Creating a Storage Policy Copy with Deduplication

You can create a storage policy copy with deduplication, as an efficient method to store data that identifies and eliminates duplicate blocks of data during backups.

Optionally, you can also create a storage policy copy with deduplication by using the sp_copycreation.xml configuration file, which contains parameters that define the storage policy copy. For more information, see Creating a Deduplication Enabled Storage Policy Copy.


  • The number of deduplication database (DDB) partitions on the MediaAgent that you select should not exceed the system threshold of 30 DDB partitions.
  • 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.
