Abstract: A virtual computing system deduplicates data. The system includes one or more processors, and one or more computer-readable storage media communicably coupled to the one or more processors. The one or more computer-readable storage media has instructions stored thereon that, when executed by the one or more processors, cause the one or more processors to: scan extents for duplicate data chunks; calculate hash values for the extents at different chunk lengths; emit the hash values at the different chunk lengths; identify matching ones of the hash values; and select one or more candidates from among the matching ones of the hash values for dedup.
