zfs really shines here.  Only the filename change would be transmitted.

And if you're using opensolaris you can add in AVS to get real time
continous synchronous replication if you want.  (I would also consider
having the MTA duplicate the mail to a 2nd mail server and use another
method to synchronize deletions and flag changes.)
