The HBACKDS form of the command can be used by either non-DFSMShsm-authorized or DFSMShsm-authorized users. The BACKDS form of the command can be used only by DFSMShsm-authorized users. The UNIT and VOLUME parameters are required because DFSMShsm cannot locate an uncataloged data set without being told where it is.
