Ssh works as a pipe - anything written to stdout on the remote side can 
be read through ssh just like a local pipe.  The default tar and rsync 
commands configured in backuppc use this feature correctly.  They should 
be listed in the documentation at 
http://backuppc.sourceforge.net/faq/BackupPC.html#configuration_file in 
case you've forgotten what you changed.

Ubuntu has a root account (as anything resembling unix must).  It just 
doesn't have a password assigned by default - and you don't need one for 
key-pair based ssh access.
