Patent ID: 8161003

Claim:
A non-transitory computer-readable memory storing instructions, which, when executed by a computer, perform a method for copying data stored in a first copy data set, the method comprising: identifying, in the first copy data set, a data item satisfying a selection criterion based at least in part on a data-specific ID, wherein the data-specific ID is associated with a software application for the data item or is associated with a file type for the data item; and copying to a second copy data set at least a portion of the data item, wherein the copying is based on one of at least two differing storage preferences, and wherein the one storage preference is based on the data-specific ID, indicating that the data item satisfies the selection criteria, wherein the data item indicated is de-indicated after the data item is copied to the second copy data set, and wherein the data item indicated will not be pruned by a pruning program unless the data item is first de-indicated.
