Exchange 2003, incremental mailbox backups?

[libove]

NW 6.2, Exchange Module 4.0, Exchange Server 2003.

From reading the manuals for the Exchange Module, it looks like there is no such thing as an incremental backup of the items within a single mailbox. This results in my 600MB mailbox being backed up EVERY night. That adds up to a lot of unnecessarily used tape footage. Yes, I know, use PSTs, but I LIKE accessing all of my archived mail from within OWA!

Is there a way, without moving data out of the mailbox in to PSTs, to get NetWorker and the Exchange module to do an actual incremental backup of the items in a mailbox, so that I can back up only each day's 10MB of spam, instead of the whole 600MB mailbox every night? :-/

Thanks.

I don't now if it helps, but this is possible with Exchange Module3.0 :
savegrp -G ExchangeGroup -l incr
where the group has the exchange client with MSEXCH:MB
We have: full=28 G, Incr=1,5Go

We will upgrade next month form Exchange2K to Exchange2003, and I will test this...

Unfortunately, Exchange module 3.0 does not support Exchange 2003.

A client configured:

MSEXCH:
MSEXCH:MB

.. produces this output (=====emphasis===== mine):

Note that the ~700MB and ~180MB sizes of the two private mailboxes is the entire size of those mailboxes, there's nothing incremental about it.

Thanks.

You are true; if you look to the "Module Exchange 4.0 Administrator's guide" (p 55-56), the Mailboxes and Public folders incremental backup are converted to full...
