Abstract
A method of performing deduplication includes (1) receiving a write command that specifies a set of data, the set of data including multiple blocks of data, (2) hashing a subset of the set of data, yielding a representative digest of the set of data, and (3) performing deduplication on the set of data based at least in part on matching the representative digest to a digest already stored in a database which relates digests to locations of data from which the digests were produced. An apparatus, system, and computer program product for performing a similar method are also provided.
