do the equality checking of files during a sync. For
some storage systems (e.g. S3, Swift, Dropbox) this can take a
significant amount of time so they are run in parallel.</p>
<p>The default is to run 8 checkers in parallel. However, in case of
slow-reacting backends you may need to lower (rather than increase) this
default by setting <code>--checkers</code> to 4 or less threads. This is
especially advised if you are experiencing backend server crashes during
file checking phase (e.g. on subsequent or top-up backups where little
or no file copying is done and checking takes up most of the time).
Increase this setting only with utmost care, while monitoring your
server health and file checking throughput.</p>
<h3 id="c---checksum">-c, --checksum</h3>
<p>Normally rclone will look at modification time and size of files to
see if they are equal. If you set this flag then rclone will check the
file hash and size to determine if files are equal.</p>
<p>This is useful when the remote doesn't support setting modified time
and a more accurate sync is desired than just checking the file
size.</p>
<p>This is very useful when transferring between remotes which store the
same hash type on the object, e.g. Drive and Swift. For details of which
remotes support which hash type see the table in the <a
href="https://rclone.org/overview/">overview section</a>.</p>
<p>Eg <code>rclone --checksum sync s3:/bucket swift:/bucket</code> would
run much quicker than without the <code>--checksum</code> flag.</p>
<p>When using this flag, rclone won't update mtimes of remote files if
they are incorrect as it would normally.</p>
<h3 id="color-autoneveralways">--color AUTO|NEVER|ALWAYS</h3>
<p>Specify when colors (and other ANSI codes) should be added to the
output.</p>
<p><code>AUTO</code> only allows ANSI codes when the output is a
terminal. This is the default.</p>
<p><code>NEVER</code> never allow ANSI codes.</p>
<p><code>ALWAYS</code> always add ANSI codes, regardless of the output
format (terminal or file).</p>
<h3 id="compare-dest-stringarray">--compare-dest stringArray</h3>
<p>When using <a
href="https://rclone.org/commands/rclone_sync/">sync</a>, <a
href="https://rclone.org/commands/rclone_copy/">copy</a> or <a
href="https://rclone.org/commands/rclone_move/">move</a>, the specified
paths are checked in addition to the destination for files. If a file
identical to the source is found, that file is <strong>not</strong>
copied from source. This is useful to copy just files that have changed
since the last backup.</p>
<p>You must use the same remote as the destination of the sync. The
compare directory must not overlap the destination directory.</p>
<p>See <code>--copy-dest</code> and <code>--backup-dir</code>.</p>
<h3 id="config-string">--config string</h3>
<p>Specify the location of the rclone configuration file, to override
the default. E.g. <code>rclone config --config="rclone.conf"</code>.</p>
<p>The exact default is a bit complex to describe, due to changes
introduced through different versions of rclone while preserving
backwards compatibility, but in most cases it is as simple as:</p>
<ul>
<li><code>%APPDATA%/rclone/rclone.conf</code> on Windows</li>
<li><code>~/.config/rclone/rclone.conf</code> on other</li>
</ul>
<p>The complete logic is as follows: Rclone will look for an existing
configuration file in any of the following locations, in priority
order:</p>
<ol type="1">
<li><code>rclone.conf</code> (in program directory, where rclone
executable is)</li>
<li><code>%APPDATA%/rclone/rclone.conf</code> (only on Windows)</li>
<li><code>$XDG_CONFIG_HOME/rclone/rclone.conf</code> (on all systems,
including Windows)</li>
<li><code>~/.config/rclone/rclone.conf</code> (see below for explanation
of ~ symbol)</li>
<li><code>~/.rclone.conf</code></li>
</ol>
<p>If no existing configuration file is found, then a new one will be
created in the following location:</p>
<ul>
<li>On Windows: Location 2 listed above, except in the unlikely event
that <code>APPDATA</code> is not defined, then location 4 is used
instead.</li>
<li>On Unix: Location 3 if <code>XDG_CONFIG_HOME</code> is defined, else
location 4.</li>
<li>Fallback to location 5 (on all OS), when the rclone directory cannot
be created, but if also a home directory was not found then path
<code>.rclone.conf</code> relative to current working directory will be
used as a final resort.</li>
</ul>
<p>The <code>~</code> symbol in paths above represent the home directory
of the current user on any OS, and the value is defined as
following:</p>
<ul>
<li>On Windows: <code>%HOME%</code> if defined, else
<code>%USERPROFILE%</code>, or else
<code>%HOMEDRIVE%\%HOMEPATH%</code>.</li>
<li>On Unix: <code>$HOME</code> if defined, else by looking up current
user in OS-specific user database (e.g. passwd file), or else use the
result from shell command <code>cd &amp;&amp; pwd</code>.</li>
</ul>
<p>If you run <code>rclone config file</code> you will see where the
default location is for you. Running <code>rclone config touch</code>
will ensure a configuration file exists, creating an empty one in the
default location if there is none.</p>
<p>The fact that an existing file <code>rclone.conf</code> in the same
directory as the rclone executable is always preferred, means that it is
easy to run in "portable" mode by downloading rclone executable to a
writable directory and then create an empty file
<code>rclone.conf</code> in the same directory.</p>
<p>If the location is set to empty string <code>""</code> or path to a
file with name <code>notfound</code>, or the os null device represented
by value <code>NUL</code> on Windows and <code>/dev/null</code> on Unix
systems, then rclone will keep the configuration file in memory
only.</p>
<p>You may see a log message "Config file not found - using defaults" if
there is no configuration file. This can be supressed, e.g. if you are
using rclone entirely with <a
href="https://rclone.org/docs/#backend-path-to-dir">on the fly
remotes</a>, by using memory-only configuration file or by creating an
empty configuration file, as described above.</p>
<p>The file format is basic <a
href="https://en.wikipedia.org/wiki/INI_file#Format">INI</a>: Sections
of text, led by a <code>[section]</code> header and followed by
<code>key=value</code> entries on separate lines. In rclone each remote
is represented by its own section, where the section name defines the
name of the remote. Options are specified as the <code>key=value</code>
entries, where the key is the option name without the
<code>--backend-</code> prefix, in lowercase and with <code>_</code>
instead of <code>-</code>. E.g. option <code>--mega-hard-delete</code>
corresponds to key <code>hard_delete</code>. Only backend options can be
specified. A special, and required, key <code>type</code> identifies the
<a href="https://rclone.org/overview/">storage system</a>, where the
value is the internal lowercase name as returned by command
<code>rclone help backends</code>. Comments are indicated by
<code>;</code> or <code>#</code> at the beginning of a line.</p>
<p>Example:</p>
<div class="sourceCode" id="cb680"><pre
class="sourceCode ini"><code class="sourceCode ini"><span id="cb680-1"><a href="#cb680-1" aria-hidden="true" tabindex="-1"></a><span class="kw">[megaremote]</span></span>
<span id="cb680-2"><a href="#cb680-2" aria-hidden="true" tabindex="-1"></a><span class="dt">type </span><span class="ot">=</span><span class="st"> mega</span></span>
<span id="cb680-3"><a href="#cb680-3" aria-hidden="true" tabindex="-1"></a><span class="dt">user </span><span class="ot">=</span><span class="st"> you@example.com</span></span>
<span id="cb680-4"><a href="#cb680-4" aria-hidden="true" tabindex="-1"></a><span class="dt">pass </span><span class="ot">=</span><span class="st"> PDPcQVVjVtzFY-GTdDFozqBhTdsPg3qH</span></span></code></pre></div>
<p>Note that passwords are in <a
href="https://rclone.org/commands/rclone_obscure/">obscured</a> form.
Also, many storage systems uses token-based authentication instead of
passwords, and this requires additional steps. It is easier, and safer,
to use the interactive command <code>rclone config</code> instead of
manually editing the configuration file.</p>
<p>The configuration file will typically contain login information, and
should therefore have restricted permissions so that only the current
user can read it. Rclone tries to ensure this when it writes the file.
You may also choose to <a href="#configuration-encryption">encrypt</a>
the file.</p>
<p>When token-based authentication are used, the configuration file must
be writable, because rclone needs to update the tokens inside it.</p>
<p>To reduce risk of corrupting an existing configuration file, rclone
will not write directly to it when saving changes. Instead it will first
write to a new, temporary, file. If a configuration file already
existed, it will (on Unix systems) try to mirror its permissions to the
new file. Then it will rename the existing file to a temporary name as
backup. Next, rclone will rename the new file to the correct name,
before finally cleaning up by deleting the backup file.</p>
<p>If the configuration file path used by rclone is a symbolic link,
then this will be evaluated and rclone will write to the resolved path,
instead of overwriting the symbolic link. Temporary files used in the
process (described above) will be written to the same parent directory
as that of the resolved configuration file, but if this directory is
also a symbolic link it will not be resolved and the temporary files
will be written to the location of the directory symbolic link.</p>
<h3 id="contimeout-duration">--contimeout Duration</h3>
<p>Set the connection timeout. This should be in go time format which
looks like <code>5s</code> for 5 seconds, <code>10m</code> for 10
minutes, or <code>3h30m</code>.</p>
<p>The connection timeout is the amount of time rclone will wait for a
connection to go through to a remote object storage system. It is
<code>1m</code> by default.</p>
<h3 id="copy-dest-stringarray">--copy-dest stringArray</h3>
<p>When using <a
href="https://rclone.org/commands/rclone_sync/">sync</a>, <a
href="https://rclone.org/commands/rclone_copy/">copy</a> or <a
href="https://rclone.org/commands/rclone_move/">move</a>, the specified
paths are checked in addition to the destination for files. This part is
the same as <code>--compare-dest</code>, but the difference is that with
<code>--copy-dest</code>, if a file identical to the source is found,
that file is server-side copied from the specified paths to the
destination. This is useful for incremental backup.</p>
<p>The remote in use must support server-side copy and you must use the
same remote as the destination of the sync. The compare directory must
not overlap the destination directory.</p>
<p>See <code>--compare-dest</code> and <code>--backup-dir</code>.</p>
<h3
id="dedupe-mode-interactiveskipfirstnewestoldestlargestsmallestrenamelist">--dedupe-mode
interactive|skip|first|newest|oldest|largest|smallest|rename|list</h3>
<p>Mode to run dedupe command in. One of <code>interactive</code>,
<code>skip</code>, <code>first</code>, <code>newest</code>,
<code>oldest</code>, <code>largest</code>, <code>smallest</code>,
<code>rename</code> <code>list</code>. The default is
<code>interactive</code>. See the <a
href="https://rclone.org/commands/rclone_dedupe/">dedupe</a> command for
more information as to what these options mean.</p>
<h3 id="default-time-time">--default-time Time</h3>
<p>If a file or directory does have a modification time rclone can read
then rclone will display this fixed time instead.</p>
<p>The default is <code>2000-01-01 00:00:00 UTC</code>. This can be
configured in any of the ways shown in <a href="#time-options">time
options</a>.</p>
<p>For example <code>--default-time 2020-06-01</code> to set the default
time to the 1st of June 2020 or <code>--default-time 0s</code> to set
the default time to the time rclone started up.</p>
<h3 id="disable-string">--disable string</h3>
<p>This disables a comma separated list of optional features. For
example to disable server-side move and server-side copy use:</p>
<pre class="text"><code>--disable move,copy</code></pre>
<p>The features can be put in any case.</p>
<p>To see a list of which features can be disabled use:</p>
<pre class="text"><code>--disable help</code></pre>
<p>The features a remote has can be seen in JSON format with:</p>
<pre class="console"><code>rclone backend features remote:</code></pre>
<p>See the overview <a
href="https://rclone.org/overview/#features">features</a> and <a
href="https://rclone.org/overview/#optional-features">optional
features</a> to get an idea of which feature does what.</p>
<p>Note that some features can be set to <code>true</code> if they are
<code>true</code>/<code>false</code> feature flag features by prefixing
them with <code>!</code>. For example the <code>CaseInsensitive</code>
feature can be forced to <code>false</code> with
<code>--disable CaseInsensitive</code> and forced to <code>true</code>
with <code>--disable '!CaseInsensitive'</code>. In general it isn't a
good idea doing this but it may be useful in extremis.</p>
<p>(Note that <code>!</code> is a shell command which you will need to
escape with single quotes or a backslash on unix like platforms.)</p>
<p>This flag can be useful for debugging and in exceptional
circumstances (e.g. Google Drive limiting the total volume of
server-side copies to 100 GiB/day).</p>
<h3 id="disable-http2">--disable-http2</h3>
<p>This stops rclone from trying to use HTTP/2 if available. This can
sometimes speed up transfers due to a <a
href="https://github.com/golang/go/issues/37373">problem in the Go
standard library</a>.</p>
<h3 id="dscp-string">--dscp string</h3>
<p>Specify a DSCP value or name to use in connections. This could help
QoS system to identify traffic class. BE, EF, DF, LE, CSx and AFxx are
allowed.</p>
<p>See the description of <a
href="https://en.wikipedia.org/wiki/Differentiated_services">differentiated
services</a> to get an idea of this field. Setting this to 1 (LE) to
identify the flow to SCAVENGER class can avoid occupying too much
bandwidth in a network with DiffServ support (<a
href="https://tools.ietf.org/html/rfc8622">RFC 8622</a>).</p>
<p>For example, if you configured QoS on router to handle LE properly.
Running:</p>
<pre class="console"><code>rclone copy --dscp LE from:/from to:/to</code></pre>
<p>would make the priority lower than usual internet flows.</p>
<p>This option has no effect on Windows (see <a
href="https://github.com/golang/go/issues/42728">golang/go#42728</a>).</p>
<h3 id="n---dry-run">-n, --dry-run</h3>
<p>Do a trial run with no permanent changes. Use this to see what rclone
would do without actually doing it. Useful when setting up the <a
href="https://rclone.org/commands/rclone_sync/">sync</a> command which
deletes files in the destination.</p>
<h3 id="expect-continue-timeout-duration">--expect-continue-timeout
Duration</h3>
<p>This specifies the amount of time to wait for a server's first
response headers after fully writing the request headers if the request
has an "Expect: 100-continue" header. Not all backends support using
this.</p>
<p>Zero means no timeout and causes the body to be sent immediately,
without waiting for the server to approve. This time does not include
the time to send the request header.</p>
<p>The default is <code>1s</code>. Set to <code>0</code> to disable.</p>
<h3 id="error-on-no-transfer">--error-on-no-transfer</h3>
<p>By default, rclone will exit with return code 0 if there were no
errors.</p>
<p>This option allows rclone to return exit code 9 if no files were
transferred between the source and destination. This allows using rclone
in scripts, and triggering follow-on actions if data was copied, or
skipping if not.</p>
<p>NB: Enabling this option turns a usually non-fatal error into a
potentially fatal one - please check and adjust your scripts
accordingly!</p>
<h3 id="fix-case">--fix-case</h3>
<p>Normally, a sync to a case insensitive dest (such as macOS / Windows)
will not result in a matching filename if the source and dest filenames
have casing differences but are otherwise identical. For example,
syncing <code>hello.txt</code> to <code>HELLO.txt</code> will normally
result in the dest filename remaining <code>HELLO.txt</code>. If
<code>--fix-case</code> is set, then <code>HELLO.txt</code> will be
renamed to <code>hello.txt</code> to match the source.</p>
<p>NB:</p>
<ul>
<li>directory names with incorrect casing will also be fixed</li>
<li><code>--fix-case</code> will be ignored if <code>--immutable</code>
is set</li>
<li>using <code>--local-case-sensitive</code> instead is not advisable;
it will cause <code>HELLO.txt</code> to get deleted!</li>
<li>the old dest filename must not be excluded by filters. Be especially
careful with <a
href="https://rclone.org/filtering/#files-from-read-list-of-source-file-names"><code>--files-from</code></a>,
which does not respect <a
href="https://rclone.org/filtering/#ignore-case-make-searches-case-insensitive"><code>--ignore-case</code></a>!</li>
<li>on remotes that do not support server-side move,
<code>--fix-case</code> will require downloading the file and
re-uploading it. To avoid this, do not use <code>--fix-case</code>.</li>
</ul>
<h3 id="fs-cache-expire-duration-duration">--fs-cache-expire-duration
Duration</h3>
<p>When using rclone via the API rclone caches created remotes for 5
minutes by default in the "fs cache". This means that if you do repeated
actions on the same remote then rclone won't have to build it again from
scratch, which makes it more efficient.</p>
<p>This flag sets the time that the remotes are cached for. If you set
it to <code>0</code> (or negative) then rclone won't cache the remotes
at all.</p>
<p>Note that if you use some flags, eg <code>--backup-dir</code> and if
this is set to <code>0</code> rclone may build two remotes (one for the
source or destination and one for the <code>--backup-dir</code> where it
may have only built one before.</p>
<h3 id="fs-cache-expire-interval-duration">--fs-cache-expire-interval
Duration</h3>
<p>This controls how often rclone checks for cached remotes to expire.
See the <code>--fs-cache-expire-duration</code> documentation above for
more info. The default is 60s, set to 0 to disable expiry.</p>
<h3 id="header-stringarray">--header stringArray</h3>
<p>Add an HTTP header for all transactions. The flag can be repeated to
add multiple headers.</p>
<p>If you want to add headers only for uploads use
<code>--header-upload</code> and if you want to add headers only for
downloads use <code>--header-download</code>.</p>
<p>This flag is supported for all HTTP based backends even those not
supported by <code>--header-upload</code> and
<code>--header-download</code> so may be used as a workaround for those
with care.</p>
<pre class="console"><code>rclone ls remote:test --header &quot;X-Rclone: Foo&quot; --header &quot;X-LetMeIn: Yes&quot;</code></pre>
<h3 id="header-download-stringarray">--header-download stringArray</h3>
<p>Add an HTTP header for all download transactions. The flag can be
repeated to add multiple headers.</p>
<pre class="console"><code>rclone sync --interactive s3:test/src ~/dst --header-download &quot;X-Amz-Meta-Test: Foo&quot; --header-download &quot;X-Amz-Meta-Test2: Bar&quot;</code></pre>
<p>See GitHub issue <a
href="https://github.com/rclone/rclone/issues/59">#59</a> for currently
supported backends.</p>
<h3 id="header-upload-stringarray">--header-upload stringArray</h3>
<p>Add an HTTP header for all upload transactions. The flag can be
repeated to add multiple headers.</p>
<pre class="console"><code>rclone sync --interactive ~/src s3:test/dst --header-upload &quot;Content-Disposition: attachment; filename=&#39;cool.html&#39;&quot; --header-upload &quot;X-Amz-Meta-Test: FooBar&quot;</code></pre>
<p>See GitHub issue <a
href="https://github.com/rclone/rclone/issues/59">#59</a> for currently
supported backends.</p>
<h3 id="http-proxy-string">--http-proxy string</h3>
<p>Use this option to set an HTTP proxy for all HTTP based services to
use.</p>
<p>Rclone also supports the standard HTTP proxy environment variables
which it will pick up automatically. The is the way the HTTP proxy will
normally be set but this flag can be used to override it.</p>
<h3 id="human-readable">--human-readable</h3>
<p>Rclone commands output values for sizes (e.g. number of bytes) and
counts (e.g. number of files) either as <em>raw</em> numbers, or in
<em>human-readable</em> format.</p>
<p>In human-readable format the values are scaled to larger units,
indicated with a suffix shown after the value, and rounded to three
decimals. Rclone consistently uses binary units (powers of 2) for sizes
and decimal units (powers of 10) for counts. The unit prefix for size is
according to IEC standard notation, e.g. <code>Ki</code> for kibi. Used
with byte unit, <code>1 KiB</code> means 1024 Byte. In list type of
output, only the unit prefix appended to the value (e.g.
<code>9.762Ki</code>), while in more textual output the full unit is
shown (e.g. <code>9.762 KiB</code>). For counts the SI standard notation
is used, e.g. prefix <code>k</code> for kilo. Used with file counts,
<code>1k</code> means 1000 files.</p>
<p>The various <a href="https://rclone.org/commands/rclone_ls/">list</a>
commands output raw numbers by default. Option
<code>--human-readable</code> will make them output values in
human-readable format instead (with the short unit prefix).</p>
<p>The <a href="https://rclone.org/commands/rclone_about/">about</a>
command outputs human-readable by default, with a command-specific
option <code>--full</code> to output the raw numbers instead.</p>
<p>Command <a href="https://rclone.org/commands/rclone_size/">size</a>
outputs both human-readable and raw numbers in the same output.</p>
<p>The <a href="https://rclone.org/commands/rclone_tree/">tree</a>
command also considers <code>--human-readable</code>, but it will not
use the exact same notation as the other commands: It rounds to one
decimal, and uses single letter suffix, e.g. <code>K</code> instead of
<code>Ki</code>. The reason for this is that it relies on an external
library.</p>
<p>The interactive command <a
href="https://rclone.org/commands/rclone_ncdu/">ncdu</a> shows
human-readable by default, and responds to key <code>u</code> for
toggling human-readable format.</p>
<h3 id="ignore-case-sync">--ignore-case-sync</h3>
<p>Using this option will cause rclone to ignore the case of the files
when synchronizing so files will not be copied/synced when the existing
filenames are the same, even if the casing is different.</p>
<h3 id="ignore-checksum">--ignore-checksum</h3>
<p>Normally rclone will check that the checksums of transferred files
match, and give an error "corrupted on transfer" if they don't.</p>
<p>You can use this option to skip that check. You should only use it if
you have had the "corrupted on transfer" error message and you are sure
you might want to transfer potentially corrupted data.</p>
<h3 id="ignore-existing">--ignore-existing</h3>
<p>Using this option will make rclone unconditionally skip all files
that exist on the destination, no matter the content of these files.</p>
<p>While this isn't a generally recommended option, it can be useful in
cases where your files change due to encryption. However, it cannot
correct partial transfers in case a transfer was interrupted.</p>
<p>When performing a <code>move</code>/<code>moveto</code> command, this
flag will leave skipped files in the source location unchanged when a
file with the same name exists on the destination.</p>
<h3 id="ignore-size">--ignore-size</h3>
<p>Normally rclone will look at modification time and size of files to
see if they are equal. If you set this flag then rclone will check only
the modification time. If <code>--checksum</code> is set then it only
checks the checksum.</p>
<p>It will also cause rclone to skip verifying the sizes are the same
after transfer.</p>
<p>This can be useful for transferring files to and from OneDrive which
occasionally misreports the size of image files (see <a
href="https://github.com/rclone/rclone/issues/399">#399</a> for more
info).</p>
<h3 id="i---ignore-times">-I, --ignore-times</h3>
<p>Using this option will cause rclone to unconditionally upload all
files regardless of the state of files on the destination.</p>
<p>Normally rclone would skip any files that have the same modification
time and are the same size (or have the same checksum if using
<code>--checksum</code>).</p>
<h3 id="immutable">--immutable</h3>
<p>Treat source and destination files as immutable and disallow
modification.</p>
<p>With this option set, files will be created and deleted as requested,
but existing files will never be updated. If an existing file does not
match between the source and destination, rclone will give the error
<code>Source and destination exist but do not match: immutable file modified</code>.</p>
<p>Note that only commands which transfer files (e.g. <a
href="https://rclone.org/commands/rclone_sync/">sync</a>, <a
href="https://rclone.org/commands/rclone_copy/">copy</a> or <a
href="https://rclone.org/commands/rclone_move/">move</a>) are affected
by this behavior, and only modification is disallowed. Files may still
be deleted explicitly (e.g. <a
href="https://rclone.org/commands/rclone_delete/">delete</a>, <a
href="https://rclone.org/commands/rclone_purge/">purge</a>) or
implicitly (e.g. <a
href="https://rclone.org/commands/rclone_sync/">sync</a>, <a
href="https://rclone.org/commands/rclone_move/">move</a>). Use
<code>copy --immutable</code> if it is desired to avoid deletion as well
as modification.</p>
<p>This can be useful as an additional layer of protection for immutable
or append-only data sets (notably backup archives), where modification
implies corruption and should not be propagated.</p>
<h3 id="inplace">--inplace</h3>
<p>The <code>--inplace</code> flag changes the behaviour of rclone when
uploading files to some backends (backends with the
<code>PartialUploads</code> feature flag set) such as:</p>
<ul>
<li>local</li>
<li>ftp</li>
<li>sftp</li>
<li>pcloud</li>
</ul>
<p>Without <code>--inplace</code> (the default) rclone will first upload
to a temporary file with an extension like this, where
<code>XXXXXX</code> represents a hash of the source file's fingerprint
and <code>.partial</code> is <a
href="#partial-suffix">--partial-suffix</a> value (<code>.partial</code>
by default).</p>
<pre class="text"><code>original-file-name.XXXXXX.partial</code></pre>
<p>(rclone will make sure the final name is no longer than 100
characters by truncating the <code>original-file-name</code> part if
necessary).</p>
<p>When the upload is complete, rclone will rename the
<code>.partial</code> file to the correct name, overwriting any existing
file at that point. If the upload fails then the <code>.partial</code>
file will be deleted.</p>
<p>This prevents other users of the backend from seeing partially
uploaded files in their new names and prevents overwriting the old file
until the new one is completely uploaded.</p>
<p>If the <code>--inplace</code> flag is supplied, rclone will upload
directly to the final name without creating a <code>.partial</code>
file.</p>
<p>This means that an incomplete file will be visible in the directory
listings while the upload is in progress and any existing files will be
overwritten as soon as the upload starts. If the transfer fails then the
file will be deleted. This can cause data loss of the existing file if
the transfer fails.</p>
<p>Note that on the local file system if you don't use
<code>--inplace</code> hard links (Unix only) will be broken. And if you
do use <code>--inplace</code> you won't be able to update in use
executables.</p>
<p>Note also that versions of rclone prior to v1.63.0 behave as if the
<code>--inplace</code> flag is always supplied.</p>
<h3 id="interactive">-i, --interactive</h3>
<p>This flag can be used to tell rclone that you wish a manual
confirmation before destructive operations.</p>
<p>It is <strong>recommended</strong> that you use this flag while
learning rclone especially with <code>rclone sync</code>.</p>
<p>For example</p>
<pre class="console"><code>$ rclone delete --interactive /tmp/dir
rclone: delete &quot;important-file.txt&quot;?
y) Yes, this is OK (default)
n) No, skip this
s) Skip all delete operations with no more questions
!) Do all delete operations with no more questions
q) Exit rclone now.
y/n/s/!/q&gt; n</code></pre>
<p>The options mean</p>
<ul>
<li><code>y</code>: <strong>Yes</strong>, this operation should go
ahead. You can also press Return for this to happen. You'll be asked
every time unless you choose <code>s</code> or <code>!</code>.</li>
<li><code>n</code>: <strong>No</strong>, do not do this operation.
You'll be asked every time unless you choose <code>s</code> or
<code>!</code>.</li>
<li><code>s</code>: <strong>Skip</strong> all the following operations
of this type with no more questions. This takes effect until rclone
exits. If there are any different kind of operations you'll be prompted
for them.</li>
<li><code>!</code>: <strong>Do all</strong> the following operations
with no more questions. Useful if you've decided that you don't mind
rclone doing that kind of operation. This takes effect until rclone
exits . If there are any different kind of operations you'll be prompted
for them.</li>
<li><code>q</code>: <strong>Quit</strong> rclone now, just in case!</li>
</ul>
<h3 id="leave-root">--leave-root</h3>
<p>During rmdirs it will not remove root directory, even if it's
empty.</p>
<h3 id="l---links">-l, --links</h3>
<p>Normally rclone will ignore symlinks or junction points (which behave
like symlinks under Windows). Ignored files won't be copied, moved or
deleted in a sync.</p>
<p>If you supply this flag then rclone will copy symbolic links from any
supported backend backend, and store them as text files, with a
<code>.rclonelink</code> suffix in the destination.</p>
<p>The text file will contain the target of the symbolic link.</p>
<p>The <code>--links</code> / <code>-l</code> flag enables this feature
for all supported backends and the VFS. There are individual flags for
just enabling it for the VFS <code>--vfs-links</code> and the local
backend <code>--local-links</code> if required.</p>
<h3 id="list-cutoff">--list-cutoff int</h3>
<p>When syncing rclone needs to sort directory entries before comparing
them. Below this threshold (1,000,000) by default, rclone will store the
directory entries in memory. 1,000,000 entries will take approx 1GB of
RAM to store. Above this threshold rclone will store directory entries
on disk and sort them without using a lot of memory.</p>
<p>Doing this is slightly less efficient then sorting them in memory and
will only work well for the bucket based backends (eg s3, b2, azureblob,
swift) but these are the only backends likely to have millions of
entries in a directory.</p>
<h3 id="log-file-string">--log-file string</h3>
<p>Log all of rclone's output to a file. This is not active by default.
This can be useful for tracking down problems with syncs in combination
with the <code>-v</code> flag. See the <a href="#logging">logging</a>
section for more info.</p>
<p>If the file exists, then rclone will append to it.</p>
<p>Note that if you are using the <code>logrotate</code> program to
manage rclone's logs, then you should use the <code>copytruncate</code>
option as rclone doesn't have a signal to rotate logs.</p>
<p>Alternatively you can use the options below to manage rclone's built
in log rotation.</p>
<h3 id="log-file-max-size-sizesuffix">--log-file-max-size
SizeSuffix</h3>
<p>Maximum size of the log file before it's rotated (eg
<code>10M</code>). This SizeSuffix is rounded to the nearest MiB or 1
MiB if lower.</p>
<p>If <code>--log-file</code> is not set then this option will be
ignored.</p>
<p>If this option is not set, then the other log rotation options will
be ignored.</p>
<p>For example if the following flags are in use</p>
<pre class="console"><code>rclone --log-file rclone.log --log-file-max-size 1M --log-file-max-backups 3</code></pre>
<p>Then this will create log files which look like this</p>
<pre class="console"><code>$ ls -l
-rw-------  1 user user  1048491 Apr 11 17:15 rclone-2025-04-11T17-15-29.998.log
-rw-------  1 user user  1048511 Apr 11 17:15 rclone-2025-04-11T17-15-30.467.log
-rw-------  1 user user  1048559 Apr 11 17:15 rclone-2025-04-11T17-15-30.543.log
-rw-------  1 user user   521602 Apr 11 17:15 rclone.log</code></pre>
<p>The file <code>rclone.log</code> being the current one.</p>
<h3 id="log-file-compress">--log-file-compress</h3>
<p>If set, compress rotated log files using gzip. This changes the
extension of the old log files to <code>.log.gz</code>.</p>
<p>Defaults to false - don't compress log files.</p>
<h3 id="log-file-max-age-duration">--log-file-max-age Duration</h3>
<p>Maximum duration to retain old log files (eg <code>7d</code>). This
is rounded to the dearest day, or 1 day if lower.</p>
<p>The default is to retain all old log files.</p>
<h3 id="log-file-max-backups-int">--log-file-max-backups int</h3>
<p>Maximum number of old log files to retain</p>
<p>The default is to retain all old log files.</p>
<h3 id="log-format-string">--log-format string</h3>
<p>Comma separated list of log format options. The accepted options
are:</p>
<ul>
<li><code>date</code> - Add a date in the format YYYY/MM/YY to the
log.</li>
<li><code>time</code> - Add a time to the log in format HH:MM:SS.</li>
<li><code>microseconds</code> - Add microseconds to the time in format
HH:MM:SS.SSSSSS.</li>
<li><code>UTC</code> - Make the logs in UTC not localtime.</li>
<li><code>longfile</code> - Adds the source file and line number of the
log statement.</li>
<li><code>shortfile</code> - Adds the source file and line number of the
log statement.</li>
<li><code>pid</code> - Add the process ID to the log - useful with
<code>rclone mount --daemon</code>.</li>
<li><code>nolevel</code> - Don't add the level to the log.</li>
<li><code>json</code> - Equivalent to adding
<code>--use-json-log</code></li>
</ul>
<p>They are added to the log line in the order above.</p>
<p>The default log format is <code>"date,time"</code>.</p>
<h3 id="log-level-loglevel">--log-level LogLevel</h3>
<p>This sets the log level for rclone. The default log level is
<code>NOTICE</code>.</p>
<p><code>DEBUG</code> is equivalent to <code>-vv</code>. It outputs lots
of debug info - useful for bug reports and really finding out what
rclone is doing.</p>
<p><code>INFO</code> is equivalent to <code>-v</code>. It outputs
information about each transfer and prints stats once a minute by
default.</p>
<p><code>NOTICE</code> is the default log level if no logging flags are
supplied. It outputs very little when things are working normally. It
outputs warnings and significant events.</p>
<p><code>ERROR</code> is equivalent to <code>-q</code>. It only outputs
error messages.</p>
<p>See also the <a href="#logging">logging</a> section.</p>
<h3 id="windows-event-log-loglevel">--windows-event-log LogLevel</h3>
<p>If this is configured (the default is <code>OFF</code>) then logs of
this level and above will be logged to the Windows event log in
<strong>addition</strong> to the normal logs. These will be logged in
JSON format as described below regardless of what format the main logs
are configured for.</p>
<p>The Windows event log only has 3 levels of severity
<code>Info</code>, <code>Warning</code> and <code>Error</code>. If
enabled we map rclone levels like this.</p>
<ul>
<li><code>Error</code> ← <code>ERROR</code> (and above)</li>
<li><code>Warning</code> ← <code>WARNING</code> (note that this level is
defined but not currently used).</li>
<li><code>Info</code> ← <code>NOTICE</code>, <code>INFO</code> and
<code>DEBUG</code>.</li>
</ul>
<p>Rclone will declare its log source as "rclone" if it is has enough
permissions to create the registry key needed. If not then logs will
appear as "Application". You can run
<code>rclone version --windows-event-log DEBUG</code> once as
administrator to create the registry key in advance.</p>
<p><strong>Note</strong> that the <code>--windows-event-log</code> level
must be greater (more severe) than or equal to the
<code>--log-level</code>. For example to log DEBUG to a log file but
ERRORs to the event log you would use</p>
<pre class="text"><code>--log-file rclone.log --log-level DEBUG --windows-event-log ERROR</code></pre>
<p>This option is only supported Windows platforms.</p>
<h3 id="use-json-log">--use-json-log</h3>
<p>This switches the log format to JSON. The log messages are then
streamed as individual JSON objects, with fields: <code>level</code>,
<code>msg</code>, <code>source</code>, and <code>time</code>. The
resulting format is what is sometimes referred to as <a
href="https://en.wikipedia.org/wiki/JSON_streaming#Newline-delimited_JSON">newline-delimited
JSON</a> (NDJSON), or JSON Lines (JSONL). This is well suited for
processing by traditional line-oriented tools and shell pipelines, but a
complete log file is not strictly valid JSON and needs a parser that can
handle it.</p>
<p>The JSON logs will be printed on a single line, but are shown
expanded here for clarity.</p>

<h3 id="low-level-retries-int">--low-level-retries int</h3>
<p>This controls the number of low level retries rclone does.</p>
<p>A low level retry is used to retry a failing operation - typically
one HTTP request. This might be uploading a chunk of a big file for
example. You will see low level retries in the log with the
<code>-v</code> flag.</p>
<p>This shouldn't need to be changed from the default in normal
operations. However, if you get a lot of low level retries you may wish
to reduce the value so rclone moves on to a high level retry (see the
<code>--retries</code> flag) quicker.</p>
<p>Disable low level retries with
<code>--low-level-retries 1</code>.</p>
<h3 id="max-backlog-int">--max-backlog int</h3>
<p>This is the maximum allowable backlog of files in a sync/copy/move
queued for being checked or transferred.</p>
<p>This can be set arbitrarily large. It will only use memory when the
queue is in use. Note that it will use in the order of N KiB of memory
when the backlog is in use.</p>
<p>Setting this large allows rclone to calculate how many files are
pending more accurately, give a more accurate estimated finish time and
make <code>--order-by</code> work more accurately.</p>
<p>Setting this small will make rclone more synchronous to the listings
of the remote which may be desirable.</p>
<p>Setting this to a negative number will make the backlog as large as
possible.</p>
<h3 id="max-buffer-memory">--max-buffer-memory SizeSuffix</h3>
<p>If set, don't allocate more than given amount of memory as buffers.
If not set or set to <code>0</code> or <code>off</code> this will not
limit the amount of memory in use.</p>
<p>This includes memory used by buffers created by the
<code>--buffer</code> flag and buffers used by multi-thread
transfers.</p>
<p>Most multi-thread transfers do not take additional memory, but some
do depending on the backend (eg the s3 backend for uploads). This means
there is a tension between total setting <code>--transfers</code> as
high as possible and memory use.</p>
<p>Setting <code>--max-buffer-memory</code> allows the buffer memory to
be controlled so that it doesn't overwhelm the machine and allows
<code>--transfers</code> to be set large.</p>
<h3 id="max-connections-int">--max-connections int</h3>
<p>This sets the maximum number of concurrent calls to the backend API.
It may not map 1:1 to TCP or HTTP connections depending on the backend
in use and the use of HTTP1 vs HTTP2.</p>
<p>When downloading files, backends only limit the initial opening of
the stream. The bulk data download is not counted as a connection. This
means that the <code>--max--connections</code> flag won't limit the
total number of downloads.</p>
<p>Note that it is possible to cause deadlocks with this setting so it
should be used with care.</p>
<p>If you are doing a sync or copy then make sure
<code>--max-connections</code> is one more than the sum of
<code>--transfers</code> and <code>--checkers</code>.</p>
<p>If you use <code>--check-first</code> then
<code>--max-connections</code> just needs to be one more than the
maximum of <code>--checkers</code> and <code>--transfers</code>.</p>
<p>So for <code>--max-connections 3</code> you'd use
<code>--checkers 2 --transfers 2 --check-first</code> or
<code>--checkers 1 --transfers 1</code>.</p>
<p>Setting this flag can be useful for backends which do multipart
uploads to limit the number of simultaneous parts being transferred.</p>
<h3 id="max-delete-int">--max-delete int</h3>
<p>This tells rclone not to delete more than N files. If that limit is
exceeded then a fatal error will be generated and rclone will stop the
operation in progress.</p>
<h3 id="max-delete-size-sizesuffix">--max-delete-size SizeSuffix</h3>
<p>Rclone will stop deleting files when the total size of deletions has
reached the size specified. It defaults to off.</p>
<p>If that limit is exceeded then a fatal error will be generated and
rclone will stop the operation in progress.</p>
<h3 id="max-depth-int">--max-depth int</h3>
<p>This modifies the recursion depth for all the commands except
purge.</p>
<p>So if you do <code>rclone --max-depth 1 ls remote:path</code> you
will see only the files in the top level directory. Using
<code>--max-depth 2</code> means you will see all the files in first two
directory levels and so on.</p>
<p>For historical reasons the <code>lsd</code> command defaults to using
a <code>--max-depth</code> of 1 - you can override this with the command
line flag.</p>
<p>You can use this command to disable recursion (with
<code>--max-depth 1</code>).</p>
<p>Note that if you use this with <code>sync</code> and
<code>--delete-excluded</code> the files not recursed through are
considered excluded and will be deleted on the destination. Test first
with <code>--dry-run</code> if you are not sure what will happen.</p>
<h3 id="max-duration-duration">--max-duration Duration</h3>
<p>Rclone will stop transferring when it has run for the duration
specified. Defaults to off.</p>
<p>When the limit is reached all transfers will stop immediately. Use
<code>--cutoff-mode</code> to modify this behaviour.</p>
<p>Rclone will exit with exit code 10 if the duration limit is
reached.</p>
<h3 id="max-transfer-sizesuffix">--max-transfer SizeSuffix</h3>
<p>Rclone will stop transferring when it has reached the size specified.
Defaults to off.</p>
<p>When the limit is reached all transfers will stop immediately. Use
<code>--cutoff-mode</code> to modify this behaviour.</p>
<p>Rclone will exit with exit code 8 if the transfer limit is
reached.</p>
<h3 id="cutoff-mode-hardsoftcautious">--cutoff-mode
HARD|SOFT|CAUTIOUS</h3>
<p>Configure the behavior of <code>--max-transfer</code> and
<code>--max-duration</code>.</p>
<p><code>HARD</code> will stop transferring immediately when rclone
reaches the limit. This is the default.</p>
<p><code>SOFT</code> will stop starting new transfers when rclone
reaches the limit.</p>
<p><code>CAUTIOUS</code> will try to prevent rclone from reaching the
limit. Only applicable for <code>--max-transfer</code>.</p>
<h2 id="m---metadata">-M, --metadata</h2>
<p>Setting this flag enables rclone to copy the metadata from the source
to the destination. For local backends this is ownership, permissions,
xattr etc. See the <a href="#metadata">metadata section</a> for more
info.</p>
<h3 id="metadata-mapper">--metadata-mapper SpaceSepList</h3>
<p>If you supply the parameter
<code>--metadata-mapper /path/to/program</code> then rclone will use
that program to map metadata from source object to destination
object.</p>
<p>The argument to this flag should be a command with an optional space
separated list of arguments. If one of the arguments has a space in then
enclose it in <code>"</code>, if you want a literal <code>"</code> in an
argument then enclose the argument in <code>"</code> and double the
<code>"</code>. See <a href="https://godoc.org/encoding/csv">CSV
encoding</a> for more info.</p>
<pre class="text"><code>--metadata-mapper &quot;python bin/test_metadata_mapper.py&quot;
--metadata-mapper &#39;python bin/test_metadata_mapper.py &quot;argument with a space&quot;&#39;
--metadata-mapper &#39;python bin/test_metadata_mapper.py &quot;argument with &quot;&quot;two&quot;&quot; quotes&quot;&#39;</code></pre>
<p>This uses a simple JSON based protocol with input on STDIN and output
on STDOUT. This will be called for every file and directory copied and
may be called concurrently.</p>
<p>The program's job is to take a metadata blob on the input and turn it
into a metadata blob on the output suitable for the destination
backend.</p>
<p>Input to the program (via STDIN) might look like this. This provides
some context for the <code>Metadata</code> which may be important.</p>
<ul>
<li><code>SrcFs</code> is the config string for the remote that the
object is currently on.</li>
<li><code>SrcFsType</code> is the name of the source backend.</li>
<li><code>DstFs</code> is the config string for the remote that the
object is being copied to</li>
<li><code>DstFsType</code> is the name of the destination backend.</li>
<li><code>Remote</code> is the path of the object relative to the
root.</li>
<li><code>Size</code>, <code>MimeType</code>, <code>ModTime</code> are
attributes of the object.</li>
<li><code>IsDir</code> is <code>true</code> if this is a directory (not
yet implemented).</li>
<li><code>ID</code> is the source <code>ID</code> of the object if
known.</li>
<li><code>Metadata</code> is the backend specific metadata as described
in the backend docs.</li>

