# not used by default unless the proper line is uncommented in backup-specs.
# System administrators will probably want to customize this and
# backup-specs for their site. 
#
# This script should be run by tar with --info-script (-F) to inform
# interested parties that a tape for the next volume of the backup needs to
# be put in the tape drive.

# Include location of `sendmail' and GNU finger.

# of changing tapes).

# Certain users (like `root') aren't real users, and shouldn't be notified.
# Neither should `zippy', `elvis', etc. (on the GNU machines) since they're
# just test accounts.

This is an automated report from the backup script running on 
`hostname`. 

Volume ${volno} of the backup needs to be put in the tape drive.  Usually
whoever prepared the backup leaves labeled tapes on top of the drive
itself.  If there aren't any more, information about where to find tapes
and how to label them are posted on the wall by apple-gunkies (unhelpfully
obscured by a bookshelf).  An online copy (which is probably more
up-to-date) can also be found in ~friedman/etc/fsf/backup.how.

This is an automated report from the backup script running on 
`hostname`. 

The backup has been continued, so for now no further attention is required.
