DFSMSdss can select data sets for dump processing based on their storage, management, and data class names. Because management class is the construct that contains a data set’s availability attributes, you might want to filter on it when selecting data sets for dump processing.

If you want to back up data sets in a particular management class, you can filter on the management class name. For example, if you want to perform incremental backup on data sets in management classes MCNAME1 and MCNAME2, specify the DUMP command as follows:

DUMP   -
    DATASET(INCLUDE(**)  -
             BY((MGMTCLAS,EQ,(MCNAME1,MCNAME2)) (DSCHA,EQ,YES))) -
    OUTDDNAME(OUTVOL1)
