Good, a backup of this client should work just fine.

Problem: you must add the SSH key of the backuppc user
(/var/lib/backuppc/.ssh/id_dsa.pub or id_rsa.pub in the BackupPC
server) to the authorized keys file of the root user
(/root/.ssh/authorized_keys or the deprecated authorized_keys2) on
client2.

If it worked with "sudo -u backuppc" then it is wrong in that client1
should not have a "backuppc" user. Remove it.

Good, that is what is expected.

Wrong. Remove it.
