Defining copy pools
Copy Pool Name specifies the name of the copy pool. The maximum length is 23 alphanumeric or national characters, or any combination. With one exception where the underscore character ('_') is also allowed in the combination. The first character can not be numeric or underscore.
DFSMShsm manages the use of volume-level fast replication functions, such as FlashCopy® and SnapShot. These functions provide point-in-time copy services that can quickly copy data from a source location to a target location. Using a copy pool, you can specify the pool storage groups that you want DFSMShsm to process collectively for fast replication.
After you define a copy pool and a copy pool backup storage group, you can use DFSMShsm commands to prepare, create, recover, and delete fast replication backup versions. See Defining storage groups to learn how to define a copy pool backup storage group.
