Abstract
A computer-implemented technique performs block deduplication. The technique involves generating a list of candidate blocks and adding classifications to the list of candidate blocks. The classifications classify the candidate blocks on the list into different categories based on a set of block sequence matching criteria. The technique further involves performing, based on the classifications added to the list of candidate blocks, further block deduplication processing on first candidate blocks having a first classification while not performing further block deduplication processing on second candidate blocks having a second classification. Examples of the categories include an 'exact long match' category, a 'disrupted long match' category, a “loosely long match” category, and a “short match” category.
