They are in different pools with different retention periods, and no I do
not have multiple retention periods on same media enabled.

Since vault is just using bpduplicate, it's possible to end up with regular
& duplicated images on the same tape.

Use different volume pool for your duplicated images.  This'll ensure
separation.

I'm in the same boat you are with this Ed, I've even been seeing vaulted
images being listed with regular images on the same tape. I totally do not
understand how that has happened.

I thought I had a clue but 5.0 is throwing me for a loop.  A recent
vault run listed the images on a single tape that really stunned me.  It
was a mix of images from different volume pools from different media
servers, and some of the images should have already expired.  How it
came up with that beats me...
