Yes, This would back up everything you would need to restore the list
and its archives. It ignores the problem of partially processed
messages still in a queue, but this is not usually of much concern,
especially if you're shutting down the list.

One thing to add - to restore, you don't need to first create the list.
Just stop Mailman, untar and start Mailman. If you are really careful,
you could also shut down web access during the restore. This and the
stop/start are not mandatory, but temporary errors could occur if
messages or web activity came against the restored list when it was in
a partly restored state.
