Did you ssh-copy the keys in question from the BPC-server to the host to be 
backed up?

I usually get that message when BPC can't connect to the backupee.

>>From our internal FAQ:
Q: How do I setup the RSA-key for passwordless rsync for BackupPC (BPC) clients?
 
A: On mach012 or mach021, depending on if it's for instrument backup (m12) or 
user backup (m21):

bash-3.2$ su -s /bin/bash - backuppc
bash-3.2$ cd /bak
bash-3.2$ ssh-copy-id -i .ssh/id_dsa.pub root AT machine.tobe.backedup DOT com
