Everytime the backup of the tape storage pool runs it says there is no data to backup. I run a

Q CONTENT VOLNAME COPIED=NO

and it comes up with no results, so everything on the tape pool volume has been backed up.


I'm confused whether or not the diskpool and the primary tape pool have the exact same data and that's no data is backed up from the tapepool. A migration runs every day from the diskpool to the tape pool, and right now the high migration percentage on the diskpool is lower than the percentage utilized. So on the one hand both pools sound like they have the same data and on the other hand they don't.

Any ideas how to find the right answer?
