Assuming the retention level is same for all three jobs NetBackup will
multiplex all three jobs to one single tape.

Subject: [Veritas-bu] Multiplexing Query


Hi all,

Would like to find out somemore info abt multiplexing using netbackup.

Example.
If i have 3 clients and 3 policies for each client using same storageunit
and same volume pool.
My storageunit have 3 drives and i set it to 3 concurrent drive write.
The policies of the 3 client i set multiplexing to 3.

Question
If i trigger all 3 policy all at the same time. Does netbackup do 1 or 2
assuming there are no other backup running from other media servers?

1. One drive will consolidate all 3 jobs to a single tape media?

2. One drive will be use for each job triggered, meaning the media server
will use up all three drives with 3 tape media?

Anyone have any idea?
