Duplicate a Tape Using a Single Tape Device. The tape is read in by the
DUPTAPIN command and written to a data base file. The DUPTAPOUT command can
then be used to create a duplicate to the same device. Multi-volume tapes are
supported. A significant amount of storage is needed to hold a tape. For
example, the system distribution tape will require approximately 500 MB of DASD
storage for V2R3.
