Yes, this should work fine (as long as the machine name doesn't change).

Of course, it has the drawback that you have to stop rabbitmq-server.

An interesting question is whether the above backup procedure will work
without stopping rabbitmq-server.  It would probably seem to work, but
whether it works under all circumstances is uncertain.  Though it would
certainly work if you use a filesystem that can give you point-in-time
snapshots.
