  • Use of data images to allow release of unneeded data storage
    Patent number: 7788456
    Abstract: Use of data images to allow release of unneeded data storage. An embodiment of a method includes generating a series of archives of a set of data, each archive of the series of archives being stored in a data storage. The method further includes releasing an older archive in the series of archives from the data storage after a new archive in the series of archives is generated. A point-in-time image of the data storage is generated after each new archive in the series of archives is generated, with the data captured by the image including data contained in the new archive.

  • Method and system for reducing the number of read-only, persistent point-in-time images on a storage server
    Patent number: 7725436
    Abstract: A plurality of read-only, persistent point-in-time images (RPPIs) of a file system are maintained on a storage server. Each of these RPPIs is created to capture an update of the file system. The file system has at least one subset. If, for each subset of the file system, the file system has an RPPI, other than a first RPPI, having a corresponding subset identical to the first RPPI's corresponding subset, the first RPPI may be deleted, yet all updates captured by the first RPPI are still maintained by other RPPI or RPPIs.
