Abstract
Disclosed is a method of operating a data identification system. The method comprises identifying a first plurality of changed blocks in a first primary storage volume, processing the first plurality of changed blocks to generate a first plurality of fingerprints, scanning a first plurality of data items stored in a first secondary storage volume within the first primary storage volume corresponding to the first plurality of changed blocks to identify a first infected data item of the first plurality of data items, identifying a first reference fingerprint from the first plurality of fingerprints corresponding to the first infected data item, identifying a second plurality of changed blocks in a second primary storage volume corresponding to a second plurality of data items stored in a second secondary storage volume within the second primary storage volume, processing the second plurality of changed blocks to generate a second plurality of fingerprints, and identifying a first target fingerprint from the second plurality of fingerprints that corresponds to the first reference fingerprint.
