Explanation: DASDBACKUP (NO | YES) are mutually exclusive, optional subparameters of the ZCOMPRESS parameter, specifying whether or not to use zEDC Services when DFSMShsm backs up to DASD.
Subparameter | Explanation |
---|---|
DASDBACKUP (NO) | DFSMShsm does not use zEDC for a data set backup to DASD. DFSMShsm will use the SETSYS COMPACT settings. |
DASDBACKUP (YES) | DFSMShsm will use zEDC Services during backup to DASD, if this function is supported by the system. If zEDC is not available, DFSMShsm will use the SETSYS COMPACT settings to determine what type of software compaction is used for backup. |
SMS relationship: Parameter differs in meaning when applied to SMS-managed or non-SMS-managed DASD volumes or data sets.
SETSYS default: None.
