You might also want to look at rdiff-backup. It uses librsync to do its backups. Looks to be pretty good.

lan, i wouldn't bother with tar/incremental backups unless space on the
backup server is really tight. using the rsync method that jeremy linked
to earlier is probably the best bet, or just copy the files directly if
you're really lazy like me. make a seperate directory for each day of
the week and use a cron job to copy data to the appropriate directory on
the appropriate day. that way if you need to restore a file from three
days ago you can do it in about three seconds. if you have the space for
it save the friday directories and rotate them so you always have three
or four, that way you can go back a month or so if necessary.
mentioned (based on the rsync article) does this exact thing -- takes
snapshots for each day, allowing you to access previous versions. The
nice thing is that it uses hard links for files that haven't changed, so
a lot of space is saved. And since rsync is used, files that haven't
changed aren't copied, saving time and network bandwidth. It's really
very easy to set up. I'm testing this on the TriLUG backup server now.
For even more space savings, look into "rdiff-backup" which only storesI'm usually hyperventilating by the time I realize I need a backup. I think I'll pay the cost of increased storage room.. The rsync feature of copying only what's changed should work out very well.
deltas (differences) between files, but it does require a special
utility to recover the files.
