    OK, that makes sense. But the rsync can occur using *neither* ssh nor rsh,
    simply using an rsync server on your backup system allowing write access, or
    an rsync server on your system being backed up and allowing a pull
    operation. Using the native rsync port and protocal, rather than tunneling
    it over rsh or ssh, prevents all sorts of potential user login issues.
