摘要： Systems and methods for retrieving data from a storage system having a plurality of storage pools are provided. The method comprises processing configurable data retrieval instructions to determine a first storage pool from which target backup data is to be retrieved, in response to a data restore request; and retrieving the target backup data from the first storage pool to satisfy the restore request. The configurable data retrieval instructions are managed by a source external to the storage system with administrative authority to change the configurable data retrieval instructions to optimize data restoration from the storage system.

摘要： In one aspect of the present description, in connection with storing a first deduplicated data object in a primary storage pool, described operations include determining the duration of time that the first data object has resided in the primary storage pool, and comparing the determined duration of time to a predetermined time interval. In addition, described operations include, after the determined duration of time meets or exceeds the predetermined time interval, determining if the first data object has an extent referenced by another data object, and determining whether to move the first data object from the primary storage pool to a secondary storage pool as a function of whether the first data object has an extent referenced by another data object after the determined duration of time meets or exceeds the predetermined time interval. Other features and aspects may be realized, depending upon the particular application.

摘要： The present invention provides for a method, system, and computer program for the application of data deduplication according to a policy-based strategy of tiered data. The method operates by defining a plurality of data storage policies for data in a deduplication system, policies which may be arranged in tiers. Data objects are classified according to a selected data storage policy and are split into data chunks. If the selected data storage policy for the data object does not allow deduplication, the data chunks are stored in a deduplication pool. If the selected data storage policy for the data object allows deduplication, deduplication is performed. The data storage policy may specify a maximum number of references to data chunks, facilitating storage of new copies of the data chunks when the maximum number of references is met.

摘要： A process is disclosed by which data is securely deleted in a transactionally consistent manner. This may be accomplished by committing a preparation transaction for a data object within a system managing the data object in order to return the system to an initial condition if necessary, attempting to commit an execution transaction with the data object only after committing the preparation transaction, and securely deleting any portion of the data object necessary to return the system to the initial condition if committing the execution transaction fails and to change the system to a completed condition only if committing the execution transaction succeeds. In a delete or move transaction an existing backup object may be assigned a new logically deleted state such that if the delete or move transaction fails, the data will be made accessible again.

摘要： A chunk index has information on chunks in a storage space referenced in objects in the storage space. The chunk index includes a reference count for each chunk indicating a number of objects in which the chunk is referenced and a reference measurement representing a level of data object references to the chunk. One chunk is selected to remove from the storage space based on a criteria applied to the reference measurements of chunks having reference counts indicating that the chunks are not referenced in one object in the storage space.

摘要： LAN-managed storage volumes are managed by a LAN storage manager installed on a storage management server. In processing a LAN-free storage volume request, the LAN tape manager selects a LAN-managed storage volume responsive to the LAN-free storage volume allocation request wherein the LAN-managed storage volume is initialized as a candidate for a LAN-free storage operation. The LAN-managed storage volume may be initialized by the LAN storage manager as a candidate for a LAN-free storage operation prior to the LAN storage manager receiving the LAN-free storage volume allocation request or in response to the LAN storage manager receiving the LAN-free storage volume allocation request. Additionally, prior to being initialized as a candidate for a LAN-free storage operation, the LAN-managed storage volume may be a pre-existing storage volume or a scratch storage volume.

摘要： During execution of an existing scheduling computer program on a client node, an update computer program and a self-describing automatic installation package are downloaded to the client node from a logical depot node implemented on an existing management server. Therefore, advantageously, no physical depot node or other additional computing device is needed for the client node to update itself. Execution of the update computer program is spawned on the client node from the existing scheduling computer program. As such, the update computer program inherits root access to the client node and security credentials to the management server from the scheduling computer program—advantageously, then, a user does not have to perform any laborious configuration of the client node in order to update the node. The client node ultimately updates itself using the self-describing automatic installation package, which includes all the information needed for the client node to update itself.
