As Donovan Baarda already mentioned, you should probably use rdiff.
If you need to do the same thing with multiple files and want to keep
track of permissions, new/deleted files, etc., you may want to check
out rdiffdir, which is included in the duplicity package.  It combines
multiple rdiff signatures or deltas in tar format files.  See

for more information or to download.
