After this run, two new tape file entries have a new physical copy number from
the parallel BACKCOPY run:
The four volume sets contain the same data and are interchangeable with each
other. For individual tape substitution, only the tapes within the same physical
copy number can be switched. In other words, tape X00019 could be
substituted for X00016, or X00034 for X00031, but X00034 could not be
substituted for X00019.
2. Make two more copies of PAYROLL_BACKUP, but this time run BACKCOPY
twice to produce a new physical copy number copy from each run:
