I am using BackupPC 4.3.1-3 from the yum repository for CentOS 7. Very good to hear that you got it working on your installation. I am positive that SSH authentication is set up correctly. The problem doesn't seem to be authentication. There isn't even an authentication attempt being logged on either server. It's even worse, tcpdump does not even report outgoing packets to port 22. Weirdly, when the SSH commands are run manually, the outgoing packets are visible, and the whole SSH connection is being set up successfully. I am just speculating here, but could it be that when the BackupPC software is handling the SSH process, it is somehow unable to deal with the implictly added ProxyCommand arguments? Also, not trying to be cheeky here: for added security you don't actually need AgentForwarding nor root logins when using a jump host.
