Hmm, I think something like the ssh-then-su method still could work,
but you would need some more complicated wrapper...  Ok, how about
these suggestions instead:

1.  Suid script that runs rdiff-backup --server.  I think you would
    have to create another user id, and make sure only that user has
    access to the script.

2.  Instead of running rdiff-backup on machine A and trying to get it
    to log in to machine B which doesn't accept ssh root logins, run
    rdiff-backup on machine B (after you 'su' normally) with machine A
    being remote.

3.  Reconfigure ssh on the remote machine to accept root logins.  To
    do this, make sure the line

PermitRootLogin yes

    appears in your sshd configuration file, usually at
    /etc/ssh/sshd_config.

Anything here look promising?
