CA Assigned Patent

CA, Inc., Islandia, NY, has been assigned a patent (8,583,599) for “reducing data duplication in cloud storage” developed by Hui Zhao, Beijing, China.

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Data duplication may be reduced in cloud storage. First snapshots of one or more remote volumes may be received via a network. Responsive to and/or based on the first snapshots, unique clusters and duplicate clusters may be identified among the valid clusters of the remote volumes. The unique clusters and single instances of the duplicate clusters may be stored in a backup file, such that the backup file is devoid of duplicate clusters. Second snapshots of the one or more remote volumes may be received via the network. Responsive to the second snapshots, the clusters in the backup file that are no longer valid may be utilized to store the valid clusters in the one or more remote volumes not yet stored in the backup file.”

The patent application was filed on November 29, 2010 (12/955,648).
