About scratch volume pools

A scratch pool is an optional volume pool that you can use to ensure that volumes are allocated to the volume pools that need them. Media Manager moves volumes from a scratch pool to other pools that do not have volumes available, including Vault pools. Expired volumes are returned to the scratch pool automatically.

You can set up a scratch pool in two ways, as follows:

The scratch pool feature can affect reports for media coming on site. If you use a scratch pool, the Picking List for Vault, the Offsite Inventory, and the All Media Inventory reports may include volumes from other profiles or vaults that have expired and moved back into the scratch pool even though the reports may be for a specific Vault profile or session.

For information about configuring scratch pools, see the NetBackup Administrator's Guide.
