Jim,
 
I think you're getting confused with Backup Exec licensing where more
than 1 tape drive per media server requires an additional license. 
 
NBU Enterprise/Data Centre (which is ALL I've ever seen running across
100s of sites in Europe) allows you to use as many standalone tape
drives as you wish. For library based tape drives you need one Library
Based Tape Drive license PER TAPE DRIVE. If you are sharing tape drives
you need one SSO license PER "physical" TAPE DRIVE.
 
You are correct that backups to DSU are included in the base license.
 
Backups to disk are MORE FLEXIBLE than to tape, hence better for slow
clients, but very few disk arrays/VTLs will match the speed of more than
a handful of LTO3 drives running well into their ATS/streaming speed
range (given clients and infrastructure that can deliver continuous data
at the required rates).
 
Hope that helps.

One standalone tape license comes with the mediaserver.
A standalone tape license is the same license as for a Tape
Library."Library Based Tape License"
You can run your backups to disk for free.
I can argue that disk is better than tape.(though not cheaper yet)
 
There are a lot of misconfigured configurations do to reseller
ignorance(In the past licensing was not strictly enforced)
Also Symantec/Veritas has not always configured a system correctly.
 
If you run without a correct license it will catch up with you or your
organization.(hopefully you have retired)
 
Jim

        Is it just a licnesing thing or does it add any actual value to
NBU?

        Tim, 
        
        The License Key "Library Based Tape License" may not be needed
to run NetBackup, but it is a legal requirement to be properly licensed
for it if you use a tape library of any kind.  There may be a different
license for stand alone tape drives, I am not sure about this.  It is my
understanding that you need 1 license for every tape drive you want to
use.
