Enabling Spool Copy

A spool copy is used as a temporary holding area for protected data until the data is copied to an active synchronous copy. We recommend to enable spool copy option on a copy that has disk library configured, and there are limited resources and capacity available on the disk. Spool copy has a retention rule of 0 days and 0 cycles. Hence, when an Auxiliary Copy job is run:

  • All the data (backup jobs) on the spool copy is copied to the secondary copy.
  • The data on the spool copy is pruned immediately and the space on the spool copy is available for the new backup jobs.

Consider the following before enabling a spool copy:

  • A primary copy or secondary copy can be defined as a spool copy only when there is an active synchronous copy for the storage policy.
  • Spool Copy feature is not supported on storage policy copies enabled with Deduplication or Silo Storage.
  • The DDB backup jobs ignore the spool copy retention rules, and follows the DDB backup pruning. See DDB Backup Pruning Process for more information.
  • For NAS data backed up using IntelliSnap backup: For NAS NetApp and Isilon NAS agents, 1 job is retained when the primary snap copy is configured with spool retention. Other agents have the retention rule set to 0 days and 0 cycles.

Note: Deduplication enabled storage policy copies cannot be configured as spool copies.

Applies To

Synchronous Copy, Selective Copy, Inline Copy, Parallel Copy, Snapshot Copy and WORM Copy.


  1. Before enabling spool copy option on a storage policy copy, ensure that the storage policy copy is assigned as a source to another active synchronous copy.

    See Specify the Source for the Copy for instructions.

  2. From the CommCell Browser, go to Policies > Storage Policies ><Storage Policy>.
  3. Right-click the storage policy copy that was assigned as a source, and click Properties.
  4. In the Copy Properties dialog box, click the Retention tab, click Spool Copy (No Retention), and then click OK.

    A message appears that tells you that enabling spool copy will age data as soon as the Auxiliary Copy job is run.

  5. Click Yes to continue.
