Examples of how to code the BACKVOL command for SMS-managed volumes

The following examples present different ways to code the BACKVOL command for SMS-managed volumes:

Note: Any values specified here are only examples and should not be interpreted as the values to be used for your system.

Backing up control data sets

In this example, control data sets are backed up to DASD, using DFSMSdss as the datamover.

   BACKVOL CONTROLDATASETS(BACKUPDEVICECATEGORY(DASD) DATAMOVER(DSS))

Nulling the journal

In this example, the journal is nulled and the control data sets are not backed up.

   BACKVOL CONTROLDATASETS(NULLJOURNALONLY)

Backing up all the data sets on an SMS-managed volume

In this example, all the data sets on an SMS-managed volume are backed up if their management class attributes allow command backup. Because you did not specify TERMINAL, the data set backup messages go only to the backup activity log.

   BACKVOL VOLUMES(SMS025) TOTAL

Backing up eligible data sets on an SMS-managed volume

In this example, the eligible data sets, as defined by their management-class attributes, are backed up. The backup versions of these data sets will reside on tape. The data set backup messages appear at the system console and in the backup activity log.

   BACKVOL VOLUMES(VOL003) INCREMENTAL TERMINAL  +
           BACKUPDEVICECATEGORY(TAPE)

Dumping an SMS-managed volume to a specified dump class and retention period

In this example, an SMS-managed volume, SMS13, is dumped to a specific class, EXTRA, and the dump copy is assigned a retention period of 10 days.

   BACKVOL VOLUMES(SMS13)  +
           DUMP(DUMPCLASS(EXTRA) RETENTIONPERIOD(10))

Dumping an SMS-managed volume to a dump class

In this example, the volume SMS13 is dumped to a dump class called OLDCLASS. The retention period is taken from the definition of class OLDCLASS.

   BACKVOL VOLUMES(SMS13) DUMP(DUMPCLASS(OLDCLASS))

In this example, the volume SMS13 is dumped to the dump classes associated with its storage group definition.

   BACKVOL VOLUMES(SMS13) DUMP

In this example, five dump copies are made of volume SMS13. The retention periods for the first three dump copies are the retention periods from the corresponding dump classes. The retention period for the fourth dump copy is 60 days. The retention period for the fifth dump class is unlimited.

   BACKVOL VOLUMES(SMS13)  +
           DUMP(DUMPCLASS(WK,MNTH,DLY,VITREC,SPEC)  +
                RETENTIONPERIOD(*,*,*,60,NOLIMIT))

Backing up all defined control data sets

The following example shows how to code the BACKVOL command to back up all defined control data sets.

   BACKVOL CONTROLDATASETS

Backing up data sets in several storage groups

In this example, all the supported data sets on the volumes in the storage groups: HSMONE, HSMTWO, and HSMFOUR are to be backed up by DFSMShsm.

   BACKVOL STORAGEGROUP(HSMONE,HSMTWO,HSMFOUR) TOTAL

Dumping all volumes of a storage group to a specific dump class

In this example, DFSMShsm dumps all volumes in storage group, SGSMALL. The dump stacking and retention options are obtained from the definition of dump class, SPECIAL.

   BACKVOL STORAGEGROUP(SGSMALL) DUMP(DUMPCLASS(SPECIAL))
