GDS management class

Data sets in generation data groups use the GDS management class (GDSMC) for the following results:

Changed data sets are automatically backed up every day.
One backup version is retained while the data set exists.
One backup version is retained for 14 days after the data set is deleted.
No extra backup versions ever exist.
Only DFSMShsm-authorized users can issue commands to back up data sets.
Automatic backup processing backs up data sets.
Concurrent copy is not used.

Figure 1 shows the management class attributes for GDSMC.
