rdiff-backup is an absolutely brilliant backup-to-remote-system
application.  We use it for backing up all our local disks to one
central system, and that system is then backed up to tape.  Saves a lot
on Veritas Netbackup licenses.

rdiff-backup only does incremental backups, so the only thing you're
backing up are the diffs from the previous backup.  As a result, you can
restore any file to any backup just by entering the date/time you want. 
Backups are (can be) compressed, so day-to-day backups are minor.  You
can also expire old backups.
