  • Patent number: 10031816
    Abstract: The disclosed computer-implemented method for healing images in deduplication storage may include (i) detecting that a data segment stored within deduplication storage is corrupted by executing an algorithm on the data segment to generate a numerical identifier for the data segment and determining that the numerical identifier does not match a previously stored numerical identifier for the data segment, (ii) checking, during a backup operation, whether a digital fingerprint of a data segment of an image being backed up matches a digital fingerprint of the corrupted data segment that was taken prior to corruption and that is already stored within the deduplication storage, and (iii) appending the data segment from the image being backed up to a container that already contains the corrupted data segment rather than replacing the corrupted data segment. Various other methods, systems, and computer-readable media are also disclosed.

  • Patent number: 9495379
    Abstract: The present disclosure provides for implementing a two-level fingerprint caching scheme for a client cache and a server cache. The client cache hit ratio can be improved by pre-populating the client cache with fingerprints that are relevant to the client. Relevant fingerprints include fingerprints used during a recent time period (e.g., fingerprints of segments that are included in the last full backup image and any following incremental backup images created for the client after the last full backup image), and thus are referred to as fingerprints with good temporal locality. Relevant fingerprints also include fingerprints associated with a storage container that has good spatial locality, and thus are referred to as fingerprints with good spatial locality. A pre-set threshold established for the client cache (e.g., threshold Tc) is used to determine whether a storage container (and thus fingerprints associated with the storage container) has good spatial locality.
