DFSMShsm must determine which data sets are eligible for backup
so that it can schedule the data sets for backup if they migrate or
prevent migration if the migration target volume is a tape volume.
A non-SMS-managed data set is eligible for backup if all of the following
apply:
- The data-set-changed indicator in the data set VTOC entry indicates
that the data set has been changed.
- The volume on which the data set resides has the AUTOBACKUP attribute
in any DFSMShsm host in the system.
- The data set is supported for automatic backup, as indicated in
the availability management data mover support table in z/OS DFSMShsm Implementation and Customization Guide.
