That's alot of volume pools and policies for that number of clients.
It's also quite a few media servers for that size of robot.

What makes the different volume pools unique? In my environment, I
have 4 - Netbackup(catalog backups only in this one), onsite (tapes
that are kept onsite), offsite (copies of data that are shipped
offsite), and offsite_catalog (catalog backups that go offsite). The
only way I can see having many more than that is if you have multiple
types of media - but 34 is a bit on the extreme side. It might be
worth it to you to reduce down to a few with a clear designation on
why a piece of media would come from one rather than another.

Same goes for the number of policies - you have more policies than
clients, unless every client is running a database that needs special
attention - and unique special attention at that - 414 policies would
get difficult to manage.

The first place where you'll get gains is reducing the number of
volume pools. Take a closer look at WHY each of those pools exist.
Also - unless most of those media servers are SAN Media servers that
only back themselves up, try reducing the number of media servers that
you have. Maybe start with #of drives/2.

Remember, when a tape gets used by a media server - only jobs going
through that media server will go to that tape. When a tape is in a
volume pool, only jobs that use that volume pool can go to that tape.
If only 50G go through a media server in a night, and you've got that
split onto 3 or 4 volume pools, I'm not surprised at the low amounts
of data you're showing per tape.
