  • Method and apparatus for data deduplication
    Patent number: 11243915
    Abstract: A current file is obtained in the data. It is determined whether a similar historical file exists based on a sampled data block from at least one predetermined location in the current file. In response to non-existence of the similar historical file, the current file and corresponding metadata are stored on a file basis. In response to existence of the similar historical file, a deduplication operation is applied on the current file on a block basis.
    Type: Grant
    Filed: August 28, 2018
    Date of Patent: February 8, 2022
    Assignee: International Business Machines Corporation
    Inventors: Min Fang, JiaYang Zheng, GuoFeng Zhu

  • Concurrent data retrieval in networked environments
    Patent number: 10031807
    Abstract: Embodiments of the present invention provide methods, systems, and program products for concurrent data retrieval from multiple loud storage devices. Embodiments of the present invention can be used to retrieve stripes of target data from at least a first network device, retrieve redundancy data of the target data from a second network storage device that is different from the first network storage device concurrently and reconstructing the target data based on the stripes of the target data and the redundancy data.
