Make sure you are running the command:

ssh -l backuppc xxx.xxx.xxx.xxx whoami

FROM the backuppc server AND AS the backuppc user, AND xxx.xxx.xxx.xxx
is the exact same hostname that backuppc will use when attempting to run
the backup. You should see the command line backuppc runs in the failed
logs, you can get the hostname from there.

You may simply need to add the host key for backuppc, which you will be
able to do from the above.

Adam
