Patent ID: 8583607

Claim:
A method for use in managing deduplication density, the method comprising: receiving a request to deduplicate a first data object; determining a candidate data object for deduplicating the first data object; based on the determination, evaluating a deduplication density of the candidate data object, wherein the deduplication density is indicated by a number of deduplicated data objects represented by the candidate data object, wherein metadata of the candidate data object includes the deduplication density for the candidate data object; based on the deduplication density of the candidate data object, skip deduplicating the first data object to the candidate data object; and based on the deduplication density of the candidate data object, using the first data object for deduplicating additional candidate data objects to the first data object, wherein the first data object is used in addition to the candidate data object for deduplicating the additional candidate data objects.
