Abstract
A method, computer program product, and computing system for performing an entropy analysis on each of a plurality of candidate data chunks associated with a potential candidate to generate a plurality of candidate data chunk entropies; performing an entropy analysis on each of a plurality of target data chunks associated with a potential target to generate a plurality of target data chunk entropies; identifying a candidate data chunk entropy limit, chosen from the plurality of candidate data chunk entropies, and a target data chunk entropy limit, chosen from the plurality of candidate data chunk entropies; and comparing a specific candidate data chunk associated with the candidate data chunk entropy limit to a specific target data chunk associated with the target data chunk entropy limit to determine if the specific candidate data chunk and the specific target data chunk are identical.
