backuppc needs the private id_rsa file in it's .ssh directory. You need
to add the id_rsa.pub to tim's .ssh/authorized_keys file on helen...

Try making sure you can login as the backuppc user and do "ssh -l tim
helen id" and get just the string "tim" back.... You need to do that
once manually anyway to accept the SSH host key for backuppc user.
