This looks good.

Do you get any of this output in a non-interactive session?  Try something like:
ssh -l root dhcp id
and see if you get more than the one line response.   The backuppc
implementation of rsync won't work if there is any other output before
the remote rsync starts. Otherwise, as long as /usr/bin/rsync exists
on the remote side it looks like it should work.
