The commands for backing up SMS-managed and non-SMS-managed data sets are different. When you are backing up SMS-managed data sets, the SMS management class attributes that are used in your computing center direct whether DFSMShsm creates your backup version. With the TARGET keyword, you can direct the backup to a specific device when you are backing up either SMS or non-SMS data sets. The CC keyword also works for both SMS and non-SMS data sets.

All allocations to a data set are freed before requesting service from DFSMShsm when HBACKDS is issued from your TSO address space. This includes REXX programs that invoke the HBACKDS command.
