A comparison module compares the rolling hash value with entries stored in a rolling hash index, and in response to matching the rolling hash value with an entry in the rolling hash index, generates a strong hash value and determines if a match of the strong hash value exists in a first strong hash index. The comparison module, in response to a determination that the match does not exist in the first strong hash index, compares the strong hash value with entries in a second strong hash index in the remote data repository. A migration module, in response to a determination that the strong hash value does not match any hash entries, stores the portion of backup data as new data."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Similarity based deduplication for secondary storage","description":"For similarity based deduplication of remote data repositories, a parse module generates a rolling hash value based on a portion of an incoming stream of backup data.
