1. sshd_config only determines what the server side will allow. If the
client doesn't request X11Forwarding, the server won't somehow force it
upon the client.
2. In your case, the only sshd_config of interest would reside on the host
you are trying to back up (192.168.7.254, just to be over-clear).
3. Before you now go changing /etc/ssh/ssh_config on the BackupPC server,
you'd want to do that in the user configuration file ~backuppc/.ssh/config,
but,
4. that's not your problem.

^^
That should turn off X11 forwarding (not globally, not as default for the
user, but rather on a per-connection basis). That's perfectly fine as it is.

That means the message comes from the remote side. It appears the login
process (i.e. probably shell startup) is executing an X11 application with
$DISPLAY incorrectly set to :0.0 (it should be unset, and the startup
scripts shouldn't do it in the first place, really).
So:
- what is root's login shell on 192.168.7.254 (probably a bash, but you
never know ...)?
- what's in the relevant startup files (~root/.bashrc, ~root/.profile,
/etc/bash.bashrc, /etc/profile if I'm not mistaken). In particular, did
you modify any of them? Double check what you changed and remove the
part that's causing the problem ;-).
- For completeness' sake: which version of what distribution is running
on the client host?
Hope that helps.
Regards,
Holger
P.S.: If you had wanted to read the second part of my reply first, you
should have quoted the response before your reply and not after.
