If you have database dumps or big text files that aren't compressed,
backuppc could be a big win.  I think it is the only thing that can
keep a compressed copy on the server side and work directly with a
stock rsync and uncompressed files on the target hosts (and it can
cache the block-checksums so it doesn't have to uncompress and
recompute them every run).   While it is 'just a perl script' it's not
quite what you expect from simple scripting...