<p>You can find this example (slightly expanded) in the rclone source
code at <a
href="https://github.com/rclone/rclone/blob/master/bin/test_metadata_mapper.py">bin/test_metadata_mapper.py</a>.</p>
<p>If you want to see the input to the metadata mapper and the output
returned from it in the log you can use
<code>-vv --dump mapper</code>.</p>
<p>See the <a href="#metadata">metadata section</a> for more info.</p>
<h3 id="metadata-set-stringarray">--metadata-set stringArray</h3>
<p>Specify value as string in format <code>key=value</code> to add
metadata <code>key</code> with value <code>value</code> when uploading.
This can be repeated as many times as required. See the <a
href="#metadata">metadata section</a> for more info.</p>
<h3 id="modify-window-duration">--modify-window Duration</h3>
<p>When checking whether a file has been modified, this is the maximum
allowed time difference that a file can have and still be considered
equivalent.</p>
<p>The default is <code>1ns</code> unless this is overridden by a
remote. For example OS X only stores modification times to the nearest
second so if you are reading and writing to an OS X filing system this
will be <code>1s</code> by default.</p>
<p>This command line flag allows you to override that computed
default.</p>
<h3
id="multi-thread-write-buffer-size-sizesuffix">--multi-thread-write-buffer-size
SizeSuffix</h3>
<p>When transferring with multiple threads, rclone will buffer the
specified number of bytes in memory before writing to disk for each
thread.</p>
<p>This can improve performance if the underlying filesystem does not
deal well with a lot of small writes in different positions of the file,
so if you see transfers being limited by disk write speed, you might
want to experiment with different values. Specially for magnetic drives
and remote file systems a higher value can be useful.</p>
<p>Nevertheless, the default of <code>128k</code> should be fine for
almost all use cases, so before changing it ensure that network is not
really your bottleneck.</p>
<p>As a final hint, size is not the only factor: block size (or similar
concept) can have an impact. In one case, we observed that exact
multiples of 16k performed much better than other values.</p>
<h3 id="multi-thread-chunk-size-sizesuffix">--multi-thread-chunk-size
SizeSuffix</h3>
<p>Normally the chunk size for multi thread transfers is set by the
backend. However some backends such as <code>local</code> and
<code>smb</code> (which implement <code>OpenWriterAt</code> but not
<code>OpenChunkWriter</code>) don't have a natural chunk size.</p>
<p>In this case the value of this option is used (default 64Mi).</p>
<h3 id="multi-thread-cutoff">--multi-thread-cutoff SizeSuffix</h3>
<p>When transferring files above specified size to capable backends,
rclone will use multiple threads to transfer the file (default
256M).</p>
<p>Capable backends are marked in the <a
href="https://rclone.org/overview/#optional-features">overview</a> as
<code>MultithreadUpload</code>. (They need to implement either the
<code>OpenWriterAt</code> or <code>OpenChunkWriter</code> internal
interfaces). These include include, <code>local</code>, <code>s3</code>,
<code>azureblob</code>, <code>b2</code>,
<code>oracleobjectstorage</code> and <code>smb</code> at the time of
writing.</p>
<p>On the local disk, rclone preallocates the file (using
<code>fallocate(FALLOC_FL_KEEP_SIZE)</code> on unix or
<code>NTSetInformationFile</code> on Windows both of which takes no
time) then each thread writes directly into the file at the correct
place. This means that rclone won't create fragmented or sparse files
and there won't be any assembly time at the end of the transfer.</p>
<p>The number of threads used to transfer is controlled by
<code>--multi-thread-streams</code>.</p>
<p>Use <code>-vv</code> if you wish to see info about the threads.</p>
<p>This will work with the <a
href="https://rclone.org/commands/rclone_sync/">sync</a>, <a
href="https://rclone.org/commands/rclone_copy/">copy</a> and <a
href="https://rclone.org/commands/rclone_move/">move</a> commands, and
friends <a href="https://rclone.org/commands/rclone_copyto/">copyto</a>,
<a href="https://rclone.org/commands/rclone_moveto/">moveto</a>. Multi
thread transfers will be used with <code>rclone mount</code> and
<code>rclone serve</code> if <code>--vfs-cache-mode</code> is set to
<code>writes</code> or above.</p>
<p>Most multi-thread transfers do not take additional memory, but some
do (for example uploading to s3). In the worst case memory usage can be
at maximum <code>--transfers</code> *
<code>--multi-thread-chunk-size</code> *
<code>--multi-thread-streams</code> or specifically for the s3 backend
<code>--transfers</code> * <code>--s3-chunk-size</code> *
<code>--s3-concurrency</code>. However you can use the the <a
href="https://rclone.org/docs/#max-buffer-memory">--max-buffer-memory</a>
flag to control the maximum memory used here.</p>
<p><strong>NB</strong> that this <strong>only</strong> works with
supported backends as the destination but will work with any backend as
the source.</p>
<p><strong>NB</strong> that multi-thread copies are disabled for local
to local copies as they are faster without unless
<code>--multi-thread-streams</code> is set explicitly.</p>
<p><strong>NB</strong> on Windows using multi-thread transfers to the
local disk will cause the resulting files to be <a
href="https://en.wikipedia.org/wiki/Sparse_file">sparse</a>. Use
<code>--local-no-sparse</code> to disable sparse files (which may cause
long delays at the start of transfers) or disable multi-thread transfers
with <code>--multi-thread-streams 0</code></p>
<h3 id="multi-thread-streams-int">--multi-thread-streams int</h3>
<p>When using multi thread transfers (see above
<code>--multi-thread-cutoff</code>) this sets the number of streams to
use. Set to <code>0</code> to disable multi thread transfers (Default
4).</p>
<p>If the backend has a <code>--backend-upload-concurrency</code>
setting (eg <code>--s3-upload-concurrency</code>) then this setting will
be used as the number of transfers instead if it is larger than the
value of <code>--multi-thread-streams</code> or
<code>--multi-thread-streams</code> isn't set.</p>
<h3 id="name-transform-stringarray">--name-transform stringArray</h3>
<p><code>--name-transform</code> introduces path name transformations
for <code>rclone copy</code>, <code>rclone sync</code>, and
<code>rclone move</code>. These transformations enable modifications to
source and destination file names by applying prefixes, suffixes, and
other alterations during transfer operations. For detailed docs and
examples, see <a
href="https://rclone.org/commands/rclone_convmv/"><code>convmv</code></a>.</p>
<h3 id="no-check-dest">--no-check-dest</h3>
<p>The <code>--no-check-dest</code> can be used with <code>move</code>
or <code>copy</code> and it causes rclone not to check the destination
at all when copying files.</p>
<p>This means that:</p>
<ul>
<li>the destination is not listed minimising the API calls</li>
<li>files are always transferred</li>
<li>this can cause duplicates on remotes which allow it (e.g. Google
Drive)</li>
<li><code>--retries 1</code> is recommended otherwise you'll transfer
everything again on a retry</li>
</ul>
<p>This flag is useful to minimise the transactions if you know that
none of the files are on the destination.</p>
<p>This is a specialized flag which should be ignored by most users!</p>
<h3 id="no-gzip-encoding">--no-gzip-encoding</h3>
<p>Don't set <code>Accept-Encoding: gzip</code>. This means that rclone
won't ask the server for compressed files automatically. Useful if
you've set the server to return files with
<code>Content-Encoding: gzip</code> but you uploaded compressed
files.</p>
<p>There is no need to set this in normal operation, and doing so will
decrease the network transfer efficiency of rclone.</p>
<h3 id="no-traverse">--no-traverse</h3>
<p>The <code>--no-traverse</code> flag controls whether the destination
file system is traversed when using the <code>copy</code> or
<code>move</code> commands. <code>--no-traverse</code> is not compatible
with <code>sync</code> and will be ignored if you supply it with
<code>sync</code>.</p>
<p>If you are only copying a small number of files (or are filtering
most of the files) and/or have a large number of files on the
destination then <code>--no-traverse</code> will stop rclone listing the
destination and save time.</p>
<p>However, if you are copying a large number of files, especially if
you are doing a copy where lots of the files under consideration haven't
changed and won't need copying then you shouldn't use
<code>--no-traverse</code>.</p>
<p>See <a href="https://rclone.org/commands/rclone_copy/">rclone
copy</a> for an example of how to use it.</p>
<h3 id="no-unicode-normalization">--no-unicode-normalization</h3>
<p>Don't normalize unicode characters in filenames during the sync
routine.</p>
<p>Sometimes, an operating system will store filenames containing
unicode parts in their decomposed form (particularly macOS). Some cloud
storage systems will then recompose the unicode, resulting in duplicate
files if the data is ever copied back to a local filesystem.</p>
<p>Using this flag will disable that functionality, treating each
unicode character as unique. For example, by default é and é will be
normalized into the same character. With
<code>--no-unicode-normalization</code> they will be treated as unique
characters.</p>
<h3 id="no-update-modtime">--no-update-modtime</h3>
<p>When using this flag, rclone won't update modification times of
remote files if they are incorrect as it would normally.</p>
<p>This can be used if the remote is being synced with another tool also
(e.g. the Google Drive client).</p>
<h3 id="no-update-dir-modtime">--no-update-dir-modtime</h3>
<p>When using this flag, rclone won't update modification times of
remote directories if they are incorrect as it would normally.</p>
<h3 id="order-by-string">--order-by string</h3>
<p>The <code>--order-by</code> flag controls the order in which files in
the backlog are processed in <code>rclone sync</code>,
<code>rclone copy</code> and <code>rclone move</code>.</p>
<p>The order by string is constructed like this. The first part
describes what aspect is being measured:</p>
<ul>
<li><code>size</code> - order by the size of the files</li>
<li><code>name</code> - order by the full path of the files</li>
<li><code>modtime</code> - order by the modification date of the
files</li>
</ul>
<p>This can have a modifier appended with a comma:</p>
<ul>
<li><code>ascending</code> or <code>asc</code> - order so that the
smallest (or oldest) is processed first</li>
<li><code>descending</code> or <code>desc</code> - order so that the
largest (or newest) is processed first</li>
<li><code>mixed</code> - order so that the smallest is processed first
for some threads and the largest for others</li>
</ul>
<p>If the modifier is <code>mixed</code> then it can have an optional
percentage (which defaults to <code>50</code>), e.g.
<code>size,mixed,25</code> which means that 25% of the threads should be
taking the smallest items and 75% the largest. The threads which take
the smallest first will always take the smallest first and likewise the
largest first threads. The <code>mixed</code> mode can be useful to
minimise the transfer time when you are transferring a mixture of large
and small files - the large files are guaranteed upload threads and
bandwidth and the small files will be processed continuously.</p>
<p>If no modifier is supplied then the order is
<code>ascending</code>.</p>
<p>For example</p>
<ul>
<li><code>--order-by size,desc</code> - send the largest files
first</li>
<li><code>--order-by modtime,ascending</code> - send the oldest files
first</li>
<li><code>--order-by name</code> - send the files with alphabetically by
path first</li>
</ul>
<p>If the <code>--order-by</code> flag is not supplied or it is supplied
with an empty string then the default ordering will be used which is as
scanned. With <code>--checkers 1</code> this is mostly alphabetical,
however with the default <code>--checkers 8</code> it is somewhat
random.</p>
<h4 id="limitations-3">Limitations</h4>
<p>The <code>--order-by</code> flag does not do a separate pass over the
data. This means that it may transfer some files out of the order
specified if</p>
<ul>
<li>there are no files in the backlog or the source has not been fully
scanned yet</li>
<li>there are more than <a href="#max-backlog-int">--max-backlog</a>
files in the backlog</li>
</ul>
<p>Rclone will do its best to transfer the best file it has so in
practice this should not cause a problem. Think of
<code>--order-by</code> as being more of a best efforts flag rather than
a perfect ordering.</p>
<p>If you want perfect ordering then you will need to specify <a
href="#check-first">--check-first</a> which will find all the files
which need transferring first before transferring any.</p>
<h3 id="partial-suffix">--partial-suffix string</h3>
<p>When <a href="#inplace">--inplace</a> is not used, it causes rclone
to use the <code>--partial-suffix</code> as suffix for temporary
files.</p>
<p>Suffix length limit is 16 characters.</p>
<p>The default is <code>.partial</code>.</p>
<h3 id="password-command">--password-command SpaceSepList</h3>
<p>This flag supplies a program which should supply the config password
when run. This is an alternative to rclone prompting for the password or
setting the <code>RCLONE_CONFIG_PASS</code> variable. It is also used
when setting the config password for the first time.</p>
<p>The argument to this should be a command with a space separated list
of arguments. If one of the arguments has a space in then enclose it in
<code>"</code>, if you want a literal <code>"</code> in an argument then
enclose the argument in <code>"</code> and double the <code>"</code>.
See <a href="https://godoc.org/encoding/csv">CSV encoding</a> for more
info.</p>
<p>Eg</p>
<pre class="text"><code>--password-command &quot;echo hello&quot;
--password-command &#39;echo &quot;hello with space&quot;&#39;
--password-command &#39;echo &quot;hello with &quot;&quot;quotes&quot;&quot; and space&quot;&#39;</code></pre>
<p>Note that when changing the configuration password the environment
variable <code>RCLONE_PASSWORD_CHANGE=1</code> will be set. This can be
used to distinguish initial decryption of the config file from the new
password.</p>
<p>See the <a href="#configuration-encryption">Configuration
Encryption</a> for more info.</p>
<p>See a <a
href="https://github.com/rclone/rclone/wiki/Windows-Powershell-use-rclone-password-command-for-Config-file-password">Windows
PowerShell example on the Wiki</a>.</p>
<h3 id="p---progress">-P, --progress</h3>
<p>This flag makes rclone update the stats in a static block in the
terminal providing a realtime overview of the transfer.</p>
<p>Any log messages will scroll above the static block. Log messages
will push the static block down to the bottom of the terminal where it
will stay.</p>
<p>Normally this is updated every 500mS but this period can be
overridden with the <code>--stats</code> flag.</p>
<p>This can be used with the <code>--stats-one-line</code> flag for a
simpler display.</p>
<p>To change the display length of filenames (for different terminal
widths), see the <code>--stats-file-name-length</code> option. The
default output is formatted for 80 character wide terminals.</p>
<p>Note: On Windows until <a
href="https://github.com/Azure/go-ansiterm/issues/26">this bug</a> is
fixed all non-ASCII characters will be replaced with <code>.</code> when
<code>--progress</code> is in use.</p>
<h3 id="progress-terminal-title">--progress-terminal-title</h3>
<p>This flag, when used with <code>-P/--progress</code>, will print the
string <code>ETA: %s</code> to the terminal title.</p>
<h3 id="q---quiet">-q, --quiet</h3>
<p>This flag will limit rclone's output to error messages only.</p>
<h3 id="refresh-times">--refresh-times</h3>
<p>The <code>--refresh-times</code> flag can be used to update
modification times of existing files when they are out of sync on
backends which don't support hashes.</p>
<p>This is useful if you uploaded files with the incorrect timestamps
and you now wish to correct them.</p>
<p>This flag is <strong>only</strong> useful for destinations which
don't support hashes (e.g. <code>crypt</code>).</p>
<p>This can be used any of the sync commands <a
href="https://rclone.org/commands/rclone_sync/">sync</a>, <a
href="https://rclone.org/commands/rclone_copy/">copy</a> or <a
href="https://rclone.org/commands/rclone_move/">move</a>.</p>
<p>To use this flag you will need to be doing a modification time sync
(so not using <code>--size-only</code> or <code>--checksum</code>). The
flag will have no effect when using <code>--size-only</code> or
<code>--checksum</code>.</p>
<p>If this flag is used when rclone comes to upload a file it will check
to see if there is an existing file on the destination. If this file
matches the source with size (and checksum if available) but has a
differing timestamp then instead of re-uploading it, rclone will update
the timestamp on the destination file. If the checksum does not match
rclone will upload the new file. If the checksum is absent (e.g. on a
<code>crypt</code> backend) then rclone will update the timestamp.</p>
<p>Note that some remotes can't set the modification time without
re-uploading the file so this flag is less useful on them.</p>
<p>Normally if you are doing a modification time sync rclone will update
modification times without <code>--refresh-times</code> provided that
the remote supports checksums <strong>and</strong> the checksums match
on the file. However if the checksums are absent then rclone will upload
the file rather than setting the timestamp as this is the safe
behaviour.</p>
<h3 id="retries-int">--retries int</h3>
<p>Retry the entire sync if it fails this many times it fails (default
3).</p>
<p>Some remotes can be unreliable and a few retries help pick up the
files which didn't get transferred because of errors.</p>
<p>Disable retries with <code>--retries 1</code>.</p>
<h3 id="retries-sleep-duration">--retries-sleep Duration</h3>
<p>This sets the interval between each retry specified by
<code>--retries</code></p>
<p>The default is <code>0</code>. Use <code>0</code> to disable.</p>
<h3 id="server-side-across-configs">--server-side-across-configs</h3>
<p>Allow server-side operations (e.g. copy or move) to work across
different configurations.</p>
<p>This can be useful if you wish to do a server-side copy or move
between two remotes which use the same backend but are configured
differently.</p>
<p>Note that this isn't enabled by default because it isn't easy for
rclone to tell if it will work between any two configurations.</p>
<h3 id="size-only">--size-only</h3>
<p>Normally rclone will look at modification time and size of files to
see if they are equal. If you set this flag then rclone will check only
the size.</p>
<p>This can be useful transferring files from Dropbox which have been
modified by the desktop sync client which doesn't set checksums of
modification times in the same way as rclone.</p>
<h3 id="stats-duration">--stats Duration</h3>
<p>Commands which transfer data (<a
href="https://rclone.org/commands/rclone_sync/">sync</a>, <a
href="https://rclone.org/commands/rclone_copy/">copy</a>, <a
href="https://rclone.org/commands/rclone_copyto/">copyto</a>, <a
href="https://rclone.org/commands/rclone_move/">move</a>, <a
href="https://rclone.org/commands/rclone_moveto/">moveto</a>) will print
data transfer stats at regular intervals to show their progress.</p>
<p>This sets the interval.</p>
<p>The default is <code>1m</code>. Use <code>0</code> to disable.</p>
<p>If you set the stats interval then all commands can show stats. This
can be useful when running other commands, <code>check</code> or
<code>mount</code> for example.</p>
<p>Stats are logged at <code>INFO</code> level by default which means
they won't show at default log level <code>NOTICE</code>. Use
<code>--stats-log-level NOTICE</code> or <code>-v</code> to make them
show. See the <a href="#logging">logging</a> section for more info on
log levels.</p>
<p>Note that on macOS you can send a SIGINFO (which is normally ctrl-T
in the terminal) to make the stats print immediately.</p>
<h3 id="stats-file-name-length-int">--stats-file-name-length int</h3>
<p>By default, the <code>--stats</code> output will truncate file names
and paths longer than 40 characters. This is equivalent to providing
<code>--stats-file-name-length 40</code>. Use
<code>--stats-file-name-length 0</code> to disable any truncation of
file names printed by stats.</p>
<h3 id="stats-log-level-loglevel">--stats-log-level LogLevel</h3>
<p>Log level to show <code>--stats</code> output at. This can be
<code>DEBUG</code>, <code>INFO</code>, <code>NOTICE</code>, or
<code>ERROR</code>. The default is <code>INFO</code>. This means at the
default level of logging, which is <code>NOTICE</code>, the stats won't
show - if you want them to then use
<code>--stats-log-level NOTICE</code>. See the <a
href="#logging">logging</a> section for more details on log levels.</p>
<h3 id="stats-one-line">--stats-one-line</h3>
<p>When this is specified, rclone condenses the stats into a single line
showing the most important stats only.</p>
<h3 id="stats-one-line-date">--stats-one-line-date</h3>
<p>When this is specified, rclone enables the single-line stats and
prepends <!-- markdownlint-disable-next-line no-space-in-code --> the
display with a date string. The default is
<code>2006/01/02 15:04:05 -</code></p>
<h3 id="stats-one-line-date-format-string">--stats-one-line-date-format
string</h3>
<p>When this is specified, rclone enables the single-line stats and
prepends the display with a user-supplied date string. The date string
MUST be enclosed in quotes. Follow <a
href="https://golang.org/pkg/time/#Time.Format">golang specs</a> for
date formatting syntax.</p>
<h3 id="stats-unit-string">--stats-unit string</h3>
<p>By default, data transfer rates will be printed in bytes per second,
corresponding to <code>--stats-unit bytes</code>.</p>
<p>This option allows the data rate to be printed in bits per second, by
specifying <code>--stats-unit bits</code>. Data transfer volume will
still be reported in bytes.</p>
<p>The rate is reported as a binary unit, not SI unit. So 1 Mbit/s
equals 1,048,576 bit/s and not 1,000,000 bit/s.</p>
<h3 id="suffix-string">--suffix string</h3>
<p>When using <a
href="https://rclone.org/commands/rclone_sync/">sync</a>, <a
href="https://rclone.org/commands/rclone_copy/">copy</a> or <a
href="https://rclone.org/commands/rclone_move/">move</a> any files which
would have been overwritten or deleted will have the suffix added to
them. If there is a file with the same path (after the suffix has been
added), then it will be overwritten.</p>
<p>The remote in use must support server-side move or copy and you must
use the same remote as the destination of the sync.</p>
<p>This is for use with files to add the suffix in the current directory
or with <code>--backup-dir</code>. See <code>--backup-dir</code> for
more info.</p>
<p>For example</p>
<pre class="console"><code>rclone copy --interactive /path/to/local/file remote:current --suffix .bak</code></pre>
<p>will copy <code>/path/to/local</code> to <code>remote:current</code>,
but for any files which would have been updated or deleted have .bak
added.</p>
<p>If using <code>rclone sync</code> with <code>--suffix</code> and
without <code>--backup-dir</code> then it is recommended to put a filter
rule in excluding the suffix otherwise the <code>sync</code> will delete
the backup files.</p>
<pre class="console"><code>rclone sync --interactive /path/to/local/file remote:current --suffix .bak --exclude &quot;*.bak&quot;</code></pre>
<h3 id="suffix-keep-extension">--suffix-keep-extension</h3>
<p>When using <code>--suffix</code>, setting this causes rclone put the
SUFFIX before the extension of the files that it backs up rather than
after.</p>
<p>So let's say we had <code>--suffix -2019-01-01</code>, without the
flag <code>file.txt</code> would be backed up to
<code>file.txt-2019-01-01</code> and with the flag it would be backed up
to <code>file-2019-01-01.txt</code>. This can be helpful to make sure
the suffixed files can still be opened.</p>
<p>If a file has two (or more) extensions and the second (or subsequent)
extension is recognised as a valid mime type, then the suffix will go
before that extension. So <code>file.tar.gz</code> would be backed up to
<code>file-2019-01-01.tar.gz</code> whereas
<code>file.badextension.gz</code> would be backed up to
<code>file.badextension-2019-01-01.gz</code>.</p>
<h3 id="syslog">--syslog</h3>
<p>On capable OSes (not Windows or Plan9) send all log output to
syslog.</p>
<p>This can be useful for running rclone in a script or
<code>rclone mount</code>.</p>
<h3 id="syslog-facility-string">--syslog-facility string</h3>
<p>If using <code>--syslog</code> this sets the syslog facility (e.g.
<code>KERN</code>, <code>USER</code>). See <code>man syslog</code> for a
list of possible facilities. The default facility is
<code>DAEMON</code>.</p>
<h3 id="temp-dir-string">--temp-dir string</h3>
<p>Specify the directory rclone will use for temporary files, to
override the default. Make sure the directory exists and have accessible
permissions.</p>
<p>By default the operating system's temp directory will be used:</p>
<ul>
<li>On Unix systems, <code>$TMPDIR</code> if non-empty, else
<code>/tmp</code>.</li>
<li>On Windows, the first non-empty value from <code>%TMP%</code>,
<code>%TEMP%</code>, <code>%USERPROFILE%</code>, or the Windows
directory.</li>
</ul>
<p>When overriding the default with this option, the specified path will
be set as value of environment variable <code>TMPDIR</code> on Unix
systems and <code>TMP</code> and <code>TEMP</code> on Windows.</p>
<p>You can use the <a
href="https://rclone.org/commands/rclone_config_paths/">config paths</a>
command to see the current value.</p>
<h3 id="tpslimit-float">--tpslimit float</h3>
<p>Limit transactions per second to this number. Default is 0 which is
used to mean unlimited transactions per second.</p>
<p>A transaction is roughly defined as an API call; its exact meaning
will depend on the backend. For HTTP based backends it is an HTTP
PUT/GET/POST/etc and its response. For FTP/SFTP it is a round trip
transaction over TCP.</p>
<p>For example, to limit rclone to 10 transactions per second use
<code>--tpslimit 10</code>, or to 1 transaction every 2 seconds use
<code>--tpslimit 0.5</code>.</p>
<p>Use this when the number of transactions per second from rclone is
causing a problem with the cloud storage provider (e.g. getting you
banned or rate limited).</p>
<p>This can be very useful for <code>rclone mount</code> to control the
behaviour of applications using it.</p>
<p>This limit applies to all HTTP based backends and to the FTP and SFTP
backends. It does not apply to the local backend or the Storj
backend.</p>
<p>See also <code>--tpslimit-burst</code>.</p>
<h3 id="tpslimit-burst-int">--tpslimit-burst int</h3>
<p>Max burst of transactions for <code>--tpslimit</code> (default
<code>1</code>).</p>
<p>Normally <code>--tpslimit</code> will do exactly the number of
transaction per second specified. However if you supply
<code>--tps-burst</code> then rclone can save up some transactions from
when it was idle giving a burst of up to the parameter supplied.</p>
<p>For example if you provide <code>--tpslimit-burst 10</code> then if
rclone has been idle for more than 10*<code>--tpslimit</code> then it
can do 10 transactions very quickly before they are limited again.</p>
<p>This may be used to increase performance of <code>--tpslimit</code>
without changing the long term average number of transactions per
second.</p>
<h3 id="track-renames">--track-renames</h3>
<p>By default, rclone doesn't keep track of renamed files, so if you
rename a file locally then sync it to a remote, rclone will delete the
old file on the remote and upload a new copy.</p>
<p>An rclone sync with <code>--track-renames</code> runs like a normal
sync, but keeps track of objects which exist in the destination but not
in the source (which would normally be deleted), and which objects exist
in the source but not the destination (which would normally be
transferred). These objects are then candidates for renaming.</p>
<p>After the sync, rclone matches up the source only and destination
only objects using the <code>--track-renames-strategy</code> specified
and either renames the destination object or transfers the source and
deletes the destination object. <code>--track-renames</code> is
stateless like all of rclone's syncs.</p>
<p>To use this flag the destination must support server-side copy or
server-side move, and to use a hash based
<code>--track-renames-strategy</code> (the default) the source and the
destination must have a compatible hash.</p>
<p>If the destination does not support server-side copy or move, rclone
will fall back to the default behaviour and log an error level message
to the console.</p>
<p>Encrypted destinations are not currently supported by
<code>--track-renames</code> if <code>--track-renames-strategy</code>
includes <code>hash</code>.</p>
<p>Note that <code>--track-renames</code> is incompatible with
<code>--no-traverse</code> and that it uses extra memory to keep track
of all the rename candidates.</p>
<p>Note also that <code>--track-renames</code> is incompatible with
<code>--delete-before</code> and will select <code>--delete-after</code>
instead of <code>--delete-during</code>.</p>
<h3 id="track-renames-strategy-string">--track-renames-strategy
string</h3>
<p>This option changes the file matching criteria for
<code>--track-renames</code>.</p>
<p>The matching is controlled by a comma separated selection of these
tokens:</p>
<ul>
<li><code>modtime</code> - the modification time of the file - not
supported on all backends</li>
<li><code>hash</code> - the hash of the file contents - not supported on
all backends</li>
<li><code>leaf</code> - the name of the file not including its directory
name</li>
<li><code>size</code> - the size of the file (this is always
enabled)</li>
</ul>
<p>The default option is <code>hash</code>.</p>
<p>Using <code>--track-renames-strategy modtime,leaf</code> would match
files based on modification time, the leaf of the file name and the size
only.</p>
<p>Using <code>--track-renames-strategy modtime</code> or
<code>leaf</code> can enable <code>--track-renames</code> support for
encrypted destinations.</p>
<p>Note that the <code>hash</code> strategy is not supported with
encrypted destinations.</p>
<h3 id="delete-beforeduringafter">--delete-(before,during,after)</h3>
<p>This option allows you to specify when files on your destination are
deleted when you sync folders.</p>
<p>Specifying the value <code>--delete-before</code> will delete all
files present on the destination, but not on the source <em>before</em>
starting the transfer of any new or updated files. This uses two passes
through the file systems, one for the deletions and one for the
copies.</p>
<p>Specifying <code>--delete-during</code> will delete files while
checking and uploading files. This is the fastest option and uses the
least memory.</p>
<p>Specifying <code>--delete-after</code> (the default value) will delay
deletion of files until all new/updated files have been successfully
transferred. The files to be deleted are collected in the copy pass then
deleted after the copy pass has completed successfully. The files to be
deleted are held in memory so this mode may use more memory. This is the
safest mode as it will only delete files if there have been no errors
subsequent to that. If there have been errors before the deletions start
then you will get the message
<code>not deleting files as there were IO errors</code>.</p>
<h3 id="fast-list">--fast-list</h3>
<p>When doing anything which involves a directory listing (e.g.
<code>sync</code>, <code>copy</code>, <code>ls</code> - in fact nearly
every command), rclone has different strategies to choose from.</p>
<p>The basic strategy is to list one directory and processes it before
using more directory lists to process any subdirectories. This is a
mandatory backend feature, called <code>List</code>, which means it is
supported by all backends. This strategy uses small amount of memory,
and because it can be parallelised it is fast for operations involving
processing of the list results.</p>
<p>Some backends provide the support for an alternative strategy, where
all files beneath a directory can be listed in one (or a small number)
of transactions. Rclone supports this alternative strategy through an
optional backend feature called <a
href="https://rclone.org/overview/#listr"><code>ListR</code></a>. You
can see in the storage system overview documentation's <a
href="https://rclone.org/overview/#optional-features">optional
features</a> section which backends it is enabled for (these tend to be
the bucket-based ones, e.g. S3, B2, GCS, Swift). This strategy requires
fewer transactions for highly recursive operations, which is important
on backends where this is charged or heavily rate limited. It may be
faster (due to fewer transactions) or slower (because it can't be
parallelized) depending on different parameters, and may require more
memory if rclone has to keep the whole listing in memory.</p>
<p>Which listing strategy rclone picks for a given operation is
complicated, but in general it tries to choose the best possible. It
will prefer <code>ListR</code> in situations where it doesn't need to
store the listed files in memory, e.g. for unlimited recursive
<code>ls</code> command variants. In other situations it will prefer
<code>List</code>, e.g. for <code>sync</code> and <code>copy</code>,
where it needs to keep the listed files in memory, and is performing
operations on them where parallelization may be a huge advantage.</p>
<p>Rclone is not able to take all relevant parameters into account for
deciding the best strategy, and therefore allows you to influence the
choice in two ways: You can stop rclone from using <code>ListR</code> by
disabling the feature, using the <a href="#disable-string">--disable</a>
option (<code>--disable ListR</code>), or you can allow rclone to use
<code>ListR</code> where it would normally choose not to do so due to
higher memory usage, using the <code>--fast-list</code> option. Rclone
should always produce identical results either way. Using
<code>--disable ListR</code> or <code>--fast-list</code> on a remote
which doesn't support <code>ListR</code> does nothing, rclone will just
ignore it.</p>
<p>A rule of thumb is that if you pay for transactions and can fit your
entire sync listing into memory, then <code>--fast-list</code> is
recommended. If you have a very big sync to do, then don't use
<code>--fast-list</code>, otherwise you will run out of memory. Run some
tests and compare before you decide, and if in doubt then just leave the
default, let rclone decide, i.e. not use <code>--fast-list</code>.</p>
<h3 id="timeout-duration">--timeout Duration</h3>
<p>This sets the IO idle timeout. If a transfer has started but then
becomes idle for this long it is considered broken and disconnected.</p>
<p>The default is <code>5m</code>. Set to <code>0</code> to disable.</p>
<h3 id="transfers-int">--transfers int</h3>
<p>The number of file transfers to run in parallel. It can sometimes be
useful to set this to a smaller number if the remote is giving a lot of
timeouts or bigger if you have lots of bandwidth and a fast remote.</p>
<p>The default is to run 4 file transfers in parallel.</p>
<p>Look at --multi-thread-streams if you would like to control single
file transfers.</p>
<h3 id="u---update">-u, --update</h3>
<p>This forces rclone to skip any files which exist on the destination
and have a modified time that is newer than the source file.</p>
<p>This can be useful in avoiding needless transfers when transferring
to a remote which doesn't support modification times directly (or when
using <code>--use-server-modtime</code> to avoid extra API calls) as it
is more accurate than a <code>--size-only</code> check and faster than
using <code>--checksum</code>. On such remotes (or when using
<code>--use-server-modtime</code>) the time checked will be the uploaded
time.</p>
<p>If an existing destination file has a modification time older than
the source file's, it will be updated if the sizes are different. If the
sizes are the same, it will be updated if the checksum is different or
not available.</p>
<p>If an existing destination file has a modification time equal (within
the computed modify window) to the source file's, it will be updated if
the sizes are different. The checksum will not be checked in this case
unless the <code>--checksum</code> flag is provided.</p>
<p>In all other cases the file will not be updated.</p>
<p>Consider using the <code>--modify-window</code> flag to compensate
for time skews between the source and the backend, for backends that do
not support mod times, and instead use uploaded times. However, if the
backend does not support checksums, note that syncing or copying within
the time skew window may still result in additional transfers for
safety.</p>
<h3 id="use-mmap">--use-mmap</h3>
<p>If this flag is set then rclone will use anonymous memory allocated
by mmap on Unix based platforms and VirtualAlloc on Windows for its
transfer buffers (size controlled by <code>--buffer-size</code>). Memory
allocated like this does not go on the Go heap and can be returned to
the OS immediately when it is finished with.</p>
<p>If this flag is not set then rclone will allocate and free the
buffers using the Go memory allocator which may use more memory as
memory pages are returned less aggressively to the OS.</p>
<p>It is possible this does not work well on all platforms so it is
disabled by default; in the future it may be enabled by default.</p>
<h3 id="use-server-modtime">--use-server-modtime</h3>
<p>Some object-store backends (e.g, Swift, S3) do not preserve file
modification times (modtime). On these backends, rclone stores the
original modtime as additional metadata on the object. By default it
will make an API call to retrieve the metadata when the modtime is
needed by an operation.</p>
<p>Use this flag to disable the extra API call and rely instead on the
server's modified time. In cases such as a local to remote sync using
<code>--update</code>, knowing the local file is newer than the time it
was last uploaded to the remote is sufficient. In those cases, this flag
can speed up the process and reduce the number of API calls
necessary.</p>
<p>Using this flag on a sync operation without also using
<code>--update</code> would cause all files modified at any time other
than the last upload time to be uploaded again, which is probably not
what you want.</p>
<h3 id="v--vv---verbose">-v, -vv, --verbose</h3>
<p>With <code>-v</code> rclone will tell you about each file that is
transferred and a small number of significant events.</p>
<p>With <code>-vv</code> rclone will become very verbose telling you
about every file it considers and transfers. Please send bug reports
with a log with this setting.</p>
<p>When setting verbosity as an environment variable, use
<code>RCLONE_VERBOSE=1</code> or <code>RCLONE_VERBOSE=2</code> for
<code>-v</code> and <code>-vv</code> respectively.</p>
<h3 id="v---version">-V, --version</h3>
<p>Prints the version number</p>
<h2 id="ssltls-options">SSL/TLS options</h2>
<p>The outgoing SSL/TLS connections rclone makes can be controlled with
these options. For example this can be very useful with the HTTP or
WebDAV backends. Rclone HTTP servers have their own set of configuration
for SSL/TLS which you can find in their documentation.</p>
<h3 id="ca-cert-stringarray">--ca-cert stringArray</h3>
<p>This loads the PEM encoded certificate authority certificates and
uses it to verify the certificates of the servers rclone connects
to.</p>
<p>If you have generated certificates signed with a local CA then you
will need this flag to connect to servers using those certificates.</p>
<h3 id="client-cert-string">--client-cert string</h3>
<p>This loads the PEM encoded client side certificate.</p>
<p>This is used for <a
href="https://en.wikipedia.org/wiki/Mutual_authentication">mutual TLS
authentication</a>.</p>
<p>The <code>--client-key</code> flag is required too when using
this.</p>
<h3 id="client-key-string">--client-key string</h3>
<p>This loads the PEM encoded client side private key used for mutual
TLS authentication. Used in conjunction with
<code>--client-cert</code>.</p>
<p>Supported types are:</p>
<ul>
<li>Unencrypted PKCS#1 ("BEGIN RSA PRIVATE KEY")</li>
<li>Unencrypted PKCS#8 ("BEGIN PRIVATE KEY")</li>
<li>Encrypted PKCS#8 ("BEGIN ENCRYPTED PRIVATE KEY")</li>
<li>Legacy PEM encryption (e.g., DEK-Info headers), which are
automatically detected.</li>
</ul>
<h3 id="client-pass-string">--client-pass string</h3>
<p>This can be used to supply an optional password to decrypt the client
key file.</p>
<p><strong>NB</strong> the password should be obscured so it should be
the output of <code>rclone obscure YOURPASSWORD</code>.</p>
<h3 id="no-check-certificate">--no-check-certificate</h3>
<p><code>--no-check-certificate</code> controls whether a client
verifies the server's certificate chain and host name. If
<code>--no-check-certificate</code> is true, TLS accepts any certificate
presented by the server and any host name in that certificate. In this
mode, TLS is susceptible to man-in-the-middle attacks.</p>
<p>This option defaults to <code>false</code>.</p>
<p><strong>This should be used only for testing.</strong></p>
<h2 id="configuration-encryption">Configuration encryption</h2>
<p>Your configuration file contains information for logging in to your
cloud services. This means that you should keep your
<code>rclone.conf</code> file in a secure location.</p>
<p>If you are in an environment where that isn't possible, you can add a
password to your configuration. This means that you will have to supply
the password every time you start rclone.</p>
<p>To add a password to your rclone configuration, execute
<code>rclone config</code>.</p>
<pre class="console"><code>$ rclone config
Current remotes:

e) Edit existing remote
n) New remote
d) Delete remote
s) Set configuration password
q) Quit config
e/n/d/s/q&gt;</code></pre>
<p>Go into <code>s</code>, Set configuration password:</p>
<pre class="text"><code>e/n/d/s/q&gt; s
Your configuration is not encrypted.
If you add a password, you will protect your login information to cloud services.
a) Add Password
q) Quit to main menu
a/q&gt; a
Enter NEW configuration password:
password:
Confirm NEW password:
password:
Password set
Your configuration is encrypted.
c) Change Password
u) Unencrypt configuration
q) Quit to main menu
c/u/q&gt;</code></pre>
<p>Your configuration is now encrypted, and every time you start rclone
you will have to supply the password. See below for details. In the same
menu, you can change the password or completely remove encryption from
your configuration.</p>
<p>There is no way to recover the configuration if you lose your
password.</p>
<p>You can also use</p>
<ul>
<li><a
href="https://rclone.org/commands/rclone_config_encryption_set/">rclone
config encryption set</a> to set the config encryption directly</li>
<li><a
href="https://rclone.org/commands/rclone_config_encryption_remove/">rclone
config encryption remove</a> to remove it</li>
<li><a
href="https://rclone.org/commands/rclone_config_encryption_check/">rclone
config encryption check</a> to check that it is encrypted properly.</li>
</ul>
<p>rclone uses <a
href="https://godoc.org/golang.org/x/crypto/nacl/secretbox">nacl
secretbox</a> which in turn uses XSalsa20 and Poly1305 to encrypt and
authenticate your configuration with secret-key cryptography. The
password is SHA-256 hashed, which produces the key for secretbox. The
hashed password is not stored.</p>
<p>While this provides very good security, we do not recommend storing
your encrypted rclone configuration in public if it contains sensitive
information, maybe except if you use a very strong password.</p>
<p>If it is safe in your environment, you can set the
<code>RCLONE_CONFIG_PASS</code> environment variable to contain your
password, in which case it will be used for decrypting the
configuration.</p>
<p>You can set this for a session from a script. For unix like systems
save this to a file called <code>set-rclone-password</code>:</p>

<p>Then source the file when you want to use it. From the shell you
would do <code>source set-rclone-password</code>. It will then ask you
for the password and set it in the environment variable.</p>
<p>An alternate means of supplying the password is to provide a script
which will retrieve the password and print on standard output. This
script should have a fully specified path name and not rely on any
environment variables. The script is supplied either via <a
href="#password-command"><code>--password-command="..."</code></a>
command line argument or via the <code>RCLONE_PASSWORD_COMMAND</code>
environment variable.</p>
<p>One useful example of this is using the <code>passwordstore</code>
application to retrieve the password:</p>
<pre class="console"><code>export RCLONE_PASSWORD_COMMAND=&quot;pass rclone/config&quot;</code></pre>
<p>If the <code>passwordstore</code> password manager holds the password
for the rclone configuration, using the script method means the password
is primarily protected by the <code>passwordstore</code> system, and is
never embedded in the clear in scripts, nor available for examination
using the standard commands available. It is quite possible with long
running rclone sessions for copies of passwords to be innocently
captured in log files or terminal scroll buffers, etc. Using the script
method of supplying the password enhances the security of the config
password considerably.</p>
<p>If you are running rclone inside a script, unless you are using the
<code>--password-command</code> method, you might want to disable
password prompts. To do that, pass the parameter
<code>--ask-password=false</code> to rclone. This will make rclone fail
instead of asking for a password if <code>RCLONE_CONFIG_PASS</code>
doesn't contain a valid password, and <code>--password-command</code>
has not been supplied.</p>
<p>Whenever running commands that may be affected by options in a
configuration file, rclone will look for an existing file according to
the rules described <a href="#config-string">above</a>, and load any it
finds. If an encrypted file is found, this includes decrypting it, with
the possible consequence of a password prompt. When executing a command
line that you know are not actually using anything from such a
configuration file, you can avoid it being loaded by overriding the
location, e.g. with one of the documented special values for memory-only
configuration. Since only backend options can be stored in configuration
files, this is normally unnecessary for commands that do not operate on
backends, e.g. <code>completion</code>. However, it will be relevant for
commands that do operate on backends in general, but are used without
referencing a stored remote, e.g. listing local filesystem paths, or <a
href="#connection-strings">connection strings</a>:
<code>rclone --config="" ls .</code></p>

<p>These options are useful when developing or debugging rclone. There
are also some more remote specific options which aren't documented here
which are used for testing. These start with remote name e.g.
<code>--drive-test-option</code> - see the docs for the remote in
question.</p>
<h3 id="cpuprofile-string">--cpuprofile string</h3>
<p>Write CPU profile to a file. This can be analysed with

<p>Write memory profile to a file. This can be analysed with
<code>go tool pprof</code>.</p>
<h3 id="dump-dumpflags">--dump DumpFlags</h3>
<p>The <code>--dump</code> flag takes a comma separated list of flags to
dump info about.</p>
<p>Note that some headers, such as <code>Accept-Encoding</code>, may not
be correct as shown in the request, and the response may not show
<code>Content-Encoding</code> if the go standard libraries auto gzip
encoding was in effect. In this case the body of the request will be
gunzipped before showing it.</p>
<p>The available flags are:</p>
<ul>
<li><code>headers</code> dumps HTTP headers. Any
<code>Authorization:</code> headers will be excluded, but output may
still contain sensitive information. Can be very verbose. Useful for
debugging only. Use <code>auth</code> if you do want the
<code>Authorization:</code> headers.</li>
<li><code>auth</code> dumps HTTP headers like <code>headers</code>, but
also includes any <code>Authorization:</code> headers. This means the
output will probably contain sensitive information. Use
<code>headers</code> to dump without <code>Authorization:</code>
headers. Can be very verbose. Useful for debugging only.</li>
<li><code>bodies</code> dumps HTTP headers and bodies. May contain
sensitive info. Can be very verbose. Useful for debugging only. Note
that the bodies are buffered in memory so don't use this for enormous
files.</li>
<li><code>requests</code> is similar to <code>bodies</code>, but dumps
the request bodies and the response headers. Useful for debugging
download problems.</li>
<li><code>responses</code> is similar to <code>bodies</code>, but dumps
the response bodies and the request headers. Useful for debugging upload
problems.</li>
<li><code>filters</code> dumps the filters. Useful to see exactly what
include and exclude options are filtering on.</li>
<li><code>goroutines</code> dumps a list of the running go-routines at
the end of the command.</li>
<li><code>openfiles</code> dumps a list of the open files at the end of
the command. It uses the <code>lsof</code> Unix command to do that, so
you'll need that installed to use it.</li>
<li><code>mapper</code> dumps the JSON blobs being sent to the program
supplied with <code>--metadata-mapper</code> and received from it. It
can be useful for debugging the metadata mapper interface.</li>
</ul>

<h2 id="remote-control">Remote control</h2>
<p>For the remote control options and for instructions on how to remote
control rclone:</p>
<ul>
<li><code>--rc</code></li>
<li>Anything starting with <code>--rc-</code></li>
</ul>
<p>See <a href="https://rclone.org/rc/">the remote control
section</a>.</p>
<h2 id="logging">Logging</h2>
<p>rclone has 4 levels of logging, <code>ERROR</code>,
<code>NOTICE</code>, <code>INFO</code> and <code>DEBUG</code>.</p>
<p>By default, rclone logs to standard error. This means you can
redirect standard error and still see the normal output of rclone
commands (e.g. <code>rclone ls</code>).</p>
<p>By default, rclone will produce <code>Error</code> and
<code>Notice</code> level messages.</p>
<p>If you use the <code>-q</code> flag, rclone will only produce
<code>Error</code> messages.</p>
<p>If you use the <code>-v</code> flag, rclone will produce
<code>Error</code>, <code>Notice</code> and <code>Info</code>
messages.</p>
<p>If you use the <code>-vv</code> flag, rclone will produce
<code>Error</code>, <code>Notice</code>, <code>Info</code> and
<code>Debug</code> messages.</p>
<p>You can also control the log levels with the <code>--log-level</code>
flag.</p>
<p>If you use the <code>--log-file</code> option, rclone will redirect
<code>Error</code>, <code>Info</code> and <code>Debug</code> messages
along with standard error to a file.</p>
<p>If you use the <code>--syslog</code> flag then rclone will log to
syslog and the <code>--syslog-facility</code> control which facility it
uses.</p>
<p>Rclone prefixes all log messages with their level in capitals, e.g.
INFO which makes it easy to grep the log file for different kinds of
information.</p>
<h2 id="metrics">Metrics</h2>
<p>Rclone can publish metrics in the OpenMetrics/Prometheus format.</p>
<p>To enable the metrics endpoint, use the <code>--metrics-addr</code>
flag. Metrics can also be published on the <code>--rc-addr</code> port
if the <code>--rc</code> flag and <code>--rc-enable-metrics</code> flags
are supplied or if using rclone rcd <code>--rc-enable-metrics</code></p>
<p>Rclone provides extensive configuration options for the metrics HTTP
endpoint. These settings are grouped under the Metrics section and have
a prefix <code>--metrics-*</code>.</p>
<p>When metrics are enabled with <code>--rc-enable-metrics</code>, they
will be published on the same port as the rc API. In this case, the
<code>--metrics-*</code> flags will be ignored, and the HTTP endpoint
configuration will be managed by the <code>--rc-*</code> parameters.</p>
<h2 id="exit-code">Exit code</h2>
<p>If any errors occur during the command execution, rclone will exit
with a non-zero exit code. This allows scripts to detect when rclone
operations have failed.</p>
<p>During the startup phase, rclone will exit immediately if an error is
detected in the configuration. There will always be a log message
immediately before exiting.</p>
<p>When rclone is running it will accumulate errors as it goes along,
and only exit with a non-zero exit code if (after retries) there were
still failed transfers. For every error counted there will be a high
priority log message (visible with <code>-q</code>) showing the message
and which file caused the problem. A high priority message is also shown
when starting a retry so the user can see that any previous error
messages may not be valid after the retry. If rclone has done a retry it
will log a high priority message if the retry was successful.</p>
<h3 id="list-of-exit-codes">List of exit codes</h3>
<ul>
<li><code>0</code> - Success</li>
<li><code>1</code> - Error not otherwise categorised</li>
<li><code>2</code> - Syntax or usage error</li>
<li><code>3</code> - Directory not found</li>
<li><code>4</code> - File not found</li>
<li><code>5</code> - Temporary error (one that more retries might fix)
(Retry errors)</li>
<li><code>6</code> - Less serious errors (like 461 errors from dropbox)
(NoRetry errors)</li>
<li><code>7</code> - Fatal error (one that more retries won't fix, like
account suspended) (Fatal errors)</li>
<li><code>8</code> - Transfer exceeded - limit set by --max-transfer
reached</li>
<li><code>9</code> - Operation successful, but no files transferred
(Requires <a
href="#error-on-no-transfer"><code>--error-on-no-transfer</code></a>)</li>
<li><code>10</code> - Duration exceeded - limit set by --max-duration
reached</li>
</ul>
<h2 id="environment-variables">Environment variables</h2>
<p>Rclone can be configured entirely using environment variables. These
can be used to set defaults for options or config file entries.</p>
<h3 id="options-98">Options</h3>
<p>Every option in rclone can have its default set by environment
variable.</p>
<p>To find the name of the environment variable, first, take the long
option name, strip the leading <code>--</code>, change <code>-</code> to
<code>_</code>, make upper case and prepend <code>RCLONE_</code>.</p>
<p>For example, to always set <code>--stats 5s</code>, set the
environment variable <code>RCLONE_STATS=5s</code>. If you set stats on
the command line this will override the environment variable
setting.</p>
<p>Or to always use the trash in drive <code>--drive-use-trash</code>,
set <code>RCLONE_DRIVE_USE_TRASH=true</code>.</p>
<p>Verbosity is slightly different, the environment variable equivalent
of <code>--verbose</code> or <code>-v</code> is
<code>RCLONE_VERBOSE=1</code>, or for <code>-vv</code>,
<code>RCLONE_VERBOSE=2</code>.</p>
<p>The same parser is used for the options and the environment variables
so they take exactly the same form.</p>
<p>The options set by environment variables can be seen with the
<code>-vv</code> flag, e.g. <code>rclone version -vv</code>.</p>
<p>Options that can appear multiple times (type
<code>stringArray</code>) are treated slightly differently as
environment variables can only be defined once. In order to allow a
simple mechanism for adding one or many items, the input is treated as a
<a href="https://godoc.org/encoding/csv">CSV encoded</a> string. For
example</p>
<table>
<colgroup>
<col style="width: 52%" />
<col style="width: 47%" />
</colgroup>
<thead>
<tr class="header">
<th>Environment variable</th>
<th>Equivalent options</th>
</tr>
</thead>
<tbody>
<tr class="odd">
<td><code>RCLONE_EXCLUDE="*.jpg"</code></td>
<td><code>--exclude "*.jpg"</code></td>
</tr>
<tr class="even">
<td><code>RCLONE_EXCLUDE="*.jpg,*.png"</code></td>
<td><code>--exclude "*.jpg"</code> <code>--exclude "*.png"</code></td>
</tr>
<tr class="odd">
<td><code>RCLONE_EXCLUDE='"*.jpg","*.png"'</code></td>
<td><code>--exclude "*.jpg"</code> <code>--exclude "*.png"</code></td>
</tr>
<tr class="even">
<td><code>RCLONE_EXCLUDE='"/directory with comma , in it /**"'</code></td>
<td>`--exclude "/directory with comma , in it /**"</td>
</tr>
</tbody>
</table>
<p>If <code>stringArray</code> options are defined as environment
variables <strong>and</strong> options on the command line then all the
values will be used.</p>
<h3 id="config-file">Config file</h3>
<p>You can set defaults for values in the config file on an individual
remote basis. The names of the config items are documented in the page
for each backend.</p>
<p>To find the name of the environment variable, you need to set, take
<code>RCLONE_CONFIG_</code> + name of remote + <code>_</code> + name of
config file option and make it all uppercase. Note one implication here
is the remote's name must be convertible into a valid environment
variable name, so it can only contain letters, digits, or the
<code>_</code> (underscore) character.</p>
<p>For example, to configure an S3 remote named <code>mys3:</code>
without a config file (using unix ways of setting environment
variables):</p>
<pre class="console"><code>$ export RCLONE_CONFIG_MYS3_TYPE=s3
$ export RCLONE_CONFIG_MYS3_ACCESS_KEY_ID=XXX
$ export RCLONE_CONFIG_MYS3_SECRET_ACCESS_KEY=XXX
$ rclone lsd mys3:
          -1 2016-09-21 12:54:21        -1 my-bucket
$ rclone listremotes | grep mys3
mys3:</code></pre>
<p>Note that if you want to create a remote using environment variables
you must create the <code>..._TYPE</code> variable as above.</p>
<p>Note that the name of a remote created using environment variable is
case insensitive, in contrast to regular remotes stored in config file
as documented <a href="#valid-remote-names">above</a>. You must write
the name in uppercase in the environment variable, but as seen from
example above it will be listed and can be accessed in lowercase, while
you can also refer to the same remote in uppercase:</p>
<pre class="console"><code>$ rclone lsd mys3:
          -1 2016-09-21 12:54:21        -1 my-bucket
$ rclone lsd MYS3:
          -1 2016-09-21 12:54:21        -1 my-bucket</code></pre>
<p>Note that you can only set the options of the immediate backend, so
RCLONE_CONFIG_MYS3CRYPT_ACCESS_KEY_ID has no effect, if myS3Crypt is a
crypt remote based on an S3 remote. However RCLONE_S3_ACCESS_KEY_ID will
set the access key of all remotes using S3, including myS3Crypt.</p>
<p>Note also that now rclone has <a
href="#connection-strings">connection strings</a>, it is probably easier
to use those instead which makes the above example</p>
<pre class="console"><code>rclone lsd :s3,access_key_id=XXX,secret_access_key=XXX:</code></pre>
<h3 id="precedence">Precedence</h3>
<p>The various different methods of backend configuration are read in
this order and the first one with a value is used.</p>
<ul>
<li>Parameters in connection strings, e.g.
<code>myRemote,skip_links:</code></li>
<li>Flag values as supplied on the command line, e.g.
<code>--skip-links</code></li>
<li>Remote specific environment vars, e.g.
<code>RCLONE_CONFIG_MYREMOTE_SKIP_LINKS</code> (see above).</li>
<li>Backend-specific environment vars, e.g.
<code>RCLONE_LOCAL_SKIP_LINKS</code>.</li>
<li>Backend generic environment vars, e.g.
<code>RCLONE_SKIP_LINKS</code>.</li>
<li>Config file, e.g. <code>skip_links = true</code>.</li>
<li>Default values, e.g. <code>false</code> - these can't be
changed.</li>
</ul>
<p>So if both <code>--skip-links</code> is supplied on the command line
and an environment variable <code>RCLONE_LOCAL_SKIP_LINKS</code> is set,
the command line flag will take preference.</p>
<p>The backend configurations set by environment variables can be seen
with the <code>-vv</code> flag, e.g.
<code>rclone about myRemote: -vv</code>.</p>
<p>For non backend configuration the order is as follows:</p>
<ul>
<li>Flag values as supplied on the command line, e.g.
<code>--stats 5s</code>.</li>
<li>Environment vars, e.g. <code>RCLONE_STATS=5s</code>.</li>
<li>Default values, e.g. <code>1m</code> - these can't be changed.</li>
</ul>
<h3 id="other-environment-variables">Other environment variables</h3>
<ul>
<li><code>RCLONE_CONFIG_PASS</code> set to contain your config file
password (see <a href="#configuration-encryption">Configuration
Encryption</a> section)</li>
<li><code>HTTP_PROXY</code>, <code>HTTPS_PROXY</code> and
<code>NO_PROXY</code> (or the lowercase versions thereof).
<ul>
<li><code>HTTPS_PROXY</code> takes precedence over
<code>HTTP_PROXY</code> for https requests.</li>
<li>The environment values may be either a complete URL or a
"host[:port]" for, in which case the "http" scheme is assumed.</li>
</ul></li>
<li><code>USER</code> and <code>LOGNAME</code> values are used as
fallbacks for current username. The primary method for looking up
username is OS-specific: Windows API on Windows, real user ID in
/etc/passwd on Unix systems. In the documentation the current username
is simply referred to as <code>$USER</code>.</li>
<li><code>RCLONE_CONFIG_DIR</code> - rclone <strong>sets</strong> this
variable for use in config files and sub processes to point to the
directory holding the config file.</li>
</ul>
<p>The options set by environment variables can be seen with the
<code>-vv</code> and <code>--log-level=DEBUG</code> flags, e.g.
<code>rclone version -vv</code>.</p>
<h1 id="configuring-rclone-on-a-remote-headless-machine">Configuring
rclone on a remote / headless machine</h1>
<p>Some of the configurations (those involving oauth2) require an
internet-connected web browser.</p>
<p>If you are trying to set rclone up on a remote or headless machine
with no browser available on it (e.g. a NAS or a server in a
datacenter), then you will need to use an alternative means of
configuration. There are three ways of doing it, described below.</p>
<h2 id="configuring-using-rclone-authorize">Configuring using rclone

Execute the following on the machine with the web browser (same rclone
version recommended):
        rclone authorize &quot;onedrive&quot;
Then paste the result.
Enter a value.

y/e/d&gt;</code></pre>
<h2 id="configuring-by-copying-the-config-file">Configuring by copying
the config file</h2>
<p>Rclone stores all of its configuration in a single file. This can
easily be copied to configure a remote rclone (although some backends
does not support reusing the same configuration, consult your backend
documentation to be sure).</p>
<p>Start by running <a href="/commands/rclone_config">rclone config</a>
to create the configuration file on your desktop machine.</p>
<pre class="console"><code>rclone config</code></pre>
<p>Then locate the file by running <a
href="/commands/rclone_config_file">rclone config file</a>.</p>
<pre class="console"><code>$ rclone config file
Configuration file is stored at:
/home/user/.rclone.conf</code></pre>
<p>Finally, transfer the file to the remote machine (scp, cut paste,
ftp, sftp, etc.) and place it in the correct location (use <a
href="/commands/rclone_config_file">rclone config file</a> on the remote
machine to find out where).</p>
<h2 id="configuring-using-ssh-tunnel">Configuring using SSH Tunnel</h2>
<p>If you have an SSH client installed on your local machine, you can
set up an SSH tunnel to redirect the port 53682 into the headless
machine by using the following command:</p>
<pre class="console"><code>ssh -L localhost:53682:localhost:53682 username@remote_server</code></pre>
<p>Then on the headless machine run <a

<code>Y</code> to the question
<code>Use web browser to automatically authenticate rclone with remote?</code>.</p>
<pre class="text"><code>Use web browser to automatically authenticate rclone with remote?

