With such a small number of users, you might be all set.  Keep in  
mind that -u only gets users, not shared mailboxes not associated  
with any user.  In UMich's system, we just run tape backups on the  
replica, no need for a second replica.  I've done cost comparisons  
between having two replicas or having the first replica write to tape  
(answer: depends).
