If you use:

  UserKnownHostsFile    /dev/null
  StrictHostKeyChecking no

in the backuppc user's ~/.ssh/config or some other equivalent, you can bypass that manual check.

Of course it disables some security features, but for my purposes this is acceptable.

I'm setting up some Raspberry Pis and I set up BackupPC to back them up using ssh+rsync. I installed the key in ~backuppc/.ssh/authorized_keys but the initial backup was still failing. So I tried manually ssh'ing into the Pi and discovered I was hitting the question to add the Pi to known_hosts. I don't see this mentioned in the documentation. I'm not sure where it would even go, but I wanted to mention it as I'll likely forget this a year from now.
