  • Distributed client side deduplication index cache
    Patent number: 11372814
    Abstract: Systems and methods for deduplicating data are provided. An index used in deduplicating data is distributed to clients. The clients can use the distributed index to provide hints as to whether the data is deduplicated at the server. The server may be associated with a main index used to confirm whether the data is deduplicated based on the hints.
    Type: Grant
    Filed: March 20, 2020
    Date of Patent: June 28, 2022
    Assignee: EMC IP HOLDING COMPANY LLC
    Inventors: Dilip N. Simha, Thomas Sandholm, Julio Lopez

  • Random extraction from compressed data
    Patent number: 9059728
    Abstract: Aspects of the invention are provided for decoding a selected span of data within a compressed code stream. A selection of data within the compressed code stream from an arbitrary position is presented for decompression. The arbitrary position is the starting point in the compressed code stream for decompression, and a phrase within the compressed code stream containing the starting point is identified. From the arbitrary starting point, a back pointer may provide direction to the literal. The literal is extracted as a decoding of the compressed data associated with the starting point.
