I had to do this a while back and, like you, found that rsync didn't
seem to work well. I ended up using a tarpipe instead, and that worked
great. I can't find my notes for the exact chant I used for it, but this
should be a good start:

I don't remember if I had to do this on our "little" BackupPC server or
on the big one, so I can't say what it's performance was like. I just
remember that it worked, and rsync did not.
