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.
Notes:
-
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.
