About NetBackup volume pools
A volume pool identifies a set of volumes by usage. Volume pools protect volumes from access by unauthorized users, groups, or applications. When you add media to NetBackup, you assign them to a volume pool (or assign them as standalone volumes, without a pool assignment).
By default, NetBackup creates the following volume pools:
You can add other volume pools. For example, you can add a volume pool for each storage application you use. Then, as you add volumes to use with an application, you assign them to that application's volume pool. You can also move volumes between pools.
You also can configure a scratch pool from which NetBackup can transfer volumes when a volume pool has no volumes available.
The volume pool concept is relevant only for tape storage units and does not apply to disk storage units.
You can use any of the approved characters for volume pools names.
See NetBackup naming conventions.
NetBackup uses several special prefixes for volume pool names.
Examples of volume pool usage are available in the NetBackup Administrator's Guide, Volume II:
