One example method includes computing a first hash for a chunk for which a duplicate determination is to be made. The first hash is suitable for making the duplicate chunk determination. The method also includes computing a delta hash for the chunk. The delta hash is suitable for making a delta chunk determination. The method controls a de-duplication logic to process the chunk as a duplicate upon determining that the first hash matches a stored first hash. The method controls the de-duplication logic to process the chunk as a delta chunk upon determining that the first hash does not match a stored first hash and that the delta hash matches a stored delta hash. Processing a chunk as a delta chunk may include storing a reference to a stored chunk and storing delta hash information."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Delta chunks and delta hashes","description":"Example apparatus, methods, and computers control processing delta chunks with delta hashes.
