Abstract
Techniques described herein elect how data is deduplicated in a storage system. A similarity hash signature for a data unit is calculated. A digest table is searched for a similarity hash signature within a predetermined distance of the similarity hash signature for the data unit. Based on the search, either a similarity hash signature or a strong hash signature of the data unit is added to the digest table.
