Copy pools

The BACKUP SYSTEM utility uses copy pools. A copy pool is a defined set of storage groups that contain data that DFSMShsm can back up and recover collectively. Each of these storage groups contains the name of the associated backup storage group for storing the backup.

Each DB2® subsystem can have up to two copy pools, one for databases and one for logs. BACKUP SYSTEM copies the volumes that are associated with these copy pools at the time of the copy.

You must define any needed copy pools before you run BACKUP SYSTEM. You must at least define a database copy pool, and that definition must include the ICF catalog names. (You can add the ICF catalog names to the database copy pool definition by altering the copy pools.) If you plan to also copy the logs, define another copy pool for your logs.

Use the following DB2 naming convention when you define the required copy pools:

DSN$locn-name$cp-type

where:

DSN

The unique DB2 product identifier.

$

A delimiter. You must use the dollar sign character ($).

locn-name

The DB2 location name.

cp-type

The copy pool type. Use DB for database and LG for log.
