There is good advice in the manuals, however to understand it a little
better............
 
Within your storage unit, you probably have multiple drives defined. In this
example, lets say you have 2 Tape Drives. In the properties of the Storage
unit, you can configure how many jobs are multiplexed onto the drive. this
will tell NBU it can multiplex onto any single "drive" within your storage
unit configured".
 
I think the Max you can have is 32. NBU sends multiplex backups from one or
many clients to a single drive and this is then backed up to media.
 
Within your POLICY, in the Schedule, you can configure how many streams you
want multiplex into a drive as well :-)
 
So, lets assume you have a Policy with 8 streams and you want to use TWO
Drives.... configure the schedule to Multiplex 4 streams onto 1 drive - thus
4 streams written to drive 1 and 4 to drive 2. (assuming the drives are free
otherwise they queue).
 
That is my basic understanding of it!
 
Does this help?

Subject: [Veritas-bu] multiplexing



Can someone explain what this does? How can I backup data and have it
stripped across more drives to speed a back up faster? We are having a
"discussion" about this and how multiplexing works versus data streaming.

Thanks
