We're using rsync 2.4.1 for hourly syncs between computers over ssh and
it works great.

You can control the mode with '--delete'. The default is to just "add" not
delete.  I'm actually not sure what you want here. 

I'm not saying rsync is the right answer for backups, but it is sure handy
for mirroring.