<h1 id="filtering-includes-and-excludes">Filtering, includes and
excludes</h1>
<p>Filter flags determine which files rclone <code>sync</code>,
<code>move</code>, <code>ls</code>, <code>lsl</code>,
<code>md5sum</code>, <code>sha1sum</code>, <code>size</code>,
<code>delete</code>, <code>check</code> and similar commands apply
to.</p>
<p>They are specified in terms of path/file name patterns; path/file
lists; file age and size, or presence of a file in a directory. Bucket
based remotes without the concept of directory apply filters to object
key, age and size in an analogous way.</p>
<p>Rclone <code>purge</code> does not obey filters.</p>
<p>To test filters without risk of damage to data, apply them to
<code>rclone ls</code>, or with the <code>--dry-run</code> and
<code>-vv</code> flags.</p>
<p>Rclone filter patterns can only be used in filter command line
options, not in the specification of a remote.</p>
<p>E.g. <code>rclone copy "remote:dir*.jpg" /path/to/dir</code> does not
have a filter effect.
<code>rclone copy remote:dir /path/to/dir --include "*.jpg"</code>
does.</p>
<p><strong>Important</strong> Avoid mixing any two of
<code>--include...</code>, <code>--exclude...</code> or
<code>--filter...</code> flags in an rclone command. The results might
not be what you expect. Instead use a <code>--filter...</code> flag.</p>
<h2 id="patterns-for-matching-pathfile-names">Patterns for matching
path/file names</h2>
<h3 id="patterns">Pattern syntax</h3>
<p>Here is a formal definition of the pattern syntax, <a
href="#examples">examples</a> are below.</p>
<p>Rclone matching rules follow a glob style:</p>
<pre class="text"><code>*         matches any sequence of non-separator (/) characters
**        matches any sequence of characters including / separators
?         matches any single non-separator (/) character
[ [ ! ] { character-range } ]
          character class (must be non-empty)
{ pattern-list }
          pattern alternatives
{{ regexp }}
          regular expression to match
c         matches character c (c != *, **, ?, \, [, {, })
\c        matches reserved character c (c = *, **, ?, \, [, {, }) or character class</code></pre>
<p>character-range:</p>
<pre class="text"><code>c         matches character c (c != \, -, ])
\c        matches reserved character c (c = \, -, ])
lo - hi   matches character c for lo &lt;= c &lt;= hi</code></pre>
<p>pattern-list:</p>
<pre class="text"><code>pattern { , pattern }
          comma-separated (without spaces) patterns</code></pre>
<p>character classes (see <a
href="https://golang.org/pkg/regexp/syntax/">Go regular expression
reference</a>) include:</p>
<pre class="text"><code>Named character classes (e.g. [\d], [^\d], [\D], [^\D])
Perl character classes (e.g. \s, \S, \w, \W)
ASCII character classes (e.g. [[:alnum:]], [[:alpha:]], [[:punct:]], [[:xdigit:]])</code></pre>
<p>regexp for advanced users to insert a regular expression - see <a
href="#regexp">below</a> for more info:</p>
<pre class="text"><code>Any re2 regular expression not containing `}}`</code></pre>
<p>If the filter pattern starts with a <code>/</code> then it only
matches at the top level of the directory tree, <strong>relative to the
root of the remote</strong> (not necessarily the root of the drive). If
it does not start with <code>/</code> then it is matched starting at the
<strong>end of the path/file name</strong> but it only matches a
complete path element - it must match from a <code>/</code> separator or
the beginning of the path/file.</p>
<pre class="text"><code>file.jpg   - matches &quot;file.jpg&quot;
           - matches &quot;directory/file.jpg&quot;
           - doesn&#39;t match &quot;afile.jpg&quot;
           - doesn&#39;t match &quot;directory/afile.jpg&quot;
/file.jpg  - matches &quot;file.jpg&quot; in the root directory of the remote
           - doesn&#39;t match &quot;afile.jpg&quot;
           - doesn&#39;t match &quot;directory/file.jpg&quot;</code></pre>
<p>The top level of the remote might not be the top level of the
drive.</p>
<p>E.g. for a Microsoft Windows local directory structure</p>
<pre class="text"><code>F:
├── bkp
├── data
│   ├── excl
│   │   ├── 123.jpg
│   │   └── 456.jpg
│   ├── incl
│   │   └── document.pdf</code></pre>
<p>To copy the contents of folder <code>data</code> into folder
<code>bkp</code> excluding the contents of subfolder
<code>excl</code>the following command treats <code>F:\data</code> and
<code>F:\bkp</code> as top level for filtering.</p>
<p><code>rclone copy F:\data\ F:\bkp\ --exclude=/excl/**</code></p>
<p><strong>Important</strong> Use <code>/</code> in path/file name
patterns and not <code>\</code> even if running on Microsoft
Windows.</p>
<p>Simple patterns are case sensitive unless the
<code>--ignore-case</code> flag is used.</p>
<p>Without <code>--ignore-case</code> (default)</p>
<pre class="text"><code>potato - matches &quot;potato&quot;
       - doesn&#39;t match &quot;POTATO&quot;</code></pre>
<p>With <code>--ignore-case</code></p>
<pre class="text"><code>potato - matches &quot;potato&quot;
       - matches &quot;POTATO&quot;</code></pre>
<h2 id="regexp">Using regular expressions in filter patterns</h2>
<p>The syntax of filter patterns is glob style matching (like
<code>bash</code> uses) to make things easy for users. However this does
not provide absolute control over the matching, so for advanced users
rclone also provides a regular expression syntax.</p>
<p>Rclone generally accepts Perl-style regular expressions, the exact
syntax is defined in the <a
href="https://golang.org/pkg/regexp/syntax/">Go regular expression
reference</a>. Regular expressions should be enclosed in <code>{{</code>
<code>}}</code>. They will match only the last path segment if the glob
doesn't start with <code>/</code> or the whole path name if it does.
Note that rclone does not attempt to parse the supplied regular
expression, meaning that using any regular expression filter will
prevent rclone from using <a href="#directory_filter">directory filter
rules</a>, as it will instead check every path against the supplied
regular expression(s).</p>
<p>Here is how the <code>{{regexp}}</code> is transformed into an full
regular expression to match the entire path:</p>
<pre class="text"><code>{{regexp}}  becomes (^|/)(regexp)$
/{{regexp}} becomes ^(regexp)$</code></pre>
<p>Regexp syntax can be mixed with glob syntax, for example</p>
<pre class="text"><code>*.{{jpe?g}} to match file.jpg, file.jpeg but not file.png</code></pre>
<p>You can also use regexp flags - to set case insensitive, for
example</p>
<pre class="text"><code>*.{{(?i)jpg}} to match file.jpg, file.JPG but not file.png</code></pre>
<p>Be careful with wildcards in regular expressions - you don't want
them to match path separators normally. To match any file name starting
with <code>start</code> and ending with <code>end</code> write</p>
<pre class="text"><code>{{start[^/]*end\.jpg}}</code></pre>
<p>Not</p>
<pre class="text"><code>{{start.*end\.jpg}}</code></pre>
<p>Which will match a directory called <code>start</code> with a file
called <code>end.jpg</code> in it as the <code>.*</code> will match
<code>/</code> characters.</p>
<p>Note that you can use <code>-vv --dump filters</code> to show the
filter patterns in regexp format - rclone implements the glob patterns
by transforming them into regular expressions.</p>

<h2 id="how-filter-rules-work">How filter rules are applied to
files</h2>
<p>Rclone path/file name filters are made up of one or more of the
following flags:</p>
<ul>
<li><code>--include</code></li>
<li><code>--include-from</code></li>
<li><code>--exclude</code></li>
<li><code>--exclude-from</code></li>
<li><code>--filter</code></li>
<li><code>--filter-from</code></li>
</ul>
<p>There can be more than one instance of individual flags.</p>
<p>Rclone internally uses a combined list of all the include and exclude
rules. The order in which rules are processed can influence the result
of the filter.</p>
<p>All flags of the same type are processed together in the order above,
regardless of what order the different types of flags are included on
the command line.</p>
<p>Multiple instances of the same flag are processed from left to right
according to their position in the command line.</p>
<p>To mix up the order of processing includes and excludes use
<code>--filter...</code> flags.</p>
<p>Within <code>--include-from</code>, <code>--exclude-from</code> and
<code>--filter-from</code> flags rules are processed from top to bottom
of the referenced file.</p>
<p>If there is an <code>--include</code> or <code>--include-from</code>
flag specified, rclone implies a <code>- **</code> rule which it adds to
the bottom of the internal rule list. Specifying a <code>+</code> rule
with a <code>--filter...</code> flag does not imply that rule.</p>
<p>Each path/file name passed through rclone is matched against the
combined filter list. At first match to a rule the path/file name is
included or excluded and no further filter rules are processed for that
path/file.</p>
<p>If rclone does not find a match, after testing against all rules
(including the implied rule if appropriate), the path/file name is
included.</p>
<p>Any path/file included at that stage is processed by the rclone
command.</p>
<p><code>--files-from</code> and <code>--files-from-raw</code> flags
over-ride and cannot be combined with other filter options.</p>
<p>To see the internal combined rule list, in regular expression form,
for a command add the <code>--dump filters</code> flag. Running an
rclone command with <code>--dump filters</code> and <code>-vv</code>
flags lists the internal filter elements and shows how they are applied
to each source path/file. There is not currently a means provided to
pass regular expression filter options into rclone directly though
character class filter rules contain character classes. <a
href="https://golang.org/pkg/regexp/syntax/">Go regular expression
reference</a></p>
<h3 id="directory_filter">How filter rules are applied to
directories</h3>
<p>Rclone commands are applied to path/file names not directories. The
entire contents of a directory can be matched to a filter by the pattern
<code>directory/*</code> or recursively by
<code>directory/**</code>.</p>
<p>Directory filter rules are defined with a closing <code>/</code>
separator.</p>
<p>E.g. <code>/directory/subdirectory/</code> is an rclone directory
filter rule.</p>
<p>Rclone commands can use directory filter rules to determine whether
they recurse into subdirectories. This potentially optimises access to a
remote by avoiding listing unnecessary directories. Whether optimisation
is desirable depends on the specific filter rules and source remote
content.</p>
<p>If any <a href="#regexp">regular expression filters</a> are in use,
then no directory recursion optimisation is possible, as rclone must
check every path against the supplied regular expression(s).</p>
<p>Directory recursion optimisation occurs if either:</p>
<ul>
<li><p>A source remote does not support the rclone <code>ListR</code>
primitive. local, sftp, Microsoft OneDrive and WebDAV do not support
<code>ListR</code>. Google Drive and most bucket type storage do. <a
href="https://rclone.org/overview/#optional-features">Full
list</a></p></li>
<li><p>On other remotes (those that support <code>ListR</code>), if the
rclone command is not naturally recursive, and provided it is not run
with the <code>--fast-list</code> flag. <code>ls</code>,
<code>lsf -R</code> and <code>size</code> are naturally recursive but
<code>sync</code>, <code>copy</code> and <code>move</code> are
not.</p></li>
<li><p>Whenever the <code>--disable ListR</code> flag is applied to an
rclone command.</p></li>
</ul>
<p>Rclone commands imply directory filter rules from path/file filter
rules. To view the directory filter rules rclone has implied for a
command specify the <code>--dump filters</code> flag.</p>
<p>E.g. for an include rule</p>
<pre class="text"><code>/a/*.jpg</code></pre>
<p>Rclone implies the directory include rule</p>
<pre class="text"><code>/a/</code></pre>
<p>Directory filter rules specified in an rclone command can limit the
scope of an rclone command but path/file filters still have to be
specified.</p>
<p>E.g. <code>rclone ls remote: --include /directory/</code> will not
match any files. Because it is an <code>--include</code> option the
<code>--exclude **</code> rule is implied, and the
<code>/directory/</code> pattern serves only to optimise access to the
remote by ignoring everything outside of that directory.</p>
<p>E.g. <code>rclone ls remote: --filter-from filter-list.txt</code>
with a file <code>filter-list.txt</code>:</p>
<pre class="text"><code>- /dir1/
- /dir2/
+ *.pdf
- **</code></pre>
<p>All files in directories <code>dir1</code> or <code>dir2</code> or
their subdirectories are completely excluded from the listing. Only
files of suffix <code>pdf</code> in the root of <code>remote:</code> or
its subdirectories are listed. The <code>- **</code> rule prevents
listing of any path/files not previously matched by the rules above.</p>
<p>Option <code>exclude-if-present</code> creates a directory exclude
rule based on the presence of a file in a directory and takes precedence
over other rclone directory filter rules.</p>
<p>When using pattern list syntax, if a pattern item contains either
<code>/</code> or <code>**</code>, then rclone will not able to imply a
directory filter rule from this pattern list.</p>
<p>E.g. for an include rule</p>
<pre class="text"><code>{dir1/**,dir2/**}</code></pre>
<p>Rclone will match files below directories <code>dir1</code> or
<code>dir2</code> only, but will not be able to use this filter to
exclude a directory <code>dir3</code> from being traversed.</p>
<p>Directory recursion optimisation may affect performance, but normally
not the result. One exception to this is sync operations with option
<code>--create-empty-src-dirs</code>, where any traversed empty
directories will be created. With the pattern list example
<code>{dir1/**,dir2/**}</code> above, this would create an empty
directory <code>dir3</code> on destination (when it exists on source).
Changing the filter to <code>{dir1,dir2}/**</code>, or splitting it into
two include rules <code>--include dir1/** --include dir2/**</code>, will
match the same files while also filtering directories, with the result
that an empty directory <code>dir3</code> will no longer be created.</p>
<h3 id="exclude---exclude-files-matching-pattern"><code>--exclude</code>
- Exclude files matching pattern</h3>
<p>Excludes path/file names from an rclone command based on a single
exclude rule.</p>
<p>This flag can be repeated. See above for the order filter flags are
processed in.</p>
<p><code>--exclude</code> should not be used with
<code>--include</code>, <code>--include-from</code>,
<code>--filter</code> or <code>--filter-from</code> flags.</p>
<p><code>--exclude</code> has no effect when combined with
<code>--files-from</code> or <code>--files-from-raw</code> flags.</p>
<p>E.g. <code>rclone ls remote: --exclude *.bak</code> excludes all .bak
files from listing.</p>
<p>E.g. <code>rclone size remote: --exclude "/dir/**"</code> returns the
total size of all files on <code>remote:</code> excluding those in root
directory <code>dir</code> and sub directories.</p>
<p>E.g. on Microsoft Windows
<code>rclone ls remote: --exclude "*\[{JP,KR,HK}\]*"</code> lists the
files in <code>remote:</code> without <code>[JP]</code> or
<code>[KR]</code> or <code>[HK]</code> in their name. Quotes prevent the
shell from interpreting the <code>\</code> characters.<code>\</code>
characters escape the <code>[</code> and <code>]</code> so an rclone
filter treats them literally rather than as a character-range. The
<code>{</code> and <code>}</code> define an rclone pattern list. For
other operating systems single quotes are required ie
<code>rclone ls remote: --exclude '*\[{JP,KR,HK}\]*'</code></p>
<h3
id="exclude-from---read-exclude-patterns-from-file"><code>--exclude-from</code>
- Read exclude patterns from file</h3>
<p>Excludes path/file names from an rclone command based on rules in a
named file. The file contains a list of remarks and pattern rules.</p>
<p>For an example <code>exclude-file.txt</code>:</p>
<pre class="text"><code># a sample exclude rule file
*.bak
file2.jpg</code></pre>
<p><code>rclone ls remote: --exclude-from exclude-file.txt</code> lists
the files on <code>remote:</code> except those named
<code>file2.jpg</code> or with a suffix <code>.bak</code>. That is
equivalent to
<code>rclone ls remote: --exclude file2.jpg --exclude "*.bak"</code>.</p>
<p>This flag can be repeated. See above for the order filter flags are
processed in.</p>
<p>The <code>--exclude-from</code> flag is useful where multiple exclude
filter rules are applied to an rclone command.</p>
<p><code>--exclude-from</code> should not be used with
<code>--include</code>, <code>--include-from</code>,
<code>--filter</code> or <code>--filter-from</code> flags.</p>
<p><code>--exclude-from</code> has no effect when combined with
<code>--files-from</code> or <code>--files-from-raw</code> flags.</p>
<p><code>--exclude-from</code> followed by <code>-</code> reads filter
rules from standard input.</p>
<h3 id="include---include-files-matching-pattern"><code>--include</code>
- Include files matching pattern</h3>
<p>Adds a single include rule based on path/file names to an rclone
command.</p>
<p>This flag can be repeated. See above for the order filter flags are
processed in.</p>
<p><code>--include</code> has no effect when combined with
<code>--files-from</code> or <code>--files-from-raw</code> flags.</p>
<p><code>--include</code> implies <code>--exclude **</code> at the end
of an rclone internal filter list. Therefore if you mix
<code>--include</code> and <code>--include-from</code> flags with
<code>--exclude</code>, <code>--exclude-from</code>,
<code>--filter</code> or <code>--filter-from</code>, you must use
include rules for all the files you want in the include statement. For
more flexibility use the <code>--filter-from</code> flag.</p>
<p>E.g. <code>rclone ls remote: --include "*.{png,jpg}"</code> lists the
files on <code>remote:</code> with suffix <code>.png</code> and
<code>.jpg</code>. All other files are excluded.</p>
<p>E.g. multiple rclone copy commands can be combined with
<code>--include</code> and a pattern-list.</p>
<pre class="console"><code>rclone copy /vol1/A remote:A
rclone copy /vol1/B remote:B</code></pre>
<p>is equivalent to:</p>
<pre class="console"><code>rclone copy /vol1 remote: --include &quot;{A,B}/**&quot;</code></pre>
<p>E.g. <code>rclone ls remote:/wheat --include "??[^[:punct:]]*"</code>
lists the files <code>remote:</code> directory <code>wheat</code> (and
subdirectories) whose third character is not punctuation. This example
uses an <a href="https://golang.org/pkg/regexp/syntax/">ASCII character
class</a>.</p>
<h3
id="include-from---read-include-patterns-from-file"><code>--include-from</code>
- Read include patterns from file</h3>
<p>Adds path/file names to an rclone command based on rules in a named
file. The file contains a list of remarks and pattern rules.</p>
<p>For an example <code>include-file.txt</code>:</p>
<pre class="text"><code># a sample include rule file
*.jpg
file2.avi</code></pre>
<p><code>rclone ls remote: --include-from include-file.txt</code> lists
the files on <code>remote:</code> with name <code>file2.avi</code> or
suffix <code>.jpg</code>. That is equivalent to
<code>rclone ls remote: --include file2.avi --include "*.jpg"</code>.</p>
<p>This flag can be repeated. See above for the order filter flags are
processed in.</p>
<p>The <code>--include-from</code> flag is useful where multiple include
filter rules are applied to an rclone command.</p>
<p><code>--include-from</code> implies <code>--exclude **</code> at the
end of an rclone internal filter list. Therefore if you mix
<code>--include</code> and <code>--include-from</code> flags with
<code>--exclude</code>, <code>--exclude-from</code>,
<code>--filter</code> or <code>--filter-from</code>, you must use
include rules for all the files you want in the include statement. For
more flexibility use the <code>--filter-from</code> flag.</p>
<p><code>--include-from</code> has no effect when combined with
<code>--files-from</code> or <code>--files-from-raw</code> flags.</p>
<p><code>--include-from</code> followed by <code>-</code> reads filter
rules from standard input.</p>
<h3 id="filter---add-a-file-filtering-rule"><code>--filter</code> - Add
a file-filtering rule</h3>
<p>Specifies path/file names to an rclone command, based on a single
include or exclude rule, in <code>+</code> or <code>-</code> format.</p>
<p>This flag can be repeated. See above for the order filter flags are
processed in.</p>
<p><code>--filter +</code> differs from <code>--include</code>. In the
case of <code>--include</code> rclone implies an
<code>--exclude *</code> rule which it adds to the bottom of the
internal rule list. <code>--filter...+</code> does not imply that
rule.</p>
<p><code>--filter</code> has no effect when combined with
<code>--files-from</code> or <code>--files-from-raw</code> flags.</p>
<p><code>--filter</code> should not be used with <code>--include</code>,
<code>--include-from</code>, <code>--exclude</code> or
<code>--exclude-from</code> flags.</p>
<p>E.g. <code>rclone ls remote: --filter "- *.bak"</code> excludes all
<code>.bak</code> files from a list of <code>remote:</code>.</p>
<h3
id="filter-from---read-filtering-patterns-from-a-file"><code>--filter-from</code>
- Read filtering patterns from a file</h3>
<p>Adds path/file names to an rclone command based on rules in a named
file. The file contains a list of remarks and pattern rules. Include
<!-- markdownlint-disable-next-line no-space-in-code --> rules start
with <code>+</code> and exclude rules with <code>-</code>.
<code>!</code> clears existing rules. Rules are processed in the order

<p>Arrange the order of filter rules with the most restrictive first and
work down.</p>
<p>Lines starting with # or ; are ignored, and can be used to write

<p><code>rclone ls remote: --filter-from filter-file.txt</code> lists
the path/files on <code>remote:</code> including all <code>jpg</code>

files without the suffix <code>.jpg</code> or <code>.png</code> are
excluded.</p>
<p>E.g. for an alternative <code>filter-file.txt</code>:</p>
<pre class="text"><code>+ *.jpg
+ *.gif
!
+ 42.doc
- *</code></pre>
<p>Only file 42.doc is listed. Prior rules are cleared by the
<code>!</code>.</p>
<h3
id="files-from---read-list-of-source-file-names"><code>--files-from</code>
- Read list of source-file names</h3>
<p>Adds path/files to an rclone command from a list in a named file.
Rclone processes the path/file names in the order of the list, and no
others.</p>
<p>Other filter flags (<code>--include</code>,
<code>--include-from</code>, <code>--exclude</code>,
<code>--exclude-from</code>, <code>--filter</code> and
<code>--filter-from</code>) are ignored when <code>--files-from</code>
is used.</p>
<p><code>--files-from</code> expects a list of files as its input.
Leading or trailing whitespace is stripped from the input lines. Lines
starting with <code>#</code> or <code>;</code> are ignored.</p>
<p><code>--files-from</code> followed by <code>-</code> reads the list
of files from standard input.</p>
<p>Rclone commands with a <code>--files-from</code> flag traverse the
remote, treating the names in <code>--files-from</code> as a set of
filters.</p>
<p>If the <code>--no-traverse</code> and <code>--files-from</code> flags
are used together an rclone command does not traverse the remote.
Instead it addresses each path/file named in the file individually. For
each path/file name, that requires typically 1 API call. This can be
efficient for a short <code>--files-from</code> list and a remote
containing many files.</p>
<p>Rclone commands do not error if any names in the
<code>--files-from</code> file are missing from the source remote.</p>
<p>The <code>--files-from</code> flag can be repeated in a single rclone
command to read path/file names from more than one file. The files are
read from left to right along the command line.</p>
<p>Paths within the <code>--files-from</code> file are interpreted as
starting with the root specified in the rclone command. Leading
<code>/</code> separators are ignored. See <a
href="#files-from-raw-read-list-of-source-file-names-without-any-processing">--files-from-raw</a>
if you need the input to be processed in a raw manner.</p>
<p>E.g. for a file <code>files-from.txt</code>:</p>
<pre class="text"><code># comment
file1.jpg
subdir/file2.jpg</code></pre>
<p><code>rclone copy --files-from files-from.txt /home/me/pics remote:pics</code>
copies the following, if they exist, and only those files.</p>
<pre class="text"><code>/home/me/pics/file1.jpg        → remote:pics/file1.jpg
/home/me/pics/subdir/file2.jpg → remote:pics/subdir/file2.jpg</code></pre>
<p>E.g. to copy the following files referenced by their absolute
paths:</p>
<pre class="text"><code>/home/user1/42
/home/user1/dir/ford
/home/user2/prefect</code></pre>
<p>First find a common subdirectory - in this case <code>/home</code>
and put the remaining files in <code>files-from.txt</code> with or
without leading <code>/</code>, e.g.</p>
<pre class="text"><code>user1/42
user1/dir/ford
user2/prefect</code></pre>
<p>Then copy these to a remote:</p>
<pre class="console"><code>rclone copy --files-from files-from.txt /home remote:backup</code></pre>
<p>The three files are transferred as follows:</p>
<pre class="text"><code>/home/user1/42       → remote:backup/user1/important
/home/user1/dir/ford → remote:backup/user1/dir/file
/home/user2/prefect  → remote:backup/user2/stuff</code></pre>
<p>Alternatively if <code>/</code> is chosen as root
<code>files-from.txt</code> will be:</p>
<pre class="text"><code>/home/user1/42
/home/user1/dir/ford
/home/user2/prefect</code></pre>
<p>The copy command will be:</p>
<pre class="console"><code>rclone copy --files-from files-from.txt / remote:backup</code></pre>
<p>Then there will be an extra <code>home</code> directory on the
remote:</p>
<pre class="text"><code>/home/user1/42       → remote:backup/home/user1/42
/home/user1/dir/ford → remote:backup/home/user1/dir/ford
/home/user2/prefect  → remote:backup/home/user2/prefect</code></pre>
<h3
id="files-from-raw---read-list-of-source-file-names-without-any-processing"><code>--files-from-raw</code>
- Read list of source-file names without any processing</h3>
<p>This flag is the same as <code>--files-from</code> except that input
is read in a raw manner. Lines with leading / trailing whitespace, and
lines starting with <code>;</code> or <code>#</code> are read without
any processing. <a href="https://rclone.org/commands/rclone_lsf/">rclone
lsf</a> has a compatible format that can be used to export file lists
from remotes for input to <code>--files-from-raw</code>.</p>
<h3
id="ignore-case---make-searches-case-insensitive"><code>--ignore-case</code>
- make searches case insensitive</h3>
<p>By default, rclone filter patterns are case sensitive. The
<code>--ignore-case</code> flag makes all of the filters patterns on the
command line case insensitive.</p>
<p>E.g. <code>--include "zaphod.txt"</code> does not match a file
<code>Zaphod.txt</code>. With <code>--ignore-case</code> a match is
made.</p>
<h2 id="quoting-shell-metacharacters">Quoting shell metacharacters</h2>
<p>Rclone commands with filter patterns containing shell metacharacters
may not as work as expected in your shell and may require quoting.</p>
<p>E.g. linux, OSX (<code>*</code> metacharacter)</p>
<ul>
<li><code>--include \*.jpg</code></li>
<li><code>--include '*.jpg'</code></li>
<li><code>--include='*.jpg'</code></li>
</ul>
<p>Microsoft Windows expansion is done by the command, not shell, so
<code>--include *.jpg</code> does not require quoting.</p>
<p>If the rclone error
<code>Command .... needs .... arguments maximum: you provided .... non flag arguments:</code>
is encountered, the cause is commonly spaces within the name of a remote
or flag value. The fix then is to quote values containing spaces.</p>
<h2 id="other-filters">Other filters</h2>
<h3
id="min-size---dont-transfer-any-file-smaller-than-this"><code>--min-size</code>
- Don't transfer any file smaller than this</h3>
<p>Controls the minimum size file within the scope of an rclone command.
Default units are <code>KiB</code> but abbreviations <code>B</code>,
<code>K</code>, <code>M</code>, <code>G</code>, <code>T</code> or
<code>P</code> are valid.</p>
<p>E.g. <code>rclone ls remote: --min-size 50k</code> lists files on
<code>remote:</code> of 50 KiB size or larger.</p>
<p>See <a href="https://rclone.org/docs/#size-options">the size option
docs</a> for more info.</p>
<h3
id="max-size---dont-transfer-any-file-larger-than-this"><code>--max-size</code>
- Don't transfer any file larger than this</h3>
<p>Controls the maximum size file within the scope of an rclone command.
Default units are <code>KiB</code> but abbreviations <code>B</code>,
<code>K</code>, <code>M</code>, <code>G</code>, <code>T</code> or
<code>P</code> are valid.</p>
<p>E.g. <code>rclone ls remote: --max-size 1G</code> lists files on
<code>remote:</code> of 1 GiB size or smaller.</p>
<p>See <a href="https://rclone.org/docs/#size-options">the size option
docs</a> for more info.</p>
<h3
id="max-age---dont-transfer-any-file-older-than-this"><code>--max-age</code>
- Don't transfer any file older than this</h3>
<p>Controls the maximum age of files within the scope of an rclone
command.</p>
<p><code>--max-age</code> applies only to files and not to
directories.</p>
<p>E.g. <code>rclone ls remote: --max-age 2d</code> lists files on
<code>remote:</code> of 2 days old or less.</p>
<p>See <a href="https://rclone.org/docs/#time-options">the time option
docs</a> for valid formats.</p>
<h3
id="min-age---dont-transfer-any-file-younger-than-this"><code>--min-age</code>
- Don't transfer any file younger than this</h3>
<p>Controls the minimum age of files within the scope of an rclone
command. (see <code>--max-age</code> for valid formats)</p>
<p><code>--min-age</code> applies only to files and not to
directories.</p>
<p>E.g. <code>rclone ls remote: --min-age 2d</code> lists files on
<code>remote:</code> of 2 days old or more.</p>
<p>See <a href="https://rclone.org/docs/#time-options">the time option
docs</a> for valid formats.</p>
<h3 id="hash-filter"><code>--hash-filter</code> - Deterministically
select a subset of files</h3>
<p>The <code>--hash-filter</code> flag enables selecting a deterministic
subset of files, useful for:</p>
<ol type="1">
<li>Running large sync operations across multiple machines.</li>
<li>Checking a subset of files for bitrot.</li>
<li>Any other operations where a sample of files is required.</li>
</ol>
<h4 id="syntax">Syntax</h4>
<p>The flag takes two parameters expressed as a fraction:</p>
<pre class="text"><code>--hash-filter K/N</code></pre>
<ul>
<li><code>N</code>: The total number of partitions (must be a positive
integer).</li>
<li><code>K</code>: The specific partition to select (an integer from
<code>0</code> to <code>N</code>).</li>
</ul>
<p>For example:</p>
<ul>
<li><code>--hash-filter 1/3</code>: Selects the first third of the
files.</li>
<li><code>--hash-filter 2/3</code> and <code>--hash-filter 3/3</code>:
Select the second and third partitions, respectively.</li>
</ul>
<p>Each partition is non-overlapping, ensuring all files are covered
without duplication.</p>
<h4 id="random-partition-selection">Random Partition Selection</h4>
<p>Use <code>@</code> as <code>K</code> to randomly select a
partition:</p>
<pre class="text"><code>--hash-filter @/M</code></pre>
<p>For example, <code>--hash-filter @/3</code> will randomly select a
number between 0 and 2. This will stay constant across retries.</p>
<h4 id="how-it-works">How It Works</h4>
<ul>
<li>Rclone takes each file's full path, normalizes it to lowercase, and
applies Unicode normalization.</li>
<li>It then hashes the normalized path into a 64 bit number.</li>
<li>The hash result is reduced modulo <code>N</code> to assign the file
to a partition.</li>
<li>If the calculated partition does not match <code>K</code> the file
is excluded.</li>
<li>Other filters may apply if the file is not excluded.</li>
</ul>
<p><strong>Important:</strong> Rclone will traverse all directories to
apply the filter.</p>
<h4 id="usage-notes">Usage Notes</h4>
<ul>
<li>Safe to use with <code>rclone sync</code>; source and destination
selections will match.</li>
<li><strong>Do not</strong> use with <code>--delete-excluded</code>, as
this could delete unselected files.</li>
<li>Ignored if <code>--files-from</code> is used.</li>
</ul>
<h4 id="examples-1">Examples</h4>
<h5 id="dividing-files-into-4-partitions">Dividing files into 4
partitions</h5>
<p>Assuming the current directory contains <code>file1.jpg</code>
through <code>file9.jpg</code>:</p>
<pre class="console"><code>$ rclone lsf --hash-filter 0/4 .
file1.jpg
file5.jpg

$ rclone lsf --hash-filter 1/4 .
file3.jpg
file6.jpg
file9.jpg

$ rclone lsf --hash-filter 2/4 .
file2.jpg
file4.jpg

$ rclone lsf --hash-filter 3/4 .

<pre class="console"><code>rclone check --download --hash-filter @/100 source:path destination:path</code></pre>
<h2 id="other-flags">Other flags</h2>
<h3
id="delete-excluded---delete-files-on-dest-excluded-from-sync"><code>--delete-excluded</code>
- Delete files on dest excluded from sync</h3>
<p><strong>Important</strong> this flag is dangerous to your data - use
with <code>--dry-run</code> and <code>-v</code> first.</p>
<p>In conjunction with <code>rclone sync</code>,
<code>--delete-excluded</code> deletes any files on the destination
which are excluded from the command.</p>
<p>E.g. the scope of <code>rclone sync --interactive A: B:</code> can be
restricted:</p>
<pre class="console"><code>rclone --min-size 50k --delete-excluded sync A: B:</code></pre>
<p>All files on <code>B:</code> which are less than 50 KiB are deleted
because they are excluded from the rclone sync command.</p>
<h3
id="dump-filters---dump-the-filters-to-the-output"><code>--dump filters</code>
- dump the filters to the output</h3>
<p>Dumps the defined filters to standard output in regular expression
format.</p>
<p>Useful for debugging.</p>
<h2 id="exclude-directory-based-on-a-file">Exclude directory based on a
file</h2>
<p>The <code>--exclude-if-present</code> flag controls whether a
directory is within the scope of an rclone command based on the presence
of a named file within it. The flag can be repeated to check for
multiple file names, presence of any of them will exclude the
directory.</p>
<p>This flag has a priority over other filter flags.</p>
<p>E.g. for the following directory structure:</p>
<pre class="text"><code>dir1/file1
dir1/dir2/file2
dir1/dir2/dir3/file3
dir1/dir2/dir3/.ignore</code></pre>
<p>The command <code>rclone ls --exclude-if-present .ignore dir1</code>
does not list <code>dir3</code>, <code>file3</code> or
<code>.ignore</code>.</p>
<h2 id="metadata">Metadata filters</h2>
<p>The metadata filters work in a very similar way to the normal file
name filters, except they match <a
href="https://rclone.org/docs/#metadata">metadata</a> on the object.</p>
<p>The metadata should be specified as <code>key=value</code> patterns.
This may be wildcarded using the normal <a href="#patterns">filter
patterns</a> or <a href="#regexp">regular expressions</a>.</p>
<p>For example if you wished to list only local files with a mode of
<code>100664</code> you could do that with:</p>
<pre class="console"><code>rclone lsf -M --files-only --metadata-include &quot;mode=100664&quot; .</code></pre>
<p>Or if you wished to show files with an <code>atime</code>,
<code>mtime</code> or <code>btime</code> at a given date:</p>
<pre class="console"><code>rclone lsf -M --files-only --metadata-include &quot;[abm]time=2022-12-16*&quot; .</code></pre>
<p>Like file filtering, metadata filtering only applies to files not to
directories.</p>
<p>The filters can be applied using these flags.</p>
<ul>
<li><code>--metadata-include</code> - Include metadatas matching
pattern</li>
<li><code>--metadata-include-from</code> - Read metadata include
patterns from file (use - to read from stdin)</li>
<li><code>--metadata-exclude</code> - Exclude metadatas matching
pattern</li>
<li><code>--metadata-exclude-from</code> - Read metadata exclude
patterns from file (use - to read from stdin)</li>
<li><code>--metadata-filter</code> - Add a metadata filtering rule</li>
<li><code>--metadata-filter-from</code> - Read metadata filtering
patterns from a file (use - to read from stdin)</li>
</ul>
<p>Each flag can be repeated. See the section on <a
href="#how-filter-rules-work">how filter rules are applied</a> for more
details - these flags work in an identical way to the file name
filtering flags, but instead of file name patterns have metadata
patterns.</p>
<h2 id="common-pitfalls">Common pitfalls</h2>
<p>The most frequent filter support issues on the <a
href="https://forum.rclone.org/">rclone forum</a> are:</p>
<ul>
<li>Not using paths relative to the root of the remote</li>
<li>Not using <code>/</code> to match from the root of a remote</li>
<li>Not using <code>**</code> to match the contents of a directory</li>
</ul>
<h1 id="gui-experimental">GUI (Experimental)</h1>
<p>Rclone can serve a web based GUI (graphical user interface). This is
somewhat experimental at the moment so things may be subject to
change.</p>
<p>Run this command in a terminal and rclone will download and then
display the GUI in a web browser.</p>
<pre class="console"><code>rclone rcd --rc-web-gui</code></pre>
<p>This will produce logs like this and rclone needs to continue to run
to serve the GUI:</p>
<pre class="text"><code>2019/08/25 11:40:14 NOTICE: A new release for gui is present at https://github.com/rclone/rclone-webui-react/releases/download/v0.0.6/currentbuild.zip
2019/08/25 11:40:14 NOTICE: Downloading webgui binary. Please wait. [Size: 3813937, Path :  /home/USER/.cache/rclone/webgui/v0.0.6.zip]

2019/08/25 11:40:16 NOTICE: Serving remote control on http://127.0.0.1:5572/</code></pre>
<p>This assumes you are running rclone locally on your machine. It is
possible to separate the rclone and the GUI - see below for details.</p>
<p>If you wish to check for updates then you can add
<code>--rc-web-gui-update</code> to the command line.</p>
<p>If you find your GUI broken, you may force it to update by add
<code>--rc-web-gui-force-update</code>.</p>
<p>By default, rclone will open your browser. Add
<code>--rc-web-gui-no-open-browser</code> to disable this feature.</p>
<h2 id="using-the-gui">Using the GUI</h2>
<p>Once the GUI opens, you will be looking at the dashboard which has an
overall overview.</p>
<p>On the left hand side you will see a series of view buttons you can
click on:</p>
<ul>
<li>Dashboard - main overview</li>
<li>Configs - examine and create new configurations</li>
<li>Explorer - view, download and upload files to the cloud storage
systems</li>
<li>Backend - view or alter the backend config</li>
<li>Log out</li>
</ul>
<p>(More docs and walkthrough video to come!)</p>
<h2 id="how-it-works-1">How it works</h2>
<p>When you run the <code>rclone rcd --rc-web-gui</code> this is what
happens</p>
<ul>
<li>Rclone starts but only runs the remote control API ("rc").</li>
<li>The API is bound to localhost with an auto-generated username and
password.</li>
<li>If the API bundle is missing then rclone will download it.</li>
<li>rclone will start serving the files from the API bundle over the
same port as the API</li>
<li>rclone will open the browser with a <code>login_token</code> so it
can log straight in.</li>
</ul>
<h2 id="advanced-use">Advanced use</h2>
<p>The <code>rclone rcd</code> may use any of the <a
href="https://rclone.org/rc/#supported-parameters">flags documented on
the rc page</a>.</p>
<p>The flag <code>--rc-web-gui</code> is shorthand for</p>
<ul>
<li>Download the web GUI if necessary</li>
<li>Check we are using some authentication</li>
<li><code>--rc-user gui</code></li>
<li><code>--rc-pass &lt;random password&gt;</code></li>
<li><code>--rc-serve</code></li>
</ul>
<p>These flags can be overridden as desired.</p>

rcd documentation</a>.</p>
<h3 id="example-running-a-public-gui">Example: Running a public GUI</h3>
<p>For example the GUI could be served on a public port over SSL using
an htpasswd file using the following flags:</p>
<ul>
<li><code>--rc-web-gui</code></li>
<li><code>--rc-addr :443</code></li>
<li><code>--rc-htpasswd /path/to/htpasswd</code></li>

<li><code>--rc-web-gui</code></li>
<li><code>--rc-baseurl rclone</code></li>
<li><code>--rc-htpasswd /path/to/htpasswd</code></li>
</ul>
<p>Or instead of htpasswd if you just want a single user and

<li><code>--rc-user me</code></li>
<li><code>--rc-pass mypassword</code></li>
</ul>

<p>By default rclone will require authorisation to have been set up on
the rc interface in order to use any methods which access any rclone
remotes. Eg <code>operations/list</code> is denied as it involved
creating a remote as is <code>sync/copy</code>.</p>
<p>If this is set then no authorisation will be required on the server
to use these methods. The alternative is to use <code>--rc-user</code>
and <code>--rc-pass</code> and use these credentials in the request.</p>
<p>Default Off.</p>
<h3 id="rc-baseurl">--rc-baseurl</h3>
<p>Prefix for URLs.</p>

