Abstract
One embodiment provides a computer implemented method of data identification within a deduplication storage system, the method comprising processing multiple units of a segment of data within the deduplication storage system using a fingerprint generation algorithm; storing the internal state generated while processing the multiple units of the segment of data; generating a first fingerprint for the segment of data based on the internal state; reloading the internal state after generating the first fingerprint for the segment of data; and generating a second fingerprint for the segment of data based on a transformed unit of the segment of data.
