Abstract
Techniques for processing data may include: receiving a candidate block; performing partial deduplication processing of the candidate block; receiving a second candidate block subsequent to performing partial deduplication processing for the candidate block; and performing first processing to determine whether to perform promotion processing for the entry, The partial deduplication processing may include: partially deduplicating at least one sub-block of the candidate block; and creating an entry in a deduplication database for the candidate block, wherein the entry includes a digest of the candidate block and the entry denotes a potential target block having the digest, and wherein the entry includes a counter that tracks a number of missed full block deduplications between the potential target block and subsequently processed candidate blocks. The promotion processing promotes the potential target block, having the first digest of the entry, to a new target block.
