Better yet is rdiff-backup: http://rdiff-backup.stanford.edu/

It uses the base rsync algorithm, but stores changes from one day to the
next in binary deltas (computed with that rsync algorithm), so you can have
incremental backups that actually end up using less space than incrementals
in traditional systems would -- since it doesn't even store whole files than
changed, just what changed in them.
