Creating a Secondary Silo Copy

You can use the secondary silo copy to make the additional copies of the deduplicated data. A secondary silo copy preserves the data deduplication in the silo storage.

Alternatively, you can create a secondary silo copy by using the sp_copycreation.xml configuration file. For more information, see Creating a Secondary Silo Copy.


  • Secondary copies are automatically associated with the System Created Autocopy schedule policy.

    The system created automatic copy schedule repeatedly runs the auxiliary copy job everyday, at 30 minute time intervals.

  • The copy is automatically associated to a pre-existing schedule of the storage policy, if the schedule was created with the All Copies option enabled. See System Created Automatic Auxiliary Copy Schedule Policy for more information.


  1. From the CommCell Browser, expand Policies > Storage Policies > storage_policy.
  2. Right-click the silo copy and then click All Tasks > Create Secondary Silo Copy.
  3. In the Copy Properties dialog box, enter the appropriate information:
    1. In the Copy Name box, type the name for the copy.
