  • Patent number: 10452617
    Abstract: A method, a system, and a computer-implemented method for performing multi-level deduplication of data are disclosed. A zone stamp is generated for each zone in a plurality of zones contained in at least one data stream. The zone stamp is compared to another zone stamp. The zone stamp and another zone stamp represent zones in the plurality of zones. The comparison is performed for zones at corresponding zone levels based on a determination that a zone stamp of a zone of a preceding zone level is not similar to another zone stamp of another preceding zone level. The zone at the preceding zone level includes at least one zone of a next zone level having a size smaller than or equal to a size of the zone of the preceding zone level. The zone and another zone are deduplicated based on a determination that the zone stamp is similar to another zone stamp.

  • Publication number: 20190266131
    Abstract: A system, a method, and a computer program product for performing deduplication of data using a scalable deduplication grid are disclosed. A listing of a plurality of zone stamps is generated, where each zone stamp represents a zone in the plurality of zones in a data stream. The listing contains a logical arrangement of the plurality of zone stamps obtained from each storage location and being accessible by a plurality of servers. A first zone stamp in the listing is compared to a second zone stamp in the listing. The first and second zones are delta-compressed based on a determination that the first zone stamp is substantially similar to the second zone stamp. A server is selected to perform the comparison and delta-compression.

  • Patent number: 10067946
    Abstract: A method, a system, and a computer program product for performing next level multi-level deduplication. A first zone stamp for a first data zone is generated and compared to a second zone stamp representing a second data zone, where the zones are first level data zones. The first and second data zones are deduplicated when the first zone stamp matches the second zone stamp. A second-level first zone stamp is selected when there is no match between first and second zone stamps. The second-level first zone stamp, representing a second-level first data zone in the first data zone, is compared to the second zone stamp and/or a second-level second zone stamp representing a second-level second data zone. The second-level first zone and one of the second data zone and the second-level second zone are deduplicated when the second-level first zone stamp matches one of the second zone stamp and the second-level second zone stamp.
