Creating a Storage Policy Copy with Global Deduplication

You can create a storage policy copy with deduplication and assign it to a global deduplication policy.

Before You Begin

Before assigning a storage policy copy to a global deduplication policy, consider these guidelines:

  • Global deduplication policy must be assigned at the time of storage policy or copy creation.

    When assigned, you can neither change nor disable global deduplication policy.

  • Existing storage policy copies cannot be configured for global deduplication.
  • Also, no two storage policy copies in a storage policy can be associated with the same global deduplication policy.
  • When configuring global deduplication between copies, ensure that the MediaAgents of all copies have access to the DDB.
  • If multiple MediaAgents are used, then the disk library that contains the DDB must be configured as a static share library.


  1. From the CommCell Browser, expand Policies > Storage Policies.
  2. Right-click the appropriate storage policy and then click All Tasks > Create New Copy.
  3. In the Copy Properties dialog box, enter the appropriate information.
    1. In the Copy Name box, type a name for the copy.
    2. From the Library list, select the disk library.
    3. From the MediaAgent list, select the name of a MediaAgent.
    4. Select the Global Deduplication Policy check box, and then select the name of a global deduplication policy from the list.
    5. Click OK.
  4. In the Auxiliary Copy Schedule dialog box, click OK to accept the default schedule.

    The storage policy copy appears under the appropriate storage policy.
