You can prove it to yourself: set up a new disk stgpool, and a new tape pool; use one disk vol. incr a small filesystem there, and back up the disk pool. q cont [diskvol name] copied=no (should be "no data") Touch a file on the filespace, re-incr. q cont [diskvol name] copied=no (your file should show up.) migrate the data to your tape stg. q cont [tapevol name] copied=no (the changed file, and only it, should show up.) If you get a different response, let us know. ;) - Allen S. Rout
