Look in NetBackup Admin Guide II in the chapter called 'Additional
configuration' -> Multiplexing.

It describes in detail how multiplexing works, how multiple backups are
written to one drive and when a 2nd drive will be used.

Subject: [Veritas-bu] How to backup to multiple drives


I have a two drive library (msl 5000) with two LTO2 drives. When I
backup large data I would like it to split the data up and backup using
both drives. Is this a possibility?  I've been googling and found
multiplexing and I think I have enabled multiplexing or the storage unit
and set Max concurent write drives to 2 and checked the enable
multiplexing box and set maximum streams per drive to 2. But my backup (
sent via command line) is still only using one drive. 

Is there a point where NBU makes a decision on when to utilize the
second drive?