<p>User-specified template.</p>
<h2 id="api-rc">Accessing the remote control via the rclone rc
command</h2>
<p>Rclone itself implements the remote control protocol in its
<code>rclone rc</code> command.</p>
<p>You can use it like this:</p>
<pre class="console"><code>$ rclone rc rc/noop param1=one param2=two
{
    &quot;param1&quot;: &quot;one&quot;,
    &quot;param2&quot;: &quot;two&quot;
}</code></pre>
<p>If the remote is running on a different URL than the default
<code>http://localhost:5572/</code>, use the <code>--url</code> option
to specify it:</p>
<pre class="console"><code>rclone rc --url http://some.remote:1234/ rc/noop</code></pre>
<p>Or, if the remote is listening on a Unix socket, use the
<code>--unix-socket</code> option instead:</p>
<pre class="console"><code>rclone rc --unix-socket /tmp/rclone.sock rc/noop</code></pre>
<p>Run <code>rclone rc</code> on its own, without any commands, to see
the help for the installed remote control commands. Note that this also
needs to connect to the remote server.</p>
<h2 id="json-input">JSON input</h2>
<p><code>rclone rc</code> also supports a <code>--json</code> flag which
can be used to send more complicated input parameters.</p>
<pre class="console"><code>$ rclone rc --json &#39;{ &quot;p1&quot;: [1,&quot;2&quot;,null,4], &quot;p2&quot;: { &quot;a&quot;:1, &quot;b&quot;:2 } }&#39; rc/noop
{
    &quot;p1&quot;: [
        1,
        &quot;2&quot;,
        null,
        4
    ],
    &quot;p2&quot;: {
        &quot;a&quot;: 1,
        &quot;b&quot;: 2
    }
}</code></pre>
<p>If the parameter being passed is an object then it can be passed as a
JSON string rather than using the <code>--json</code> flag which
simplifies the command line.</p>
<pre class="console"><code>rclone rc operations/list fs=/tmp remote=test opt=&#39;{&quot;showHash&quot;: true}&#39;</code></pre>
<p>Rather than</p>
<pre class="console"><code>rclone rc operations/list --json &#39;{&quot;fs&quot;: &quot;/tmp&quot;, &quot;remote&quot;: &quot;test&quot;, &quot;opt&quot;: {&quot;showHash&quot;: true}}&#39;</code></pre>
<h2 id="special-parameters">Special parameters</h2>
<p>The rc interface supports some special parameters which apply to
<strong>all</strong> commands. These start with <code>_</code> to show
they are different.</p>
<h3 id="running-asynchronous-jobs-with-_async-true">Running asynchronous
jobs with _async = true</h3>
<p>Each rc call is classified as a job and it is assigned its own id. By
default jobs are executed immediately as they are created or
synchronously.</p>
<p>If <code>_async</code> has a true value when supplied to an rc call
then it will return immediately with a job id and execute id, and the
task will be run in the background. The <code>job/status</code> call can
be used to get information of the background job. The job can be queried
for up to 1 minute after it has finished.</p>
<p>It is recommended that potentially long running jobs, e.g.
<code>sync/sync</code>, <code>sync/copy</code>, <code>sync/move</code>,
<code>operations/purge</code> are run with the <code>_async</code> flag
to avoid any potential problems with the HTTP request and response
timing out.</p>
<p>Starting a job with the <code>_async</code> flag:</p>
<pre class="console"><code>$ rclone rc --json &#39;{ &quot;p1&quot;: [1,&quot;2&quot;,null,4], &quot;p2&quot;: { &quot;a&quot;:1, &quot;b&quot;:2 }, &quot;_async&quot;: true }&#39; rc/noop
{
    &quot;jobid&quot;: 2,
    &quot;executeId&quot;: &quot;d794c33c-463e-4acf-b911-f4b23e4f40b7&quot;
}</code></pre>
<p>The <code>jobid</code> is a unique identifier for the job within this
rclone instance. The <code>executeId</code> identifies the rclone
process instance and changes after rclone restart. Together, the pair
(<code>executeId</code>, <code>jobid</code>) uniquely identifies a job
across rclone restarts.</p>
<p>Query the status to see if the job has finished. For more information
on the meaning of these return parameters see the
<code>job/status</code> call.</p>
<pre class="console"><code>$ rclone rc --json &#39;{ &quot;jobid&quot;:2 }&#39; job/status
{
    &quot;duration&quot;: 0.000124163,

        ],
        &quot;p2&quot;: {
            &quot;a&quot;: 1,
            &quot;b&quot;: 2
        }
    },

    &quot;success&quot;: true
}</code></pre>
<p><code>job/list</code> can be used to show running or recently
completed jobs along with their status</p>
<pre class="console"><code>$ rclone rc job/list
{
    &quot;executeId&quot;: &quot;d794c33c-463e-4acf-b911-f4b23e4f40b7&quot;,

        2
    ],
    &quot;running_ids&quot;: [
        2
    ]
}</code></pre>
<p>This shows: - <code>executeId</code> - the current rclone instance ID
(same for all jobs, changes after restart) - <code>jobids</code> - array
of all job IDs (both running and finished) - <code>running_ids</code> -
array of currently running job IDs - <code>finished_ids</code> - array
of finished job IDs</p>
<h3 id="setting-config-flags-with-_config">Setting config flags with
_config</h3>
<p>If you wish to set config (the equivalent of the global flags) for
the duration of an rc call only then pass in the <code>_config</code>

<p>This should be in the same format as the <code>main</code> key
returned by <a href="#options-get">options/get</a>.</p>
<pre class="console"><code>rclone rc --loopback options/get blocks=main</code></pre>

<h3 id="assigning-operations-to-groups-with-_group-value">Assigning
operations to groups with _group = value</h3>
<p>Each rc call has its own stats group for tracking its metrics. By
default grouping is done by the composite group name from prefix
<code>job/</code> and id of the job like so <code>job/1</code>.</p>
<p>If <code>_group</code> has a value then stats for that request will
be grouped under that value. This allows caller to group stats under
their own name.</p>
<p>Stats for specific group can be accessed by passing
<code>group</code> to <code>core/stats</code>:</p>

<h2 id="data-types">Data types</h2>
<p>When the API returns types, these will mostly be straight forward
integer, string or boolean types.</p>
<p>However some of the types returned by the <a
href="#options-get">options/get</a> call and taken by the <a
href="#options-set">options/set</a> calls as well as the
<code>vfsOpt</code>, <code>mountOpt</code> and the <code>_config</code>
parameters.</p>
<ul>
<li><code>Duration</code> - these are returned as an integer duration in
nanoseconds. They may be set as an integer, or they may be set with time
string, eg "5s". See the <a
href="https://rclone.org/docs/#options">options section</a> for more
info.</li>
<li><code>Size</code> - these are returned as an integer number of
bytes. They may be set as an integer or they may be set with a size
suffix string, eg "10M". See the <a
href="https://rclone.org/docs/#options">options section</a> for more
info.</li>
<li>Enumerated type (such as <code>CutoffMode</code>,
<code>DumpFlags</code>, <code>LogLevel</code>, <code>VfsCacheMode</code>
- these will be returned as an integer and may be set as an integer but
more conveniently they can be set as a string, eg "HARD" for
<code>CutoffMode</code> or <code>DEBUG</code> for
<code>LogLevel</code>.</li>
<li><code>BandwidthSpec</code> - this will be set and returned as a

<h3 id="option-blocks">Option blocks</h3>
<p>The calls <a href="#options-info">options/info</a> (for the main

is the sentence shown when running <code>rclone help flags</code>.</p>
<h2 id="specifying-remotes-to-work-on">Specifying remotes to work
on</h2>
<p>Remotes are specified with the <code>fs=</code>, <code>srcFs=</code>,
<code>dstFs=</code> parameters depending on the command being used.</p>
<p>The parameters can be a string as per the rest of rclone, eg
<code>s3:bucket/path</code> or <code>:sftp:/my/dir</code>. They can also
be specified as JSON blobs.</p>
<p>If specifying a JSON blob it should be a object mapping strings to
strings. These values will be used to configure the remote. There are 3
special values which may be set:</p>
<ul>
<li><code>type</code> - set to <code>type</code> to specify a remote
called <code>:type:</code></li>
<li><code>_name</code> - set to <code>name</code> to specify a remote
called <code>name:</code></li>
<li><code>_root</code> - sets the root of the remote - may be empty</li>
</ul>
<p>One of <code>_name</code> or <code>type</code> should normally be
set. If the <code>local</code> backend is desired then <code>type</code>
should be set to <code>local</code>. If <code>_root</code> isn't
specified then it defaults to the root of the remote.</p>
<p>For example this JSON is equivalent to <code>remote:/tmp</code></p>

<li>fs - a remote name string e.g. "drive:"</li>
<li>arg - a list of arguments for the backend command</li>
<li>opt - a map of string to string of options</li>
</ul>
<p>Returns:</p>
<ul>
<li>result - result from the backend command</li>
</ul>
<p>Example:</p>
<pre><code>rclone rc backend/command command=noop fs=. -o echo=yes -o blue -a path1 -a path2</code></pre>
<p>Returns</p>
<pre><code>{
    &quot;result&quot;: {
        &quot;arg&quot;: [
            &quot;path1&quot;,
            &quot;path2&quot;
        ],
        &quot;name&quot;: &quot;noop&quot;,
        &quot;opt&quot;: {
            &quot;blue&quot;: &quot;&quot;,
            &quot;echo&quot;: &quot;yes&quot;
        }
    }
}</code></pre>
<p>Note that this is the direct equivalent of using this "backend"
command:</p>
<pre><code>rclone backend noop . -o echo=yes -o blue path1 path2</code></pre>
<p>Note that arguments must be preceded by the "-a" flag</p>
<p>See the <a

<h3 id="cache-expire">cache/expire: Purge a remote from cache</h3>
<p>Purge a remote from the cache backend. Supports either a directory or
a file. Params: - remote = path to remote (required) - withData =
true/false to delete cached data (chunks) as well (optional)</p>
<p>Eg</p>

rclone rc cache/expire remote=/ withData=true</code></pre>
<h3 id="cache-fetch">cache/fetch: Fetch file chunks</h3>
<p>Ensure the specified file chunks are cached on disk.</p>
<p>The chunks= parameter specifies the file chunks to check. It takes a
comma separated list of array slice indices. The slice indices are
similar to Python slices: start[:end]</p>
<p>start is the 0 based chunk number from the beginning of the file to
fetch inclusive. end is 0 based chunk number from the beginning of the
file to fetch exclusive. Both values can be negative, in which case they
count from the back of the file. The value "-5:" represents the last 5
chunks of a file.</p>
<p>Some valid examples are: ":5,-5:" -&gt; the first and last five
chunks "0,-2" -&gt; the first and the second last chunk "0:10" -&gt; the
first ten chunks</p>
<p>Any parameter with a key that starts with "file" can be used to
specify files to fetch, e.g.</p>
<pre><code>rclone rc cache/fetch chunks=0 file=hello file2=home/goodbye</code></pre>

<h3 id="debug-set-block-profile-rate">debug/set-block-profile-rate: Set
runtime.SetBlockProfileRate for blocking profiling.</h3>
<p>SetBlockProfileRate controls the fraction of goroutine blocking
events that are reported in the blocking profile. The profiler aims to
sample an average of one blocking event per rate nanoseconds spent
blocked.</p>
<p>To include every blocking event in the profile, pass rate = 1. To
turn off profiling entirely, pass rate &lt;= 0.</p>
<p>After calling this you can use this to see the blocking profile:</p>
<pre><code>go tool pprof http://localhost:5572/debug/pprof/block</code></pre>
<p>Parameters:</p>
<ul>
<li>rate - int</li>
</ul>
<h3 id="debug-set-gc-percent">debug/set-gc-percent: Call
runtime/debug.SetGCPercent for setting the garbage collection target
percentage.</h3>
<p>SetGCPercent sets the garbage collection target percentage: a
collection is triggered when the ratio of freshly allocated data to live
data remaining after the previous collection reaches this percentage.
SetGCPercent returns the previous setting. The initial setting is the
value of the GOGC environment variable at startup, or 100 if the
variable is not set.</p>
<p>This setting may be effectively reduced in order to maintain a memory
limit. A negative percentage effectively disables garbage collection,
unless the memory limit is reached.</p>
<p>See https://pkg.go.dev/runtime/debug#SetMemoryLimit for more
details.</p>
<p>Parameters:</p>
<ul>
<li>gc-percent - int</li>
</ul>
<h3
id="debug-set-mutex-profile-fraction">debug/set-mutex-profile-fraction:
Set runtime.SetMutexProfileFraction for mutex profiling.</h3>
<p>SetMutexProfileFraction controls the fraction of mutex contention
events that are reported in the mutex profile. On average 1/rate events
are reported. The previous rate is returned.</p>
<p>To turn off profiling entirely, pass rate 0. To just read the current
rate, pass rate &lt; 0. (For n&gt;1 the details of sampling may
change.)</p>
<p>Once this is set you can look use this to profile the mutex
contention:</p>
<pre><code>go tool pprof http://localhost:5572/debug/pprof/mutex</code></pre>
<p>Parameters:</p>
<ul>
<li>rate - int</li>
</ul>
<p>Results:</p>
<ul>
<li>previousRate - int</li>
</ul>
<h3 id="debug-set-soft-memory-limit">debug/set-soft-memory-limit: Call
runtime/debug.SetMemoryLimit for setting a soft memory limit for the
runtime.</h3>
<p>SetMemoryLimit provides the runtime with a soft memory limit.</p>
<p>The runtime undertakes several processes to try to respect this
memory limit, including adjustments to the frequency of garbage
collections and returning memory to the underlying system more
aggressively. This limit will be respected even if GOGC=off (or, if
SetGCPercent(-1) is executed).</p>
<p>The input limit is provided as bytes, and includes all memory mapped,
managed, and not released by the Go runtime. Notably, it does not
account for space used by the Go binary and memory external to Go, such
as memory managed by the underlying system on behalf of the process, or
memory managed by non-Go code inside the same process. Examples of
excluded memory sources include: OS kernel memory held on behalf of the
process, memory allocated by C code, and memory mapped by syscall.Mmap
(because it is not managed by the Go runtime).</p>
<p>A zero limit or a limit that's lower than the amount of memory used
by the Go runtime may cause the garbage collector to run nearly
continuously. However, the application may still make progress.</p>
<p>The memory limit is always respected by the Go runtime, so to
effectively disable this behavior, set the limit very high.
math.MaxInt64 is the canonical value for disabling the limit, but values
much greater than the available memory on the underlying system work
just as well.</p>
<p>See https://go.dev/doc/gc-guide for a detailed guide explaining the
soft memory limit in more detail, as well as a variety of common
use-cases and scenarios.</p>
<p>SetMemoryLimit returns the previously set memory limit. A negative
input does not adjust the limit, and allows for retrieval of the
currently set memory limit.</p>
<p>Parameters:</p>
<ul>
<li>mem-limit - int</li>
</ul>

alter the source or destination.</p>
<p>This takes the following parameters:</p>
<ul>
<li>srcFs - a remote name string e.g. "drive:" for the source, "/" for
local filesystem</li>
<li>dstFs - a remote name string e.g. "drive2:" for the destination, "/"
for local filesystem</li>

<li>differ - report all non-matching files (default true)</li>
<li>error - report all files with errors (hashing or reading) (default
true)</li>
</ul>
<p>If you supply the download flag, it will download the data from both
remotes and check them against each other on the fly. This can be useful
for remotes that don't support hashes or if you really want to check all
the data.</p>
<p>If you supply the size-only global flag, it will only compare the
sizes not the hashes as well. Use this for a quick check.</p>
<p>If you supply the checkFileHash option with a valid hash name, the
checkFileFs:checkFileRemote must point to a text file in the SUM format.
This treats the checksum file as the source and dstFs as the
destination. Note that srcFs is not used and should not be supplied in
this case.</p>
<p>Returns:</p>
<ul>
<li>success - true if no error, false otherwise</li>
<li>status - textual summary of check, OK or text string</li>
<li>hashType - hash used in check, may be missing</li>
<li>combined - array of strings of combined report of changes</li>
<li>missingOnSrc - array of strings of all files missing from the
source</li>
<li>missingOnDst - array of strings of all files missing from the
destination</li>
<li>match - array of strings of all matching files</li>

<h3 id="operations-hashsum">operations/hashsum: Produces a hashsum file
for all the objects in the path.</h3>
<p>Produces a hash file for all the objects in the path using the hash
named. The output is in the same format as the standard md5sum/sha1sum
tool.</p>
<p>This takes the following parameters:</p>
<ul>
<li>fs - a remote name string e.g. "drive:" for the source, "/" for
local filesystem
<ul>
<li>this can point to a file and just that file will be returned in the
listing.</li>
</ul></li>
<li>hashType - type of hash to be used</li>
<li>download - check by downloading rather than with hash (boolean)</li>
<li>base64 - output the hashes in base64 rather than hex (boolean)</li>
</ul>
<p>If you supply the download flag, it will download the data from the
remote and create the hash on the fly. This can be useful for remotes
that don't support the given hash or if you really want to check all the
data.</p>
<p>Note that if you wish to supply a checkfile to check hashes against
the current files then you should use operations/check instead of
operations/hashsum.</p>
<p>Returns:</p>
<ul>
<li>hashsum - array of strings of the hashes</li>
<li>hashType - type of hash used</li>
</ul>
<p>Example:</p>
<pre><code>$ rclone rc --loopback operations/hashsum fs=bin hashType=MD5 download=true base64=true
{

<p>This forgets the paths in the directory cache causing them to be
re-read from the remote when needed.</p>
<p>If no paths are passed in then it will forget all the paths in the
directory cache.</p>
<pre><code>rclone rc vfs/forget</code></pre>
<p>Otherwise pass files or dirs in as file=path or dir=path. Any
parameter key starting with file will forget that file and any starting
with dir will forget that dir, e.g.</p>
<pre><code>rclone rc vfs/forget file=hello file2=goodbye dir=home/junk</code></pre>
<p>This command takes an "fs" parameter. If this parameter is not
supplied and if there is only one VFS in use then that VFS will be used.
If there is more than one VFS in use then the "fs" parameter must be
supplied.</p>
<h3 id="vfs-list">vfs/list: List active VFSes.</h3>
<p>This lists the active VFSes.</p>
<p>It returns a list under the key "vfses" where the values are the VFS
names that could be passed to the other VFS commands in the "fs"
parameter.</p>
<h3 id="vfs-poll-interval">vfs/poll-interval: Get the status or update
the value of the poll-interval option.</h3>
<p>Without any parameter given this returns the current status of the
poll-interval setting.</p>
<p>When the interval=duration parameter is set, the poll-interval value
is updated and the polling function is notified. Setting interval=0
disables poll-interval.</p>
<pre><code>rclone rc vfs/poll-interval interval=5m</code></pre>
<p>The timeout=duration parameter can be used to specify a time to wait
for the current poll function to apply the new value. If timeout is less
or equal 0, which is the default, wait indefinitely.</p>
<p>The new poll-interval value will only be active when the timeout is
not reached.</p>
<p>If poll-interval is updated or disabled temporarily, some changes
might not get picked up by the polling function, depending on the used
remote.</p>
<p>This command takes an "fs" parameter. If this parameter is not
supplied and if there is only one VFS in use then that VFS will be used.
If there is more than one VFS in use then the "fs" parameter must be
supplied.</p>
<h3 id="vfs-queue">vfs/queue: Queue info for a VFS.</h3>
<p>This returns info about the upload queue for the selected VFS.</p>
<p>This is only useful if <code>--vfs-cache-mode</code> &gt; off. If you
call it when the <code>--vfs-cache-mode</code> is off, it will return an
empty result.</p>
<pre><code>{
    &quot;queue&quot;: // an array of files queued for upload
    [
        {
            &quot;name&quot;:      &quot;file&quot;,   // string: name (full path) of the file,
            &quot;id&quot;:        123,      // integer: id of this item in the queue,
            &quot;size&quot;:      79,       // integer: size of the file in bytes
            &quot;expiry&quot;:    1.5       // float: time until file is eligible for transfer, lowest goes first
            &quot;tries&quot;:     1,        // integer: number of times we have tried to upload
            &quot;delay&quot;:     5.0,      // float: seconds between upload attempts
            &quot;uploading&quot;: false,    // boolean: true if item is being uploaded
        },
   ],
}</code></pre>
<p>The <code>expiry</code> time is the time until the file is eligible
for being uploaded in floating point seconds. This may go negative. As
rclone only transfers <code>--transfers</code> files at once, only the
lowest <code>--transfers</code> expiry times will have
<code>uploading</code> as <code>true</code>. So there may be files with
negative expiry times for which <code>uploading</code> is
<code>false</code>.</p>
<p>This command takes an "fs" parameter. If this parameter is not
supplied and if there is only one VFS in use then that VFS will be used.
If there is more than one VFS in use then the "fs" parameter must be
supplied.</p>
<h3 id="vfs-queue-set-expiry">vfs/queue-set-expiry: Set the expiry time
for an item queued for upload.</h3>
<p>Use this to adjust the <code>expiry</code> time for an item in the
upload queue. You will need to read the <code>id</code> of the item
using <code>vfs/queue</code> before using this call.</p>
<p>You can then set <code>expiry</code> to a floating point number of
seconds from now when the item is eligible for upload. If you want the
item to be uploaded as soon as possible then set it to a large negative
number (eg -1000000000). If you want the upload of the item to be
delayed for a long time then set it to a large positive number.</p>
<p>Setting the <code>expiry</code> of an item which has already has
started uploading will have no effect - the item will carry on being
uploaded.</p>
<p>This will return an error if called with
<code>--vfs-cache-mode</code> off or if the <code>id</code> passed is
not found.</p>
<p>This takes the following parameters</p>
<ul>
<li><code>fs</code> - select the VFS in use (optional)</li>
<li><code>id</code> - a numeric ID as returned from
<code>vfs/queue</code></li>
<li><code>expiry</code> - a new expiry time as floating point
seconds</li>
<li><code>relative</code> - if set, expiry is to be treated as relative
to the current expiry (optional, boolean)</li>
</ul>
<p>This returns an empty result on success, or an error.</p>
<p>This command takes an "fs" parameter. If this parameter is not
supplied and if there is only one VFS in use then that VFS will be used.
If there is more than one VFS in use then the "fs" parameter must be
supplied.</p>
<h3 id="vfs-refresh">vfs/refresh: Refresh the directory cache.</h3>
<p>This reads the directories for the specified paths and freshens the
directory cache.</p>
<p>If no paths are passed in then it will refresh the root
directory.</p>
<pre><code>rclone rc vfs/refresh</code></pre>
<p>Otherwise pass directories in as dir=path. Any parameter key starting
with dir will refresh that directory, e.g.</p>
<pre><code>rclone rc vfs/refresh dir=home/junk dir2=data/misc</code></pre>
<p>If the parameter recursive=true is given the whole directory tree
will get refreshed. This refresh will use --fast-list if enabled.</p>
<p>This command takes an "fs" parameter. If this parameter is not
supplied and if there is only one VFS in use then that VFS will be used.
If there is more than one VFS in use then the "fs" parameter must be
supplied.</p>
<h3 id="vfs-stats">vfs/stats: Stats for a VFS.</h3>
<p>This returns stats for the selected VFS.</p>
<pre><code>{
    // Status of the disk cache - only present if --vfs-cache-mode &gt; off
    &quot;diskCache&quot;: {
        &quot;bytesUsed&quot;: 0,

    }
}</code></pre>
<p>This command takes an "fs" parameter. If this parameter is not

<li>Go routines:
<code>curl http://localhost:5572/debug/pprof/goroutine?debug=1</code></li>
<li>30-second CPU profile:
<code>go tool pprof http://localhost:5572/debug/pprof/profile</code></li>
<li>5-second execution trace:
<code>wget http://localhost:5572/debug/pprof/trace?seconds=5</code></li>
<li>Goroutine blocking profile

<p>The cloud storage system supports various hash types of the objects.
The hashes are used when transferring data as an integrity check and can
be specifically used with the <code>--checksum</code> flag in syncs and
in the <code>check</code> command.</p>
<p>To use the verify checksums when transferring between cloud storage
systems they must support a common hash type.</p>
<h3 id="modtime">ModTime</h3>
<p>Almost all cloud storage systems store some sort of timestamp on
objects, but several of them not something that is appropriate to use
for syncing. E.g. some backends will only write a timestamp that
represents the time of the upload. To be relevant for syncing it should
be able to store the modification time of the source object. If this is
not the case, rclone will only check the file size by default, though
can be configured to check the file hash (with the
<code>--checksum</code> flag). Ideally it should also be possible to
change the timestamp of an existing file without having to re-upload
it.</p>

<p>Storage systems with a <code>-</code> in the ModTime column, means
the modification read on objects is not the modification time of the
file when uploaded. It is most likely the time the file was uploaded, or
possibly something else (like the time the picture was taken in Google
Photos).</p>
<p>Storage systems with a <code>R</code> (for read-only) in the ModTime
column, means the it keeps modification times on objects, and updates
them when uploading objects, but it does not support changing only the
modification time (<code>SetModTime</code> operation) without
re-uploading, possibly not even without deleting existing first. Some
operations in rclone, such as <code>copy</code> and <code>sync</code>
commands, will automatically check for <code>SetModTime</code> support
and re-upload if necessary to keep the modification times in sync. Other
commands will not work without <code>SetModTime</code> support, e.g.
<code>touch</code> command on an existing file will fail, and changes to
modification time only on a files in a <code>mount</code> will be
silently ignored.</p>
<p>Storage systems with <code>R/W</code> (for read/write) in the ModTime
column, means they do also support modtime-only operations.</p>
<p>Storage systems with <code>D</code> in the ModTime column means that
the following symbols apply to directories as well as files.</p>
<h3 id="case-insensitive">Case Insensitive</h3>
<p>If a cloud storage systems is case sensitive then it is possible to
have two files which differ only in case, e.g. <code>file.txt</code> and
<code>FILE.txt</code>. If a cloud storage system is case insensitive
then that isn't possible.</p>
<p>This can cause problems when syncing between a case insensitive
system and a case sensitive system. The symptom of this is that no
matter how many times you run the sync it never completes fully.</p>
<p>The local filesystem and SFTP may or may not be case sensitive
depending on OS.</p>
<ul>
<li>Windows - usually case insensitive, though case is preserved</li>
<li>OSX - usually case insensitive, though it is possible to format case
sensitive</li>
<li>Linux - usually case sensitive, but there are case insensitive file
systems (e.g. FAT formatted USB keys)</li>
</ul>
<p>Most of the time this doesn't cause any problems as people tend to
avoid files whose name differs only by case even on case sensitive
systems.</p>
<h3 id="duplicate-files">Duplicate files</h3>
<p>If a cloud storage system allows duplicate files then it can have two
objects with the same name.</p>
<p>This confuses rclone greatly when syncing - use the
<code>rclone dedupe</code> command to rename or remove duplicates.</p>
<h3 id="restricted-filenames">Restricted filenames</h3>
<p>Some cloud storage systems might have restrictions on the characters
that are usable in file or directory names. When <code>rclone</code>
detects such a name during a file upload, it will transparently replace
the restricted characters with similar looking Unicode characters. To
handle the different sets of restricted characters for different
backends, rclone uses something it calls <a
href="#encoding">encoding</a>.</p>
<p>This process is designed to avoid ambiguous file names as much as
possible and allow to move files between many cloud storage systems
transparently.</p>
<p>The name shown by <code>rclone</code> to the user or during log
output will only contain a minimal set of <a
href="#restricted-characters">replaced characters</a> to ensure correct
formatting and not necessarily the actual name used on the cloud
storage.</p>
<p>This transformation is reversed when downloading a file or parsing
<code>rclone</code> arguments. For example, when uploading a file named
<code>my file?.txt</code> to Onedrive, it will be displayed as
<code>my file?.txt</code> on the console, but stored as
<code>my file？.txt</code> to Onedrive (the <code>?</code> gets replaced
by the similar looking <code>？</code> character, the so-called
"fullwidth question mark"). The reverse transformation allows to read a
file <code>unusual/name.txt</code> from Google Drive, by passing the
name <code>unusual／name.txt</code> on the command line (the
<code>/</code> needs to be replaced by the similar looking
<code>／</code> character).</p>
<h4 id="restricted-filenames-caveats">Caveats</h4>
<p>The filename encoding system works well in most cases, at least where
file names are written in English or similar languages. You might not
even notice it: It just works. In some cases it may lead to issues,
though. E.g. when file names are written in Chinese, or Japanese, where
it is always the Unicode fullwidth variants of the punctuation marks
that are used.</p>
<p>On Windows, the characters <code>:</code>, <code>*</code> and
<code>?</code> are examples of restricted characters. If these are used
in filenames on a remote that supports it, Rclone will transparently
convert them to their fullwidth Unicode variants <code>＊</code>,
<code>？</code> and <code>：</code> when downloading to Windows, and
back again when uploading. This way files with names that are not
allowed on Windows can still be stored.</p>
<p>However, if you have files on your Windows system originally with
these same Unicode characters in their names, they will be included in
the same conversion process. E.g. if you create a file in your Windows
filesystem with name <code>Test：1.jpg</code>, where <code>：</code> is
the Unicode fullwidth colon symbol, and use rclone to upload it to
Google Drive, which supports regular <code>:</code> (halfwidth question
mark), rclone will replace the fullwidth <code>:</code> with the
halfwidth <code>:</code> and store the file as <code>Test:1.jpg</code>
in Google Drive. Since both Windows and Google Drive allows the name
<code>Test：1.jpg</code>, it would probably be better if rclone just
kept the name as is in this case.</p>
<p>With the opposite situation; if you have a file named
<code>Test:1.jpg</code>, in your Google Drive, e.g. uploaded from a
Linux system where <code>:</code> is valid in file names. Then later use
rclone to copy this file to your Windows computer you will notice that
on your local disk it gets renamed to <code>Test：1.jpg</code>. The
original filename is not legal on Windows, due to the <code>:</code>,
and rclone therefore renames it to make the copy possible. That is all
good. However, this can also lead to an issue: If you already had a
<em>different</em> file named <code>Test：1.jpg</code> on Windows, and
then use rclone to copy either way. Rclone will then treat the file
originally named <code>Test:1.jpg</code> on Google Drive and the file
originally named <code>Test：1.jpg</code> on Windows as the same file,
and replace the contents from one with the other.</p>
<p>Its virtually impossible to handle all cases like these correctly in
all situations, but by customizing the <a href="#encoding">encoding
option</a>, changing the set of characters that rclone should convert,
you should be able to create a configuration that works well for your
specific situation. See also the <a
href="https://rclone.org/overview/#encoding-example-windows">example</a>
below.</p>
<p>(Windows was used as an example of a file system with many restricted
characters, and Google drive a storage system with few.)</p>
<h4 id="restricted-characters">Default restricted characters</h4>
<p>The table below shows the characters that are replaced by
default.</p>
<p>When a replacement character is found in a filename, this character
will be escaped with the <code>‛</code> character to avoid ambiguous
file names. (e.g. a file named <code>␀.txt</code> would shown as
<code>‛␀.txt</code>)</p>
<p>Each cloud storage backend can use a different set of characters,
which will be specified in the documentation for each backend.</p>

<h4 id="invalid-utf8">Invalid UTF-8 bytes</h4>
<p>Some backends only support a sequence of well formed UTF-8 bytes as
file or directory names.</p>
<p>In this case all invalid UTF-8 bytes will be replaced with a quoted
representation of the byte value to allow uploading a file to such a
backend. For example, the invalid byte <code>0xFE</code> will be encoded
as <code>‛FE</code>.</p>
<p>A common source of invalid UTF-8 bytes are local filesystems, that
store names in a different encoding than UTF-8 or UTF-16, like latin1.
See the <a href="https://rclone.org/local/#filenames">local
filenames</a> section for details.</p>
<h4 id="encoding">Encoding option</h4>
<p>Most backends have an encoding option, specified as a flag
<code>--backend-encoding</code> where <code>backend</code> is the name
of the backend, or as a config parameter <code>encoding</code> (you'll
need to select the Advanced config in <code>rclone config</code> to see
it).</p>
<p>This will have default value which encodes and decodes characters in
such a way as to preserve the maximum number of characters (see
above).</p>
<p>However this can be incorrect in some scenarios, for example if you
have a Windows file system with Unicode fullwidth characters
<code>＊</code>, <code>？</code> or <code>：</code>, that you want to
remain as those characters on the remote rather than being translated to
regular (halfwidth) <code>*</code>, <code>?</code> and
<code>:</code>.</p>
<p>The <code>--backend-encoding</code> flags allow you to change that.
You can disable the encoding completely with
<code>--backend-encoding Raw</code> or set <code>encoding = Raw</code>
in the config file.</p>
<p>Encoding takes a comma separated list of encodings. You can see the
list of all possible values by passing an invalid value to this flag,
e.g. <code>--local-encoding "help"</code>. The command
<code>rclone help flags encoding</code> will show you the defaults for
the backends.</p>

<p>¹ Encoding from NUL 0x00 to ␀ is always implicit except when using
Raw. It was previously incorrectly documented as disabling encoding, and
to maintain backward compatibility, its behavior has not been
changed.</p>
<h5 id="encoding-example-ftp">Encoding example: FTP</h5>
<p>To take a specific example, the FTP backend's default encoding is</p>
<pre class="text"><code>--ftp-encoding &quot;Slash,Del,Ctl,RightSpace,Dot&quot;</code></pre>
<p>However, let's say the FTP server is running on Windows and can't
have any of the invalid Windows characters in file names. You are
backing up Linux servers to this FTP server which do have those
characters in file names. So you would add the Windows set which are</p>
<pre class="text"><code>Slash,LtGt,DoubleQuote,Colon,Question,Asterisk,Pipe,BackSlash,Ctl,RightSpace,RightPeriod,InvalidUtf8,Dot</code></pre>
<p>to the existing ones, giving:</p>
<pre class="text"><code>Slash,LtGt,DoubleQuote,Colon,Question,Asterisk,Pipe,BackSlash,Ctl,RightSpace,RightPeriod,InvalidUtf8,Dot,Del,RightSpace</code></pre>
<p>This can be specified using the <code>--ftp-encoding</code> flag or
using an <code>encoding</code> parameter in the config file.</p>
<h5 id="encoding-example-windows">Encoding example: Windows</h5>
<p>As a nother example, take a Windows system where there is a file with
name <code>Test：1.jpg</code>, where <code>：</code> is the Unicode
fullwidth colon symbol. When using rclone to copy this to a remote which
supports <code>:</code>, the regular (halfwidth) colon (such as Google
Drive), you will notice that the file gets renamed to
<code>Test:1.jpg</code>.</p>
<p>To avoid this you can change the set of characters rclone should
convert for the local filesystem, using command-line argument
<code>--local-encoding</code>. Rclone's default behavior on Windows
corresponds to</p>
<pre class="text"><code>--local-encoding &quot;Slash,LtGt,DoubleQuote,Colon,Question,Asterisk,Pipe,BackSlash,Ctl,RightSpace,RightPeriod,InvalidUtf8,Dot&quot;</code></pre>
<p>If you want to use fullwidth characters <code>：</code>,
<code>＊</code> and <code>？</code> in your filenames without rclone
changing them when uploading to a remote, then set the same as the
default value but without <code>Colon,Question,Asterisk</code>:</p>
<pre class="text"><code>--local-encoding &quot;Slash,LtGt,DoubleQuote,Pipe,BackSlash,Ctl,RightSpace,RightPeriod,InvalidUtf8,Dot&quot;</code></pre>
<p>Alternatively, you can disable the conversion of any characters with
<code>--local-encoding Raw</code>.</p>
<p>Instead of using command-line argument <code>--local-encoding</code>,
you may also set it as <a
href="https://rclone.org/docs/#environment-variables">environment
variable</a> <code>RCLONE_LOCAL_ENCODING</code>, or <a
href="https://rclone.org/docs/#configure">configure</a> a remote of type
<code>local</code> in your config, and set the <code>encoding</code>
option there.</p>
<p>The risk by doing this is that if you have a filename with the
regular (halfwidth) <code>:</code>, <code>*</code> and <code>?</code> in
your cloud storage, and you try to download it to your Windows
filesystem, this will fail. These characters are not valid in filenames
on Windows, and you have told rclone not to work around this by
converting them to valid fullwidth variants.</p>
<h3 id="mime-type">MIME Type</h3>
<p>MIME types (also known as media types) classify types of documents
using a simple text classification, e.g. <code>text/html</code> or
<code>application/pdf</code>.</p>
<p>Some cloud storage systems support reading (<code>R</code>) the MIME
type of objects and some support writing (<code>W</code>) the MIME type
of objects.</p>
<p>The MIME type can be important if you are serving files directly to
HTTP from the storage system.</p>
<p>If you are copying from a remote which supports reading
(<code>R</code>) to a remote which supports writing (<code>W</code>)
then rclone will preserve the MIME types. Otherwise they will be guessed
from the extension, or the remote itself may assign the MIME type.</p>
<h3 id="metadata-1">Metadata</h3>
<p>Backends may or may support reading or writing metadata. They may
support reading and writing system metadata (metadata intrinsic to that
backend) and/or user metadata (general purpose metadata).</p>
<p>The levels of metadata support are</p>

</table>
<p>¹ Note Swift implements this in order to delete directory markers but
it doesn't actually have a quicker way of deleting files other than
deleting them individually.</p>
<p>² Storj implements this efficiently only for entire buckets. If
purging a directory inside a bucket, files are deleted individually.</p>
<p>³ StreamUpload is not supported with Nextcloud</p>
<p>⁴ Use the <code>--sftp-copy-is-hardlink</code> flag to enable.</p>
<p>⁵ Use the <code>--onedrive-delta</code> flag to enable.</p>
<h3 id="purge">Purge</h3>
<p>This deletes a directory quicker than just deleting all the files in
the directory.</p>
<h3 id="copy">Copy</h3>
<p>Used when copying an object to and from the same remote. This known
as a server-side copy so you can copy a file without downloading it and
uploading it again. It is used if you use <code>rclone copy</code> or
<code>rclone move</code> if the remote doesn't support <code>Move</code>
directly.</p>
<p>If the server doesn't support <code>Copy</code> directly then for
copy operations the file is downloaded then re-uploaded.</p>
<h3 id="move">Move</h3>
<p>Used when moving/renaming an object on the same remote. This is known
as a server-side move of a file. This is used in
<code>rclone move</code> if the server doesn't support
<code>DirMove</code>.</p>
<p>If the server isn't capable of <code>Move</code> then rclone
simulates it with <code>Copy</code> then delete. If the server doesn't
support <code>Copy</code> then rclone will download the file and
re-upload it.</p>
<h3 id="dirmove">DirMove</h3>
<p>This is used to implement <code>rclone move</code> to move a
directory if possible. If it isn't then it will use <code>Move</code> on
each file (which falls back to <code>Copy</code> then download and
upload - see <code>Move</code> section).</p>
<h3 id="cleanup">CleanUp</h3>
<p>This is used for emptying the trash for a remote by
<code>rclone cleanup</code>.</p>
<p>If the server can't do <code>CleanUp</code> then
<code>rclone cleanup</code> will return an error.</p>
<p>‡‡ Note that while Box implements this it has to delete every file
individually so it will be slower than emptying the trash via the
WebUI</p>
<h3 id="listr">ListR</h3>
<p>The remote supports a recursive list to list all the contents beneath
a directory quickly. This enables the <code>--fast-list</code> flag to
work. See the <a href="https://rclone.org/docs/#fast-list">rclone
docs</a> for more details.</p>
<h3 id="streamupload">StreamUpload</h3>
<p>Some remotes allow files to be uploaded without knowing the file size
in advance. This allows certain operations to work without spooling the
file to local disk first, e.g. <code>rclone rcat</code>.</p>
<h3 id="multithreadupload">MultithreadUpload</h3>
<p>Some remotes allow transfers to the remote to be sent as chunks in
parallel. If this is supported then rclone will use multi-thread copying
to transfer files much faster.</p>
<h3 id="linksharing">LinkSharing</h3>
<p>Sets the necessary permissions on a file or folder and prints a link
that allows others to access them, even if they don't have an account on
the particular cloud provider.</p>
<h3 id="about-1">About</h3>
<p>Rclone <code>about</code> prints quota information for a remote.
Typical output includes bytes used, free, quota and in trash.</p>
<p>If a remote lacks about capability
<code>rclone about remote:</code>returns an error.</p>
<p>Backends without about capability cannot determine free space for an
rclone mount, or use policy <code>mfs</code> (most free space) as a
member of an rclone union remote.</p>
<p>See <a href="https://rclone.org/commands/rclone_about/">rclone about
command</a></p>
<h3 id="emptydir">EmptyDir</h3>
<p>The remote supports empty directories. See <a
href="https://rclone.org/bugs/#limitations">Limitations</a> for details.
Most Object/Bucket-based remotes do not support this.</p>

<h1 id="docker-volume-plugin">Docker Volume Plugin</h1>
<h2 id="introduction">Introduction</h2>
<p>Docker 1.9 has added support for creating <a
href="https://docs.docker.com/storage/volumes/">named volumes</a> via <a
href="https://docs.docker.com/engine/reference/commandline/volume_create/">command-line
interface</a> and mounting them in containers as a way to share data
between them. Since Docker 1.10 you can create named volumes with <a
href="https://docs.docker.com/compose/">Docker Compose</a> by
descriptions in <a
href="https://docs.docker.com/compose/compose-file/compose-file-v2/#volume-configuration-reference">docker-compose.yml</a>
files for use by container groups on a single host. As of Docker 1.12
volumes are supported by <a
href="https://docs.docker.com/engine/swarm/key-concepts/">Docker
Swarm</a> included with Docker Engine and created from descriptions in
<a
href="https://docs.docker.com/compose/compose-file/compose-file-v3/#volume-configuration-reference">swarm
compose v3</a> files for use with <em>swarm stacks</em> across multiple
cluster nodes.</p>
<p><a
href="https://docs.docker.com/engine/extend/plugins_volume/">Docker
Volume Plugins</a> augment the default <code>local</code> volume driver
included in Docker with stateful volumes shared across containers and
hosts. Unlike local volumes, your data will <em>not</em> be deleted when
such volume is removed. Plugins can run managed by the docker daemon, as
a native system service (under systemd, <em>sysv</em> or
<em>upstart</em>) or as a standalone executable. Rclone can run as
docker volume plugin in all these modes. It interacts with the local
docker daemon via <a
href="https://docs.docker.com/engine/extend/plugin_api/">plugin API</a>
and handles mounting of remote file systems into docker containers so it
must run on the same host as the docker daemon or on every Swarm
node.</p>
<h2 id="getting-started">Getting started</h2>
<p>In the first example we will use the <a
href="https://rclone.org/sftp/">SFTP</a> rclone volume with Docker
engine on a standalone Ubuntu machine.</p>
<p>Start from <a
href="https://docs.docker.com/engine/install/">installing Docker</a> on
the host.</p>
<p>The <em>FUSE</em> driver is a prerequisite for rclone mounting and
should be installed on host:</p>
<pre class="console"><code>sudo apt-get -y install fuse3</code></pre>
<p>Create two directories required by rclone docker plugin:</p>
<pre class="console"><code>sudo mkdir -p /var/lib/docker-plugins/rclone/config
sudo mkdir -p /var/lib/docker-plugins/rclone/cache</code></pre>
<p>Install the managed rclone docker plugin for your architecture (here
<code>amd64</code>):</p>
<pre class="console"><code>docker plugin install rclone/docker-volume-rclone:amd64 args=&quot;-v&quot; --alias rclone --grant-all-permissions
docker plugin list</code></pre>
<p>Create your <a href="https://rclone.org/sftp/#standard-options">SFTP
volume</a>:</p>
<pre class="console"><code>docker volume create firstvolume -d rclone -o type=sftp -o sftp-host=_hostname_ -o sftp-user=_username_ -o sftp-pass=_password_ -o allow-other=true</code></pre>
<p>Note that since all options are static, you don't even have to run
<code>rclone config</code> or create the <code>rclone.conf</code> file
(but the <code>config</code> directory should still be present). In the
simplest case you can use <code>localhost</code> as <em>hostname</em>
and your SSH credentials as <em>username</em> and <em>password</em>. You
can also change the remote path to your home directory on the host, for
example <code>-o path=/home/username</code>.</p>
<p>Time to create a test container and mount the volume into it:</p>
<pre class="console"><code>docker run --rm -it -v firstvolume:/mnt --workdir /mnt ubuntu:latest bash</code></pre>
<p>If all goes well, you will enter the new container and change right
to the mounted SFTP remote. You can type <code>ls</code> to list the
mounted directory or otherwise play with it. Type <code>exit</code> when
you are done. The container will stop but the volume will stay, ready to
be reused. When it's not needed anymore, remove it:</p>
<pre class="console"><code>docker volume list
docker volume remove firstvolume</code></pre>
<p>Now let us try <strong>something more elaborate</strong>: <a
href="https://rclone.org/drive/">Google Drive</a> volume on multi-node
Docker Swarm.</p>
<p>You should start from installing Docker and FUSE, creating plugin
directories and installing rclone plugin on <em>every</em> swarm node.
Then <a href="https://docs.docker.com/engine/swarm/swarm-mode/">setup
the Swarm</a>.</p>
<p>Google Drive volumes need an access token which can be setup via web
browser and will be periodically renewed by rclone. The managed plugin
cannot run a browser so we will use a technique similar to the <a
href="https://rclone.org/remote_setup/">rclone setup on a headless
box</a>.</p>
<p>Run <a
href="https://rclone.org/commands/rclone_config_create/">rclone
config</a> on <em>another</em> machine equipped with <em>web
browser</em> and graphical user interface. Create the <a
href="https://rclone.org/drive/#standard-options">Google Drive
remote</a>. When done, transfer the resulting <code>rclone.conf</code>
to the Swarm cluster and save as
<code>/var/lib/docker-plugins/rclone/config/rclone.conf</code> on
<em>every</em> node. By default this location is accessible only to the
root user so you will need appropriate privileges. The resulting config
will look like this:</p>

