# This script mounts Windows share.
# Этот скрипт маунтит разшаренную папку у Windows.
# В конфигах fsbackup должны быть параметры:
#  $cfg_type = "local";
#  $cfg_local_path = "/usr/local/fsbackup/archive";
#
# Нужна установленная Samba с поддержкой CIFS и netcat. Require:
#   * for gentoo: USE="ads client smbclient" emerge -v net-fs/samba net-analyzer/netcat
#   * for Debian-10: apt install cifs-utils smbclient netcat-traditional
#
