Command recovery and restore

You use the recovery and restore process to:

Recover a data set that has been lost or damaged
Access an earlier version of the data set without deleting the current version
Restore a data set from a dump copy
Restore a volume from a dump copy and update it from incremental backup versions
Restore a volume from a full-volume dump
Recover a volume from DFSMShsm backup versions

The recovered backup version can replace an existing data set, or you can rename the recovered copy so it exists in parallel with the current data set. You can recover or restore a data set or volume only by specifying the RECOVER command.

A backup extended format VSAM data set can be recovered only as an extended format data set.

If the data set was RACF® indicated at the time that the dump or backup version was created or is RACF indicated at the time of the recovery or restore, DFSMShsm recovers a discrete profile for the recovered or restored data set. See Recovering or restoring RACF-indicated data sets for a discussion of profile recovery.

If you want to use DFSMShsm recovery, you must have specified SETSYS BACKUP.

The recovery process has two restrictions:

DFSMShsm cannot recover a data set to a migration volume
DFSMShsm cannot recover a data set that is currently marked as migrated in the computing system catalog, unless the data set is non-VSAM, a recover data set name is issued with NEWNAME specified, and the NEWNAME data set is not a migrated data set.
