摘要：
A method is used in managing deduplication of data in storage systems. A digest is determined for a data object received for deduplication. A candidate data object is identified for deduplicating the data object. A digest associated with the candidate data object matches the digest associated with the data object. The digest in a digest segment is maintained based on identification of the candidate data object. The digest segment includes a set of digests associated with a set of data blocks identified for deduplication in an ordered arrangement.