<p>and run the stack:</p>
<pre class="console"><code>docker stack deploy example -c ./example.yml</code></pre>
<p>After a few seconds docker will spread the parsed stack description
over cluster, create the <code>example_heimdall</code> service on port
<em>8080</em>, run service containers on one or more cluster nodes and
request the <code>example_configdata</code> volume from rclone plugins
on the node hosts. You can use the following commands to confirm
results:</p>
<pre class="console"><code>docker service ls
docker service ps example_heimdall
docker volume ls</code></pre>
<p>Point your browser to <code>http://cluster.host.address:8080</code>
and play with the service. Stop it with
<code>docker stack remove example</code> when you are done. Note that
the <code>example_configdata</code> volume(s) created on demand at the
cluster nodes will not be automatically removed together with the stack
but stay for future reuse. You can remove them manually by invoking the
<code>docker volume remove example_configdata</code> command on every
node.</p>
<h2 id="creating-volumes-via-cli">Creating Volumes via CLI</h2>
<p>Volumes can be created with <a
href="https://docs.docker.com/engine/reference/commandline/volume_create/">docker
volume create</a>. Here are a few examples:</p>
<pre class="console"><code>docker volume create vol1 -d rclone -o remote=storj: -o vfs-cache-mode=full
docker volume create vol2 -d rclone -o remote=:storj,access_grant=xxx:heimdall
docker volume create vol3 -d rclone -o type=storj -o path=heimdall -o storj-access-grant=xxx -o poll-interval=0</code></pre>
<p>Note the <code>-d rclone</code> flag that tells docker to request
volume from the rclone driver. This works even if you installed managed
driver by its full name <code>rclone/docker-volume-rclone</code> because
you provided the <code>--alias rclone</code> option.</p>
<p>Volumes can be inspected as follows:</p>
<pre class="console"><code>docker volume list
docker volume inspect vol1</code></pre>
<h2 id="volume-configuration">Volume Configuration</h2>
<p>Rclone flags and volume options are set via the <code>-o</code> flag
to the <code>docker volume create</code> command. They include
backend-specific parameters as well as mount and <em>VFS</em> options.
Also there are a few special <code>-o</code> options:
<code>remote</code>, <code>fs</code>, <code>type</code>,
<code>path</code>, <code>mount-type</code> and <code>persist</code>.</p>
<p><code>remote</code> determines an existing remote name from the
config file, with trailing colon and optionally with a remote path. See
the full syntax in the <a
href="https://rclone.org/docs/#syntax-of-remote-paths">rclone
documentation</a>. This option can be aliased as <code>fs</code> to
prevent confusion with the <em>remote</em> parameter of such backends as
<em>crypt</em> or <em>alias</em>.</p>
<p>The <code>remote=:backend:dir/subdir</code> syntax can be used to
create <a href="https://rclone.org/docs/#backend-path-to-dir">on-the-fly
(config-less) remotes</a>, while the <code>type</code> and
<code>path</code> options provide a simpler alternative for this. Using
two split options</p>
<pre class="text"><code>-o type=backend -o path=dir/subdir</code></pre>
<p>is equivalent to the combined syntax</p>
<pre class="text"><code>-o remote=:backend:dir/subdir</code></pre>
<p>but is arguably easier to parameterize in scripts. The
<code>path</code> part is optional.</p>
<p><a
href="https://rclone.org/commands/rclone_serve_docker/#options">Mount
and VFS options</a> as well as <a
href="https://rclone.org/flags/#backend">backend parameters</a> are
named like their twin command-line flags without the <code>--</code> CLI
prefix. Optionally you can use underscores instead of dashes in option
names. For example, <code>--vfs-cache-mode full</code> becomes
<code>-o vfs-cache-mode=full</code> or
<code>-o vfs_cache_mode=full</code>. Boolean CLI flags without value
will gain the <code>true</code> value, e.g. <code>--allow-other</code>
becomes <code>-o allow-other=true</code> or
<code>-o allow_other=true</code>.</p>
<p>Please note that you can provide parameters only for the backend
immediately referenced by the backend type of mounted
<code>remote</code>. If this is a wrapping backend like <em>alias,
chunker or crypt</em>, you cannot provide options for the referred to
remote or backend. This limitation is imposed by the rclone connection
string parser. The only workaround is to feed plugin with
<code>rclone.conf</code> or configure plugin arguments (see below).</p>
<h2 id="special-volume-options">Special Volume Options</h2>
<p><code>mount-type</code> determines the mount method and in general
can be one of: <code>mount</code>, <code>cmount</code>, or
<code>mount2</code>. This can be aliased as <code>mount_type</code>. It
should be noted that the managed rclone docker plugin currently does not
support the <code>cmount</code> method and <code>mount2</code> is rarely
needed. This option defaults to the first found method, which is usually
<code>mount</code> so you generally won't need it.</p>
<p><code>persist</code> is a reserved boolean (true/false) option. In
future it will allow to persist on-the-fly remotes in the plugin
<code>rclone.conf</code> file.</p>
<h2 id="connection-strings-1">Connection Strings</h2>
<p>The <code>remote</code> value can be extended with <a
href="https://rclone.org/docs/#connection-strings">connection
strings</a> as an alternative way to supply backend parameters. This is
equivalent to the <code>-o</code> backend options with one <em>syntactic
difference</em>. Inside connection string the backend prefix must be
dropped from parameter names but in the <code>-o param=value</code>
array it must be present. For instance, compare the following option
array</p>
<pre class="text"><code>-o remote=:sftp:/home -o sftp-host=localhost</code></pre>
<p>with equivalent connection string:</p>
<pre class="text"><code>-o remote=:sftp,host=localhost:/home</code></pre>
<p>This difference exists because flag options <code>-o key=val</code>
include not only backend parameters but also mount/VFS flags and
possibly other settings. Also it allows to discriminate the
<code>remote</code> option from the <code>crypt-remote</code> (or
similarly named backend parameters) and arguably simplifies scripting
due to clearer value substitution.</p>
<h2 id="using-with-swarm-or-compose">Using with Swarm or Compose</h2>
<p>Both <em>Docker Swarm</em> and <em>Docker Compose</em> use <a
href="http://yaml.org/spec/1.2/spec.html">YAML</a>-formatted text files
to describe groups (stacks) of containers, their properties, networks
and volumes. <em>Compose</em> uses the <a
href="https://docs.docker.com/compose/compose-file/compose-file-v2/#volume-configuration-reference">compose
v2</a> format, <em>Swarm</em> uses the <a
href="https://docs.docker.com/compose/compose-file/compose-file-v3/#volume-configuration-reference">compose
v3</a> format. They are mostly similar, differences are explained in the
<a
href="https://docs.docker.com/compose/compose-file/compose-versioning/#upgrading">docker
documentation</a>.</p>
<p>Volumes are described by the children of the top-level
<code>volumes:</code> node. Each of them should be named after its
volume and have at least two elements, the self-explanatory
<code>driver: rclone</code> value and the <code>driver_opts:</code>
structure playing the same role as <code>-o key=val</code> CLI
flags:</p>

<p>Notice a few important details:</p>
<ul>
<li>YAML prefers <code>_</code> in option names instead of
<code>-</code>.</li>
<li>YAML treats single and double quotes interchangeably. Simple strings
and integers can be left unquoted.</li>
<li>Boolean values must be quoted like <code>'true'</code> or
<code>"false"</code> because these two words are reserved by YAML.</li>
<li>The filesystem string is keyed with <code>remote</code> (or with
<code>fs</code>). Normally you can omit quotes here, but if the string
ends with colon, you <strong>must</strong> quote it like
<code>remote: "storage_box:"</code>.</li>
<li>YAML is picky about surrounding braces in values as this is in fact
another <a href="http://yaml.org/spec/1.2/spec.html#id2790832">syntax
for key/value mappings</a>. For example, JSON access tokens usually
contain double quotes and surrounding braces, so you must put them in
single quotes.</li>
</ul>
<h2 id="installing-as-managed-plugin">Installing as Managed Plugin</h2>
<p>Docker daemon can install plugins from an image registry and run them
managed. We maintain the <a
href="https://hub.docker.com/p/rclone/docker-volume-rclone/">docker-volume-rclone</a>
plugin image on <a href="https://hub.docker.com">Docker Hub</a>.</p>
<p>Rclone volume plugin requires <strong>Docker Engine &gt;=
19.03.15</strong></p>
<p>The plugin requires presence of two directories on the host before it
can be installed. Note that plugin will <strong>not</strong> create them
automatically. By default they must exist on host at the following
locations (though you can tweak the paths):</p>
<ul>
<li><code>/var/lib/docker-plugins/rclone/config</code> is reserved for
the <code>rclone.conf</code> config file and <strong>must</strong> exist
even if it's empty and the config file is not present.</li>
<li><code>/var/lib/docker-plugins/rclone/cache</code> holds the plugin
state file as well as optional VFS caches.</li>
</ul>
<p>You can <a
href="https://docs.docker.com/engine/reference/commandline/plugin_install/">install
managed plugin</a> with default settings as follows:</p>
<pre class="console"><code>docker plugin install rclone/docker-volume-rclone:amd64 --grant-all-permissions --alias rclone</code></pre>
<p>The <code>:amd64</code> part of the image specification after colon
is called a <em>tag</em>. Usually you will want to install the latest
plugin for your architecture. In this case the tag will just name it,
like <code>amd64</code> above. The following plugin architectures are
currently available:</p>
<ul>
<li><code>amd64</code></li>
<li><code>arm64</code></li>
<li><code>arm-v7</code></li>
</ul>
<p>Sometimes you might want a concrete plugin version, not the latest
one. Then you should use image tag in the form
<code>:ARCHITECTURE-VERSION</code>. For example, to install plugin
version <code>v1.56.2</code> on architecture <code>arm64</code> you will
use tag <code>arm64-1.56.2</code> (note the removed <code>v</code>) so
the full image specification becomes
<code>rclone/docker-volume-rclone:arm64-1.56.2</code>.</p>
<p>We also provide the <code>latest</code> plugin tag, but since docker
does not support multi-architecture plugins as of the time of this
writing, this tag is currently an <strong>alias for
<code>amd64</code></strong>. By convention the <code>latest</code> tag
is the default one and can be omitted, thus both
<code>rclone/docker-volume-rclone:latest</code> and just
<code>rclone/docker-volume-rclone</code> will refer to the latest plugin
release for the <code>amd64</code> platform.</p>
<p>Also the <code>amd64</code> part can be omitted from the versioned
rclone plugin tags. For example, rclone image reference
<code>rclone/docker-volume-rclone:amd64-1.56.2</code> can be abbreviated
as <code>rclone/docker-volume-rclone:1.56.2</code> for convenience.
However, for non-intel architectures you still have to use the full tag
as <code>amd64</code> or <code>latest</code> will fail to start.</p>
<p>Managed plugin is in fact a special container running in a namespace
separate from normal docker containers. Inside it runs the
<code>rclone serve docker</code> command. The config and cache
directories are bind-mounted into the container at start. The docker
daemon connects to a unix socket created by the command inside the
container. The command creates on-demand remote mounts right inside,
then docker machinery propagates them through kernel mount namespaces
and bind-mounts into requesting user containers.</p>
<p>You can tweak a few plugin settings after installation when it's
disabled (not in use), for instance:</p>
<pre class="console"><code>docker plugin disable rclone
docker plugin set rclone RCLONE_VERBOSE=2 config=/etc/rclone args=&quot;--vfs-cache-mode=writes --allow-other&quot;
docker plugin enable rclone
docker plugin inspect rclone</code></pre>
<p>Note that if docker refuses to disable the plugin, you should find
and remove all active volumes connected with it as well as containers
and swarm services that use them. This is rather tedious so please
carefully plan in advance.</p>
<p>You can tweak the following settings: <code>args</code>,
<code>config</code>, <code>cache</code>, <code>HTTP_PROXY</code>,
<code>HTTPS_PROXY</code>, <code>NO_PROXY</code> and
<code>RCLONE_VERBOSE</code>. It's <em>your</em> task to keep plugin
settings in sync across swarm cluster nodes.</p>
<p><code>args</code> sets command-line arguments for the
<code>rclone serve docker</code> command (<em>none</em> by default).
Arguments should be separated by space so you will normally want to put
them in quotes on the <a
href="https://docs.docker.com/engine/reference/commandline/plugin_set/">docker
plugin set</a> command line. Both <a
href="https://rclone.org/commands/rclone_serve_docker/#options">serve
docker flags</a> and <a href="https://rclone.org/flags/">generic rclone
flags</a> are supported, including backend parameters that will be used
as defaults for volume creation. Note that plugin will fail (due to <a
href="https://github.com/moby/moby/blob/v20.10.7/plugin/v2/plugin.go#L195">this
docker bug</a>) if the <code>args</code> value is empty. Use e.g.
<code>args="-v"</code> as a workaround.</p>
<p><code>config=/host/dir</code> sets alternative host location for the
config directory. Plugin will look for <code>rclone.conf</code> here.
It's not an error if the config file is not present but the directory
must exist. Please note that plugin can periodically rewrite the config
file, for example when it renews storage access tokens. Keep this in
mind and try to avoid races between the plugin and other instances of
rclone on the host that might try to change the config simultaneously
resulting in corrupted <code>rclone.conf</code>. You can also put stuff
like private key files for SFTP remotes in this directory. Just note
that it's bind-mounted inside the plugin container at the predefined
path <code>/data/config</code>. For example, if your key file is named
<code>sftp-box1.key</code> on the host, the corresponding volume config
option should read
<code>-o sftp-key-file=/data/config/sftp-box1.key</code>.</p>
<p><code>cache=/host/dir</code> sets alternative host location for the
<em>cache</em> directory. The plugin will keep VFS caches here. Also it
will create and maintain the <code>docker-plugin.state</code> file in
this directory. When the plugin is restarted or reinstalled, it will
look in this file to recreate any volumes that existed previously.
However, they will not be re-mounted into consuming containers after
restart. Usually this is not a problem as the docker daemon normally
will restart affected user containers after failures, daemon restarts or
host reboots.</p>
<p><code>RCLONE_VERBOSE</code> sets plugin verbosity from <code>0</code>
(errors only, by default) to <code>2</code> (debugging). Verbosity can
be also tweaked via <code>args="-v [-v] ..."</code>. Since arguments are
more generic, you will rarely need this setting. The plugin output by
default feeds the docker daemon log on local host. Log entries are
reflected as <em>errors</em> in the docker log but retain their actual
level assigned by rclone in the encapsulated message string.</p>
<p><code>HTTP_PROXY</code>, <code>HTTPS_PROXY</code>,
<code>NO_PROXY</code> customize the plugin proxy settings.</p>
<p>You can set custom plugin options right when you install it, <em>in
one go</em>:</p>
<pre class="console"><code>docker plugin remove rclone
docker plugin install rclone/docker-volume-rclone:amd64 \
       --alias rclone --grant-all-permissions \
       args=&quot;-v --allow-other&quot; config=/etc/rclone
docker plugin inspect rclone</code></pre>
<h2 id="healthchecks">Healthchecks</h2>
<p>The docker plugin volume protocol doesn't provide a way for plugins
to inform the docker daemon that a volume is (un-)available. As a
workaround you can setup a healthcheck to verify that the mount is
responding, for example:</p>
<div class="sourceCode" id="cb900"><pre

<h2 id="running-plugin-under-systemd">Running Plugin under Systemd</h2>
<p>In most cases you should prefer managed mode. Moreover, MacOS and
Windows do not support native Docker plugins. Please use managed mode on
these systems. Proceed further only if you are on Linux.</p>
<p>First, <a href="https://rclone.org/install/">install rclone</a>. You
can just run it (type <code>rclone serve docker</code> and hit enter)
for the test.</p>
<p>Install <em>FUSE</em>:</p>
<pre class="console"><code>sudo apt-get -y install fuse</code></pre>
<p>Download two systemd configuration files: <a
href="https://raw.githubusercontent.com/rclone/rclone/master/contrib/docker-plugin/systemd/docker-volume-rclone.service">docker-volume-rclone.service</a>
and <a
href="https://raw.githubusercontent.com/rclone/rclone/master/contrib/docker-plugin/systemd/docker-volume-rclone.socket">docker-volume-rclone.socket</a>.</p>
<p>Put them to the <code>/etc/systemd/system/</code> directory:</p>
<pre class="console"><code>cp docker-volume-plugin.service /etc/systemd/system/
cp docker-volume-plugin.socket  /etc/systemd/system/</code></pre>
<p>Please note that all commands in this section must be run as
<em>root</em> but we omit <code>sudo</code> prefix for brevity. Now
create directories required by the service:</p>
<pre class="console"><code>mkdir -p /var/lib/docker-volumes/rclone
mkdir -p /var/lib/docker-plugins/rclone/config
mkdir -p /var/lib/docker-plugins/rclone/cache</code></pre>
<p>Run the docker plugin service in the socket activated mode:</p>
<pre class="console"><code>systemctl daemon-reload
systemctl start docker-volume-rclone.service
systemctl enable docker-volume-rclone.socket
systemctl start docker-volume-rclone.socket
systemctl restart docker</code></pre>
<p>Or run the service directly:</p>
<ul>
<li>run <code>systemctl daemon-reload</code> to let systemd pick up new
config</li>
<li>run <code>systemctl enable docker-volume-rclone.service</code> to
make the new service start automatically when you power on your
machine.</li>
<li>run <code>systemctl start docker-volume-rclone.service</code> to
start the service now.</li>
<li>run <code>systemctl restart docker</code> to restart docker daemon
and let it detect the new plugin socket. Note that this step is not
needed in managed mode where docker knows about plugin state
changes.</li>
</ul>
<p>The two methods are equivalent from the user perspective, but I
personally prefer socket activation.</p>
<h2 id="troubleshooting-1">Troubleshooting</h2>
<p>You can <a
href="https://docs.docker.com/engine/extend/#debugging-plugins">see
managed plugin settings</a> with</p>
<pre class="console"><code>docker plugin list
docker plugin inspect rclone</code></pre>
<p>Note that docker (including latest 20.10.7) will not show actual
values of <code>args</code>, just the defaults.</p>
<p>Use <code>journalctl --unit docker</code> to see managed plugin
output as part of the docker daemon log. Note that docker reflects
plugin lines as <em>errors</em> but their actual level can be seen from
encapsulated message string.</p>
<p>You will usually install the latest version of managed plugin for
your platform. Use the following commands to print the actual installed
version:</p>
<pre class="console"><code>PLUGID=$(docker plugin list --no-trunc | awk &#39;/rclone/{print$1}&#39;)
sudo runc --root /run/docker/runtime-runc/plugins.moby exec $PLUGID rclone version</code></pre>
<p>You can even use <code>runc</code> to run shell inside the plugin
container:</p>
<pre class="console"><code>sudo runc --root /run/docker/runtime-runc/plugins.moby exec --tty $PLUGID bash</code></pre>
<p>Also you can use curl to check the plugin socket connectivity:</p>
<pre class="console"><code>docker plugin list --no-trunc
PLUGID=123abc...
sudo curl -H Content-Type:application/json -XPOST -d {} --unix-socket /run/docker/plugins/$PLUGID/rclone.sock http://localhost/Plugin.Activate</code></pre>
<p>though this is rarely needed.</p>
<p>If the plugin fails to work properly, and only as a last resort after
you tried diagnosing with the above methods, you can try clearing the
state of the plugin. <strong>Note that all existing rclone docker
volumes will probably have to be recreated.</strong> This might be
needed because a reinstall don't cleanup existing state files to allow
for easy restoration, as stated above.</p>
<pre class="console"><code>docker plugin disable rclone # disable the plugin to ensure no interference
sudo rm /var/lib/docker-plugins/rclone/cache/docker-plugin.state # removing the plugin state
docker plugin enable rclone # re-enable the plugin afterward</code></pre>
<h2 id="caveats">Caveats</h2>
<p>Finally I'd like to mention a <em>caveat with updating volume
settings</em>. Docker CLI does not have a dedicated command like
<code>docker volume update</code>. It may be tempting to invoke
<code>docker volume create</code> with updated options on existing
volume, but there is a gotcha. The command will do nothing, it won't
even return an error. I hope that docker maintainers will fix this some
day. In the meantime be aware that you must remove your volume before
recreating it with new settings:</p>
<pre class="console"><code>docker volume remove my_vol
docker volume create my_vol -d rclone -o opt1=new_val1 ...</code></pre>
<p>and verify that settings did update:</p>
<pre class="console"><code>docker volume list
docker volume inspect my_vol</code></pre>
<p>If docker refuses to remove the volume, you should find containers or
swarm services that use it and stop them first.</p>
<h2 id="bisync">Bisync</h2>
<p><code>bisync</code> is considered an <strong>advanced
command</strong>, so use with care. Make sure you have read and
understood the entire <a href="https://rclone.org/bisync">manual</a>
(especially the <a href="#limitations">Limitations</a> section) before
using, or data loss can result. Questions can be asked in the <a
href="https://forum.rclone.org/">Rclone Forum</a>.</p>
<h2 id="getting-started">Getting started</h2>
<ul>
<li><a href="https://rclone.org/install/">Install rclone</a> and setup
your remotes.</li>
<li>Bisync will create its working directory at
<code>~/.cache/rclone/bisync</code> on Linux,
<code>/Users/yourusername/Library/Caches/rclone/bisync</code> on Mac, or
<code>C:\Users\MyLogin\AppData\Local\rclone\bisync</code> on Windows.
Make sure that this location is writable.</li>
<li>Run bisync with the <code>--resync</code> flag, specifying the paths
to the local and remote sync directory roots.</li>
<li>For successive sync runs, leave off the <code>--resync</code> flag.
(<strong>Important!</strong>)</li>
<li>Consider using a <a href="#filtering">filters file</a> for excluding
unnecessary files and directories from the sync.</li>
<li>Consider setting up the <a href="#check-access">--check-access</a>
feature for safety.</li>
<li>On Linux or Mac, consider setting up a <a href="#cron">crontab
entry</a>. bisync can safely run in concurrent cron jobs thanks to lock
files it maintains.</li>
</ul>
<p>For example, your first command might look like this:</p>
<pre class="console"><code>rclone bisync remote1:path1 remote2:path2 --create-empty-src-dirs --compare size,modtime,checksum --slow-hash-sync-only --resilient -MvP --drive-skip-gdocs --fix-case --resync --dry-run</code></pre>
<p>If all looks good, run it again without <code>--dry-run</code>. After
that, remove <code>--resync</code> as well.</p>
<p>Here is a typical run log (with timestamps removed for clarity):</p>
<pre class="console"><code>rclone bisync /testdir/path1/ /testdir/path2/ --verbose

      --download-hash                        Compute hash by downloading when otherwise unavailable. (warning: may be slow and use lots of data!)
      --filters-file string                  Read filtering patterns from a file
      --force                                Bypass --max-delete safety check and run the sync. Consider using with --verbose
  -h, --help                                 help for bisync
      --ignore-listing-checksum              Do not use checksums for listings (add --ignore-checksum to additionally skip post-copy checksum checks)
      --max-lock Duration                    Consider lock files older than this to be expired (default: 0 (never expire)) (minimum: 2m) (default 0s)
      --no-cleanup                           Retain working files (useful for troubleshooting and testing).
      --no-slow-hash                         Ignore listing checksums only on backends where they are slow
      --recover                              Automatically recover from interruptions without requiring --resync.
      --remove-empty-dirs                    Remove ALL empty directories at the final cleanup step.
      --resilient                            Allow future runs to retry after certain less-serious errors, instead of requiring --resync.
  -1, --resync                               Performs the resync run. Equivalent to --resync-mode path1. Consider using --verbose or --dry-run first.
      --resync-mode string                   During resync, prefer the version that is: path1, path2, newer, older, larger, smaller (default: path1 if --resync, otherwise none for no resync.) (default &quot;none&quot;)
      --retries int                          Retry operations this many times if they fail (requires --resilient). (default 3)
      --retries-sleep Duration               Interval between retrying operations if they fail, e.g. 500ms, 60s, 5m (0 to disable) (default 0s)
      --slow-hash-sync-only                  Ignore slow checksums for listings and deltas, but still consider them during sync calls.
      --workdir string                       Use custom working dir - useful for testing. (default: {WORKDIR})
      --max-delete PERCENT                   Safety check on maximum percentage of deleted files allowed. If exceeded, the bisync run will abort. (default: 50%)
  -n, --dry-run                              Go through the motions - No files are copied/deleted.
  -v, --verbose                              Increases logging verbosity. May be specified more than once for more details.</code></pre>
<p>Arbitrary rclone flags may be specified on the <a
href="https://rclone.org/commands/rclone_bisync/">bisync command
line</a>, for example
<code>rclone bisync ./testdir/path1/ gdrive:testdir/path2/ --drive-skip-gdocs -v -v --timeout 10s</code>
Note that interactions of various rclone flags with bisync process flow
has not been fully tested yet.</p>
<h3 id="paths">Paths</h3>
<p>Path1 and Path2 arguments may be references to any mix of local
directory paths (absolute or relative), UNC paths
(<code>//server/share/path</code>), Windows drive paths (with a drive
letter and <code>:</code>) or configured <a
href="https://rclone.org/docs/#syntax-of-remote-paths">remotes</a> with
optional subdirectory paths. Cloud references are distinguished by
having a <code>:</code> in the argument (see <a href="#windows">Windows
support</a> below).</p>
<p>Path1 and Path2 are treated equally, in that neither has priority for
file changes (except during <a
href="#resync"><code>--resync</code></a>), and access efficiency does
not change whether a remote is on Path1 or Path2.</p>
<p>The listings in bisync working directory (default:
<code>~/.cache/rclone/bisync</code>) are named based on the Path1 and
Path2 arguments so that separate syncs to individual directories within
the tree may be set up, e.g.:
<code>path_to_local_tree..dropbox_subdir.lst</code>.</p>
<p>Any empty directories after the sync on both the Path1 and Path2
filesystems are not deleted by default, unless
<code>--create-empty-src-dirs</code> is specified. If the
<code>--remove-empty-dirs</code> flag is specified, then both paths will
have ALL empty directories purged as the last step in the process.</p>
<h2 id="command-line-flags">Command-line flags</h2>
<h3 id="resync">--resync</h3>
<p>This will effectively make both Path1 and Path2 filesystems contain a
matching superset of all files. By default, Path2 files that do not
exist in Path1 will be copied to Path1, and the process will then copy
the Path1 tree to Path2.</p>
<p>The <code>--resync</code> sequence is roughly equivalent to the
following (but see <a href="#resync-mode"><code>--resync-mode</code></a>
for other options):</p>
<pre class="console"><code>rclone copy Path2 Path1 --ignore-existing [--create-empty-src-dirs]
rclone copy Path1 Path2 [--create-empty-src-dirs]</code></pre>
<p>The base directories on both Path1 and Path2 filesystems must exist
or bisync will fail. This is required for safety - that bisync can
verify that both paths are valid.</p>
<p>When using <code>--resync</code>, a newer version of a file on the
Path2 filesystem will (by default) be overwritten by the Path1
filesystem version. (Note that this is <a
href="https://github.com/rclone/rclone/issues/5681#issuecomment-938761815">NOT
entirely symmetrical</a>, and more symmetrical options can be specified
with the <a href="#resync-mode"><code>--resync-mode</code></a> flag.)
Carefully evaluate deltas using <a
href="https://rclone.org/flags/#non-backend-flags">--dry-run</a>.</p>
<p>For a resync run, one of the paths may be empty (no files in the path
tree). The resync run should result in files on both paths, else a
normal non-resync run will fail.</p>
<p>For a non-resync run, either path being empty (no files in the tree)
fails with
<code>Empty current PathN listing. Cannot sync to an empty directory: X.pathN.lst</code>
This is a safety check that an unexpected empty path does not result in
deleting <strong>everything</strong> in the other path.</p>
<p>Note that <code>--resync</code> implies
<code>--resync-mode path1</code> unless a different <a
href="#resync-mode"><code>--resync-mode</code></a> is explicitly
specified. It is not necessary to use both the <code>--resync</code> and
<code>--resync-mode</code> flags -- either one is sufficient without the
other.</p>
<p><strong>Note:</strong> <code>--resync</code> (including
<code>--resync-mode</code>) should only be used under three specific
(rare) circumstances:</p>
<ol type="1">
<li>It is your <em>first</em> bisync run (between these two paths)</li>
<li>You've just made changes to your bisync settings (such as editing
the contents of your <code>--filters-file</code>)</li>
<li>There was an error on the prior run, and as a result, bisync now
requires <code>--resync</code> to recover</li>
</ol>
<p>The rest of the time, you should <em>omit</em> <code>--resync</code>.
The reason is because <code>--resync</code> will only <em>copy</em> (not
<em>sync</em>) each side to the other. Therefore, if you included
<code>--resync</code> for every bisync run, it would never be possible
to delete a file -- the deleted file would always keep reappearing at
the end of every run (because it's being copied from the other side
where it still exists). Similarly, renaming a file would always result
in a duplicate copy (both old and new name) on both sides.</p>
<p>If you find that frequent interruptions from #3 are an issue, rather
than automatically running <code>--resync</code>, the recommended
alternative is to use the <a
href="#resilient"><code>--resilient</code></a>, <a
href="#recover"><code>--recover</code></a>, and <a
href="#conflict-resolve"><code>--conflict-resolve</code></a> flags,
(along with <a href="#graceful-shutdown">Graceful Shutdown</a> mode,
when needed) for a very robust "set-it-and-forget-it" bisync setup that
can automatically bounce back from almost any interruption it might
encounter. Consider adding something like the following:</p>
<pre class="text"><code>--resilient --recover --max-lock 2m --conflict-resolve newer</code></pre>
<h3 id="resync-mode">--resync-mode CHOICE</h3>
<p>In the event that a file differs on both sides during a
<code>--resync</code>, <code>--resync-mode</code> controls which version
will overwrite the other. The supported options are similar to <a
href="#conflict-resolve"><code>--conflict-resolve</code></a>. For all of
the following options, the version that is kept is referred to as the
"winner", and the version that is overwritten (deleted) is referred to
as the "loser". The options are named after the "winner":</p>
<ul>
<li><code>path1</code> - (the default) - the version from Path1 is
unconditionally considered the winner (regardless of
<code>modtime</code> and <code>size</code>, if any). This can be useful
if one side is more trusted or up-to-date than the other, at the time of
the <code>--resync</code>.</li>
<li><code>path2</code> - same as <code>path1</code>, except the path2
version is considered the winner.</li>
<li><code>newer</code> - the newer file (by <code>modtime</code>) is
considered the winner, regardless of which side it came from. This may
result in having a mix of some winners from Path1, and some winners from
Path2. (The implementation is analogous to running
<code>rclone copy --update</code> in both directions.)</li>
<li><code>older</code> - same as <code>newer</code>, except the older
file is considered the winner, and the newer file is considered the
loser.</li>
<li><code>larger</code> - the larger file (by <code>size</code>) is
considered the winner (regardless of <code>modtime</code>, if any). This
can be a useful option for remotes without <code>modtime</code> support,
or with the kinds of files (such as logs) that tend to grow but not
shrink, over time.</li>
<li><code>smaller</code> - the smaller file (by <code>size</code>) is
considered the winner (regardless of <code>modtime</code>, if any).</li>
</ul>
<p>For all of the above options, note the following:</p>
<ul>
<li>If either of the underlying remotes lacks support for the chosen
method, it will be ignored and will fall back to the default of
<code>path1</code>. (For example, if <code>--resync-mode newer</code> is
set, but one of the paths uses a remote that doesn't support
<code>modtime</code>.)</li>
<li>If a winner can't be determined because the chosen method's
attribute is missing or equal, it will be ignored, and bisync will
instead try to determine whether the files differ by looking at the
other <code>--compare</code> methods in effect. (For example, if
<code>--resync-mode newer</code> is set, but the Path1 and Path2
modtimes are identical, bisync will compare the sizes.) If bisync
concludes that they differ, preference is given to whichever is the
"source" at that moment. (In practice, this gives a slight advantage to
Path2, as the 2to1 copy comes before the 1to2 copy.) If the files <em>do
not</em> differ, nothing is copied (as both sides are already
correct).</li>
<li>These options apply only to files that exist on both sides (with the
same name and relative path). Files that exist <em>only</em> on one side
and not the other are <em>always</em> copied to the other, during
<code>--resync</code> (this is one of the main differences between
resync and non-resync runs.).</li>
<li><code>--conflict-resolve</code>, <code>--conflict-loser</code>, and
<code>--conflict-suffix</code> do not apply during
<code>--resync</code>, and unlike these flags, nothing is renamed during
<code>--resync</code>. When a file differs on both sides during
<code>--resync</code>, one version always overwrites the other (much
like in <code>rclone copy</code>.) (Consider using <a
href="#backup-dir1-and-backup-dir2"><code>--backup-dir</code></a> to
retain a backup of the losing version.)</li>
<li>Unlike for <code>--conflict-resolve</code>,
<code>--resync-mode none</code> is not a valid option (or rather, it
will be interpreted as "no resync", unless <code>--resync</code> has
also been specified, in which case it will be ignored.)</li>
<li>Winners and losers are decided at the individual file-level only
(there is not currently an option to pick an entire winning directory
atomically, although the <code>path1</code> and <code>path2</code>
options typically produce a similar result.)</li>
<li>To maintain backward-compatibility, the <code>--resync</code> flag
implies <code>--resync-mode path1</code> unless a different
<code>--resync-mode</code> is explicitly specified. Similarly, all
<code>--resync-mode</code> options (except <code>none</code>) imply
<code>--resync</code>, so it is not necessary to use both the
<code>--resync</code> and <code>--resync-mode</code> flags
simultaneously -- either one is sufficient without the other.</li>
</ul>
<h3 id="check-access">--check-access</h3>
<p>Access check files are an additional safety measure against data
loss. bisync will ensure it can find matching <code>RCLONE_TEST</code>
files in the same places in the Path1 and Path2 filesystems.
<code>RCLONE_TEST</code> files are not generated automatically. For
<code>--check-access</code> to succeed, you must first either:
<strong>A)</strong> Place one or more <code>RCLONE_TEST</code> files in
both systems, or <strong>B)</strong> Set <code>--check-filename</code>
to a filename already in use in various locations throughout your sync'd
fileset. Recommended methods for <strong>A)</strong> include:</p>
<ul>
<li><code>rclone touch Path1/RCLONE_TEST</code> (create a new file)</li>
<li><code>rclone copyto Path1/RCLONE_TEST Path2/RCLONE_TEST</code> (copy
an existing file)</li>
<li><code>rclone copy Path1/RCLONE_TEST Path2/RCLONE_TEST  --include "RCLONE_TEST"</code>
(copy multiple files at once, recursively)</li>
<li>create the files manually (outside of rclone)</li>
<li>run <code>bisync</code> once <em>without</em>
<code>--check-access</code> to set matching files on both filesystems
will also work, but is not preferred, due to potential for user error
(you are temporarily disabling the safety feature).</li>
</ul>
<p>Note that <code>--check-access</code> is still enforced on
<code>--resync</code>, so <code>bisync --resync --check-access</code>
will not work as a method of initially setting the files (this is to
ensure that bisync can't <a
href="https://forum.rclone.org/t/bisync-bugs-and-feature-requests/37636#:~:text=3.%20%2D%2Dcheck%2Daccess%20doesn%27t%20always%20fail%20when%20it%20should">inadvertently
circumvent its own safety switch</a>.)</p>
<p>Time stamps and file contents for <code>RCLONE_TEST</code> files are
not important, just the names and locations. If you have symbolic links
in your sync tree it is recommended to place <code>RCLONE_TEST</code>
files in the linked-to directory tree to protect against bisync assuming
a bunch of deleted files if the linked-to tree should not be accessible.
See also the <a href="--check-filename">--check-filename</a> flag.</p>
<h3 id="check-filename">--check-filename</h3>
<p>Name of the file(s) used in access health validation. The default
<code>--check-filename</code> is <code>RCLONE_TEST</code>. One or more
files having this filename must exist, synchronized between your source
and destination filesets, in order for <code>--check-access</code> to
succeed. See <a href="#check-access">--check-access</a> for additional
details.</p>
<h3 id="compare">--compare</h3>
<p>As of <code>v1.66</code>, bisync fully supports comparing based on
any combination of size, modtime, and checksum (lifting the prior
restriction on backends without modtime support.)</p>
<p>By default (without the <code>--compare</code> flag), bisync inherits
the same comparison options as <code>sync</code> (that is:
<code>size</code> and <code>modtime</code> by default, unless modified
with flags such as <a
href="https://rclone.org/docs/#c-checksum"><code>--checksum</code></a>
or <a href="/docs/#size-only"><code>--size-only</code></a>.)</p>
<p>If the <code>--compare</code> flag is set, it will override these
defaults. This can be useful if you wish to compare based on
combinations not currently supported in <code>sync</code>, such as
comparing all three of <code>size</code> AND <code>modtime</code> AND
<code>checksum</code> simultaneously (or just <code>modtime</code> AND
<code>checksum</code>).</p>
<p><code>--compare</code> takes a comma-separated list, with the
currently supported values being <code>size</code>,
<code>modtime</code>, and <code>checksum</code>. For example, if you
want to compare size and checksum, but not modtime, you would do:</p>
<pre class="text"><code>--compare size,checksum</code></pre>
<p>Or if you want to compare all three:</p>
<pre class="text"><code>--compare size,modtime,checksum</code></pre>
<p><code>--compare</code> overrides any conflicting flags. For example,
if you set the conflicting flags
<code>--compare checksum --size-only</code>, <code>--size-only</code>
will be ignored, and bisync will compare checksum and not size. To avoid
confusion, it is recommended to use <em>either</em>
<code>--compare</code> or the normal <code>sync</code> flags, but not
both.</p>
<p>If <code>--compare</code> includes <code>checksum</code> and both
remotes support checksums but have no hash types in common with each
other, checksums will be considered <em>only</em> for comparisons within
the same side (to determine what has changed since the prior sync), but
not for comparisons against the opposite side. If one side supports
checksums and the other does not, checksums will only be considered on
the side that supports them.</p>
<p>When comparing with <code>checksum</code> and/or <code>size</code>
without <code>modtime</code>, bisync cannot determine whether a file is
<code>newer</code> or <code>older</code> -- only whether it is
<code>changed</code> or <code>unchanged</code>. (If it is
<code>changed</code> on both sides, bisync still does the standard
equality-check to avoid declaring a sync conflict unless it absolutely
has to.)</p>
<p>It is recommended to do a <code>--resync</code> when changing
<code>--compare</code> settings, as otherwise your prior listing files
may not contain the attributes you wish to compare (for example, they
will not have stored checksums if you were not previously comparing
checksums.)</p>
<h3 id="ignore-listing-checksum">--ignore-listing-checksum</h3>
<p>When <code>--checksum</code> or <code>--compare checksum</code> is
set, bisync will retrieve (or generate) checksums (for backends that
support them) when creating the listings for both paths, and store the
checksums in the listing files. <code>--ignore-listing-checksum</code>
will disable this behavior, which may speed things up considerably,
especially on backends (such as <a
href="https://rclone.org/local/">local</a>) where hashes must be
computed on the fly instead of retrieved. Please note the following:</p>
<ul>
<li>As of <code>v1.66</code>, <code>--ignore-listing-checksum</code> is
now automatically set when neither <code>--checksum</code> nor
<code>--compare checksum</code> are in use (as the checksums would not
be used for anything.)</li>
<li><code>--ignore-listing-checksum</code> is NOT the same as <a
href="https://rclone.org/docs/#ignore-checksum"><code>--ignore-checksum</code></a>,
and you may wish to use one or the other, or both. In a nutshell:
<code>--ignore-listing-checksum</code> controls whether checksums are
considered when scanning for diffs, while <code>--ignore-checksum</code>
controls whether checksums are considered during the copy/sync
operations that follow, if there ARE diffs.</li>
<li>Unless <code>--ignore-listing-checksum</code> is passed, bisync
currently computes hashes for one path <em>even when there's no common
hash with the other path</em> (for example, a <a
href="https://rclone.org/crypt/#modification-times-and-hashes">crypt</a>
remote.) This can still be beneficial, as the hashes will still be used
to detect changes within the same side (if <code>--checksum</code> or
<code>--compare checksum</code> is set), even if they can't be used to
compare against the opposite side.</li>
<li>If you wish to ignore listing checksums <em>only</em> on remotes
where they are slow to compute, consider using <a
href="#no-slow-hash"><code>--no-slow-hash</code></a> (or <a
href="#slow-hash-sync-only"><code>--slow-hash-sync-only</code></a>)
instead of <code>--ignore-listing-checksum</code>.</li>
<li>If <code>--ignore-listing-checksum</code> is used simultaneously
with <code>--compare checksum</code> (or <code>--checksum</code>),
checksums will be ignored for bisync deltas, but still considered during
the sync operations that follow (if deltas are detected based on modtime
and/or size.)</li>
</ul>
<h3 id="no-slow-hash">--no-slow-hash</h3>
<p>On some remotes (notably <code>local</code>), checksums can
dramatically slow down a bisync run, because hashes cannot be stored and
need to be computed in real-time when they are requested. On other
remotes (such as <code>drive</code>), they add practically no time at
all. The <code>--no-slow-hash</code> flag will automatically skip
checksums on remotes where they are slow, while still comparing them on
others (assuming <a href="#compare"><code>--compare</code></a> includes
<code>checksum</code>.) This can be useful when one of your bisync paths
is slow but you still want to check checksums on the other, for a more
robust sync.</p>
<h3 id="slow-hash-sync-only">--slow-hash-sync-only</h3>
<p>Same as <a href="#no-slow-hash"><code>--no-slow-hash</code></a>,
except slow hashes are still considered during sync calls. They are
still NOT considered for determining deltas, nor or they included in
listings. They are also skipped during <code>--resync</code>. The main
use case for this flag is when you have a large number of files, but
relatively few of them change from run to run -- so you don't want to
check your entire tree every time (it would take too long), but you
still want to consider checksums for the smaller group of files for
which a <code>modtime</code> or <code>size</code> change was detected.
Keep in mind that this speed savings comes with a safety trade-off: if a
file's content were to change without a change to its
<code>modtime</code> or <code>size</code>, bisync would not detect it,
and it would not be synced.</p>
<p><code>--slow-hash-sync-only</code> is only useful if both remotes
share a common hash type (if they don't, bisync will automatically fall
back to <code>--no-slow-hash</code>.) Both <code>--no-slow-hash</code>
and <code>--slow-hash-sync-only</code> have no effect without
<code>--compare checksum</code> (or <code>--checksum</code>).</p>
<h3 id="download-hash">--download-hash</h3>
<p>If <code>--download-hash</code> is set, bisync will use best efforts
to obtain an MD5 checksum by downloading and computing on-the-fly, when
checksums are not otherwise available (for example, a remote that
doesn't support them.) Note that since rclone has to download the entire
file, this may dramatically slow down your bisync runs, and is also
likely to use a lot of data, so it is probably not practical for bisync
paths with a large total file size. However, it can be a good option for
syncing small-but-important files with maximum accuracy (for example, a
source code repo on a <code>crypt</code> remote.) An additional
advantage over methods like <a
href="https://rclone.org/commands/rclone_cryptcheck/"><code>cryptcheck</code></a>
is that the original file is not required for comparison (for example,
<code>--download-hash</code> can be used to bisync two different crypt
remotes with different passwords.)</p>
<p>When <code>--download-hash</code> is set, bisync still looks for more
efficient checksums first, and falls back to downloading only when none
are found. It takes priority over conflicting flags such as
<code>--no-slow-hash</code>. <code>--download-hash</code> is not
suitable for <a href="#gdocs">Google Docs</a> and other files of unknown
size, as their checksums would change from run to run (due to small
variances in the internals of the generated export file.) Therefore,
bisync automatically skips <code>--download-hash</code> for files with a
size less than 0.</p>

