Restrictions

Because dsname is a required positional parameter, you must specify it immediately after HBACKDS.
The volume on which the data set resides must be mounted before you issue the command.
DFSMShsm does not process individual partitioned data set members. If you specify a partitioned data set name with a member name, message ARC1065I is issued and nothing is backed up.
If dsname is fully qualified and refers to a VSAM data set, specify the base cluster name. The entire VSAM data set will be backed up.
When you specify a password with a filter, all the password-protected data sets affected must have the same password. Otherwise, DFSMShsm authorization checking fails the backup of those password-protected data sets that are protected by some other password.
