In this example, you are issuing the HALTERDS command to change the number of backup versions for the data set CRPA.PARTSTST.CNTL to the maximum allowable number of versions (29) for a BCDS record length of 2040, and the number of days between backup versions to the minimum number of days (0). You are changing the frequency of creation of backup versions of the data set so that DFSMShsm creates a backup version every day during automatic backup, provided you changed the data set.
