You're right - user-defined backups won't break into multiple streams.
You can do multiple bpbackup commands.  If you do them in rapid
succession, NetBackup will usually multiplex them correctly onto a tape.
Something like:

for dir in Microsoft Information Store:\*SG*
do
  bpbackup -p policy_name -s ubak_schedname -t 16 $dir
done

Of, if there's sufficient permissions, you can build a policy & then
call the scheduler to perform the backup.  The scheduler can do the
multi-stream inherently.

Policy has 
INCLUDE: Microsoft Information Store:\*SG*
"Allow Multiple Streams": Checked

Build it with a "full" policy but no schedule defined.

Then call the scheduler:
bpbackup -i -p <policy> -s <sched> -h <host>

-M

Subject: [Veritas-bu] multistream a user-defined backup.

I am trying to back up some Exchange datastores using a user-defined
backup (we do not want the logs truncated, our storage system takes care
of that).  I would like to backup all of the stores at once, but I can't
get to work.  Backing up using a full schedule with mulitstreaming backs
up each store in its own stream, but user-defined does not.  Can anyone
assist me with this? The bpbackup command I am using on the client looks
like this:

bpbackup -p policy_name -t 16 "Microsoft Information Store:\*SG*"

Thanks.
