Hi,

I also run Ubuntu and BackupPC.  When I was reworking my system, Luis
Paulo opened my eyes concerning keys.  I now run using the visudo
technique to avoid backuppc having root privilege.  Read this articale:

http://backuppc.sourceforge.net/faq/ssh.html

Pay special attention to the visudo method.  I've been running it this
way for about a year now with no problems.  -- ken
