The lists do not show on the web interface of the backup server because
VIRTUAL_HOST_OVERVIEW is On (the default) and the host name of the
backup server is different from the primary server. If you set


in mm_cfg.py, you'll see the lists on the backup, but if it is ever
necessary to switch to the backup, presumably you'll do that by
changing the primary name's IPs in DNS to point to the backup, in
which case you'll be accessing the backup via the primary names and
you'll see the lists anyway.

What about archives? Why not just rsync all of /var/lib/mailman?
