The method includes accessing, within an electronic system, a plurality of files in a primary storage filesystem and determining a plurality of fingerprints for the plurality of files. Each respective fingerprint may correspond to a respective portion of a respective file of the plurality of files. The method further includes determining a plurality of portions of the plurality of files where each of the plurality of portions has the same corresponding fingerprint and accessing a list comprising a plurality of portions of files previously deduplicated. A portion of a file of the plurality of files not present in the list may then be deduplicated. Consecutive portions of variables lengths having the same corresponding fingerprints may also be deduplicated."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for filesystem deduplication using variable length sharing","description":"Embodiments of the present invention are directed to a method and system for filesystem deduplication that uses both small fingerprint granularity and variable length sharing techniques.
