We are using BRMS and the auto virtual tape image catalog system.
   We set the image catalog size in BRMS at 43GB.
   BRMS then dynamically creates image catalogs as necessary during the
   backup.
   Currently it takes 8 volumes to back up our system.  A smaller allocation
   size conserves space on our disk.
   We move the image catalog files off to BLOB space with sFTP directly after
   the BRMS backup and then delete the image catalogs in prep for the next
   night.
   This simple system is working for us.

 I suspect it was retaining all the stuff that the help mentions in allocated size of the object.
 Big difference between virtual tape and a virtual tape library is that the full 500GB space is not tied up in a virtual tape library for a 500GB tape.  Dedup and allocation is more dynamic and way smaller.
 But thanks.  I did clear up some space for some virtual tape stuff used for installing some vendor stuff.
