That may be your configuration; it is not the default in Ubuntu or in
OpenSSH upstream.  Anyway, you might consider backing off from
"PermitRootLogin no" to "PermitRootLogin forced-commands-only" (which I
may well make the default at some point, though I'd prefer somebody to
make the case to upstream first).  At that point you can install an
uncompressed copy of /usr/share/doc/rsync/scripts/rrsync.gz somewhere
useful and make it the forced command for the SSH key used by your
backup system.  This works well.
