If a client is backing up files to a primary storage pool while
that pool is being backed up to a copy storage pool, the following
behavior can be expected
o Any files stored in the primary pool before the storage pool backup
  begins will be copied to the copy pool
o Any files that do not get stored in the primary pool until after
  the storage pool backup ends, will not be copied to the copy pool
o Files that get stored in the primary pool while the storage pool
  backup is in progress may possibly be copied to the copy pool
  (it all depends on the timing between the client backup and
  storage pool backup operations).

I'm trying to determine what will happen in the following situation:
I'm trying to determine what will happen in the following situation:
*STG pool(on DASD) is being "backed-up" to a copy pool (cart) for disaster
recovery vaulting
        1)clients backup had been running during this but finishs before 
copypool
offload is complete
        2)a new client backup starts but doesn't complete before offload does
        3)a new client backup starts and ends before offload finishes.

What will happen to those files in regards to the copypool offload in the
above scenerios??  Thanks.
