[lug] Tape backup error

[Hugh Brown]

from linux.local you could run this:

/usr/bin/ssh  backuphost 'tar cf - /etc'|(cd /backups/;tar xf -)


it would back up /etc on the machine backuphost into /backups on
linux.local

There's also the free backup system named amanda.  I've never used it,
but it might be worth looking into.
