[Dovecot] Using namespaces to duplicate mailboxes (Doable?)

Greetings.

As part of a new installation of dovecot, we are exploring backup
options, and wondered if it's at all possible to define a couple of
namespaces where messages get duplicated to be saved in another disk for
fast recovery. (we do not intent to load balance between the two, all we
would like is to see if it's possible to have duplicate mailboxes so to
keep a fast working backup _besides_ normal methods: tape, external
disk, etc.)

The whole idea behind this would be that in case of a major failure of
the array holding the mailboxes, a fast working backup can be put in
place. Other thing we would like to know (and i reckon it's a long shot)
 if it's possible to "hide" this mailbox copy from the IMAP clients, so
as to prevent any user from subscribing _again_ to the same folders.
Naturally this last thing is to be considered only if the former
(mailbox copy trough namespaces or other dovecot _internal_ method) it's
at all possible.

Any feedback or better ideas are totally welcome.
