dsname: Specifying the name of the data set to be backed up

Explanation: dsname is a required positional parameter specifying the fully qualified name of the data set you want DFSMShsm to back up. For dsname, substitute the fully qualified name of the data set.

Defaults: None.
Note:
  1. Because dsname is a required positional parameter, you must specify it immediately after the command name. You cannot specify an alias for dsname. If you do, DFSMShsm does not backup the data set.
  2. The volume where the data set resides must be mounted before you issue the BACKDS command.
  3. DFSMShsm does not handle partitioned data set members individually. a member name of a partitioned data set, DFSMShsm backs up the entire partitioned data set.
