This is not a matter of multiple jobs per policy.
To get more than one job to the tape, you have to set the schedule to use
multiplexing.
You do only share tapes at the same retention levels, but you can get
multiple jobs to the same tape drive.
Be careful. You can over do multiplexing very easy.

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