href="https://rclone.org/hasher/"><code>Hasher</code></a> backend, <a

command</p>
<h3 id="max-delete">--max-delete</h3>
<p>As a safety check, if greater than the <code>--max-delete</code>
percent of files were deleted on either the Path1 or Path2 filesystem,
then bisync will abort with a warning message, without making any
changes. The default <code>--max-delete</code> is <code>50%</code>. One
way to trigger this limit is to rename a directory that contains more
than half of your files. This will appear to bisync as a bunch of
deleted files and a bunch of new files. This safety check is intended to
block bisync from deleting all of the files on both filesystems due to a
temporary network access issue, or if the user had inadvertently deleted
the files on one side or the other. To force the sync, either set a
different delete percentage limit, e.g. <code>--max-delete 75</code>
(allows up to 75% deletion), or use <code>--force</code> to bypass the
check.</p>
<p>Also see the <a href="#all-files-changed">all files changed</a>
check.</p>
<h3 id="filters-file">--filters-file</h3>
<p>By using rclone filter features you can exclude file types or
directory sub-trees from the sync. See the <a href="#filtering">bisync
filters</a> section and generic <a
href="https://rclone.org/filtering/#filter-from-read-filtering-patterns-from-a-file">--filter-from</a>
documentation. An <a href="#example-filters-file">example filters
file</a> contains filters for non-allowed files for syncing with
Dropbox.</p>
<p>If you make changes to your filters file then bisync requires a run
with <code>--resync</code>. This is a safety feature, which prevents
existing files on the Path1 and/or Path2 side from seeming to disappear
from view (since they are excluded in the new listings), which would
fool bisync into seeing them as deleted (as compared to the prior run
listings), and then bisync would proceed to delete them for real.</p>
<p>To block this from happening, bisync calculates an MD5 hash of the
filters file and stores the hash in a <code>.md5</code> file in the same
place as your filters file. On the next run with
<code>--filters-file</code> set, bisync re-calculates the MD5 hash of
the current filters file and compares it to the hash stored in the
<code>.md5</code> file. If they don't match, the run aborts with a
critical error and thus forces you to do a <code>--resync</code>, likely
avoiding a disaster.</p>
<h3 id="conflict-resolve">--conflict-resolve CHOICE</h3>
<p>In bisync, a "conflict" is a file that is <em>new</em> or
<em>changed</em> on <em>both sides</em> (relative to the prior run) AND
is <em>not currently identical</em> on both sides.
<code>--conflict-resolve</code> controls how bisync handles such a
scenario. The currently supported options are:</p>
<ul>
<li><code>none</code> - (the default) - do not attempt to pick a winner,
keep and rename both files according to <a
href="#conflict-loser"><code>--conflict-loser</code></a> and <a
href="#conflict-suffix"><code>--conflict-suffix</code></a> settings. For
example, with the default settings, <code>file.txt</code> on Path1 is
renamed <code>file.txt.conflict1</code> and <code>file.txt</code> on
Path2 is renamed <code>file.txt.conflict2</code>. Both are copied to the
opposite path during the run, so both sides end up with a copy of both
files. (As <code>none</code> is the default, it is not necessary to
specify <code>--conflict-resolve none</code> -- you can just omit the
flag.)</li>
<li><code>newer</code> - the newer file (by <code>modtime</code>) is
considered the winner and is copied without renaming. The older file
(the "loser") is handled according to <code>--conflict-loser</code> and
<code>--conflict-suffix</code> settings (either renamed or deleted.) For
example, if <code>file.txt</code> on Path1 is newer than
<code>file.txt</code> on Path2, the result on both sides (with other
default settings) will be <code>file.txt</code> (winner from Path1) and
<code>file.txt.conflict1</code> (loser from Path2).</li>
<li><code>older</code> - same as <code>newer</code>, except the older
file is considered the winner, and the newer file is considered the
loser.</li>
<li><code>larger</code> - the larger file (by <code>size</code>) is
considered the winner (regardless of <code>modtime</code>, if any).</li>
<li><code>smaller</code> - the smaller file (by <code>size</code>) is
considered the winner (regardless of <code>modtime</code>, if any).</li>
<li><code>path1</code> - the version from Path1 is unconditionally
considered the winner (regardless of <code>modtime</code> and
<code>size</code>, if any). This can be useful if one side is usually
more trusted or up-to-date than the other.</li>
<li><code>path2</code> - same as <code>path1</code>, except the path2
version is considered the winner.</li>
</ul>
<p>For all of the above options, note the following:</p>
<ul>
<li>If either of the underlying remotes lacks support for the chosen
method, it will be ignored and fall back to <code>none</code>. (For
example, if <code>--conflict-resolve newer</code> is set, but one of the
paths uses a remote that doesn't support <code>modtime</code>.)</li>
<li>If a winner can't be determined because the chosen method's
attribute is missing or equal, it will be ignored and fall back to
<code>none</code>. (For example, if
<code>--conflict-resolve newer</code> is set, but the Path1 and Path2
modtimes are identical, even if the sizes may differ.)</li>
<li>If the file's content is currently identical on both sides, it is
not considered a "conflict", even if new or changed on both sides since
the prior sync. (For example, if you made a change on one side and then
synced it to the other side by other means.) Therefore, none of the
conflict resolution flags apply in this scenario.</li>
<li>The conflict resolution flags do not apply during a
<code>--resync</code>, as there is no "prior run" to speak of (but see
<a href="#resync-mode"><code>--resync-mode</code></a> for similar
options.)</li>
</ul>
<h3 id="conflict-loser">--conflict-loser CHOICE</h3>
<p><code>--conflict-loser</code> determines what happens to the "loser"
of a sync conflict (when <a
href="#conflict-resolve"><code>--conflict-resolve</code></a> determines
a winner) or to both files (when there is no winner.) The currently
supported options are:</p>
<ul>
<li><code>num</code> - (the default) - auto-number the conflicts by
automatically appending the next available number to the
<code>--conflict-suffix</code>, in chronological order. For example,
with the default settings, the first conflict for <code>file.txt</code>
will be renamed <code>file.txt.conflict1</code>. If
<code>file.txt.conflict1</code> already exists,
<code>file.txt.conflict2</code> will be used instead (etc., up to a
maximum of 9223372036854775807 conflicts.)</li>
<li><code>pathname</code> - rename the conflicts according to which side
they came from, which was the default behavior prior to
<code>v1.66</code>. For example, with
<code>--conflict-suffix path</code>, <code>file.txt</code> from Path1
will be renamed <code>file.txt.path1</code>, and <code>file.txt</code>
from Path2 will be renamed <code>file.txt.path2</code>. If two
non-identical suffixes are provided (ex.
<code>--conflict-suffix cloud,local</code>), the trailing digit is
omitted. Importantly, note that with <code>pathname</code>, there is no
auto-numbering beyond <code>2</code>, so if <code>file.txt.path2</code>
somehow already exists, it will be overwritten. Using a dynamic date
variable in your <code>--conflict-suffix</code> (see below) is one
possible way to avoid this. Note also that conflicts-of-conflicts are
possible, if the original conflict is not manually resolved -- for
example, if for some reason you edited <code>file.txt.path1</code> on
both sides, and those edits were different, the result would be
<code>file.txt.path1.path1</code> and <code>file.txt.path1.path2</code>
(in addition to <code>file.txt.path2</code>.)</li>
<li><code>delete</code> - keep the winner only and delete the loser,
instead of renaming it. If a winner cannot be determined (see
<code>--conflict-resolve</code> for details on how this could happen),
<code>delete</code> is ignored and the default <code>num</code> is used
instead (i.e. both versions are kept and renamed, and neither is
deleted.) <code>delete</code> is inherently the most destructive option,
so use it only with care.</li>
</ul>
<p>For all of the above options, note that if a winner cannot be
determined (see <code>--conflict-resolve</code> for details on how this
could happen), or if <code>--conflict-resolve</code> is not in use,
<em>both</em> files will be renamed.</p>
<h3 id="conflict-suffix">--conflict-suffix STRING[,STRING]</h3>
<p><code>--conflict-suffix</code> controls the suffix that is appended
when bisync renames a <a
href="#conflict-loser"><code>--conflict-loser</code></a> (default:
<code>conflict</code>). <code>--conflict-suffix</code> will accept
either one string or two comma-separated strings to assign different
suffixes to Path1 vs. Path2. This may be helpful later in identifying
the source of the conflict. (For example,
<code>--conflict-suffix dropboxconflict,laptopconflict</code>)</p>
<p>With <code>--conflict-loser num</code>, a number is always appended
to the suffix. With <code>--conflict-loser pathname</code>, a number is
appended only when one suffix is specified (or when two identical
suffixes are specified.) i.e. with
<code>--conflict-loser pathname</code>, all of the following would
produce exactly the same result:</p>
<pre class="text"><code>--conflict-suffix path
--conflict-suffix path,path
--conflict-suffix path1,path2</code></pre>
<p>Suffixes may be as short as 1 character. By default, the suffix is
appended after any other extensions (ex.
<code>file.jpg.conflict1</code>), however, this can be changed with the
<a
href="https://rclone.org/docs/#suffix-keep-extension"><code>--suffix-keep-extension</code></a>
flag (i.e. to instead result in <code>file.conflict1.jpg</code>).</p>
<p><code>--conflict-suffix</code> supports several <em>dynamic date
variables</em> when enclosed in curly braces as globs. This can be
helpful to track the date and/or time that each conflict was handled by
bisync. For example:</p>
<pre class="text"><code>--conflict-suffix {DateOnly}-conflict
// result: myfile.txt.2006-01-02-conflict1</code></pre>
<p>All of the formats described <a
href="https://pkg.go.dev/time#pkg-constants">here (go Time.Layout
constants)</a> and <a
href="https://pkg.go.dev/time#example-Time.Format">here (go Time.Format
examples)</a> are supported, but take care to ensure that your chosen
format does not use any characters that are illegal on your remotes (for
example, macOS does not allow colons in filenames, and slashes are also
best avoided as they are often interpreted as directory separators.) To
address this particular issue, an additional
<code>{MacFriendlyTime}</code> (or just <code>{mac}</code>) option is
supported, which results in <code>2006-01-02 0304PM</code>.</p>
<p>Note that <code>--conflict-suffix</code> is entirely separate from
rclone's main <a
href="https://rclone.org/docs/#suffix-string"><code>--sufix</code></a>
flag. This is intentional, as users may wish to use both flags
simultaneously, if also using <a
href="#backup-dir1-and-backup-dir2"><code>--backup-dir</code></a>.</p>
<p>Finally, note that the default in bisync prior to <code>v1.66</code>
was to rename conflicts with <code>..path1</code> and
<code>..path2</code> (with two periods, and <code>path</code> instead of
<code>conflict</code>.) Bisync now defaults to a single dot instead of a
double dot, but additional dots can be added by including them in the
specified suffix string. For example, for behavior equivalent to the
previous default, use:</p>
<pre class="text"><code>[--conflict-resolve none] --conflict-loser pathname --conflict-suffix .path</code></pre>
<h3 id="check-sync">--check-sync</h3>
<p>Enabled by default, the check-sync function checks that all of the
same files exist in both the Path1 and Path2 history listings. This
<em>check-sync</em> integrity check is performed at the end of the sync
run by default. Any untrapped failing copy/deletes between the two paths
might result in differences between the two listings and in the
untracked file content differences between the two paths. A resync run
would correct the error.</p>
<p>Note that the default-enabled integrity check locally executes a load
of both the final Path1 and Path2 listings, and thus adds to the run
time of a sync. Using <code>--check-sync=false</code> will disable it
and may significantly reduce the sync run times for very large numbers
of files.</p>
<p>The check may be run manually with <code>--check-sync=only</code>. It
runs only the integrity check and terminates without actually
syncing.</p>
<p>Note that currently, <code>--check-sync</code> <strong>only checks
listing snapshots and NOT the actual files on the remotes.</strong> Note
also that the listing snapshots will not know about any changes that
happened during or after the latest bisync run, as those will be
discovered on the next run. Therefore, while listings should always
match <em>each other</em> at the end of a bisync run, it is
<em>expected</em> that they will not match the underlying remotes, nor
will the remotes match each other, if there were changes during or after
the run. This is normal, and any differences will be detected and synced
on the next run.</p>
<p>For a robust integrity check of the current state of the remotes (as
opposed to just their listing snapshots), consider using <a
href="commands/rclone_check/"><code>check</code></a> (or <a
href="https://rclone.org/commands/rclone_cryptcheck/"><code>cryptcheck</code></a>,
if at least one path is a <code>crypt</code> remote) instead of
<code>--check-sync</code>, keeping in mind that differences are expected
if files changed during or after your last bisync run.</p>
<p>For example, a possible sequence could look like this:</p>
<ol type="1">
<li><p>Normally scheduled bisync run:</p>
<pre class="console"><code>rclone bisync Path1 Path2 -MPc --check-access --max-delete 10 --filters-file /path/to/filters.txt -v --no-cleanup --ignore-listing-checksum --disable ListR --checkers=16 --drive-pacer-min-sleep=10ms --create-empty-src-dirs --resilient</code></pre></li>
<li><p>Periodic independent integrity check (perhaps scheduled nightly
or weekly):</p>
<pre class="console"><code>rclone check -MvPc Path1 Path2 --filter-from /path/to/filters.txt</code></pre></li>
<li><p>If diffs are found, you have some choices to correct them. If one
side is more up-to-date and you want to make the other side match it,
you could run:</p>
<pre class="console"><code>rclone sync Path1 Path2 --filter-from /path/to/filters.txt --create-empty-src-dirs -MPc -v</code></pre></li>
</ol>
<p>(or switch Path1 and Path2 to make Path2 the source-of-truth)</p>
<p>Or, if neither side is totally up-to-date, you could run a
<code>--resync</code> to bring them back into agreement (but remember
that this could cause deleted files to re-appear.)</p>
<p>*Note also that <code>rclone check</code> does not currently include
empty directories, so if you want to know if any empty directories are
out of sync, consider alternatively running the above
<code>rclone sync</code> command with <code>--dry-run</code> added.</p>

modifications</a>, <a href="#resilient"><code>--resilient</code></a></p>
<h3 id="resilient">--resilient</h3>
<p>By default, most errors or interruptions will cause bisync to abort
and require <a href="#resync"><code>--resync</code></a> to recover. This
is a safety feature, to prevent bisync from running again until a user
checks things out. However, in some cases, bisync can go too far and
enforce a lockout when one isn't actually necessary, like for certain
less-serious errors that might resolve themselves on the next run. When
<code>--resilient</code> is specified, bisync tries its best to recover
and self-correct, and only requires <code>--resync</code> as a last
resort when a human's involvement is absolutely necessary. The intended
use case is for running bisync as a background process (such as via
scheduled <a href="#cron">cron</a>).</p>
<p>When using <code>--resilient</code> mode, bisync will still report
the error and abort, however it will not lock out future runs --
allowing the possibility of retrying at the next normally scheduled
time, without requiring a <code>--resync</code> first. Examples of such
retryable errors include access test failures, missing listing files,
and filter change detections. These safety features will still prevent
the <em>current</em> run from proceeding -- the difference is that if
conditions have improved by the time of the <em>next</em> run, that next
run will be allowed to proceed. Certain more serious errors will still
enforce a <code>--resync</code> lockout, even in
<code>--resilient</code> mode, to prevent data loss.</p>
<p>Behavior of <code>--resilient</code> may change in a future version.
(See also: <a href="#recover"><code>--recover</code></a>, <a
href="#max-lock"><code>--max-lock</code></a>, <a
href="#graceful-shutdown">Graceful Shutdown</a>)</p>
<h3 id="recover">--recover</h3>
<p>If <code>--recover</code> is set, in the event of a sudden
interruption or other un-graceful shutdown, bisync will attempt to
automatically recover on the next run, instead of requiring
<code>--resync</code>. Bisync is able to recover robustly by keeping one
"backup" listing at all times, representing the state of both paths
after the last known successful sync. Bisync can then compare the
current state with this snapshot to determine which changes it needs to
retry. Changes that were synced after this snapshot (during the run that
was later interrupted) will appear to bisync as if they are "new or
changed on both sides", but in most cases this is not a problem, as
bisync will simply do its usual "equality check" and learn that no
action needs to be taken on these files, since they are already
identical on both sides.</p>
<p>In the rare event that a file is synced successfully during a run
that later aborts, and then that same file changes AGAIN before the next
run, bisync will think it is a sync conflict, and handle it accordingly.
(From bisync's perspective, the file has changed on both sides since the
last trusted sync, and the files on either side are not currently
identical.) Therefore, <code>--recover</code> carries with it a slightly
increased chance of having conflicts -- though in practice this is
pretty rare, as the conditions required to cause it are quite specific.
This risk can be reduced by using bisync's <a
href="#graceful-shutdown">"Graceful Shutdown"</a> mode (triggered by
sending <code>SIGINT</code> or <code>Ctrl+C</code>), when you have the
choice, instead of forcing a sudden termination.</p>
<p><code>--recover</code> and <code>--resilient</code> are similar, but
distinct -- the main difference is that <code>--resilient</code> is
about <em>retrying</em>, while <code>--recover</code> is about
<em>recovering</em>. Most users will probably want both.
<code>--resilient</code> allows retrying when bisync has chosen to abort
itself due to safety features such as failing
<code>--check-access</code> or detecting a filter change.
<code>--resilient</code> does not cover external interruptions such as a
user shutting down their computer in the middle of a sync -- that is
what <code>--recover</code> is for.</p>
<h3 id="max-lock">--max-lock</h3>
<p>Bisync uses <a href="#lock-file">lock files</a> as a safety feature
to prevent interference from other bisync runs while it is running.
Bisync normally removes these lock files at the end of a run, but if
bisync is abruptly interrupted, these files will be left behind. By
default, they will lock out all future runs, until the user has a chance
to manually check things out and remove the lock. As an alternative,
<code>--max-lock</code> can be used to make them automatically expire
after a certain period of time, so that future runs are not locked out
forever, and auto-recovery is possible. <code>--max-lock</code> can be
any duration <code>2m</code> or greater (or <code>0</code> to disable).
If set, lock files older than this will be considered "expired", and
future runs will be allowed to disregard them and proceed. (Note that
the <code>--max-lock</code> duration must be set by the process that
left the lock file -- not the later one interpreting it.)</p>
<p>If set, bisync will also "renew" these lock files every
<code>--max-lock minus one minute</code> throughout a run, for extra
safety. (For example, with <code>--max-lock 5m</code>, bisync would
renew the lock file (for another 5 minutes) every 4 minutes until the
run has completed.) In other words, it should not be possible for a lock
file to pass its expiration time while the process that created it is
still running -- and you can therefore be reasonably sure that any
<em>expired</em> lock file you may find was left there by an interrupted
run, not one that is still running and just taking awhile.</p>
<p>If <code>--max-lock</code> is <code>0</code> or not set, the default
is that lock files will never expire, and will block future runs (of
these same two bisync paths) indefinitely.</p>
<p>For maximum resilience from disruptions, consider setting a
relatively short duration like <code>--max-lock 2m</code> along with <a
href="#resilient"><code>--resilient</code></a> and <a
href="#recover"><code>--recover</code></a>, and a relatively frequent <a
href="#cron">cron schedule</a>. The result will be a very robust
"set-it-and-forget-it" bisync run that can automatically bounce back
from almost any interruption it might encounter, without requiring the
user to get involved and run a <code>--resync</code>. (See also: <a
href="#graceful-shutdown">Graceful Shutdown</a> mode)</p>
<h3 id="backup-dir1-and---backup-dir2">--backup-dir1 and
--backup-dir2</h3>
<p>As of <code>v1.66</code>, <a
href="https://rclone.org/docs/#backup-dir-string"><code>--backup-dir</code></a>
is supported in bisync. Because <code>--backup-dir</code> must be a
non-overlapping path on the same remote, Bisync has introduced new
<code>--backup-dir1</code> and <code>--backup-dir2</code> flags to
support separate backup-dirs for <code>Path1</code> and
<code>Path2</code> (bisyncing between different remotes with
<code>--backup-dir</code> would not otherwise be possible.)
<code>--backup-dir1</code> and <code>--backup-dir2</code> can use
different remotes from each other, but <code>--backup-dir1</code> must
use the same remote as <code>Path1</code>, and
<code>--backup-dir2</code> must use the same remote as
<code>Path2</code>. Each backup directory must not overlap its
respective bisync Path without being excluded by a filter rule.</p>
<p>The standard <code>--backup-dir</code> will also work, if both paths
use the same remote (but note that deleted files from both paths would
be mixed together in the same dir). If either <code>--backup-dir1</code>
and <code>--backup-dir2</code> are set, they will override
<code>--backup-dir</code>.</p>
<p>Example:</p>
<pre class="console"><code>rclone bisync /Users/someuser/some/local/path/Bisync gdrive:Bisync --backup-dir1 /Users/someuser/some/local/path/BackupDir --backup-dir2 gdrive:BackupDir --suffix -2023-08-26 --suffix-keep-extension --check-access --max-delete 10 --filters-file /Users/someuser/some/local/path/bisync_filters.txt --no-cleanup --ignore-listing-checksum --checkers=16 --drive-pacer-min-sleep=10ms --create-empty-src-dirs --resilient -MvP --drive-skip-gdocs --fix-case</code></pre>
<p>In this example, if the user deletes a file in
<code>/Users/someuser/some/local/path/Bisync</code>, bisync will
propagate the delete to the other side by moving the corresponding file
from <code>gdrive:Bisync</code> to <code>gdrive:BackupDir</code>. If the
user deletes a file from <code>gdrive:Bisync</code>, bisync moves it
from <code>/Users/someuser/some/local/path/Bisync</code> to
<code>/Users/someuser/some/local/path/BackupDir</code>.</p>
<p>In the event of a <a href="#conflict-loser">rename due to a sync
conflict</a>, the rename is not considered a delete, unless a previous
conflict with the same name already exists and would get
overwritten.</p>

<p>As of <code>rclone v1.64</code>, bisync is now better at detecting
<em>false positive</em> sync conflicts, which would previously have
resulted in unnecessary renames and duplicates. Now, when bisync comes
to a file that it wants to rename (because it is new/changed on both
sides), it first checks whether the Path1 and Path2 versions are
currently <em>identical</em> (using the same underlying function as <a
href="commands/rclone_check/"><code>check</code></a>.) If bisync
concludes that the files are identical, it will skip them and move on.
Otherwise, it will create renamed duplicates, as before. This behavior
also <a
href="https://forum.rclone.org/t/bisync-bugs-and-feature-requests/37636#:~:text=Renamed%20directories">improves
the experience of renaming directories</a>, as a <code>--resync</code>
is no longer required, so long as the same change has been made on both
sides.</p>
<h3 id="all-files-changed">All files changed check</h3>
<p>If <em>all</em> prior existing files on either of the filesystems
have changed (e.g. timestamps have changed due to changing the system's
timezone) then bisync will abort without making any changes. Any new
files are not considered for this check. You could use
<code>--force</code> to force the sync (whichever side has the changed
timestamp files wins). Alternately, a <code>--resync</code> may be used
(Path1 versions will be pushed to Path2). Consider the situation
carefully and perhaps use <code>--dry-run</code> before you commit to
the changes.</p>

<p>By default, bisync compares files by modification time and size. If
you or your application should change the content of a file without
changing the modification time and size, then bisync will <em>not</em>
notice the change, and thus will not copy it to the other side. As an
alternative, consider comparing by checksum (if your remotes support
it). See <a href="#compare"><code>--compare</code></a> for details.</p>
<h3 id="error-handling">Error handling</h3>
<p>Certain bisync critical errors, such as file copy/move failing, will
result in a bisync lockout of following runs. The lockout is asserted
because the sync status and history of the Path1 and Path2 filesystems
cannot be trusted, so it is safer to block any further changes until
someone checks things out. The recovery is to do a <code>--resync</code>
again.</p>
<p>It is recommended to use <code>--resync --dry-run --verbose</code>
initially and <em>carefully</em> review what changes will be made before
running the <code>--resync</code> without <code>--dry-run</code>.</p>
<p>Most of these events come up due to an error status from an internal
call. On such a critical error the <code>{...}.path1.lst</code> and
<code>{...}.path2.lst</code> listing files are renamed to extension
<code>.lst-err</code>, which blocks any future bisync runs (since the
normal <code>.lst</code> files are not found). Bisync keeps them under
<code>bisync</code> subdirectory of the rclone cache directory,
typically at <code>${HOME}/.cache/rclone/bisync/</code> on Linux.</p>
<p>Some errors are considered temporary and re-running the bisync is not
blocked. The <em>critical return</em> blocks further bisync runs.</p>
<p>See also: <a href="#resilient"><code>--resilient</code></a>, <a
href="#recover"><code>--recover</code></a>, <a
href="#max-lock"><code>--max-lock</code></a>, <a
href="#graceful-shutdown">Graceful Shutdown</a></p>
<h3 id="lock-file">Lock file</h3>
<p>When bisync is running, a lock file is created in the bisync working
directory, typically at
<code>~/.cache/rclone/bisync/PATH1..PATH2.lck</code> on Linux. If bisync
should crash or hang, the lock file will remain in place and block any
further runs of bisync <em>for the same paths</em>. Delete the lock file
as part of debugging the situation. The lock file effectively blocks
follow-on (e.g., scheduled by <em>cron</em>) runs when the prior
invocation is taking a long time. The lock file contains <em>PID</em> of
the blocking process, which may help in debug. Lock files can be set to
automatically expire after a certain amount of time, using the <a
href="#max-lock"><code>--max-lock</code></a> flag.</p>
<p><strong>Note</strong> that while concurrent bisync runs are allowed,
<em>be very cautious</em> that there is no overlap in the trees being
synched between concurrent runs, lest there be replicated files, deleted
files and general mayhem.</p>
<h3 id="exit-codes">Exit codes</h3>
<p><code>rclone bisync</code> returns the following codes to calling
program:</p>
<ul>
<li><code>0</code> on a successful run,</li>
<li><code>1</code> for a non-critical failing run (a rerun may be
successful),</li>
<li><code>2</code> on syntax or usage error,</li>
<li><code>7</code> for a critically aborted run (requires a
<code>--resync</code> to recover).</li>
</ul>
<p>See also the section about <a
href="https://rclone.org/docs/#exit-code">exit codes</a> in main
docs.</p>
<h3 id="graceful-shutdown">Graceful Shutdown</h3>
<p>Bisync has a "Graceful Shutdown" mode which is activated by sending
<code>SIGINT</code> or pressing <code>Ctrl+C</code> during a run. Once
triggered, bisync will use best efforts to exit cleanly before the timer
runs out. If bisync is in the middle of transferring files, it will
attempt to cleanly empty its queue by finishing what it has started but
not taking more. If it cannot do so within 30 seconds, it will cancel
the in-progress transfers at that point and then give itself a maximum
of 60 seconds to wrap up, save its state for next time, and exit. With
the <code>-vP</code> flags you will see constant status updates and a
final confirmation of whether or not the graceful shutdown was
successful.</p>
<p>At any point during the "Graceful Shutdown" sequence, a second
<code>SIGINT</code> or <code>Ctrl+C</code> will trigger an immediate,
un-graceful exit, which will leave things in a messier state. Usually a
robust recovery will still be possible if using <a
href="#recover"><code>--recover</code></a> mode, otherwise you will need
to do a <code>--resync</code>.</p>
<p>If you plan to use Graceful Shutdown mode, it is recommended to use
<a href="#resilient"><code>--resilient</code></a> and <a
href="#recover"><code>--recover</code></a>, and it is important to NOT
use <a
href="https://rclone.org/docs/#inplace"><code>--inplace</code></a>,
otherwise you risk leaving partially-written files on one side, which
may be confused for real files on the next run. Note also that in the
event of an abrupt interruption, a <a href="#lock-file">lock file</a>
will be left behind to block concurrent runs. You will need to delete it
before you can proceed with the next run (or wait for it to expire on
its own, if using <code>--max-lock</code>.)</p>
<h2 id="limitations-4">Limitations</h2>
<h3 id="supported-backends">Supported backends</h3>
<p>Bisync is integration-tested against all rclone backends to verify
compatibility. Most backends (including all backends not listed below)
are deemed fully supported with no known issues. Occasionally, however,
these tests reveal issues with particular backends, usually related to a
provider-specific limitation beyond rclone's control (for example,
disallowed special characters and filename encodings.)</p>

</ul>
<p>The above lists are updated for each stable release of rclone. For
test results updated nightly based on the latest beta, visit rclone's <a
href="https://pub.rclone.org/integration-tests/current/">integration
test status page</a>.</p>
<p>Early beta versions of <code>rclone bisync</code> required both
underlying backends to support modification times, and refused to run
otherwise. This limitation has been lifted as of <code>v1.66</code>, as
bisync now supports comparing checksum and/or size instead of (or in
addition to) modtime. See <a href="#compare"><code>--compare</code></a>
for details.</p>
<h3 id="concurrent-modifications">Concurrent modifications</h3>
<p>When using <strong>Local, FTP or SFTP</strong> remotes with <a
href="https://rclone.org/docs/#inplace"><code>--inplace</code></a>,
rclone does not create <em>temporary</em> files at the destination when
copying, and thus if the connection is lost the created file may be
corrupt, which will likely propagate back to the original path on the
next sync, resulting in data loss. It is therefore recommended to
<em>omit</em> <code>--inplace</code>.</p>
<p>Files that <strong>change during</strong> a bisync run may result in
data loss. Prior to <code>rclone v1.66</code>, this was commonly seen in
highly dynamic environments, where the filesystem was getting hammered
by running processes during the sync. As of <code>rclone v1.66</code>,
bisync was redesigned to use a "snapshot" model, greatly reducing the
risks from changes during a sync. Changes that are not detected during
the current sync will now be detected during the following sync, and
will no longer cause the entire run to throw a critical error. There is
additionally a mechanism to mark files as needing to be internally
rechecked next time, for added safety. It should therefore no longer be
necessary to sync only at quiet times -- however, note that an error can
still occur if a file happens to change at the exact moment it's being
read/written by bisync (same as would happen in
<code>rclone sync</code>.) (See also: <a
href="https://rclone.org/docs/#ignore-checksum"><code>--ignore-checksum</code></a>,
<a
href="https://rclone.org/local/#local-no-check-updated"><code>--local-no-check-updated</code></a>)</p>
<h3 id="empty-directories">Empty directories</h3>
<p>By default, new/deleted empty directories on one path are
<em>not</em> propagated to the other side. This is because bisync (and
rclone) natively works on files, not directories. However, this can be
changed with the <code>--create-empty-src-dirs</code> flag, which works
in much the same way as in <a
href="https://rclone.org/commands/rclone_sync/"><code>sync</code></a>
and <a
href="https://rclone.org/commands/rclone_copy/"><code>copy</code></a>.
When used, empty directories created or deleted on one side will also be
created or deleted on the other side. The following should be noted:</p>
<ul>
<li><code>--create-empty-src-dirs</code> is not compatible with
<code>--remove-empty-dirs</code>. Use only one or the other (or
neither).</li>
<li>It is not recommended to switch back and forth between
<code>--create-empty-src-dirs</code> and the default (no
<code>--create-empty-src-dirs</code>) without running
<code>-- resync</code>. This is because it may appear as though all
directories (not just the empty ones) were created/deleted, when
actually you've just toggled between making them visible/invisible to
bisync. It looks scarier than it is, but it's still probably best to
stick to one or the other, and use <code>--resync</code> when you need
to switch.</li>
</ul>
<h3 id="renamed-directories">Renamed directories</h3>
<p>By default, renaming a folder on the Path1 side results in deleting
all files on the Path2 side and then copying all files again from Path1
to Path2. Bisync sees this as all files in the old directory name as
deleted and all files in the new directory name as new.</p>
<p>A recommended solution is to use <a
href="https://rclone.org/docs/#track-renames"><code>--track-renames</code></a>,
which is now supported in bisync as of <code>rclone v1.66</code>. Note
that <code>--track-renames</code> is not available during
<code>--resync</code>, as <code>--resync</code> does not delete anything
(<code>--track-renames</code> only supports <code>sync</code>, not
<code>copy</code>.)</p>
<p>Otherwise, the most effective and efficient method of renaming a
directory is to rename it to the same name on both sides. (As of
<code>rclone v1.64</code>, a <code>--resync</code> is no longer required
after doing so, as bisync will automatically detect that Path1 and Path2
are in agreement.)</p>
<h3 id="fast-list-used-by-default"><code>--fast-list</code> used by
default</h3>
<p>Unlike most other rclone commands, bisync uses <a
href="https://rclone.org/docs/#fast-list"><code>--fast-list</code></a>
by default, for backends that support it. In many cases this is
desirable, however, there are some scenarios in which bisync could be
faster <em>without</em> <code>--fast-list</code>, and there is also a <a
href="https://github.com/rclone/rclone/commit/cbf3d4356135814921382dd3285d859d15d0aa77">known
issue concerning Google Drive users with many empty directories</a>. For
now, the recommended way to avoid using <code>--fast-list</code> is to
add <code>--disable ListR</code> to all bisync commands. The default
behavior may change in a future version.</p>
<h3 id="case-sensitivity">Case (and unicode) sensitivity</h3>
<p>As of <code>v1.66</code>, case and unicode form differences no longer
cause critical errors, and normalization (when comparing between
filesystems) is handled according to the same flags and defaults as
<code>rclone sync</code>. See the following options (all of which are
supported by bisync) to control this behavior more granularly:</p>
<ul>
<li><a
href="https://rclone.org/docs/#fix-case"><code>--fix-case</code></a></li>
<li><a
href="https://rclone.org/docs/#ignore-case-sync"><code>--ignore-case-sync</code></a></li>
<li><a
href="https://rclone.org/docs/#no-unicode-normalization"><code>--no-unicode-normalization</code></a></li>
<li><a
href="https://rclone.org/local/#local-unicode-normalization"><code>--local-unicode-normalization</code></a>
and <a
href="https://rclone.org/local/#local-case-sensitive"><code>--local-case-sensitive</code></a>
(caution: these are normally not what you want.)</li>
</ul>
<p>Note that in the (probably rare) event that <code>--fix-case</code>
is used AND a file is new/changed on both sides AND the checksums match
AND the filename case does not match, the Path1 filename is considered
the winner, for the purposes of <code>--fix-case</code> (Path2 will be
renamed to match it).</p>
<h2 id="windows">Windows support</h2>
<p>Bisync has been tested on Windows 8.1, Windows 10 Pro 64-bit and on
Windows GitHub runners.</p>
<p>Drive letters are allowed, including drive letters mapped to network
drives (<code>rclone bisync J:\localsync GDrive:</code>). If a drive
letter is omitted, the shell current drive is the default. Drive letters
are a single character follows by <code>:</code>, so cloud names must be
more than one character long.</p>
<p>Absolute paths (with or without a drive letter), and relative paths
(with or without a drive letter) are supported.</p>
<p>Working directory is created at
<code>C:\Users\MyLogin\AppData\Local\rclone\bisync</code>.</p>
<p>Note that bisync output may show a mix of forward <code>/</code> and
back <code>\</code> slashes.</p>
<p>Be careful of case independent directory and file naming on Windows
vs. case dependent Linux</p>
<h2 id="filtering">Filtering</h2>
<p>See <a href="https://rclone.org/filtering/">filtering
documentation</a> for how filter rules are written and interpreted.</p>
<p>Bisync's <a href="#filters-file"><code>--filters-file</code></a> flag
slightly extends the rclone's <a
href="https://rclone.org/filtering/#filter-from-read-filtering-patterns-from-a-file">--filter-from</a>
filtering mechanism. For a given bisync run you may provide <em>only
one</em> <code>--filters-file</code>. The <code>--include*</code>,
<code>--exclude*</code>, and <code>--filter</code> flags are also
supported.</p>
<h3 id="how-to-filter-directories">How to filter directories</h3>
<p>Filtering portions of the directory tree is a critical feature for
syncing.</p>
<p>Examples of directory trees (always beneath the Path1/Path2 root
level) you may want to exclude from your sync:</p>
<ul>
<li>Directory trees containing only software build intermediate
files.</li>
<li>Directory trees containing application temporary files and data such
as the Windows <code>C:\Users\MyLogin\AppData\</code> tree.</li>
<li>Directory trees containing files that are large, less important, or
are getting thrashed continuously by ongoing processes.</li>
</ul>
<p>On the other hand, there may be only select directories that you
actually want to sync, and exclude all others. See the <a
href="#include-filters">Example include-style filters for Windows user
directories</a> below.</p>
<h3 id="filters-file-writing-guidelines">Filters file writing
guidelines</h3>
<ol type="1">
<li>Begin with excluding directory trees:
<ul>
<li>e.g. <code>- /AppData/</code></li>
<li><code>**</code> on the end is not necessary. Once a given directory
level is excluded then everything beneath it won't be looked at by
rclone.</li>
<li>Exclude such directories that are unneeded, are big, dynamically
thrashed, or where there may be access permission issues.</li>
<li>Excluding such dirs first will make rclone operations (much)
faster.</li>
<li>Specific files may also be excluded, as with the Dropbox exclusions
example below.</li>
</ul></li>
<li>Decide if it's easier (or cleaner) to:
<ul>
<li>Include select directories and therefore <em>exclude everything
else</em> -- or --</li>
<li>Exclude select directories and therefore <em>include everything
else</em></li>
</ul></li>
<li>Include select directories:
<ul>
<li>Add lines like: <code>+ /Documents/PersonalFiles/**</code> to select
which directories to include in the sync.</li>
<li><code>**</code> on the end specifies to include the full depth of
the specified tree.</li>
<li>With Include-style filters, files at the Path1/Path2 root are not
included. They may be included with <code>+ /*</code>.</li>
<li>Place RCLONE_TEST files within these included directory trees. They
will only be looked for in these directory trees.</li>
<li>Finish by excluding everything else by adding <code>- **</code> at
the end of the filters file.</li>
<li>Disregard step 4.</li>
</ul></li>
<li>Exclude select directories:
<ul>
<li>Add more lines like in step 1. For example:
<code>-/Desktop/tempfiles/</code>, or <code>- /testdir/</code>. Again, a
<code>**</code> on the end is not necessary.</li>
<li>Do <em>not</em> add a <code>- **</code> in the file. Without this
line, everything will be included that has not been explicitly
excluded.</li>
<li>Disregard step 3.</li>
</ul></li>
</ol>
<p>A few rules for the syntax of a filter file expanding on <a
href="https://rclone.org/filtering/">filtering documentation</a>:</p>
<ul>
<li>Lines may start with spaces and tabs - rclone strips leading
whitespace.</li>
<li>If the first non-whitespace character is a <code>#</code> then the
line is a comment and will be ignored.</li>
<li>Blank lines are ignored.</li>
<li>The first non-whitespace character on a filter line must be a
<code>+</code> or <code>-</code>.</li>
<li>Exactly 1 space is allowed between the <code>+/-</code> and the path
term.</li>
<li>Only forward slashes (<code>/</code>) are used in path terms, even
on Windows.</li>
<li>The rest of the line is taken as the path term. Trailing whitespace
is taken literally, and probably is an error.</li>
</ul>
<h3 id="include-filters">Example include-style filters for Windows user
directories</h3>
<p>This Windows <em>include-style</em> example is based on the sync root
(Path1) set to <code>C:\Users\MyLogin</code>. The strategy is to select
specific directories to be synched with a network drive (Path2).</p>
<ul>
<li><code>- /AppData/</code> excludes an entire tree of Windows stored
stuff that need not be synched. In my case, AppData has &gt;11 GB of
stuff I don't care about, and there are some subdirectories beneath
AppData that are not accessible to my user login, resulting in bisync
critical aborts.</li>
<li>Windows creates cache files starting with both upper and lowercase
<code>NTUSER</code> at <code>C:\Users\MyLogin</code>. These files may be
dynamic, locked, and are generally <em>don't care</em>.</li>
<li>There are just a few directories with <em>my</em> data that I do
want synched, in the form of <code>+ /&lt;path&gt;</code>. By selecting
only the directory trees I want to avoid the dozen plus directories that
various apps make at <code>C:\Users\MyLogin\Documents</code>.</li>
<li>Include files in the root of the sync point,
<code>C:\Users\MyLogin</code>, by adding the <code>+ /*</code>
line.</li>
<li>This is an Include-style filters file, therefore it ends with
<code>- **</code> which excludes everything not explicitly
included.</li>
</ul>
<pre class="text"><code>- /AppData/
- NTUSER*
- ntuser*
+ /Documents/Family/**
+ /Documents/Sketchup/**
+ /Documents/Microcapture_Photo/**
+ /Documents/Microcapture_Video/**
+ /Desktop/**
+ /Pictures/**
+ /*
- **</code></pre>
<p>Note also that Windows implements several "library" links such as
<code>C:\Users\MyLogin\My Documents\My Music</code> pointing to
<code>C:\Users\MyLogin\Music</code>. rclone sees these as links, so you
must add <code>--links</code> to the bisync command line if you which to
follow these links. I find that I get permission errors in trying to
follow the links, so I don't include the rclone <code>--links</code>
flag, but then you get lots of <code>Can't follow symlink…</code> noise
from rclone about not following the links. This noise can be quashed by
adding <code>--quiet</code> to the bisync command line.</p>
<h2 id="exclude-filters">Example exclude-style filters files for use
with Dropbox</h2>
<ul>
<li>Dropbox disallows syncing the listed temporary and
configuration/data files. The <code>- &lt;filename&gt;</code> filters
exclude these files where ever they may occur in the sync tree. Consider
adding similar exclusions for file types you don't need to sync, such as
core dump and software build files.</li>
<li>bisync testing creates <code>/testdir/</code> at the top level of
the sync tree, and usually deletes the tree after the test. If a normal
sync should run while the <code>/testdir/</code> tree exists the
<code>--check-access</code> phase may fail due to unbalanced RCLONE_TEST
files. The <code>- /testdir/</code> filter blocks this tree from being
synched. You don't need this exclusion if you are not doing bisync
development testing.</li>
<li>Everything else beneath the Path1/Path2 root will be synched.</li>
<li>RCLONE_TEST files may be placed anywhere within the tree, including
the root.</li>
</ul>

<p>The <code>--dry-run</code> messages may indicate that it would try to
delete some files. For example, if a file is new on Path2 and does not
exist on Path1 then it would normally be copied to Path1, but with
<code>--dry-run</code> enabled those copies don't happen, which leads to
the attempted delete on Path2, blocked again by --dry-run:
<code>... Not deleting as --dry-run</code>.</p>
<p>This whole confusing situation is an artifact of the
<code>--dry-run</code> flag. Scrutinize the proposed deletes carefully,
and if the files would have been copied to Path1 then the threatened

you'll see error and retry messages such as shown below. This is usually
not a bug. If at the end of the run, you see
<code>Bisync successful</code> and not
<code>Bisync critical error</code> or <code>Bisync aborted</code> then
the run was successful, and you can ignore the error messages.</p>
<p>The following run shows an intermittent fail. Lines <em>5</em> and
<em>6</em> are low-level messages. Line <em>6</em> is a bubbled-up
<em>warning</em> message, conveying the error. Rclone normally retries
failing commands, so there may be numerous such messages in the log.</p>
<p>Since there are no final error/warning messages on line <em>7</em>,
rclone has recovered from failure after a retry, and the overall sync
was successful.</p>

<h3 id="denied-downloads-of-infected-or-abusive-files">Denied downloads
of "infected" or "abusive" files</h3>
<p>Google Drive has a filter for certain file types (<code>.exe</code>,
<code>.apk</code>, et cetera) that by default cannot be copied from
Google Drive to the local filesystem. If you are having problems, run
with <code>--verbose</code> to see specifically which files are
generating complaints. If the error is
<code>This file has been identified as malware or spam and cannot be downloaded</code>,
consider using the flag <a
href="https://rclone.org/drive/#drive-acknowledge-abuse">--drive-acknowledge-abuse</a>.</p>
<h3 id="gdocs">Google Docs (and other files of unknown size)</h3>
<p>As of <code>v1.66</code>, <a
href="https://rclone.org/drive/#import-export-of-google-documents">Google
Docs</a> (including Google Sheets, Slides, etc.) are now supported in
bisync, subject to the same options, defaults, and limitations as in
<code>rclone sync</code>. When bisyncing drive with non-drive backends,
the drive -&gt; non-drive direction is controlled by <a
href="https://rclone.org/drive/#drive-export-formats"><code>--drive-export-formats</code></a>
(default <code>"docx,xlsx,pptx,svg"</code>) and the non-drive -&gt;
drive direction is controlled by <a
href="https://rclone.org/drive/#drive-import-formats"><code>--drive-import-formats</code></a>
(default none.)</p>
<p>For example, with the default export/import formats, a Google Sheet
on the drive side will be synced to an <code>.xlsx</code> file on the
non-drive side. In the reverse direction, <code>.xlsx</code> files with
filenames that match an existing Google Sheet will be synced to that
Google Sheet, while <code>.xlsx</code> files that do NOT match an
existing Google Sheet will be copied to drive as normal
<code>.xlsx</code> files (without conversion to Sheets, although the
Google Drive web browser UI may still give you the option to open it as
one.)</p>
<p>If <code>--drive-import-formats</code> is set (it's not, by default),
then all of the specified formats will be converted to Google Docs, if
there is no existing Google Doc with a matching name. Caution: such
conversion can be quite lossy, and in most cases it's probably not what
you want!</p>
<p>To bisync Google Docs as URL shortcut links (in a manner similar to
"Drive for Desktop"), use: <code>--drive-export-formats url</code> (or
<a
href="https://rclone.org/drive/#exportformats:~:text=available%20Google%20Documents.-,Extension,macOS,-Standard%20options">alternatives</a>.)</p>
<p>Note that these link files cannot be edited on the non-drive side --
you will get errors if you try to sync an edited link file back to
drive. They CAN be deleted (it will result in deleting the corresponding
Google Doc.) If you create a <code>.url</code> file on the non-drive
side that does not match an existing Google Doc, bisyncing it will just
result in copying the literal <code>.url</code> file over to drive (no
Google Doc will be created.) So, as a general rule of thumb, think of
them as read-only placeholders on the non-drive side, and make all your
changes on the drive side.</p>
<p>Likewise, even with other export-formats, it is best to only
move/rename Google Docs on the drive side. This is because otherwise,
bisync will interpret this as a file deleted and another created, and
accordingly, it will delete the Google Doc and create a new file at the
new path. (Whether or not that new file is a Google Doc depends on
<code>--drive-import-formats</code>.)</p>
<p>Lastly, take note that all Google Docs on the drive side have a size
of <code>-1</code> and no checksum. Therefore, they cannot be reliably
synced with the <code>--checksum</code> or <code>--size-only</code>
flags. (To be exact: they will still get created/deleted, and bisync's
delta engine will notice changes and queue them for syncing, but the
underlying sync function will consider them identical and skip them.) To
work around this, use the default (modtime and size) instead of
<code>--checksum</code> or <code>--size-only</code>.</p>
<p>To ignore Google Docs entirely, use <a
href="https://rclone.org/drive/#drive-skip-gdocs"><code>--drive-skip-gdocs</code></a>.</p>
<h2 id="usage-examples">Usage examples</h2>
<h3 id="cron">Cron</h3>
<p>Rclone does not yet have a built-in capability to monitor the local
file system for changes and must be blindly run periodically. On Windows
this can be done using a <em>Task Scheduler</em>, on Linux you can use
<em>Cron</em> which is described below.</p>
<p>The 1st example runs a sync every 5 minutes between a local directory
and an OwnCloud server, with output logged to a runlog file:</p>
<pre class="text"><code># Minute (0-59)
#      Hour (0-23)
#           Day of Month (1-31)

#                     Day of Week (0-6 or Sun-Sat)

<p>See <a
href="https://www.man7.org/linux/man-pages/man1/crontab.1p.html#INPUT_FILES">crontab
syntax</a> for the details of crontab time interval expressions.</p>
<p>If you run <code>rclone bisync</code> as a cron job, redirect
stdout/stderr to a file. The 2nd example runs a sync to Dropbox every
hour and logs all stdout (via the <code>&gt;&gt;</code>) and stderr (via
<code>2&gt;&amp;1</code>) to a log file.</p>

<h3 id="sharing-an-encrypted-folder-tree-between-hosts">Sharing an

<p>bisync can keep a local folder in sync with a cloud service, but what
if you have some highly sensitive files to be synched?</p>
<p>Usage of a cloud service is for exchanging both routine and sensitive
personal files between one's home network, one's personal notebook when
on the road, and with one's work computer. The routine data is not
sensitive. For the sensitive data, configure an rclone <a
href="https://rclone.org/crypt/">crypt remote</a> to point to a
subdirectory within the local disk tree that is bisync'd to Dropbox, and
then set up an bisync for this local crypt directory to a directory
outside of the main sync tree.</p>
<h3 id="linux-server-setup">Linux server setup</h3>
<ul>
<li><code>/path/to/DBoxroot</code> is the root of my local sync tree.
There are numerous subdirectories.</li>
<li><code>/path/to/DBoxroot/crypt</code> is the root subdirectory for
files that are encrypted. This local directory target is setup as an
rclone crypt remote named <code>Dropcrypt:</code>. See <a
href="#rclone-conf-snippet">rclone.conf</a> snippet below.</li>
<li><code>/path/to/my/unencrypted/files</code> is the root of my
sensitive files - not encrypted, not within the tree synched to
Dropbox.</li>
<li>To sync my local unencrypted files with the encrypted Dropbox
versions I manually run
<code>bisync /path/to/my/unencrypted/files DropCrypt:</code>. This step
could be bundled into a script to run before and after the full Dropbox
tree sync in the last step, thus actively keeping the sensitive files in
sync.</li>
<li><code>bisync /path/to/DBoxroot Dropbox:</code> runs periodically via
cron, keeping my full local sync tree in sync with Dropbox.</li>
</ul>
<h3 id="windows-notebook-setup">Windows notebook setup</h3>
<ul>
<li>The Dropbox client runs keeping the local tree
<code>C:\Users\MyLogin\Dropbox</code> always in sync with Dropbox. I
could have used <code>rclone bisync</code> instead.</li>
<li>A separate directory tree at
<code>C:\Users\MyLogin\Documents\DropLocal</code> hosts the tree of
unencrypted files/folders.</li>
<li>To sync my local unencrypted files with the encrypted Dropbox
versions I manually run the following command:
<code>rclone bisync C:\Users\MyLogin\Documents\DropLocal Dropcrypt:</code>.</li>
<li>The Dropbox client then syncs the changes with Dropbox.</li>

<h2 id="testing">Testing</h2>
<p>You should read this section only if you are developing for rclone.
You need to have rclone source code locally to work with bisync
tests.</p>
<p>Bisync has a dedicated test framework implemented in the
<code>bisync_test.go</code> file located in the rclone source tree. The
test suite is based on the <code>go test</code> command. Series of tests
are stored in subdirectories below the <code>cmd/bisync/testdata</code>
directory. Individual tests can be invoked by their directory name, e.g.
<code>go test . -case basic -remote local -remote2 gdrive: -v</code></p>
<p>Tests will make a temporary folder on remote and purge it afterwards.
If during test run there are intermittent errors and rclone retries,
these errors will be captured and flagged as invalid MISCOMPAREs.
Rerunning the test will let it pass. Consider such failures as
noise.</p>
<h3 id="test-command-syntax">Test command syntax</h3>
<pre class="text"><code>usage: go test ./cmd/bisync [options...]

