Abstract
Protected data is divided into a plurality of segments. For each segment in the plurality of segments, a fingerprint is generated. The plurality of fingerprints is grouped into group(s) of fingerprints and for each group of fingerprints, a group fingerprint is generated. It is determined if the group fingerprint being processed is stored in a cache and if so, the group fingerprint being processed is flagged as one for which a virtual copy will be performed.
