Abstract: A method, system, and computer program product are provided for determining the recovery readiness of a data asset. A set of metrics are identified for a current recovery operation performed for the data asset and a current recovery objective is identified for the data asset. The current recovery operation is applied to the data asset using the set of metrics. A determination is made as to whether the current recovery operation meets the recovery objective for the data asset. Responsive to a failure of the current recovery operation to meet the recovery objective, an error is presented indicating the failure and a determination is made as to whether a different recovery policy may be implemented to meet the recovery objective for the data asset. If a different recovery policy exists that meets the recovery objective for the data asset, the different recovery policy is implemented.

Abstract: A state machine implemented controller is provided in which a logic core 20 is reconfigurable in response to state data held within a memory 22. Thus, on transition from one state to a next state the data held within the memory 22 is used to reconfigure the operation of the logic core 20. This enables a relatively compact logic core 20 to be used time and time again, thereby avoiding the need to individually define a logic core appropriate to each individual one of the states that the state machine can enter into. This results in a controller which is much more compact on an integrated circuit die than is the case with prior art controllers.

Abstract: A method for generating file copies with minimal mounting and positioning of storage volumes involves receiving a request to generate file copies specifying file selection criteria, identifying matching files meeting the selection criteria, locating the matching files on their storage volumes, and copying the files to a copy set. Determination of file copying order is optimized by placing greater emphasis on relative storage locations of matching files than on the order in which their copies are requested. Once a storage volume is mounted, all files stored on that volume are matched against the pending requests including future requests and if found to be the subject of a request, are copied from the mounted volume in optimal position-sensitive order. Copying from secondary storage is deferred until all copying from primary storage is complete.