Options:
  -case NAME        Name(s) of the test case(s) to run. Multiple names should
                    be separated by commas. You can remove the `test_` prefix
                    and replace `_` by `-` in test name for convenience.
                    If not `all`, the name(s) should map to a directory under
                    `./cmd/bisync/testdata`.
                    Use `all` to run all tests (default: all)
  -remote PATH1     `local` or name of cloud service with `:` (default: local)
  -remote2 PATH2    `local` or name of cloud service with `:` (default: local)
  -no-compare       Disable comparing test results with the golden directory
                    (default: compare)
  -no-cleanup       Disable cleanup of Path1 and Path2 testdirs.
                    Useful for troubleshooting. (default: cleanup)
  -golden           Store results in the golden directory (default: false)
                    This flag can be used with multiple tests.
  -debug            Print debug messages
  -stop-at NUM      Stop test after given step number. (default: run to the end)
                    Implies `-no-compare` and `-no-cleanup`, if the test really
                    ends prematurely. Only meaningful for a single test case.
  -refresh-times    Force refreshing the target modtime, useful for Dropbox
                    (default: false)
  -verbose          Run tests verbosely</code></pre>
<p>Note: unlike rclone flags which must be prefixed by double dash
(<code>--</code>), the test command flags can be equally prefixed by a
single <code>-</code> or double dash.</p>
<h3 id="running-tests">Running tests</h3>
<ul>
<li><code>go test . -case basic -remote local -remote2 local</code> runs
the <code>test_basic</code> test case using only the local filesystem,
syncing one local directory with another local directory. Test script
output is to the console, while commands within scenario.txt have their
output sent to the <code>.../workdir/test.log</code> file, which is
finally compared to the golden copy.</li>
<li>The first argument after <code>go test</code> should be a relative
name of the directory containing bisync source code. If you run tests
right from there, the argument will be <code>.</code> (current
directory) as in most examples below. If you run bisync tests from the
rclone source directory, the command should be
<code>go test ./cmd/bisync ...</code>.</li>
<li>The test engine will mangle rclone output to ensure comparability
with golden listings and logs.</li>
<li>Test scenarios are located in <code>./cmd/bisync/testdata</code>.
The test <code>-case</code> argument should match the full name of a
subdirectory under that directory. Every test subdirectory name on disk
must start with <code>test_</code>, this prefix can be omitted on
command line for brevity. Also, underscores in the name can be replaced
by dashes for convenience.</li>
<li><code>go test . -remote local -remote2 local -case all</code> runs
all tests.</li>
<li>Path1 and Path2 may either be the keyword <code>local</code> or may
be names of configured cloud services.
<code>go test . -remote gdrive: -remote2 dropbox: -case basic</code>
will run the test between these two services, without transferring any
files to the local filesystem.</li>
<li>Test run stdout and stderr console output may be directed to a file,
e.g.
<code>go test . -remote gdrive: -remote2 local -case all &gt; runlog.txt 2&gt;&amp;1</code></li>
</ul>
<h3 id="test-execution-flow">Test execution flow</h3>
<ol type="1">
<li>The base setup in the <code>initial</code> directory of the testcase
is applied on the Path1 and Path2 filesystems (via rclone copy the
initial directory to Path1, then rclone sync Path1 to Path2).</li>
<li>The commands in the scenario.txt file are applied, with output
directed to the <code>test.log</code> file in the test working
directory. Typically, the first actual command in the
<code>scenario.txt</code> file is to do a <code>--resync</code>, which
establishes the baseline <code>{...}.path1.lst</code> and
<code>{...}.path2.lst</code> files in the test working directory
(<code>.../workdir/</code> relative to the temporary test directory).
Various commands and listing snapshots are done within the test.</li>
<li>Finally, the contents of the test working directory are compared to
the contents of the testcase's golden directory.</li>
</ol>
<h3 id="notes-about-testing">Notes about testing</h3>
<ul>
<li>Test cases are in individual directories beneath
<code>./cmd/bisync/testdata</code>. A command line reference to a test
is understood to reference a directory beneath <code>testdata</code>.
For example,
<code>go test ./cmd/bisync -case dry-run -remote gdrive: -remote2 local</code>
refers to the test case in
<code>./cmd/bisync/testdata/test_dry_run</code>.</li>
<li>The test working directory is located at <code>.../workdir</code>
relative to a temporary test directory, usually under <code>/tmp</code>
on Linux.</li>
<li>The local test sync tree is created at a temporary directory named
like <code>bisync.XXX</code> under system temporary directory.</li>
<li>The remote test sync tree is located at a temporary directory under
<code>&lt;remote:&gt;/bisync.XXX/</code>.</li>
<li><code>path1</code> and/or <code>path2</code> subdirectories are
created in a temporary directory under the respective local or cloud
test remote.</li>
<li>By default, the Path1 and Path2 test dirs and workdir will be
deleted after each test run. The <code>-no-cleanup</code> flag disables
purging these directories when validating and debugging a given test.
These directories will be flushed before running another test,
independent of the <code>-no-cleanup</code> usage.</li>
<li>You will likely want to add <code>- /testdir/</code> to your normal
bisync <code>--filters-file</code> so that normal syncs do not attempt
to sync the test temporary directories, which may have
<code>RCLONE_TEST</code> miscompares in some testcases which would
otherwise trip the <code>--check-access</code> system. The
<code>--check-access</code> mechanism is hard-coded to ignore
<code>RCLONE_TEST</code> files beneath <code>bisync/testdata</code>, so
the test cases may reside on the synched tree even if there are check
file mismatches in the test tree.</li>
<li>Some Dropbox tests can fail, notably printing the following message:
<code>src and dst identical but can't set mod time without deleting and re-uploading</code>
This is expected and happens due to the way Dropbox handles modification
times. You should use the <code>-refresh-times</code> test flag to make
up for this.</li>
<li>If Dropbox tests hit request limit for you and print error message
<code>too_many_requests/...: Too many requests or write operations.</code>
then follow the <a
href="https://rclone.org/dropbox/#get-your-own-dropbox-app-id">Dropbox
App ID instructions</a>.</li>
</ul>
<h3 id="updating-golden-results">Updating golden results</h3>
<p>Sometimes even a slight change in the bisync source can cause little
changes spread around many log files. Updating them manually would be a
nightmare.</p>
<p>The <code>-golden</code> flag will store the <code>test.log</code>
and <code>*.lst</code> listings from each test case into respective
golden directories. Golden results will automatically contain generic
strings instead of local or cloud paths which means that they should
match when run with a different cloud service.</p>
<p>Your normal workflow might be as follows:</p>
<ol type="1">
<li>Git-clone the rclone sources locally</li>
<li>Modify bisync source and check that it builds</li>
<li>Run the whole test suite
<code>go test ./cmd/bisync -remote local</code></li>
<li>If some tests show log difference, recheck them individually, e.g.:
<code>go test ./cmd/bisync -remote local -case basic</code></li>
<li>If you are convinced with the difference, goldenize all tests at
once: <code>go test ./cmd/bisync -remote local -golden</code></li>
<li>Use word diff:
<code>git diff --word-diff ./cmd/bisync/testdata/</code>. Please note
that normal line-level diff is generally useless here.</li>
<li>Check the difference <em>carefully</em>!</li>
<li>Commit the change (<code>git commit</code>) <em>only</em> if you are
sure. If unsure, save your code changes then wipe the log diffs from
git: <code>git reset [--hard]</code>.</li>
</ol>
<h3 id="structure-of-test-scenarios">Structure of test scenarios</h3>
<ul>
<li><code>&lt;testname&gt;/initial/</code> contains a tree of files that
will be set as the initial condition on both Path1 and Path2
testdirs.</li>
<li><code>&lt;testname&gt;/modfiles/</code> contains files that will be
used to modify the Path1 and/or Path2 filesystems.</li>
<li><code>&lt;testname&gt;/golden/</code> contains the expected content
of the test working directory (<code>workdir</code>) at the completion
of the testcase.</li>
<li><code>&lt;testname&gt;/scenario.txt</code> contains the body of the
test, in the form of various commands to modify files, run bisync, and
snapshot listings. Output from these commands is captured to
<code>.../workdir/test.log</code> for comparison to the golden
files.</li>
</ul>
<h3 id="supported-test-commands">Supported test commands</h3>
<ul>
<li><code>test &lt;some message&gt;</code> Print the line to the console
and to the <code>test.log</code>:
<code>test sync is working correctly with options x, y, z</code></li>

<li><code>move-listings &lt;prefix&gt;</code> Similar to
<code>copy-listings</code> but removes the source</li>
<li><code>purge-children &lt;dir&gt;</code> This will delete all child
files and purge all child subdirs under given directory but keep the
parent intact. This behavior is important for tests with Google Drive
because removing and re-creating the parent would change its ID.</li>
<li><code>delete-file &lt;file&gt;</code> Delete a single file.</li>

<p><em>This section is work in progress.</em></p>
<p>Here are a few data points for scale, execution times, and memory

<p>This next data is from a user's application. They had ~400GB of data
over 1.96 million files being sync'ed between a Windows local disk and
some remote cloud. The file full path length was on average 35
characters (which factors into load time and RAM required).</p>
<ul>
<li>Loading the prior listing into memory (1.96 million files, listing
file size 140 MB) took ~30 sec and occupied about 1 GB of RAM.</li>
<li>Getting a fresh listing of the local file system (producing the 140
MB output file) took about XXX sec.</li>
<li>Getting a fresh listing of the remote file system (producing the 140
MB output file) took about XXX sec. The network download speed was
measured at XXX Mb/s.</li>
<li>Once the prior and current Path1 and Path2 listings were loaded (a
total of four to be loaded, two at a time), determining the deltas was
pretty quick (a few seconds for this test case), and the transfer time
for any files to be copied was dominated by the network bandwidth.</li>

<p>Bisync adopts the differential synchronization technique, which is
based on keeping history of changes performed by both synchronizing
sides. See the <em>Dual Shadow Method</em> section in <a
href="https://neil.fraser.name/writing/sync/">Neil Fraser's
article</a>.</p>

<h1 id="release-signing">Release signing</h1>
<p>The hashes of the binary artefacts of the rclone release are signed
with a public PGP/GPG key. This can be verified manually as described
below.</p>
<p>The same mechanism is also used by <a
href="https://rclone.org/commands/rclone_selfupdate/">rclone
selfupdate</a> to verify that the release has not been tampered with
before the new update is installed. This checks the SHA256 hash and the
signature with a public key compiled into the rclone binary.</p>
<h2 id="release-signing-key">Release signing key</h2>
<p>You may obtain the release signing key from:</p>
<ul>
<li>From <a href="/KEYS">KEYS</a> on this website - this file contains
all past signing keys also.</li>
<li>The git repository hosted on GitHub - <a

</ul>
<p>After importing the key, verify that the fingerprint of one of the
keys matches: <code>FBF737ECE9F8AB18604BD2AC93935E02FF3B54FA</code> ads
this key is used for signing.</p>
<p>We recommend that you cross-check the fingerprint shown above through
the domains listed below. By cross-checking the integrity of the
fingerprint across multiple domains you can be confident that you
obtained the correct key.</p>

<h2 id="how-to-verify-the-release">How to verify the release</h2>
<p>In the release directory you will see the release files and some
files called <code>MD5SUMS</code>, <code>SHA1SUMS</code> and

<h3 id="download-the-files">Download the files</h3>
<p>The first step is to download the binary and SUMs file and verify
that the SUMs you have downloaded match. Here we download
<code>rclone-v1.63.1-windows-amd64.zip</code> - choose the binary (or
binaries) appropriate to your architecture. We've also chosen the
<code>SHA256SUMS</code> as these are the most secure. You could verify
the other types of hash also for extra security.
<code>rclone selfupdate</code> verifies just the
<code>SHA256SUMS</code>.</p>
<pre class="console"><code>mkdir /tmp/check

<h3 id="verify-the-signatures">Verify the signatures</h3>
<p>First verify the signatures on the SHA256 file.</p>
<p>Import the key. See above for ways to verify this key is correct.</p>
<pre class="console"><code>$ gpg --keyserver keyserver.ubuntu.com --receive-keys FBF737ECE9F8AB18604BD2AC93935E02FF3B54FA

<h2 id="limitations-5">Limitations</h2>
<p><code>rclone about</code> is not supported by the 1Fichier backend.
Backends without this capability cannot determine free space for an
rclone mount or use policy <code>mfs</code> (most free space) as a
member of an rclone union remote.</p>
<p>See <a href="https://rclone.org/overview/#optional-features">List of
backends that do not support rclone about</a> and <a
href="https://rclone.org/commands/rclone_about/">rclone about</a>.</p>
<h1 id="alias">Alias</h1>
<p>The <code>alias</code> remote provides a new name for another
remote.</p>
<p>Paths may be as deep as required or a local path, e.g.
<code>remote:directory/subdirectory</code> or
<code>/directory/subdirectory</code>.</p>
<p>During the initial setup with <code>rclone config</code> you will
specify the target remote. The target remote can either be a local path
or another remote.</p>
<p>Subfolders can be used in target remote. Assume an alias remote named
<code>backup</code> with the target <code>mydrive:private/backup</code>.
Invoking <code>rclone mkdir backup:desktop</code> is exactly the same as
invoking <code>rclone mkdir mydrive:private/backup/desktop</code>.</p>
<p>There will be no special handling of paths containing <code>..</code>
segments. Invoking <code>rclone mkdir backup:../desktop</code> is
exactly the same as invoking
<code>rclone mkdir mydrive:private/backup/../desktop</code>. The empty
path is not allowed as a remote. To alias the current directory use
<code>.</code> instead.</p>
<p>The target remote can also be a <a
href="https://rclone.org/docs/#connection-strings">connection
string</a>. This can be used to modify the config of a remote for
different uses, e.g. the alias <code>myDriveTrash</code> with the target
remote <code>myDrive,trashed_only:</code> can be used to only show the
trashed files in <code>myDrive</code>.</p>
<h2 id="configuration-1">Configuration</h2>
<p>Here is an example of how to make an alias called <code>remote</code>
for local folder. First run:</p>
<pre class="console"><code>rclone config</code></pre>

<h3 id="modification-times-and-hashes-1">Modification times and
hashes</h3>
<h4 id="modification-times-1">Modification times</h4>
<p>The modified time is stored as metadata on the object as
<code>X-Amz-Meta-Mtime</code> as floating point since the epoch,
accurate to 1 ns.</p>
<p>If the modification time needs to be updated rclone will attempt to
perform a server side copy to update the modification if the object can
be copied in a single part. In the case the object is larger than 5Gb or
is in Glacier or Glacier Deep Archive storage the object will be
uploaded rather than copied.</p>
<p>Note that reading this from the object takes an additional
<code>HEAD</code> request as the metadata isn't returned in object
listings.</p>
<h4 id="hashes">Hashes</h4>
<p>For small objects which weren't uploaded as multipart uploads
(objects sized below <code>--s3-upload-cutoff</code> if uploaded with
rclone) rclone uses the <code>ETag:</code> header as an MD5
checksum.</p>
<p>However for objects which were uploaded as multipart uploads or with
server side encryption (SSE-AWS or SSE-C) the <code>ETag</code> header
is no longer the MD5 sum of the data, so rclone adds an additional piece
of metadata <code>X-Amz-Meta-Md5chksum</code> which is a base64 encoded
MD5 hash (in the same format as is required for
<code>Content-MD5</code>). You can use base64 -d and hexdump to check
this value manually:</p>
<pre class="console"><code>echo &#39;VWTGdNx3LyXQDfA0e2Edxw==&#39; | base64 -d | hexdump</code></pre>
<p>or you can use <code>rclone check</code> to verify the hashes are
OK.</p>
<p>For large objects, calculating this hash can take some time so the
addition of this hash can be disabled with
<code>--s3-disable-checksum</code>. This will mean that these objects do
not have an MD5 checksum.</p>
<p>Note that reading this from the object takes an additional
<code>HEAD</code> request as the metadata isn't returned in object
listings.</p>
<h3 id="reducing-costs">Reducing costs</h3>
<h4 id="avoiding-head-requests-to-read-the-modification-time">Avoiding
HEAD requests to read the modification time</h4>
<p>By default, rclone will use the modification time of objects stored
in S3 for syncing. This is stored in object metadata which unfortunately
takes an extra HEAD request to read which can be expensive (in time and
money).</p>
<p>The modification time is used by default for all operations that
require checking the time a file was last updated. It allows rclone to
treat the remote more like a true filesystem, but it is inefficient on
S3 because it requires an extra API call to retrieve the metadata.</p>
<p>The extra API calls can be avoided when syncing (using
<code>rclone sync</code> or <code>rclone copy</code>) in a few different
ways, each with its own tradeoffs.</p>
<ul>
<li><code>--size-only</code>
<ul>
<li>Only checks the size of files.</li>
<li>Uses no extra transactions.</li>
<li>If the file doesn't change size then rclone won't detect it has
changed.</li>
<li><code>rclone sync --size-only /path/to/source s3:bucket</code></li>
</ul></li>
<li><code>--checksum</code>
<ul>
<li>Checks the size and MD5 checksum of files.</li>
<li>Uses no extra transactions.</li>
<li>The most accurate detection of changes possible.</li>
<li>Will cause the source to read an MD5 checksum which, if it is a
local disk, will cause lots of disk activity.</li>
<li>If the source and destination are both S3 this is the
<strong>recommended</strong> flag to use for maximum efficiency.</li>
<li><code>rclone sync --checksum /path/to/source s3:bucket</code></li>
</ul></li>
<li><code>--update --use-server-modtime</code>
<ul>
<li>Uses no extra transactions.</li>
<li>Modification time becomes the time the object was uploaded.</li>
<li>For many operations this is sufficient to determine if it needs
uploading.</li>
<li>Using <code>--update</code> along with
<code>--use-server-modtime</code>, avoids the extra API call and uploads
files whose local modification time is newer than the time it was last
uploaded.</li>
<li>Files created with timestamps in the past will be missed by the
sync.</li>
<li><code>rclone sync --update --use-server-modtime /path/to/source s3:bucket</code></li>
</ul></li>
</ul>
<p>These flags can and should be used in combination with
<code>--fast-list</code> - see below.</p>
<p>If using <code>rclone mount</code> or any command using the VFS (eg
<code>rclone serve</code>) commands then you might want to consider
using the VFS flag <code>--no-modtime</code> which will stop rclone
reading the modification time for every object. You could also use
<code>--use-server-modtime</code> if you are happy with the modification
times of the objects being the time of upload.</p>
<h4 id="avoiding-get-requests-to-read-directory-listings">Avoiding GET
requests to read directory listings</h4>
<p>Rclone's default directory traversal is to process each directory
individually. This takes one API call per directory. Using the
<code>--fast-list</code> flag will read all info about the objects into
memory first using a smaller number of API calls (one per 1000 objects).
See the <a href="https://rclone.org/docs/#fast-list">rclone docs</a> for
more details.</p>
<pre class="console"><code>rclone sync --fast-list --checksum /path/to/source s3:bucket</code></pre>
<p><code>--fast-list</code> trades off API transactions for memory use.
As a rough guide rclone uses 1k of memory per object stored, so using
<code>--fast-list</code> on a sync of a million objects will use roughly
1 GiB of RAM.</p>
<p>If you are only copying a small number of files into a big repository
then using <code>--no-traverse</code> is a good idea. This finds objects
directly instead of through directory listings. You can do a "top-up"
sync very cheaply by using <code>--max-age</code> and
<code>--no-traverse</code> to copy only recent files, eg</p>
<pre class="console"><code>rclone copy --max-age 24h --no-traverse /path/to/source s3:bucket</code></pre>
<p>You'd then do a full <code>rclone sync</code> less often.</p>
<p>Note that <code>--fast-list</code> isn't required in the top-up
sync.</p>
<h4 id="avoiding-head-requests-after-put">Avoiding HEAD requests after
PUT</h4>
<p>By default, rclone will HEAD every object it uploads. It does this to
check the object got uploaded correctly.</p>
<p>You can disable this with the <a href="#s3-no-head">--s3-no-head</a>
option - see there for more details.</p>
<p>Setting this flag increases the chance for undetected upload
failures.</p>
<h3 id="increasing-performance">Increasing performance</h3>
<h4 id="using-server-side-copy">Using server-side copy</h4>
<p>If you are copying objects between S3 buckets in the same region, you
should use server-side copy. This is much faster than downloading and
re-uploading the objects, as no data is transferred.</p>
<p>For rclone to use server-side copy, you must use the same remote for
the source and destination.</p>
<pre class="console"><code>rclone copy s3:source-bucket s3:destination-bucket</code></pre>
<p>When using server-side copy, the performance is limited by the rate
at which rclone issues API requests to S3. See below for how to increase
the number of API requests rclone makes.</p>
<h4 id="increasing-the-rate-of-api-requests">Increasing the rate of API
requests</h4>
<p>You can increase the rate of API requests to S3 by increasing the
parallelism using <code>--transfers</code> and <code>--checkers</code>
options.</p>
<p>Rclone uses a very conservative defaults for these settings, as not
all providers support high rates of requests. Depending on your
provider, you can increase significantly the number of transfers and
checkers.</p>
<p>For example, with AWS S3, if you can increase the number of checkers
to values like 200. If you are doing a server-side copy, you can also
increase the number of transfers to 200.</p>
<pre class="console"><code>rclone sync --transfers 200 --checkers 200 --checksum s3:source-bucket s3:destination-bucket</code></pre>
<p>You will need to experiment with these values to find the optimal
settings for your setup.</p>
<h3 id="data-integrity">Data integrity</h3>
<p>Rclone does its best to verify every part of an upload or download to
the s3 provider using various hashes.</p>
<p>Every HTTP transaction to/from the provider has a
<code>X-Amz-Content-Sha256</code> or a <code>Content-Md5</code> header
to guard against corruption of the HTTP body. The HTTP Header is
protected by the signature passed in the <code>Authorization</code>
header.</p>
<p>All communications with the provider is done over https for
encryption and additional error protection.</p>
<h4 id="single-part-uploads">Single part uploads</h4>
<ul>
<li><p>Rclone uploads single part uploads with a
<code>Content-Md5</code> using the MD5 hash read from the source. The
provider checks this is correct on receipt of the data.</p></li>
<li><p>Rclone then does a HEAD request (disable with
<code>--s3-no-head</code>) to read the <code>ETag</code> back which is
the MD5 of the file and checks that with what it sent.</p></li>
</ul>
<p>Note that if the source does not have an MD5 then the single part
uploads will not have hash protection. In this case it is recommended to
use <code>--s3-upload-cutoff 0</code> so all files are uploaded as
multipart uploads.</p>
<h4 id="multipart-uploads">Multipart uploads</h4>
<p>For files above <code>--s3-upload-cutoff</code> rclone splits the
file into multiple parts for upload.</p>
<ul>
<li>Each part is protected with both an
<code>X-Amz-Content-Sha256</code> and a <code>Content-Md5</code></li>
</ul>
<p>When rclone has finished the upload of all the parts it then
completes the upload by sending:</p>
<ul>
<li>The MD5 hash of each part</li>
<li>The number of parts</li>
<li>This info is all protected with a
<code>X-Amz-Content-Sha256</code></li>
</ul>
<p>The provider checks the MD5 for all the parts it has received against
what rclone sends and if it is good it returns OK.</p>
<p>Rclone then does a HEAD request (disable with
<code>--s3-no-head</code>) and checks the ETag is what it expects (in
this case it should be the MD5 sum of all the MD5 sums of all the parts
with the number of parts on the end).</p>
<p>If the source has an MD5 sum then rclone will attach the
<code>X-Amz-Meta-Md5chksum</code> with it as the <code>ETag</code> for a
multipart upload can't easily be checked against the file as the chunk
size must be known in order to calculate it.</p>
<h4 id="downloads">Downloads</h4>
<p>Rclone checks the MD5 hash of the data downloaded against either the
ETag or the <code>X-Amz-Meta-Md5chksum</code> metadata (if present)
which rclone uploads with multipart uploads.</p>
<h4 id="further-checking">Further checking</h4>
<p>At each stage rclone and the provider are sending and checking hashes
of <strong>everything</strong>. Rclone deliberately HEADs each object
after upload to check it arrived safely for extra security. (You can
disable this with <code>--s3-no-head</code>).</p>
<p>If you require further assurance that your data is intact you can use
<code>rclone check</code> to check the hashes locally vs the remote.</p>
<p>And if you are feeling ultimately paranoid use
<code>rclone check --download</code> which will download the files and
check them against the local copies. (Note that this doesn't use disk to
do this - it streams them in memory).</p>
<h3 id="versions">Versions</h3>
<p>When bucket versioning is enabled (this can be done with rclone with
the <a href="#versioning"><code>rclone backend versioning</code></a>
command) when rclone uploads a new version of a file it creates a <a
href="https://docs.aws.amazon.com/AmazonS3/latest/userguide/Versioning.html">new
version of it</a> Likewise when you delete a file, the old version will
be marked hidden and still be available.</p>
<p>Old versions of files, where available, are visible using the <a
href="#s3-versions"><code>--s3-versions</code></a> flag.</p>
<p>It is also possible to view a bucket as it was at a certain point in
time, using the <a
href="#s3-version-at"><code>--s3-version-at</code></a> flag. This will
show the file versions as they were at that time, showing files that
have been deleted afterwards, and hiding files that were created
since.</p>
<p>If you wish to remove all the old versions then you can use the <a
href="#cleanup-hidden"><code>rclone backend cleanup-hidden remote:bucket</code></a>
command which will delete all the old hidden versions of files, leaving
the current ones intact. You can also supply a path and only old
versions under that path will be deleted, e.g.
<code>rclone backend cleanup-hidden remote:bucket/path/to/stuff</code>.</p>
<p>When you <code>purge</code> a bucket, the current and the old
versions will be deleted then the bucket will be deleted.</p>
<p>However <code>delete</code> will cause the current versions of the
files to become hidden old versions.</p>
<p>Here is a session showing the listing and retrieval of an old version
followed by a <code>cleanup</code> of the old versions.</p>
<p>Show current version and all the versions with
<code>--s3-versions</code> flag.</p>
<pre class="console"><code>$ rclone -q ls s3:cleanup-test
        9 one.txt

$ rclone -q --s3-versions ls s3:cleanup-test
        9 one.txt
        8 one-v2016-07-04-141032-000.txt
       16 one-v2016-07-04-141003-000.txt
       15 one-v2016-07-02-155621-000.txt</code></pre>
<p>Retrieve an old version</p>
<pre class="console"><code>$ rclone -q --s3-versions copy s3:cleanup-test/one-v2016-07-04-141003-000.txt /tmp

$ ls -l /tmp/one-v2016-07-04-141003-000.txt
-rw-rw-r-- 1 ncw ncw 16 Jul  2 17:46 /tmp/one-v2016-07-04-141003-000.txt</code></pre>
<p>Clean up all the old versions and show that they've gone.</p>
<pre class="console"><code>$ rclone -q backend cleanup-hidden s3:cleanup-test

$ rclone -q ls s3:cleanup-test
        9 one.txt

$ rclone -q --s3-versions ls s3:cleanup-test
        9 one.txt</code></pre>
<h4 id="versions-naming-caveat">Versions naming caveat</h4>
<p>When using <code>--s3-versions</code> flag rclone is relying on the
file name to work out whether the objects are versions or not. Versions'
names are created by inserting timestamp between file name and its
extension.</p>
<pre class="text"><code>        9 file.txt
        8 file-v2023-07-17-161032-000.txt
       16 file-v2023-06-15-141003-000.txt</code></pre>
<p>If there are real files present with the same names as versions, then
behaviour of <code>--s3-versions</code> can be unpredictable.</p>
<h3 id="cleanup-1">Cleanup</h3>
<p>If you run <code>rclone cleanup s3:bucket</code> then it will remove
all pending multipart uploads older than 24 hours. You can use the
<code>--interactive</code>/<code>i</code> or <code>--dry-run</code> flag
to see exactly what it will do. If you want more control over the expiry
date then run
<code>rclone backend cleanup s3:bucket -o max-age=1h</code> to expire
all uploads older than one hour. You can use
<code>rclone backend list-multipart-uploads s3:bucket</code> to see the
pending multipart uploads.</p>
<h3 id="restricted-filename-characters-1">Restricted filename
characters</h3>
<p>S3 allows any valid UTF-8 string as a key.</p>
<p>Invalid UTF-8 bytes will be <a
href="https://rclone.org/overview/#invalid-utf8">replaced</a>, as they
can't be used in XML.</p>
<p>The following characters are replaced since these are problematic
when dealing with the REST API:</p>
<table>
<thead>
<tr class="header">

<h3 id="multipart-uploads-1">Multipart uploads</h3>
<p>rclone supports multipart uploads with S3 which means that it can
upload files bigger than 5 GiB.</p>
<p>Note that files uploaded <em>both</em> with multipart upload
<em>and</em> through crypt remotes do not have MD5 sums.</p>
<p>rclone switches from single part uploads to multipart uploads at the
point specified by <code>--s3-upload-cutoff</code>. This can be a
maximum of 5 GiB and a minimum of 0 (ie always upload multipart
files).</p>
<p>The chunk sizes used in the multipart upload are specified by
<code>--s3-chunk-size</code> and the number of chunks uploaded
concurrently is specified by <code>--s3-upload-concurrency</code>.</p>
<p>Multipart uploads will use extra memory equal to:
<code>--transfers</code> × <code>--s3-upload-concurrency</code> ×
<code>--s3-chunk-size</code>. Single part uploads do not use extra
memory.</p>
<p>Single part transfers can be faster than multipart transfers or
slower depending on your latency from S3 - the more latency, the more
likely single part transfers will be faster.</p>
<p>Increasing <code>--s3-upload-concurrency</code> will increase
throughput (8 would be a sensible value) and increasing
<code>--s3-chunk-size</code> also increases throughput (16M would be
sensible). Increasing either of these will use more memory. The default
values are high enough to gain most of the possible performance without
using too much memory.</p>
<h3 id="buckets-and-regions">Buckets and Regions</h3>
<p>With Amazon S3 you can list buckets (<code>rclone lsd</code>) using
any region, but you can only access the content of a bucket from the
region it was created in. If you attempt to access a bucket from the
wrong region, you will get an error,
<code>incorrect region, the bucket is not in 'XXX' region</code>.</p>
<h3 id="authentication-6">Authentication</h3>
<p>There are a number of ways to supply <code>rclone</code> with a set
of AWS credentials, with and without using the environment.</p>
<p>The different authentication methods are tried in this order:</p>
<ul>
<li>Directly in the rclone configuration file
(<code>env_auth = false</code> in the config file):
<ul>
<li><code>access_key_id</code> and <code>secret_access_key</code> are
required.</li>
<li><code>session_token</code> can be optionally set when using AWS
STS.</li>
</ul></li>
<li>Runtime configuration (<code>env_auth = true</code> in the config
file):
<ul>
<li>Export the following environment variables before running
<code>rclone</code>:
<ul>
<li>Access Key ID: <code>AWS_ACCESS_KEY_ID</code> or
<code>AWS_ACCESS_KEY</code></li>
<li>Secret Access Key: <code>AWS_SECRET_ACCESS_KEY</code> or
<code>AWS_SECRET_KEY</code></li>
<li>Session Token: <code>AWS_SESSION_TOKEN</code> (optional)</li>
</ul></li>
<li>Or, use a <a
href="https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-files.html">named
profile</a>:
<ul>
<li>Profile files are standard files used by AWS CLI tools</li>
<li>By default it will use the profile in your home directory (e.g.
<code>~/.aws/credentials</code> on unix based systems) file and the
"default" profile, to change set these environment variables or config
keys:
<ul>
<li><code>AWS_SHARED_CREDENTIALS_FILE</code> to control which file or
the <code>shared_credentials_file</code> config key.</li>
<li><code>AWS_PROFILE</code> to control which profile to use or the
<code>profile</code> config key.</li>
</ul></li>
</ul></li>
<li>Or, run <code>rclone</code> in an ECS task with an IAM role (AWS
only).</li>
<li>Or, run <code>rclone</code> on an EC2 instance with an IAM role (AWS
only).</li>
<li>Or, run <code>rclone</code> in an EKS pod with an IAM role that is
associated with a service account (AWS only).</li>
<li>Or, use <a
href="https://docs.aws.amazon.com/sdkref/latest/guide/feature-process-credentials.html">process
credentials</a> to read config from an external program.</li>
</ul></li>
</ul>
<p>With <code>env_auth = true</code> rclone (which uses the SDK for Go
v2) should support <a
href="https://docs.aws.amazon.com/sdkref/latest/guide/standardized-credentials.html">all
authentication methods</a> that the <code>aws</code> CLI tool does and
the other AWS SDKs.</p>
<p>If none of these option actually end up providing <code>rclone</code>
with AWS credentials then S3 interaction will be non-authenticated (see
the <a href="#anonymous-access">anonymous access</a> section for more
info).</p>
<h3 id="s3-permissions">S3 Permissions</h3>
<p>When using the <code>sync</code> subcommand of <code>rclone</code>
the following minimum permissions are required to be available on the
bucket being written to:</p>
<ul>
<li><code>ListBucket</code></li>
<li><code>DeleteObject</code></li>
<li><code>GetObject</code></li>
<li><code>PutObject</code></li>
<li><code>PutObjectACL</code></li>
<li><code>CreateBucket</code> (unless using <a
href="#s3-no-check-bucket">s3-no-check-bucket</a>)</li>
</ul>
<p>When using the <code>lsd</code> subcommand, the
<code>ListAllMyBuckets</code> permission is required.</p>

<h3 id="key-management-system-kms">Key Management System (KMS)</h3>
<p>If you are using server-side encryption with KMS then you must make

<p>You can upload objects using the glacier storage class or transition
them to glacier using a <a

policy</a>. The bucket can still be synced or copied into normally, but
if rclone tries to access data from the glacier storage class you will
see an error like below.</p>
<pre class="text"><code>2017/09/11 19:07:43 Failed to sync: failed to open source object: Object in GLACIER, restore first: path/to/file</code></pre>
<p>In this case you need to <a

the object(s) in question before accessing object contents. The <a

on S3 Object Lock</a>:</p>
<blockquote>
<p>If you configure a default retention period on a bucket, requests to
upload objects in such a bucket must include the Content-MD5 header.</p>
</blockquote>
<p>As mentioned in the <a

<h4 id="s3-acl">--s3-acl</h4>
<p>Canned ACL used when creating buckets and storing or copying
objects.</p>
<p>This ACL is used for creating objects and if bucket_acl isn't set,
for creating buckets too.</p>
<p>For more info visit
https://docs.aws.amazon.com/AmazonS3/latest/dev/acl-overview.html#canned-acl</p>
<p>Note that this ACL is applied when server-side copying objects as S3
doesn't copy the ACL from the source but rather writes a fresh one.</p>
<p>If the acl is an empty string then no X-Amz-Acl: header is added and
the default (private) will be used.</p>

<h4 id="s3-upload-cutoff">--s3-upload-cutoff</h4>
<p>Cutoff for switching to chunked upload.</p>
<p>Any files larger than this will be uploaded in chunks of chunk_size.
The minimum is 0 and the maximum is 5 GiB.</p>
<p>Properties:</p>
<ul>
<li>Config: upload_cutoff</li>
<li>Env Var: RCLONE_S3_UPLOAD_CUTOFF</li>
<li>Type: SizeSuffix</li>
<li>Default: 200Mi</li>
</ul>
<h4 id="s3-chunk-size">--s3-chunk-size</h4>
<p>Chunk size to use for uploading.</p>
<p>When uploading files larger than upload_cutoff or files with unknown
size (e.g. from "rclone rcat" or uploaded with "rclone mount" or google
photos or google docs) they will be uploaded as multipart uploads using
this chunk size.</p>
<p>Note that "--s3-upload-concurrency" chunks of this size are buffered
in memory per transfer.</p>
<p>If you are transferring large files over high-speed links and you
have enough memory, then increasing this will speed up the
transfers.</p>
<p>Rclone will automatically increase the chunk size when uploading a
large file of known size to stay below the 10,000 chunks limit.</p>
<p>Files of unknown size are uploaded with the configured chunk_size.
Since the default chunk size is 5 MiB and there can be at most 10,000
chunks, this means that by default the maximum size of a file you can
stream upload is 48 GiB. If you wish to stream upload larger files then
you will need to increase chunk_size.</p>
<p>Increasing the chunk size decreases the accuracy of the progress
statistics displayed with "-P" flag. Rclone treats chunk as sent when
it's buffered by the AWS SDK, when in fact it may still be uploading. A
bigger chunk size means a bigger AWS SDK buffer and progress reporting
more deviating from the truth.</p>
<p>Properties:</p>
<ul>
<li>Config: chunk_size</li>
<li>Env Var: RCLONE_S3_CHUNK_SIZE</li>
<li>Type: SizeSuffix</li>
<li>Default: 5Mi</li>
</ul>
<h4 id="s3-max-upload-parts">--s3-max-upload-parts</h4>
<p>Maximum number of parts in a multipart upload.</p>
<p>This option defines the maximum number of multipart chunks to use
when doing a multipart upload.</p>
<p>This can be useful if a service does not support the AWS S3
specification of 10,000 chunks.</p>
<p>Rclone will automatically increase the chunk size when uploading a
large file of a known size to stay below this number of chunks
limit.</p>
<p>Properties:</p>
<ul>
<li>Config: max_upload_parts</li>
<li>Env Var: RCLONE_S3_MAX_UPLOAD_PARTS</li>
<li>Type: int</li>
<li>Default: 10000</li>
</ul>
<h4 id="s3-copy-cutoff">--s3-copy-cutoff</h4>
<p>Cutoff for switching to multipart copy.</p>
<p>Any files larger than this that need to be server-side copied will be
copied in chunks of this size.</p>
<p>The minimum is 0 and the maximum is 5 GiB.</p>
<p>Properties:</p>
<ul>
<li>Config: copy_cutoff</li>
<li>Env Var: RCLONE_S3_COPY_CUTOFF</li>
<li>Type: SizeSuffix</li>
<li>Default: 4.656Gi</li>
</ul>
<h4 id="s3-disable-checksum">--s3-disable-checksum</h4>
<p>Don't store MD5 checksum with object metadata.</p>
<p>Normally rclone will calculate the MD5 checksum of the input before
uploading it so it can add it to metadata on the object. This is great
for data integrity checking but can cause long delays for large files to
start uploading.</p>
<p>Properties:</p>
<ul>
<li>Config: disable_checksum</li>
<li>Env Var: RCLONE_S3_DISABLE_CHECKSUM</li>
<li>Type: bool</li>
<li>Default: false</li>

<h4 id="s3-shared-credentials-file">--s3-shared-credentials-file</h4>
<p>Path to the shared credentials file.</p>
<p>If env_auth = true then rclone can use a shared credentials file.</p>
<p>If this variable is empty rclone will look for the
"AWS_SHARED_CREDENTIALS_FILE" env variable. If the env value is empty it
will default to the current user's home directory.</p>
<pre><code>Linux/OSX: &quot;$HOME/.aws/credentials&quot;
Windows:   &quot;%USERPROFILE%\.aws\credentials&quot;</code></pre>
<p>Properties:</p>

<li>Type: string</li>
<li>Required: false</li>
</ul>
<h4 id="s3-profile">--s3-profile</h4>
<p>Profile to use in the shared credentials file.</p>
<p>If env_auth = true then rclone can use a shared credentials file.
This variable controls which profile is used in that file.</p>
<p>If empty it will default to the environment variable "AWS_PROFILE" or
"default" if that environment variable is also not set.</p>
<p>Properties:</p>
<ul>
<li>Config: profile</li>
<li>Env Var: RCLONE_S3_PROFILE</li>
<li>Type: string</li>
<li>Required: false</li>

<li>Type: string</li>
<li>Required: false</li>
</ul>
<h4 id="s3-upload-concurrency">--s3-upload-concurrency</h4>
<p>Concurrency for multipart uploads and copies.</p>
<p>This is the number of chunks of the same file that are uploaded
concurrently for multipart uploads and copies.</p>
<p>If you are uploading small numbers of large files over high-speed
links and these uploads do not fully utilize your bandwidth, then
increasing this may help to speed up the transfers.</p>
<p>Properties:</p>
<ul>
<li>Config: upload_concurrency</li>
<li>Env Var: RCLONE_S3_UPLOAD_CONCURRENCY</li>
<li>Type: int</li>
<li>Default: 4</li>
</ul>
<h4 id="s3-force-path-style">--s3-force-path-style</h4>
<p>If true use path style access if false use virtual hosted style.</p>
<p>If this is true (the default) then rclone will use path style access,
if false then rclone will use virtual path style. See <a
href="https://docs.aws.amazon.com/AmazonS3/latest/dev/UsingBucket.html#access-bucket-intro">the
AWS S3 docs</a> for more info.</p>
<p>Some providers (e.g. AWS, Aliyun OSS, Netease COS, or Tencent COS)
require this set to false - rclone will do this automatically based on
the provider setting.</p>
<p>Note that if your bucket isn't a valid DNS name, i.e. has '.' or '_'
in, you'll need to set this to true.</p>
<p>Properties:</p>
<ul>
<li>Config: force_path_style</li>
<li>Env Var: RCLONE_S3_FORCE_PATH_STYLE</li>
<li>Type: bool</li>
<li>Default: true</li>
</ul>
<h4 id="s3-v2-auth">--s3-v2-auth</h4>
<p>If true use v2 authentication.</p>
<p>If this is false (the default) then rclone will use v4
authentication. If it is set then rclone will use v2 authentication.</p>
<p>Use this only if v4 signatures don't work, e.g. pre Jewel/v10
CEPH.</p>
<p>Properties:</p>

<h4 id="s3-leave-parts-on-error">--s3-leave-parts-on-error</h4>
<p>If true avoid calling abort upload on a failure, leaving all
successfully uploaded parts on S3 for manual recovery.</p>
<p>It should be set to true for resuming uploads across different
sessions.</p>
<p>WARNING: Storing parts of an incomplete multipart upload counts
towards space usage on S3 and will add additional costs if not cleaned
up.</p>
<p>Properties:</p>
<ul>
<li>Config: leave_parts_on_error</li>
<li>Env Var: RCLONE_S3_LEAVE_PARTS_ON_ERROR</li>
<li>Provider: AWS</li>
<li>Type: bool</li>
<li>Default: false</li>
</ul>
<h4 id="s3-list-chunk">--s3-list-chunk</h4>
<p>Size of listing chunk (response list for each ListObject S3
request).</p>
<p>This option is also known as "MaxKeys", "max-items", or "page-size"
from the AWS S3 specification. Most services truncate the response list
to 1000 objects even if requested more than that. In AWS S3 this is a
global maximum and cannot be changed, see <a
href="https://docs.aws.amazon.com/cli/latest/reference/s3/ls.html">AWS
S3</a>. In Ceph, this can be increased with the "rgw list buckets max
chunk" option.</p>
<p>Properties:</p>
<ul>
<li>Config: list_chunk</li>
<li>Env Var: RCLONE_S3_LIST_CHUNK</li>
<li>Type: int</li>
<li>Default: 1000</li>
</ul>
<h4 id="s3-list-version">--s3-list-version</h4>
<p>Version of ListObjects to use: 1,2 or 0 for auto.</p>
<p>When S3 originally launched it only provided the ListObjects call to
enumerate objects in a bucket.</p>
<p>However in May 2016 the ListObjectsV2 call was introduced. This is
much higher performance and should be used if at all possible.</p>
<p>If set to the default, 0, rclone will guess according to the provider
set which list objects method to call. If it guesses wrong, then it may
be set manually here.</p>
<p>Properties:</p>
<ul>
<li>Config: list_version</li>
<li>Env Var: RCLONE_S3_LIST_VERSION</li>
<li>Type: int</li>
<li>Default: 0</li>
</ul>
<h4 id="s3-list-url-encode">--s3-list-url-encode</h4>
<p>Whether to url encode listings: true/false/unset</p>
<p>Some providers support URL encoding listings and where this is
available this is more reliable when using control characters in file
names. If this is set to unset (the default) then rclone will choose
according to the provider setting what to apply, but you can override
rclone's choice here.</p>
<p>Properties:</p>
<ul>

<h4 id="s3-no-check-bucket">--s3-no-check-bucket</h4>
<p>If set, don't attempt to check the bucket exists or create it.</p>
<p>This can be useful when trying to minimise the number of transactions
rclone does if you know the bucket exists already.</p>
<p>It can also be needed if the user you are using does not have bucket
creation permissions. Before v1.52.0 this would have passed silently due
to a bug.</p>
<p>Properties:</p>
<ul>
<li>Config: no_check_bucket</li>
<li>Env Var: RCLONE_S3_NO_CHECK_BUCKET</li>
<li>Type: bool</li>
<li>Default: false</li>
</ul>
<h4 id="s3-no-head">--s3-no-head</h4>
<p>If set, don't HEAD uploaded objects to check integrity.</p>
<p>This can be useful when trying to minimise the number of transactions
rclone does.</p>
<p>Setting it means that if rclone receives a 200 OK message after
uploading an object with PUT then it will assume that it got uploaded
properly.</p>
<p>In particular it will assume:</p>
<ul>
<li>the metadata, including modtime, storage class and content type was
as uploaded</li>
<li>the size was as uploaded</li>
</ul>
<p>It reads the following items from the response for a single part
PUT:</p>
<ul>
<li>the MD5SUM</li>
<li>The uploaded date</li>
</ul>
<p>For multipart uploads these items aren't read.</p>
<p>If an source object of unknown length is uploaded then rclone
<strong>will</strong> do a HEAD request.</p>
<p>Setting this flag increases the chance for undetected upload
failures, in particular an incorrect size, so it isn't recommended for
normal operation. In practice the chance of an undetected upload failure
is very small even with this flag.</p>
<p>Properties:</p>
<ul>
<li>Config: no_head</li>
<li>Env Var: RCLONE_S3_NO_HEAD</li>

<h4 id="s3-disable-http2">--s3-disable-http2</h4>
<p>Disable usage of http2 for S3 backends.</p>
<p>There is currently an unsolved issue with the s3 (specifically minio)
backend and HTTP/2. HTTP/2 is enabled by default for the s3 backend but
can be disabled here. When the issue is solved this flag will be
removed.</p>
<p>See: https://github.com/rclone/rclone/issues/4673,

<li>Default: false</li>
</ul>
<h4 id="s3-download-url">--s3-download-url</h4>
<p>Custom endpoint for downloads. This is usually set to a CloudFront
CDN URL as AWS S3 offers cheaper egress for data downloaded through the
CloudFront network.</p>
<p>Properties:</p>
<ul>
<li>Config: download_url</li>
<li>Env Var: RCLONE_S3_DOWNLOAD_URL</li>
<li>Type: string</li>
<li>Required: false</li>
</ul>
<h4 id="s3-directory-markers">--s3-directory-markers</h4>
<p>Upload an empty object with a trailing slash when a new directory is
created</p>
<p>Empty folders are unsupported for bucket based remotes, this option
creates an empty object ending with "/", to persist the folder.</p>
<p>Properties:</p>
<ul>
<li>Config: directory_markers</li>
<li>Env Var: RCLONE_S3_DIRECTORY_MARKERS</li>
<li>Type: bool</li>
<li>Default: false</li>
</ul>
<h4 id="s3-use-multipart-etag">--s3-use-multipart-etag</h4>
<p>Whether to use ETag in multipart uploads for verification</p>
<p>This should be true, false or left unset to use the default for the
provider.</p>
<p>Properties:</p>
<ul>
<li>Config: use_multipart_etag</li>
<li>Env Var: RCLONE_S3_USE_MULTIPART_ETAG</li>
<li>Type: Tristate</li>
<li>Default: unset</li>
</ul>
<h4 id="s3-use-unsigned-payload">--s3-use-unsigned-payload</h4>
<p>Whether to use an unsigned payload in PutObject</p>
<p>Rclone has to avoid the AWS SDK seeking the body when calling
PutObject. The AWS provider can add checksums in the trailer to avoid
seeking but other providers can't.</p>
<p>This should be true, false or left unset to use the default for the
provider.</p>
<p>Properties:</p>
<ul>
<li>Config: use_unsigned_payload</li>
<li>Env Var: RCLONE_S3_USE_UNSIGNED_PAYLOAD</li>
<li>Type: Tristate</li>
<li>Default: unset</li>
</ul>
<h4 id="s3-use-presigned-request">--s3-use-presigned-request</h4>
<p>Whether to use a presigned request or PutObject for single part
uploads</p>
<p>If this is false rclone will use PutObject from the AWS SDK to upload
an object.</p>
<p>Versions of rclone &lt; 1.59 use presigned requests to upload a
single part object and setting this flag to true will re-enable that
functionality. This shouldn't be necessary except in exceptional
circumstances or for testing.</p>
<p>Properties:</p>
<ul>
<li>Config: use_presigned_request</li>
<li>Env Var: RCLONE_S3_USE_PRESIGNED_REQUEST</li>
<li>Type: bool</li>
<li>Default: false</li>
</ul>
<h4
id="s3-use-data-integrity-protections">--s3-use-data-integrity-protections</h4>
<p>If true use AWS S3 data integrity protections.</p>
<p>See <a

