Peter,
Your script looks like it might do the trick for me. I do have a couple
of questions though. How would I adapt it for a remote backup location?
/mnt/backup is a normally unmounted disk on my secondary Gentoo box. I
have configured passwordless ssh between USER with sudo privledges on
the machine to be backed up, to [EMAIL PROTECTED] The way to ssh in to
the remote box, mount /mnt/backup and then do the rsync eludes me. I
wonder if you might steer me in the right direction.
The second question is about the rsync command in your script. What
does the --delete option do? Does it delete old backups? Forgive me for
being a bit dense here, but I'm rather new at scripting.
