Salem,

Management want 28 copies or a file version anywhere in 28 days? If you set
up 28 versions and retention to 28 days. You will able to give 'em any file
version in 28 days. There is no primary pool. You might be meaning primary
disk pool. Files move in daily migration from primary disk pool to primary
tape pool. If you have already set-up migration process then your daily
backup should be migrated to tape pool. If management want disaster recovery
solution ( in case of fire, earth-quake) you need to copy primary tape pool
to copy pools. I hope this will clear-up some concepts.
