Have you tried backuppc?  There are some tradeoffs because it makes an
extra hardlink into a pool directory tree where the name is a hash of
the content, but it takes care of all the other stuff for you and
would let you store a much longer history, especially if there are
duplicate copies of any of the files spread around.
