Also, make sure on the properties of the master, the Max jobs Per Client is
set to a high number (I usually set to 99)

Make sure your storage unit definitions allow multiple jobs per drive.

Be sure your policy allows multiple jobs (allow multiple data streams) and
"limit jobs per policy" to more than one.

Even then, you'll only share tapes if it's the same retention period and
tape pool.

Dear All,

My apologies for a dummy question...

VERITAS NetBackup(tm) DataCenter 3.4 System Administrator's Guide
http://dlc.sun.com/pdf/875-1921-10/875-1921-10.pdf  describes how to setup
"Maximum multiplexing per drive" (see "Managing Storage Units" and then
select "Storage Unit Type Properties - Media Manager Storage Units"  pages
30-31).

I have set "Maximum multiplexing per drive" to 2, I see jobs queued in the
"Activity monitor", but I have never seen more than one backup active.

What am I missing?

Thank you,
Aleksandr
