Claim 6:
7. A non-transitory computer-readable media comprising executable instructions, wherein a method is implement in response to executing the instructions, the method comprising:
creating a deduplicated copy of data objects, the creating comprising:
receiving a copy of the data objects;
deduplicating the copy, wherein deduplicating the copy comprises:
