  • Recovering from a backup copy of data in a multi-site storage system
    Patent number: 8214685
    Abstract: To make available a backup copy of source data in a multi-site storage system, the source data is provided at a first storage site and an operational copy of the source data is provided at a second storage site. In response to a request to create a backup copy of the source data, the backup copy of the source data is produced at each of the first and second storage sites. In response to failure that causes the first storage site to be unavailable, recovery of a version of the source data is enabled based on accessing the backup copy of the source data at the second storage site, and accessing the operational copy of the source data at the second storage site.

  • Restoring data to a point in a continuum of input/output operations
    Patent number: 7937506
    Abstract: To restore data, substantially continuous recording of input/output (I/O) operations in a storage system is performed to provide an I/O continuum of I/O operations. Based on analyzing activity associated with the storage system, points in the I/O continuum associated with valid data are identified. Data in the storage system is restored to one of the identified points.
