Can I perform availability management tasks?

Although DFSMShsm performs backup and dump tasks automatically, you can perform availability management tasks on your own data sets by issuing the following DFSMShsm user commands through ISMF online panels, TSO, TSO/E, or a user macro. Inline backup is also available for backing up data sets.

Availability Management User Commands	DFSMShsm Functions
HALTERDS	Changes the minimum backup frequency and number of backup versions kept for one or more data sets. Cannot be used on SMS-managed data sets, which are controlled by the data sets’ management class parameters. If used on SMS-managed data sets, the command fails and an error message is issued.
HBACKDS	Creates a backup version of one or more data sets.
HBDELETE	Deletes specific backup versions of one or more data sets.
HLIST	Lists information from the migration and backup control data sets.
HQUERY	Lists outstanding DFSMShsm requests.
