[Veritas-bu] NetBackup tape usage

Hi,

I'm running NetBackup with a tape jukebox.  When I look at the media
list I see the following:


 id     rl  images   allocated      last updated     den     kbytes  restores
           vimages   expiration     last read        <------- STATUS ------->

My question is about the "FULL" tapes.  The amount of data on each
tape varies quite a bit, from 89+ GB down to less than 36GB.  Why the
huge disparity?
