After the separate BACKCOPY runs, two more tape file entries are in the file
catalog. Each separate run has a different physical copy number:
You now have four physical copies of PAYROLL_BACKUP cataloged for
generation 1. Two of the physical copies comprise two sets of logical copies.
All six volume sets can be substituted on a set-for-set basis. Only the volume
sets within the logical volume sets of physical set 1 can be substituted tape-for-
tape, and only the volume sets within physical set 2 can be substituted tape-
for-tape.
