You can have rsync do hardlinks for unchanged files on the remote side,
but this relies on having a directory structure on the remote side that
has one directory for each day, or having a script on the remote side
which moves directories around. (This could be done by an SSH call
before the rsync).

For GUI, the is a KDE utility called Keep that works well, I think
(never used it).

For more complex, I highly recommend Bacula. I've done four bacula
deployments (from a two computer office to a 20 computer + 10 server
office) and it works well and is dead reliable. It takes some doing to
get set up, but once set up, it is truly "fire and forget." Unless of
course, you need to swap out tapes.
