For data sets that have value as long as they are used but lose
value quickly when they are not used, the no migration (NOMIGMC) management
class has been defined. Data sets that use this management class receive
the following processing:
- The data sets are not backed up automatically.
- Both DFSMShsm-authorized and non-DFSMShsm-authorized users can
issue commands to back up data sets.
- If a data set is backed up by command, one backup version is retained
for 30 days after the data set is deleted.
- Concurrent copy is not used.
Figure 1 shows the attributes for NOMIGMC.
