There is no method of creating parallel backup streams in the TDP for
Exchange product (unlike it's SQL counterpart).  The only way to
accomplish something similar is to break your backup script into
multiple jobs, each backing up a specific storage group.  Of course,
that also requires multiple node names, schedulers, etc.

Subject: [ADSM-L] Multiple Backup Streams with exchange.

I continue to find new corners of this product to explore - or maybe its
grope blindly in the dark !

I have a customer with an exchange cluster TDP 5.3.3.1 backing up to a
Win
2k3 server running tsm 5.3.4.  Storage agents are installed on both
sides
of the cluster at 5.3.4.

Exchange backups work fine, but the mail store has grown and they are
spilling into the online day - there are 4 drives available, but backups
only use one. Maxnummp for the node is set to 4.

I've been through the TDP for Exchange and Storage Agent manuals and can
see nothing that addresses a number of parallel streams.  I've tried
searching but obviously haven't come up with the right set of keywords.

Can someone point me in the right direction?

Thanks

Steve
