I just posted something similar, but take a look at this link..

I personally do not see the need for BLB (brick level backups) of Mailboxes.
The performance you get for the IS is very good - BLB does not surprise me
too much and I am not a fan of BLB at all.

Subject: [Veritas-bu] Exchange 2003 Mailbox Backups



We've just upgraded our Exchange server and one of the improvements was to
split the information store into 3 storage groups (only 2 contain data that
needs to be backed up though).  Each storage group has 2 stores.  Does
anyone have any suggestions on how I can use this to improve my mailbox
backup performance?  An Information store backup of about 95GB takes about
45 minutes.  The mailbox backups take about 20-30 hours.  Because of that I
only do a mailbox backup once a month.  I was thinking about trying
concurrent backups ... but the Exchange administrator does not think we'll
get any better throughput but what if I backup up one store every weekend?
How would I address that store in the policy?  I use 5.1 MP4 and currently
the Mailbox backup policy Directive set is set to MS_Exchange_2000 and the
Pathname or directive is Microsoft Exchange Mailboxes:\.  

 

Thanks,

Mike Day
