You do have to answer 'yes' to the prompt from ssh the first time it 
connects to a new target even if you already have the keys in place. 
Most people probably use ssh or scp to transfer the keys, using the 
password for the first connection - or at least to a manual ssh 
connection as a test and thus avoid this issue.  This results in an 
entry for each target in /home/backuppc/.ssh/known_hosts - which has to 
be removed if the host key at the target ever changes (OS reinstall, etc.).