<h4 id="s3-versions">--s3-versions</h4>
<p>Include old versions in directory listings.</p>
<p>Properties:</p>
<ul>
<li>Config: versions</li>
<li>Env Var: RCLONE_S3_VERSIONS</li>
<li>Type: bool</li>
<li>Default: false</li>
</ul>
<h4 id="s3-version-at">--s3-version-at</h4>
<p>Show file versions as they were at the specified time.</p>
<p>The parameter should be a date, "2006-01-02", datetime "2006-01-02
15:04:05" or a duration for that long ago, eg "100d" or "1h".</p>
<p>Note that when using this no file write operations are permitted, so
you can't upload files or delete them.</p>
<p>See <a href="https://rclone.org/docs/#time-options">the time option
docs</a> for valid formats.</p>
<p>Properties:</p>
<ul>
<li>Config: version_at</li>
<li>Env Var: RCLONE_S3_VERSION_AT</li>
<li>Type: Time</li>
<li>Default: off</li>
</ul>
<h4 id="s3-version-deleted">--s3-version-deleted</h4>
<p>Show deleted file markers when using versions.</p>
<p>This shows deleted file markers in the listing when using versions.
These will appear as 0 size files. The only operation which can be
performed on them is deletion.</p>
<p>Deleting a delete marker will reveal the previous version.</p>
<p>Deleted files will always show with a timestamp.</p>
<p>Properties:</p>
<ul>
<li>Config: version_deleted</li>
<li>Env Var: RCLONE_S3_VERSION_DELETED</li>
<li>Type: bool</li>
<li>Default: false</li>
</ul>
<h4 id="s3-decompress">--s3-decompress</h4>
<p>If set this will decompress gzip encoded objects.</p>
<p>It is possible to upload objects to S3 with "Content-Encoding: gzip"
set. Normally rclone will download these files as compressed
objects.</p>
<p>If this flag is set then rclone will decompress these files with
"Content-Encoding: gzip" as they are received. This means that rclone
can't check the size and hash but the file contents will be
decompressed.</p>
<p>Properties:</p>
<ul>
<li>Config: decompress</li>
<li>Env Var: RCLONE_S3_DECOMPRESS</li>
<li>Type: bool</li>
<li>Default: false</li>
</ul>
<h4 id="s3-might-gzip">--s3-might-gzip</h4>
<p>Set this if the backend might gzip objects.</p>
<p>Normally providers will not alter objects when they are downloaded.
If an object was not uploaded with <code>Content-Encoding: gzip</code>
then it won't be set on download.</p>
<p>However some providers may gzip objects even if they weren't uploaded
with <code>Content-Encoding: gzip</code> (eg Cloudflare).</p>
<p>A symptom of this would be receiving errors like</p>
<pre><code>ERROR corrupted on transfer: sizes differ NNN vs MMM</code></pre>
<p>If you set this flag and rclone downloads an object with
Content-Encoding: gzip set and chunked transfer encoding, then rclone
will decompress the object on the fly.</p>
<p>If this is set to unset (the default) then rclone will choose
according to the provider setting what to apply, but you can override
rclone's choice here.</p>
<p>Properties:</p>
<ul>
<li>Config: might_gzip</li>
<li>Env Var: RCLONE_S3_MIGHT_GZIP</li>
<li>Type: Tristate</li>
<li>Default: unset</li>
</ul>
<h4 id="s3-use-accept-encoding-gzip">--s3-use-accept-encoding-gzip</h4>
<p>Whether to send <code>Accept-Encoding: gzip</code> header.</p>
<p>By default, rclone will append <code>Accept-Encoding: gzip</code> to
the request to download compressed objects whenever possible.</p>
<p>However some providers such as Google Cloud Storage may alter the
HTTP headers, breaking the signature of the request.</p>
<p>A symptom of this would be receiving errors like</p>
<pre><code>SignatureDoesNotMatch: The request signature we calculated does not match the signature you provided.</code></pre>
<p>In this case, you might want to try disabling this option.</p>
<p>Properties:</p>
<ul>
<li>Config: use_accept_encoding_gzip</li>
<li>Env Var: RCLONE_S3_USE_ACCEPT_ENCODING_GZIP</li>
<li>Type: Tristate</li>
<li>Default: unset</li>

<li>Env Var: RCLONE_S3_NO_SYSTEM_METADATA</li>
<li>Type: bool</li>
<li>Default: false</li>
</ul>
<h4 id="s3-sts-endpoint">--s3-sts-endpoint</h4>
<p>Endpoint for STS (deprecated).</p>
<p>Leave blank if using AWS to use the default endpoint for the
region.</p>
<p>Properties:</p>
<ul>
<li>Config: sts_endpoint</li>
<li>Env Var: RCLONE_S3_STS_ENDPOINT</li>
<li>Provider: AWS</li>
<li>Type: string</li>
<li>Required: false</li>
</ul>
<h4 id="s3-use-already-exists">--s3-use-already-exists</h4>
<p>Set if rclone should report BucketAlreadyExists errors on bucket
creation.</p>
<p>At some point during the evolution of the s3 protocol, AWS started
returning an <code>AlreadyOwnedByYou</code> error when attempting to
create a bucket that the user already owned, rather than a
<code>BucketAlreadyExists</code> error.</p>
<p>Unfortunately exactly what has been implemented by s3 clones is a
little inconsistent, some return <code>AlreadyOwnedByYou</code>, some
return <code>BucketAlreadyExists</code> and some return no error at
all.</p>
<p>This is important to rclone because it ensures the bucket exists by
creating it on quite a lot of operations (unless
<code>--s3-no-check-bucket</code> is used).</p>
<p>If rclone knows the provider can return
<code>AlreadyOwnedByYou</code> or returns no error then it can report
<code>BucketAlreadyExists</code> errors when the user attempts to create
a bucket not owned by them. Otherwise rclone ignores the
<code>BucketAlreadyExists</code> error which can lead to confusion.</p>
<p>This should be automatically set correctly for all providers rclone
knows about - please make a bug report if not.</p>
<p>Properties:</p>
<ul>
<li>Config: use_already_exists</li>
<li>Env Var: RCLONE_S3_USE_ALREADY_EXISTS</li>
<li>Type: Tristate</li>
<li>Default: unset</li>
</ul>
<h4 id="s3-use-multipart-uploads">--s3-use-multipart-uploads</h4>
<p>Set if rclone should use multipart uploads.</p>
<p>You can change this if you want to disable the use of multipart
uploads. This shouldn't be necessary in normal operation.</p>
<p>This should be automatically set correctly for all providers rclone
knows about - please make a bug report if not.</p>
<p>Properties:</p>

</ul>
<h4 id="s3-use-x-id">--s3-use-x-id</h4>
<p>Set if rclone should add x-id URL parameters.</p>
<p>You can change this if you want to disable the AWS SDK from adding
x-id URL parameters.</p>
<p>This shouldn't be necessary in normal operation.</p>
<p>This should be automatically set correctly for all providers rclone
knows about - please make a bug report if not.</p>

<h4 id="s3-sign-accept-encoding">--s3-sign-accept-encoding</h4>
<p>Set if rclone should include Accept-Encoding as part of the
signature.</p>
<p>You can change this if you want to stop rclone including
Accept-Encoding as part of the signature.</p>
<p>This shouldn't be necessary in normal operation.</p>
<p>This should be automatically set correctly for all providers rclone
knows about - please make a bug report if not.</p>
<p>Properties:</p>

<li>Type: Tristate</li>
<li>Default: unset</li>
</ul>
<h4 id="s3-directory-bucket">--s3-directory-bucket</h4>
<p>Set to use AWS Directory Buckets</p>
<p>If you are using an AWS Directory Bucket then set this flag.</p>
<p>This will ensure no <code>Content-Md5</code> headers are sent and
ensure <code>ETag</code> headers are not interpreted as MD5 sums.
<code>X-Amz-Meta-Md5chksum</code> will be set on all objects whether
single or multipart uploaded.</p>
<p>This also sets <code>no_check_bucket = true</code>.</p>
<p>Note that Directory Buckets do not support:</p>
<ul>
<li>Versioning</li>
<li><code>Content-Encoding: gzip</code></li>
</ul>
<p>Rclone limitations with Directory Buckets:</p>
<ul>
<li>rclone does not support creating Directory Buckets with
<code>rclone mkdir</code></li>
<li>... or removing them with <code>rclone rmdir</code> yet</li>
<li>Directory Buckets do not appear when doing <code>rclone lsf</code>
at the top level.</li>
<li>Rclone can't remove auto created directories yet. In theory this
should work with <code>directory_markers = true</code> but it
doesn't.</li>
<li>Directories don't seem to appear in recursive (ListR) listings.</li>

<h3 id="cleanup-2">cleanup</h3>
<p>Remove unfinished multipart uploads.</p>
<pre class="console"><code>rclone backend cleanup remote: [options] [&lt;arguments&gt;+]</code></pre>
<p>This command removes unfinished multipart uploads of age greater than
max-age which defaults to 24 hours.</p>
<p>Note that you can use --interactive/-i or --dry-run with this command
to see what it would do.</p>
<p>Usage examples:</p>
<pre class="console"><code>rclone backend cleanup s3:bucket/path/to/object
rclone backend cleanup -o max-age=7w s3:bucket/path/to/object</code></pre>
<p>Durations are parsed as per the rest of rclone, 2h, 7d, 7w etc.</p>
<p>Options:</p>
<ul>
<li>"max-age": Max age of upload to delete.</li>
</ul>
<h3 id="cleanup-hidden">cleanup-hidden</h3>
<p>Remove old versions of files.</p>
<pre class="console"><code>rclone backend cleanup-hidden remote: [options] [&lt;arguments&gt;+]</code></pre>
<p>This command removes any old hidden versions of files on a versions
enabled bucket.</p>
<p>Note that you can use --interactive/-i or --dry-run with this command
to see what it would do.</p>
<p>Usage example:</p>
<pre class="console"><code>rclone backend cleanup-hidden s3:bucket/path/to/dir</code></pre>
<h3 id="versioning">versioning</h3>
<p>Set/get versioning support for a bucket.</p>
<pre class="console"><code>rclone backend versioning remote: [options] [&lt;arguments&gt;+]</code></pre>
<p>This command sets versioning support if a parameter is passed and
then returns the current versioning status for the bucket supplied.</p>
<p>Usage examples:</p>
<pre class="console"><code>rclone backend versioning s3:bucket # read status only
rclone backend versioning s3:bucket Enabled
rclone backend versioning s3:bucket Suspended</code></pre>
<p>It may return "Enabled", "Suspended" or "Unversioned". Note that once
versioning has been enabled the status can't be set back to
"Unversioned".</p>
<h3 id="set">set</h3>
<p>Set command for updating the config parameters.</p>
<pre class="console"><code>rclone backend set remote: [options] [&lt;arguments&gt;+]</code></pre>
<p>This set command can be used to update the config parameters for a
running s3 backend.</p>
<p>Usage examples:</p>
<pre class="console"><code>rclone backend set s3: [-o opt_name=opt_value] [-o opt_name2=opt_value2]
rclone rc backend/command command=set fs=s3: [-o opt_name=opt_value] [-o opt_name2=opt_value2]
rclone rc backend/command command=set fs=s3: -o session_token=X -o access_key_id=X -o secret_access_key=X</code></pre>
<p>The option keys are named as they are in the config file.</p>
<p>This rebuilds the connection to the s3 backend when it is called with
the new parameters. Only new parameters need be passed as the values
will default to those currently in use.</p>
<p>It doesn't return anything.</p>
<!-- autogenerated options stop -->
<h3 id="anonymous-access">Anonymous access to public buckets</h3>
<p>If you want to use rclone to access a public bucket, configure with a
blank <code>access_key_id</code> and <code>secret_access_key</code>.
Your config should end up looking like this:</p>
<div class="sourceCode" id="cb993"><pre
class="sourceCode ini"><code class="sourceCode ini"><span id="cb993-1"><a href="#cb993-1" aria-hidden="true" tabindex="-1"></a><span class="kw">[anons3]</span></span>

<p>Then use it as normal with the name of the public bucket, e.g.</p>
<pre class="console"><code>rclone lsd anons3:1000genomes</code></pre>
<p>You will be able to list and copy data but not upload it.</p>
<p>You can also do this entirely on the command line</p>
<pre class="console"><code>rclone lsd :s3,provider=AWS:1000genomes</code></pre>

Buckets</a> are supported.</p>
<p>You will need to set the <code>directory_buckets = true</code> config
parameter or use <code>--s3-directory-buckets</code>.</p>
<p>Note that rclone cannot yet:</p>
<ul>
<li>Create directory buckets</li>
<li>List directory buckets</li>
</ul>
<p>See <a href="#s3-directory-buckets">the --s3-directory-buckets

<h3 id="aws-snowball-edge">AWS Snowball Edge</h3>
<p><a href="https://aws.amazon.com/snowball/">AWS Snowball</a> is a
hardware appliance used for transferring bulk data back to AWS. Its main
software interface is S3 object storage.</p>
<p>To use rclone with AWS Snowball Edge devices, configure as standard
for an 'S3 Compatible Service'.</p>
<p>If using rclone pre v1.59 be sure to set
<code>upload_cutoff = 0</code> otherwise you will run into
authentication header issues as the snowball device does not support
query parameter based authentication.</p>
<p>With rclone v1.59 or later setting <code>upload_cutoff</code> should
not be necessary.</p>

<p>If you are using an older version of CEPH (e.g. 10.2.x Jewel) and a
version of rclone before v1.59 then you may need to supply the parameter
<code>--s3-upload-cutoff 0</code> or put this in the config file as
<code>upload_cutoff 0</code> to work around a bug which causes uploading
of small files to fail.</p>
<p>Note also that Ceph sometimes puts <code>/</code> in the passwords it
gives users. If you read the secret access key using the command line
tools you will get a JSON blob with the <code>/</code> escaped as
<code>\/</code>. Make sure you only write <code>/</code> in the secret
access key.</p>
<p>Eg the dump from Ceph looks something like this (irrelevant keys
removed).</p>

what AWS does. If this is causing a problem then upload the files with

works the same way as on S3 by accepting the "GLACIER"

<h4 id="backend-quirks">Backend quirks</h4>
<ul>
<li><code>--chunk-size</code> is forced to be 64 MiB or greater. This
will use more memory than the default of 5 MiB.</li>
<li>Server side copy is disabled as it isn't currently supported in the
gateway.</li>
<li>GetTier and SetTier are not supported.</li>
</ul>
<h4 id="backend-bugs">Backend bugs</h4>
<p>Due to <a href="https://github.com/storj/gateway-mt/issues/39">issue
#39</a> uploading multipart files via the S3 gateway causes them to lose
their metadata. For rclone's purpose this means that the modification
time is not stored, nor is any MD5SUM (if one is available from the
source).</p>
<p>This has the following consequences:</p>
<ul>
<li>Using <code>rclone rcat</code> will fail as the metadata doesn't
match after upload</li>
<li>Uploading files with <code>rclone mount</code> will fail for the
same reason
<ul>
<li>This can worked around by using <code>--vfs-cache-mode writes</code>
or <code>--vfs-cache-mode full</code> or setting
<code>--s3-upload-cutoff</code> large</li>
</ul></li>
<li>Files uploaded via a multipart upload won't have their modtimes
<ul>
<li>This will mean that <code>rclone sync</code> will likely keep trying
to upload files bigger than <code>--s3-upload-cutoff</code></li>
<li>This can be worked around with <code>--checksum</code> or
<code>--size-only</code> or setting <code>--s3-upload-cutoff</code>
large</li>
<li>The maximum value for <code>--s3-upload-cutoff</code> is 5GiB
though</li>
</ul></li>
</ul>
<p>One general purpose workaround is to set
<code>--s3-upload-cutoff 5G</code>. This means that rclone will upload
files smaller than 5GiB as single parts. Note that this can be set in
the config file with <code>upload_cutoff = 5G</code> or configured in
the advanced settings. If you regularly transfer files larger than 5G
then using <code>--checksum</code> or <code>--size-only</code> in
<code>rclone sync</code> is the recommended workaround.</p>
<h4 id="comparison-with-the-native-protocol">Comparison with the native
protocol</h4>
<p>Use the <a href="/storj">the native protocol</a> to take advantage of
client-side encryption as well as to achieve the best possible download
performance. Uploads will be erasure-coded locally, thus a 1gb upload
will result in 2.68gb of data being uploaded to storage nodes across the
network.</p>
<p>Use this backend and the S3 compatible Hosted Gateway to increase
upload performance and reduce the load on your systems and network.
Uploads will be encrypted and erasure-coded server-side, thus a 1GB
upload will result in only in 1GB of data being uploaded to storage
nodes across the network.</p>

<h2 id="memory">Memory usage</h2>
<p>The most common cause of rclone using lots of memory is a single
directory with millions of files in. Despite s3 not really having the
concepts of directories, rclone does the sync on a directory by
directory basis to be compatible with normal filing systems.</p>
<p>Rclone loads each directory into memory as rclone objects. Each
rclone object takes 0.5k-1k of memory, so approximately 1GB per
1,000,000 files, and the sync for that directory does not begin until it
is entirely loaded in memory. So the sync can take a long time to start
for large directories.</p>
<p>To sync a directory with 100,000,000 files in you would need
approximately 100 GB of memory. At some point the amount of memory
becomes difficult to provide so there is <a
href="https://github.com/rclone/rclone/wiki/Big-syncs-with-millions-of-files">a
workaround for this</a> which involves a bit of scripting.</p>
<p>At some point rclone will gain a sync mode which is effectively this
workaround but built in to rclone.</p>
<h2 id="limitations-6">Limitations</h2>
<p><code>rclone about</code> is not supported by the S3 backend.
Backends without this capability cannot determine free space for an
rclone mount or use policy <code>mfs</code> (most free space) as a
member of an rclone union remote.</p>
<p>See <a href="https://rclone.org/overview/#optional-features">List of
backends that do not support rclone about</a> and <a
href="https://rclone.org/commands/rclone_about/">rclone about</a>.</p>
<h1 id="archive">Archive</h1>
<p>The Archive backend allows read only access to the content of archive
files on cloud storage without downloading the complete archive. This
means you could mount a large archive file and use only the parts of it
your application requires, rather than having to extract it.</p>
<p>The archive files are recognised by their extension.</p>
<table>
<thead>

<th>Archive</th>

</tr>
</thead>
<tbody>
<tr class="odd">
<td>Zip</td>
<td><code>.zip</code></td>
</tr>
<tr class="even">
<td>Squashfs</td>
<td><code>.sqfs</code></td>
</tr>
</tbody>
</table>
<p>The supported archive file types are cloud friendly - a single file
can be found and downloaded without downloading the whole archive.</p>
<p>If you just want to create, list or extract archives and don't want
to mount them then you may find the <code>rclone archive</code> commands
more convenient.</p>
<ul>
<li><a href="https://rclone.org/commands/rclone_archive_create/">rclone
archive create</a></li>
<li><a href="https://rclone.org/commands/rclone_archive_list/">rclone
archive list</a></li>
<li><a href="https://rclone.org/commands/rclone_archive_extract/">rclone
archive extract</a></li>
</ul>
<p>These commands supports a wider range of non cloud friendly archives
(but not squashfs) but can't be used for <code>rclone mount</code> or
any other rclone commands (eg <code>rclone check</code>).</p>
<h2 id="configuration-3">Configuration</h2>
<p>This backend is best used without configuration.</p>
<p>Use it by putting the string <code>:archive:</code> in front of
another remote, say <code>remote:dir</code> to make
<code>:archive:remote:dir</code>.</p>
<p>Any archives in <code>remote:dir</code> will become directories and
any files may be read out of them individually.</p>
<p>For example</p>
<pre><code>$ rclone lsf s3:rclone/dir
100files.sqfs
100files.zip</code></pre>
<p>Note that <code>100files.zip</code> and <code>100files.sqfs</code>
are now directories:</p>
<pre><code>$ rclone lsf :archive:s3:rclone/dir
100files.sqfs/
100files.zip/</code></pre>
<p>Which we can look inside:</p>
<pre><code>$ rclone lsf :archive:s3:rclone/dir/100files.zip/

vibat/

xade
zilupot</code></pre>
<p>Files not in an archive can be read and written as normal. Files in
an archive can only be read.</p>
<p>The archive backend can also be used in a configuration file. Use the
<code>remote</code> variable to point to the destination of the
archive.</p>
<pre><code>[remote]
type = archive
remote = s3:rclone/dir/100files.zip</code></pre>
<p>Gives</p>
<pre><code>$ rclone lsf remote:

<h2 id="hashes-1">Hashes</h2>
<p>Which hash is supported depends on the archive type. Zip files use
CRC32, Squashfs don't support any hashes. For example:</p>
<pre><code>$ rclone hashsum crc32 :archive:s3:rclone/dir/100files.zip/

<h2 id="zip">Zip</h2>
<p>The <a href="https://en.wikipedia.org/wiki/ZIP_(file_format)">Zip
file format</a> is a widely used archive format that bundles one or more
files and folders into a single file, primarily for easier storage or
transmission. It typically uses compression (most commonly the DEFLATE
algorithm) to reduce the overall size of the archived content. Zip files
are supported natively by most modern operating systems.</p>
<p>Rclone does not support the following advanced features of Zip
files:</p>
<ul>
<li>Splitting large archives into smaller parts</li>
<li>Password protection</li>
<li>Zstd compression</li>
</ul>
<h2 id="squashfs">Squashfs</h2>
<p>Squashfs is a compressed, read-only file system format primarily used
in Linux-based systems. It's designed to compress entire file systems
(including files, directories, and metadata) into a single archive file,
which can then be mounted and read directly, appearing as a normal
directory structure. Because it's read-only and highly compressed,
Squashfs is ideal for live CDs/USBs, embedded devices with limited
storage, and software package distribution, as it saves space and
ensures the integrity of the original files.</p>
<p>Rclone supports the following squashfs compression formats:</p>
<ul>
<li><code>Gzip</code></li>
<li><code>Lzma</code></li>
<li><code>Xz</code></li>
<li><code>Zstd</code></li>
</ul>
<p>These are not yet working:</p>
<ul>
<li><code>Lzo</code> - Not yet supported</li>
<li><code>Lz4</code> - Broken with "error decompressing: lz4: bad magic
number"</li>
</ul>
<p>Rclone works fastest with large squashfs block sizes. For
example:</p>
<pre><code>mksquashfs 100files 100files.sqfs -comp zstd -b 1M</code></pre>
<h2 id="limitations-7">Limitations</h2>
<p>Files in the archive backend are read only. It isn't possible to
create archives with the archive backend yet. However you
<strong>can</strong> create archives with <a
href="https://rclone.org/commands/rclone_archive_create/">rclone archive
create</a>.</p>
<p>Only <code>.zip</code> and <code>.sqfs</code> archives are supported
as these are the only common archiving formats which make it easy to
read directory listings from the archive without downloading the whole
archive.</p>
<p>Internally the archive backend uses the VFS to access files. It isn't
possible to configure the internal VFS yet which might be useful.</p>
<h2 id="archive-formats">Archive Formats</h2>
<p>Here's a table rating common archive formats on their Cloud
Optimization which is based on their ability to access a single file
without reading the entire archive.</p>
<p>This capability depends on whether the format has a central
<strong>index</strong> (or "table of contents") that a program can read
first to find the exact location of a specific file.</p>

<td style="text-align: left;"><strong>ZIP</strong></td>
<td style="text-align: left;"><code>.zip</code></td>
<td style="text-align: left;"><strong>Excellent</strong></td>
<td style="text-align: left;"><strong>Zip files have an index</strong>
(the "central directory") stored at the <em>end</em> of the file. A
program can seek to the end, read the index to find a file's location
and size, and then seek directly to that file's data to extract it.</td>

<td style="text-align: left;"><code>.squashfs</code>,
<code>.sqfs</code>, <code>.sfs</code></td>
<td style="text-align: left;"><strong>Excellent</strong></td>
<td style="text-align: left;">This is a compressed read-only
<em>filesystem image</em>, not just an archive. It is
<strong>specifically designed for random access</strong>. It uses
metadata and index tables to allow the system to find and decompress
individual files or data blocks on demand.</td>
</tr>
<tr class="odd">
<td style="text-align: left;"><strong>ISO Image</strong></td>
<td style="text-align: left;"><code>.iso</code></td>
<td style="text-align: left;"><strong>Excellent</strong></td>
<td style="text-align: left;">Like SquashFS, this is a <em>filesystem
image</em> (for optical media). It contains a filesystem (like ISO 9660
or UDF) with a <strong>table of contents at a known location</strong>,
allowing for direct access to any file without reading the whole
disk.</td>
</tr>
<tr class="even">
<td style="text-align: left;"><strong>RAR</strong></td>
<td style="text-align: left;"><code>.rar</code></td>
<td style="text-align: left;"><strong>Good</strong></td>
<td style="text-align: left;">RAR supports "non-solid" and "solid"
modes. In the common <strong>non-solid</strong> mode, files are
compressed separately, and an index allows for easy single-file
extraction (like ZIP). In "solid" mode, this rating would be "Very
Poor."</td>
</tr>
<tr class="odd">
<td style="text-align: left;"><strong>7z</strong></td>
<td style="text-align: left;"><code>.7z</code></td>
<td style="text-align: left;"><strong>Poor</strong></td>
<td style="text-align: left;">By default, 7z uses "solid" archives to
maximize compression. This compresses files as one continuous stream. To
extract a file from the middle, all preceding files must be decompressed
first. (If explicitly created as "non-solid," its rating would be
"Excellent").</td>
</tr>
<tr class="even">
<td style="text-align: left;"><strong>tar</strong></td>
<td style="text-align: left;"><code>.tar</code></td>
<td style="text-align: left;"><strong>Poor</strong></td>
<td style="text-align: left;">"Tape Archive" is a <em>streaming</em>
format with <strong>no central index</strong>. To find a file, you must
read the archive from the beginning, checking each file header one by
one until you find the one you want. This is slow but doesn't require
decompressing data.</td>
</tr>
<tr class="odd">
<td style="text-align: left;"><strong>Gzipped Tar</strong></td>
<td style="text-align: left;"><code>.tar.gz</code>,
<code>.tgz</code></td>
<td style="text-align: left;"><strong>Very Poor</strong></td>
<td style="text-align: left;">This is a <code>tar</code> file (already
"Poor") compressed with <code>gzip</code> as a <strong>single,
non-seekable stream</strong>. You cannot seek. To get <em>any</em> file,
you must decompress the <em>entire</em> archive from the beginning up to
that file.</td>
</tr>
<tr class="even">
<td style="text-align: left;"><strong>Bzipped/XZ Tar</strong></td>
<td style="text-align: left;"><code>.tar.bz2</code>,
<code>.tar.xz</code></td>
<td style="text-align: left;"><strong>Very Poor</strong></td>
<td style="text-align: left;">This is the same principle as
<code>tar.gz</code>. The entire archive is one large compressed block,
making random access impossible.</td>

<h2 id="ideas-for-improvements">Ideas for improvements</h2>
<p>It would be possible to add ISO support fairly easily as the library
we use (<a href="https://github.com/diskfs/go-diskfs/">go-diskfs</a>)
supports it. We could also add <code>ext4</code> and <code>fat32</code>
the same way, however in my experience these are not very common as
files so probably not worth it. Go-diskfs can also read partitions which
we could potentially take advantage of.</p>
<p>It would be possible to add write support, but this would only be for
creating new archives, not for updating existing archives.</p>

<p>B2 supports multiple <a

Keys for different access permission to B2 Buckets</a>.</p>
<p>You can use these with rclone too; you will need to use rclone
version 1.43 or later.</p>
<p>Follow Backblaze's docs to create an Application Key with the
required permission and add the <code>applicationKeyId</code> as the
<code>account</code> and the <code>Application Key</code> itself as the
<code>key</code>.</p>
<p>Note that you must put the <em>applicationKeyId</em> as the
<code>account</code> – you can't use the master Account ID. If you try
then B2 will return 401 errors.</p>
<h3 id="fast-list-1">--fast-list</h3>
<p>This remote supports <code>--fast-list</code> which allows you to use
fewer transactions in exchange for more memory. See the <a
href="https://rclone.org/docs/#fast-list">rclone docs</a> for more
details.</p>
<h3 id="modification-times-3">Modification times</h3>
<p>The modification time is stored as metadata on the object as
<code>X-Bz-Info-src_last_modified_millis</code> as milliseconds since
1970-01-01 in the Backblaze standard. Other tools should be able to use
this as a modified time.</p>
<p>Modified times are used in syncing and are fully supported. Note that
if a modification time needs to be updated on an object then it will
create a new version of the object.</p>
<h3 id="restricted-filename-characters-2">Restricted filename
characters</h3>
<p>In addition to the <a

</tbody>
</table>
<p>Invalid UTF-8 bytes will also be <a
href="https://rclone.org/overview/#invalid-utf8">replaced</a>, as they
can't be used in JSON strings.</p>
<p>Note that in 2020-05 Backblaze started allowing  characters in file
names. Rclone hasn't changed its encoding as this could cause syncs to
re-transfer files. If you want rclone not to replace  then see the
<code>--b2-encoding</code> flag below and remove the
<code>BackSlash</code> from the string. This can be set in the
config.</p>
<h3 id="sha1-checksums">SHA1 checksums</h3>
<p>The SHA1 checksums of the files are checked on upload and download
and will be used in the syncing process.</p>
<p>Large files (bigger than the limit in
<code>--b2-upload-cutoff</code>) which are uploaded in chunks will store
their SHA1 on the object as <code>X-Bz-Info-large_file_sha1</code> as
recommended by Backblaze.</p>
<p>For a large file to be uploaded with an SHA1 checksum, the source
needs to support SHA1 checksums. The local disk supports SHA1 checksums
so large file transfers from local disk will have an SHA1. See <a
href="https://rclone.org/overview/#features">the overview</a> for
exactly which remotes support SHA1.</p>
<p>Sources which don't support SHA1, in particular <code>crypt</code>
will upload large files without SHA1 checksums. This may be fixed in the
future (see <a
href="https://github.com/rclone/rclone/issues/1767">#1767</a>).</p>
<p>Files sizes below <code>--b2-upload-cutoff</code> will always have an
SHA1 regardless of the source.</p>
<h3 id="transfers">Transfers</h3>
<p>Backblaze recommends that you do lots of transfers simultaneously for
maximum speed. In tests from my SSD equipped laptop the optimum setting
is about <code>--transfers 32</code> though higher numbers may be used
for a slight speed improvement. The optimum number for you may vary
depending on your hardware, how big the files are, how much you want to
load your computer, etc. The default of <code>--transfers 4</code> is
definitely too low for Backblaze B2 though.</p>
<p>Note that uploading big files (bigger than 200 MiB by default) will
use a 96 MiB RAM buffer by default. There can be at most
<code>--transfers</code> of these in use at any moment, so this sets the
upper limit on the memory used.</p>
<h3 id="versions-1">Versions</h3>
<p>The default setting of B2 is to keep old versions of files. This
means when rclone uploads a new version of a file it creates a <a
href="https://www.backblaze.com/docs/cloud-storage-file-versions">new
version of it</a>. Likewise when you delete a file, the old version will
be marked hidden and still be available.</p>
<p>Whether B2 keeps old versions of files or not can be adjusted on a
per bucket basis using the "Lifecycle settings" on the B2 control panel
or when creating the bucket using the <a
href="#b2-lifecycle">--b2-lifecycle</a> flag or after creation using the
<a href="#lifecycle">rclone backend lifecycle</a> command.</p>
<p>You may opt in to a "hard delete" of files with the
<code>--b2-hard-delete</code> flag which permanently removes files on
deletion instead of hiding them.</p>
<p>Old versions of files, where available, are visible using the
<code>--b2-versions</code> flag. These can be deleted as required with
<code>delete</code>.</p>
<p>It is also possible to view a bucket as it was at a certain point in
time, using the <code>--b2-version-at</code> flag. This will show the
file versions as they were at that time, showing files that have been
deleted afterwards, and hiding files that were created since.</p>
<p>If you wish to remove all the old versions, and unfinished large file
uploads, then you can use the <code>rclone cleanup remote:bucket</code>
command which will delete all the old versions of files, leaving the
current ones intact. You can also supply a path and only old versions
under that path will be deleted, e.g.
<code>rclone cleanup remote:bucket/path/to/stuff</code>.</p>
<p>Note that <code>cleanup</code> will remove partially uploaded files
from the bucket if they are more than a day old. If you want more
control over the expiry date then run
<code>rclone backend cleanup b2:bucket -o max-age=1h</code> to remove
all unfinished large file uploads older than one hour, leaving old
versions intact.</p>
<p>If you wish to remove all the old versions, leaving current files and
unfinished large files intact, then you can use the <a
href="#cleanup-hidden"><code>rclone backend cleanup-hidden remote:bucket</code></a>
command. You can also supply a path and only old versions under that
path will be deleted, e.g.
<code>rclone backend cleanup-hidden remote:bucket/path/to/stuff</code>.</p>
<p>When you <code>purge</code> a bucket, the current and the old
versions will be deleted then the bucket will be deleted.</p>
<p>However <code>delete</code> will cause the current versions of the
files to become hidden old versions.</p>
<p>Here is a session showing the listing and retrieval of an old version
followed by a <code>cleanup</code> of the old versions.</p>
<p>Show current version and all the versions with
<code>--b2-versions</code> flag.</p>
<pre class="console"><code>$ rclone -q ls b2:cleanup-test

<h4 id="versions-naming-caveat-1">Versions naming caveat</h4>
<p>When using <code>--b2-versions</code> flag rclone is relying on the
file name to work out whether the objects are versions or not. Versions'
names are created by inserting timestamp between file name and its
extension.</p>
<pre class="console"><code>        9 file.txt
        8 file-v2023-07-17-161032-000.txt
       16 file-v2023-06-15-141003-000.txt</code></pre>
<p>If there are real files present with the same names as versions, then
behaviour of <code>--b2-versions</code> can be unpredictable.</p>
<h3 id="data-usage">Data usage</h3>
<p>It is useful to know how many requests are sent to the server in
different scenarios.</p>
<p>All copy commands send the following 4 requests:</p>
<pre class="text"><code>/b2api/v1/b2_authorize_account
/b2api/v1/b2_create_bucket
/b2api/v1/b2_list_buckets
/b2api/v1/b2_list_file_names</code></pre>
<p>The <code>b2_list_file_names</code> request will be sent once for
every 1k files in the remote path, providing the checksum and
modification time of the listed files. As of version 1.33 issue <a
href="https://github.com/rclone/rclone/issues/818">#818</a> causes extra
requests to be sent when using B2 with Crypt. When a copy operation does
not require any files to be uploaded, no more requests will be sent.</p>
<p>Uploading files that do not require chunking, will send 2 requests
per file upload:</p>
<pre class="text"><code>/b2api/v1/b2_get_upload_url
/b2api/v1/b2_upload_file/</code></pre>
<p>Uploading files requiring chunking, will send 2 requests (one each to
start and finish the upload) and another 2 requests for each chunk:</p>
<pre class="text"><code>/b2api/v1/b2_start_large_file
/b2api/v1/b2_get_upload_part_url
/b2api/v1/b2_upload_part/
/b2api/v1/b2_finish_large_file</code></pre>
<h4 id="versions-2">Versions</h4>
<p>Versions can be viewed with the <code>--b2-versions</code> flag. When
it is set rclone will show and act on older versions of files. For
example</p>
<p>Listing without <code>--b2-versions</code></p>
<pre class="console"><code>$ rclone -q ls b2:cleanup-test
        9 one.txt</code></pre>
<p>And with</p>
<pre class="console"><code>$ rclone -q --b2-versions ls b2:cleanup-test
        9 one.txt
        8 one-v2016-07-04-141032-000.txt
       16 one-v2016-07-04-141003-000.txt
       15 one-v2016-07-02-155621-000.txt</code></pre>
<p>Showing that the current version is unchanged but older versions can
be seen. These have the UTC date that they were uploaded to the server
to the nearest millisecond appended to them.</p>
<p>Note that when using <code>--b2-versions</code> no file write
operations are permitted, so you can't upload files or delete them.</p>
<h3 id="b2-and-rclone-link">B2 and rclone link</h3>
<p>Rclone supports generating file share links for private B2 buckets.
They can either be for a file for example:</p>
<pre class="console"><code>./rclone link B2:bucket/path/to/file.txt
https://f002.backblazeb2.com/file/bucket/path/to/file.txt?Authorization=xxxxxxxx
</code></pre>
<p>or if run on a directory you will get:</p>
<pre class="console"><code>./rclone link B2:bucket/path
https://f002.backblazeb2.com/file/bucket/path?Authorization=xxxxxxxx</code></pre>
<p>you can then use the authorization token (the part of the url from
the <code>?Authorization=</code> on) on any file path under that
directory. For example:</p>
<pre class="text"><code>https://f002.backblazeb2.com/file/bucket/path/to/file1?Authorization=xxxxxxxx
https://f002.backblazeb2.com/file/bucket/path/file2?Authorization=xxxxxxxx
https://f002.backblazeb2.com/file/bucket/path/folder/file3?Authorization=xxxxxxxx
</code></pre>

<p>Properties:</p>
<ul>
<li>Config: versions</li>
<li>Env Var: RCLONE_B2_VERSIONS</li>
<li>Type: bool</li>
<li>Default: false</li>
</ul>

<li>Type: Time</li>
<li>Default: off</li>
</ul>
<h4 id="b2-upload-cutoff">--b2-upload-cutoff</h4>
<p>Cutoff for switching to chunked upload.</p>
<p>Files above this size will be uploaded in chunks of
"--b2-chunk-size".</p>
<p>This value should be set no larger than 4.657 GiB (== 5 GB).</p>
<p>Properties:</p>
<ul>
<li>Config: upload_cutoff</li>
<li>Env Var: RCLONE_B2_UPLOAD_CUTOFF</li>
<li>Type: SizeSuffix</li>
<li>Default: 200Mi</li>
</ul>
<h4 id="b2-copy-cutoff">--b2-copy-cutoff</h4>
<p>Cutoff for switching to multipart copy.</p>
<p>Any files larger than this that need to be server-side copied will be
copied in chunks of this size.</p>
<p>The minimum is 0 and the maximum is 4.6 GiB.</p>
<p>Properties:</p>
<ul>
<li>Config: copy_cutoff</li>
<li>Env Var: RCLONE_B2_COPY_CUTOFF</li>
<li>Type: SizeSuffix</li>
<li>Default: 4Gi</li>
</ul>
<h4 id="b2-chunk-size">--b2-chunk-size</h4>
<p>Upload chunk size.</p>
<p>When uploading large files, chunk the file into this size.</p>
<p>Must fit in memory. These chunks are buffered in memory and there
might a maximum of "--transfers" chunks in progress at once.</p>
<p>5,000,000 Bytes is the minimum size.</p>
<p>Properties:</p>
<ul>

<li>Env Var: RCLONE_B2_UPLOAD_CONCURRENCY</li>
<li>Type: int</li>
<li>Default: 4</li>
</ul>
<h4 id="b2-disable-checksum">--b2-disable-checksum</h4>
<p>Disable checksums for large (&gt; upload cutoff) files.</p>
<p>Normally rclone will calculate the SHA1 checksum of the input before
uploading it so it can add it to metadata on the object. This is great
for data integrity checking but can cause long delays for large files to
start uploading.</p>
<p>Properties:</p>
<ul>
<li>Config: disable_checksum</li>
<li>Env Var: RCLONE_B2_DISABLE_CHECKSUM</li>
<li>Type: bool</li>
<li>Default: false</li>
</ul>
<h4 id="b2-download-url">--b2-download-url</h4>
<p>Custom endpoint for downloads.</p>
<p>This is usually set to a Cloudflare CDN URL as Backblaze offers free
egress for data downloaded through the Cloudflare network. Rclone works
with private buckets by sending an "Authorization" header. If the custom
endpoint rewrites the requests for authentication, e.g., in Cloudflare
Workers, this header needs to be handled properly. Leave blank if you
want to use the endpoint provided by Backblaze.</p>
<p>The URL provided here SHOULD have the protocol and SHOULD NOT have a
trailing slash or specify the /file/bucket subpath as rclone will
request files with "{download_url}/file/{bucket_name}/{path}".</p>
<p>Example: &gt; https://mysubdomain.mydomain.tld (No trailing "/",
"file" or "bucket")</p>
<p>Properties:</p>
<ul>
<li>Config: download_url</li>
<li>Env Var: RCLONE_B2_DOWNLOAD_URL</li>
<li>Type: string</li>
<li>Required: false</li>
</ul>
<h4 id="b2-download-auth-duration">--b2-download-auth-duration</h4>
<p>Time before the public link authorization token will expire in s or
suffix ms|s|m|h|d.</p>
<p>This is used in combination with "rclone link" for making files
accessible to the public and sets the duration before the download
authorization token will expire.</p>
<p>The minimum value is 1 second. The maximum value is one week.</p>
<p>Properties:</p>
<ul>
<li>Config: download_auth_duration</li>
<li>Env Var: RCLONE_B2_DOWNLOAD_AUTH_DURATION</li>
<li>Type: Duration</li>
<li>Default: 1w</li>
</ul>
<h4 id="b2-memory-pool-flush-time">--b2-memory-pool-flush-time</h4>
<p>How often internal memory buffer pools will be flushed. (no longer
used)</p>
<p>Properties:</p>
<ul>
<li>Config: memory_pool_flush_time</li>
<li>Env Var: RCLONE_B2_MEMORY_POOL_FLUSH_TIME</li>
<li>Type: Duration</li>
<li>Default: 1m0s</li>
</ul>
<h4 id="b2-memory-pool-use-mmap">--b2-memory-pool-use-mmap</h4>
<p>Whether to use mmap buffers in internal memory pool. (no longer
used)</p>
<p>Properties:</p>
<ul>
<li>Config: memory_pool_use_mmap</li>
<li>Env Var: RCLONE_B2_MEMORY_POOL_USE_MMAP</li>
<li>Type: bool</li>
<li>Default: false</li>
</ul>
<h4 id="b2-lifecycle">--b2-lifecycle</h4>
<p>Set the number of days deleted files should be kept when creating a
bucket.</p>
<p>On bucket creation, this parameter is used to create a lifecycle rule
for the entire bucket.</p>
<p>If lifecycle is 0 (the default) it does not create a lifecycle rule
so the default B2 behaviour applies. This is to create versions of files
on delete and overwrite and to keep them indefinitely.</p>
<p>If lifecycle is &gt;0 then it creates a single rule setting the
number of days before a file that is deleted or overwritten is deleted
permanently. This is known as daysFromHidingToDeleting in the b2
docs.</p>
<p>The minimum value for this parameter is 1 day.</p>
<p>You can also enable hard_delete in the config also which will mean
deletions won't cause versions but overwrites will still cause versions
to be made.</p>
<p>See: <a href="#lifecycle">rclone backend lifecycle</a> for setting
lifecycles after bucket creation.</p>

<p>To reset the current lifecycle rules:</p>
<pre class="console"><code>rclone backend lifecycle b2:bucket -o daysFromHidingToDeleting=30
rclone backend lifecycle b2:bucket -o daysFromUploadingToHiding=5 -o daysFromHidingToDeleting=1</code></pre>
<p>This will run and then print the new lifecycle rules as above.</p>
<p>Rclone only lets you set lifecycles for the whole bucket with the
fileNamePrefix = "".</p>
<p>You can't disable versioning with B2. The best you can do is to set
the daysFromHidingToDeleting to 1 day. You can enable hard_delete in the

<h2 id="limitations-8">Limitations</h2>
<p><code>rclone about</code> is not supported by the B2 backend.
Backends without this capability cannot determine free space for an
rclone mount or use policy <code>mfs</code> (most free space) as a
member of an rclone union remote.</p>
<p>See <a href="https://rclone.org/overview/#optional-features">List of

<p>Paths are specified as <code>remote:path</code></p>
<p>Paths may be as deep as required, e.g.

y/e/d&gt; y</code></pre>
<p>See the <a href="https://rclone.org/remote_setup/">remote setup
docs</a> for how to set it up on a machine without an internet-connected
web browser available.</p>
<p>Note that rclone runs a webserver on your local machine to collect
the token as returned from Box. This only runs from the moment it opens
your browser to the moment you get back the verification code. This is
on <code>http://127.0.0.1:53682/</code> and this may require you to
unblock it temporarily if you are running a host firewall.</p>
<p>Once configured you can then use <code>rclone</code> like this
(replace <code>remote</code> with the name you gave your remote):</p>
<p>List directories in top level of your Box</p>
<pre class="console"><code>rclone lsd remote:</code></pre>
<p>List all the files in your Box</p>
<pre class="console"><code>rclone ls remote:</code></pre>
<p>To copy a local directory to an Box directory called backup</p>
<pre class="console"><code>rclone copy /home/source remote:backup</code></pre>
<h3 id="using-rclone-with-an-enterprise-account-with-sso">Using rclone
with an Enterprise account with SSO</h3>
<p>If you have an "Enterprise" account type with Box with single sign on
(SSO), you need to create a password to use Box with rclone. This can be
done at your Enterprise Box account by going to Settings, "Account" Tab,
and then set the password in the "Authentication" field.</p>
<p>Once you have done this, you can setup your Enterprise Box account
using the same procedure detailed above in the, using the password you
have just set.</p>
<h3 id="invalid-refresh-token">Invalid refresh token</h3>
<p>According to the <a
href="https://developer.box.com/v2.0/docs/oauth-20#section-6-using-the-access-and-refresh-tokens">box
docs</a>:</p>
<blockquote>
<p>Each refresh_token is valid for one use in 60 days.</p>
</blockquote>
<p>This means that if you</p>
<ul>
<li>Don't use the box remote for 60 days</li>
<li>Copy the config file with a box refresh token in and use it in two
places</li>
<li>Get an error on a token refresh</li>
</ul>
<p>then rclone will return an error which includes the text
<code>Invalid refresh token</code>.</p>
<p>To fix this you will need to use oauth2 again to update the refresh
token. You can use the methods in <a
href="https://rclone.org/remote_setup/">the remote setup docs</a>,
bearing in mind that if you use the copy the config file method, you
should not use that remote on the computer you did the authentication
on.</p>
<p>Here is how to do it.</p>

<h3 id="modification-times-and-hashes-2">Modification times and
hashes</h3>
<p>Box allows modification times to be set on objects accurate to 1
second. These will be used to detect whether objects need syncing or
not.</p>
<p>Box supports SHA1 type hashes, so you can use the
<code>--checksum</code> flag.</p>
<h3 id="restricted-filename-characters-3">Restricted filename
characters</h3>
<p>In addition to the <a
href="https://rclone.org/overview/#restricted-characters">default
restricted characters set</a> the following characters are also
replaced:</p>
<table>
<thead>
<tr class="header">
<th>Character</th>
<th style="text-align: center;">Value</th>
<th style="text-align: center;">Replacement</th>
</tr>
</thead>
<tbody>
<tr class="odd">
<td>\</td>
<td style="text-align: center;">0x5C</td>
<td style="text-align: center;">＼</td>
</tr>
</tbody>
</table>
<p>File names can also not end with the following characters. These only
get replaced if they are the last character in the name:</p>
<table>
<thead>
<tr class="header">
<th>Character</th>
<th style="text-align: center;">Value</th>
<th style="text-align: center;">Replacement</th>
</tr>
</thead>
<tbody>
<tr class="odd">
<td>SP</td>
<td style="text-align: center;">0x20</td>
<td style="text-align: center;">␠</td>
</tr>
</tbody>
</table>
<p>Invalid UTF-8 bytes will also be <a
href="https://rclone.org/overview/#invalid-utf8">replaced</a>, as they
can't be used in JSON strings.</p>
<h3 id="transfers-1">Transfers</h3>
<p>For files above 50 MiB rclone will use a chunked transfer. Rclone
will upload up to <code>--transfers</code> chunks at the same time
(shared among all the multipart uploads). Chunks are buffered in memory
and are normally 8 MiB so increasing <code>--transfers</code> will
increase memory use.</p>
<h3 id="deleting-files">Deleting files</h3>
<p>Depending on the enterprise settings for your user, the item will
either be actually deleted from Box or moved to the trash.</p>
<p>Emptying the trash is supported via the rclone however cleanup
command however this deletes every trashed file and folder individually
so it may take a very long time. Emptying the trash via the WebUI does
not have this limitation so it is advised to empty the trash via the
WebUI.</p>
<h3 id="root-folder-id">Root folder ID</h3>
<p>You can set the <code>root_folder_id</code> for rclone. This is the
directory (identified by its <code>Folder ID</code>) that rclone
considers to be the root of your Box drive.</p>
<p>Normally you will leave this blank and rclone will determine the
correct root to use itself.</p>
<p>However you can set this to restrict rclone to a specific folder
hierarchy.</p>
<p>In order to do this you will have to find the <code>Folder ID</code>
of the directory you wish rclone to display. This will be the last
segment of the URL when you open the relevant folder in the Box web
interface.</p>
<p>So if the folder you want rclone to use has a URL which looks like
<code>https://app.box.com/folder/11xxxxxxxxx8</code> in the browser,
then you use <code>11xxxxxxxxx8</code> as the
<code>root_folder_id</code> in the config.</p>
