or, more clearly, no, it is completely impossible. It's *exactly* the same as asking "isn't it possible that if I try to login as the backuppc user, the computer will print out the password I need to complete the procedure?". You see, that is the benefit of actually *understanding* what is happening. You appreciate what of what you did was nonsense and what was necessary. You should never give instructions without that understanding, because you will be doing harm. It seems I need to repeat what I've already pointed out one last time. Without a (passwordless) private key in backuppc_server:~backuppc/.ssh/id* and the corresponding public key in backuppc_client:~whoever/.ssh/authorized_keys* automatic backups with transfer <something> over "ssh -l whoever" *won't work*. Period. Additionally putting other keypairs elsewhere won't impair that but *will compromise security*. End of transmission.
