Patent number: 10884670Abstract: Methods, computer systems, and computer program products for processing data a computing environment are provided. The computer environment for data deduplication storage receives a plurality of write operations for deduplication storage of the data. The data is buffered in a plurality of buffers with overflow temporarily stored to a memory hierarchy when the data received for deduplication storage is sequential or non sequential. The data is accumulated and updated in the plurality of buffers per a data structure, the data structure serving as a fragment map between the plurality of buffers and a plurality of user file locations. The data is restructured in the plurality of buffers to form a complete sequence of a required sequence size. The data is provided as at least one stream to a stream-based deduplication algorithm for processing and storage.Type: GrantFiled: February 14, 2018Date of Patent: January 5, 2021Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Shay H. Akirav, Ron Edelstein, Michael Hirsch, Ariel J. Ish-Shalom, Liran Loya, Itai Tzur

Patent number: 9626374Abstract: For optimizing a partition of a data block into matching and non-matching segments in data deduplication using a processor device in a computing environment, a sequence of matching segments is split into sub-parts for obtaining a globally optimal subset, to which an optimal calculation is applied. The solutions of optimal calculations for the entire range of the sequence are combined, and a globally optimal subset is built by means of a first two-dimensional table represented by a matrix C[i,j], and storing a representation of the globally optimal subset in a second two-dimensional table represented by a matrix PS[i,j] that holds, at entry [i,j] of the matrix, the globally optimal subset for a plurality of parameters in form of a bit-string of length j?i+1, wherein i and j are indices of bit positions corresponding to segments.Type: GrantFiled: December 4, 2014Date of Patent: April 18, 2017Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Michael Hirsch, Ariel J.

Patent number: 8880482Abstract: Various embodiments for replicating deduplicated data using a processor device are provided. A block of the deduplicated data, created in a source repository, is assigned a global block identifier (ID) unique in a grid set inclusive of the source repository. The global block ID is generated using at least one unique identification value of the block, a containing grid of the grid set, and the source repository. The global block ID is transmitted from the source repository to a target repository. If the target repository determines the global block ID is associated with an existing block of the deduplicated data located within the target repository, the block is not transmitted to the target repository during a subsequent replication process.Type: GrantFiled: January 2, 2013Date of Patent: November 4, 2014Assignee: International Business Machines CorporationInventors: Shay H.
