Command availability management
Previous topics have described how you can automatically cause
DFSMShsm to dump and back up your data sets. However, you may want
to dump a volume or back up data sets or volumes at a time other than
when automatic availability management would cause the backup or dump.
Also, when a data set or volume is damaged, either physically or logically,
you want to access the dumped or backed up versions to replace the
damaged data. Command availability management allows you to accomplish
these functions. You can perform the following tasks using availability
management commands:
- Dump a volume to either the dump classes specified in the command or the dump classes specified in the storage group
- Dump the volumes in one or more storage groups
- Back up an individual data set
- Use the data set backup by command capabilities
- Back up all eligible changed data sets on a volume
- Back up all eligible changed data sets in one or more storage groups
- Back up all supported data sets on a volume
- Back up all supported data sets in one or more storage groups
- Delete expired backup versions from the backup volumes
- Delete specific backup versions from the backup volumes
- Recover an individual data set from either a dump copy or an incremental backup version, whichever is the more recent
- Recover an individual data set from an incremental backup version
- Recover an individual data set from a dump copy
- Restore a complete volume from a dump copy and update the data sets from the latest incremental backup versions
- Restore a complete volume from a dump copy
- Recover a volume by using only incremental backup versions
