Abstract: An embodiment of a method of restoring data begins with a step of restoring point-in-time data from a local copy. The method concludes with a step of restoring at least a portion of an incremental difference between the point-in-time data and a desired state of the data from a remote mirror.

Abstract: An embodiment of a method of designing a storage system begins with a step of assigning decision variables to a range of candidate storage systems. Each of the decision variables identifies a single candidate storage system. The method concludes with a step of employing the decision variables in a mathematical program to determine which of the candidate storage systems meets availability and reliability criteria and incurs a near minimal projected cost.

Abstract: An embodiment of a method of restoring backup data comprises first and second steps that preferably are executed at least partially in parallel. The first step restores an incremental backup. The second step selectively restores a full backup. The selective restoration of the full backup disregards units of data that were restored from the incremental backup and restores a remainder of the full backup. In an alternative embodiment, the first step precedes the second step. In another alternative embodiment, the selective restoration of the full backup accesses a table that indicates the units of data contained in the incremental backup to determine which units of data to disregard in the full backup.

Abstract: An embodiment of a method of estimating storage system availability begins with a first step of modeling a storage system design in operation under a workload to determine location of retrieval points. The retrieval points provide sources for primary storage recovery for a plurality of failure scenarios. For a particular failure scenario, the method continues with a second step of finding a secondary storage location of a most recent retrieval point relative to a target recovery time that is available for recovery. A third step determines a recovery time for propagation of the most recent retrieval point from the secondary storage location to primary storage.
