It might also be interesting to try the subversion version control
system for something like this since it has a binary difference
mechanism built in. You'd have to do some extra planning to use it for
backups though, because it wants to keep an extra copy of the previous
repository version locally (so it can compute the diffs to commit) and
there is no easy way to ever remove anything from the repository. You'd
probably want to create new repositories on some schedule so you could
delete the old ones completely.
