摘要： A method and system for integrating migration level two (ML2) and backup tape processing provide for the backup, archival, and/or restoration of ML2 tape files without the use of tape mounts. In this manner, the amount of data movement required to recover from data loss is significantly reduced. Tape files may be recovered to their original status, even if the file has migrated to ML2. The status of the data is preserved after such a recovery operation. In this manner, data movement is reduced because no remigration of data is required after a recovery.

摘要： A data storage hierarchy which inherently allows for a level 1 storage file to be uniquely identified across an entire network is disclosed. A directory naming convention is employed which includes an internal identifier and a name for each subdivision of the network. Because each file can be uniquely identified across the network, a single level 1 storage space in a file space, or a directory therein, can be used for the entire network. Also, because of the inherent uniqueness of the naming system, common DASD control files otherwise required to map between level 1 storage files and their level 0 source files can be eliminated.

摘要： Provided are computer program product, system, and method for restoring deduplicated data objects from sequential backup devices. A server stores data objects of extents having deduplicated data in the at least one sequential backup device. The server receives from a client a request for data objects. The server determines extents stored in the at least one sequential backup device for the requested data objects. The server or client sorts the extents according to an order in which they are stored in the at least one sequential backup device to generate a sort list. The server retrieves the extents from the at least one sequential backup device according to the order in the sort list to access the extents sequentially from the sequential backup device in the order in which they were stored. The server returns the retrieved extents to the client and the client reconstructs the requested data objects from the received extents.

摘要： One aspect of the present invention includes enabling the efficient transfer of deduplicated data between storage pools in a storage management system without unnecessary reassembly and deduplication of data objects. In one embodiment, the storage management system tracks deduplication information for the data chunks of data objects within an index at the storage management system level, in addition to tracking storage information for each data object within another index at the storage management system level. The data chunk deduplication information is then accessible by any storage pool. Accordingly, transfers of the data objects and data chunks of the data object are easily facilitated, even between non-deduplicating and deduplicating storage pools.

摘要： In each of a number of passes to deduplicate a data object, a transaction is started. Where an offset into the object has previously been set, the offset is retrieved; otherwise, the offset is set to reference a beginning of the object. A portion of the object beginning at the offset is deduplicated until an end-of-transaction criterion has been satisfied. The transaction is ended to commit deduplication; where the object has not yet been completely deduplicated, the offset is moved just past where deduplication has already occurred. The object is locked during each pass; other processes cannot access the object during each pass, but can access the object between passes. Each pass is relatively short, so the length of time in which the object is inaccessible is relatively short. By comparison, deduplicating an object within a single pass prevents other processes from accessing the object for a longer time.

摘要： For recovery of data chunks from alternate data stores, a method detects a damaged copy of a first data chunk of a deduplicated data object within a first storage pool of plurality of storage pools storing data chunks. The method further locates an undamaged copy of the first data chunk in an alternate storage pool within the plurality of storage pools from a system-wide deduplication index that indexes each data chunk in each storage pool. In addition, the method creating a new object holding the undamaged copy in the first storage pool, the new object linked to the damaged copy through the system-wide deduplication index.

摘要： Various embodiments are provided for facilitation of data retention using logical objects. Following an operation creating a redundant copy of the data performed on a scheduled interval, a logical object containing a number of managed file versions, represented by a number of member objects for a recovery point, is created. The logical object is assigned a policy of a data retention policy construct associated with the recovery point. The logical object is adapted for reassignment between policies of the data retention policy construct associated with various recovery points. During the reassignment, the plurality of member objects representing the plurality of managed file versions are logically retained instead of performing a data copy operation to associate the plurality of managed file versions with another recovery point.

摘要： Provided are a computer program product, system, and method for restoring a restore set of files from backup objects stored in sequential backup devices. Backup objects are stored in at least one sequential backup device. A client initiates a restore request to restore a restore set of data in a volume as of a restore point-in-time. A determination is made of backup objects stored in at least one sequential backup device including the restore set of data for the restore point-in-time, wherein the determined backup objects are determined from a set of backup objects including a full volume backup and delta backups providing data in the volume at different points-in-time, and wherein extents in different backup objects providing data for blocks in the volume at different points-in-time are not stored contiguously in the sequential backup device. A determination is made of extents stored in the at least one sequential backup device for the determined backup objects. The determined extents are sorted according to an order in which they are stored in the at least one sequential backup device to generate a sort list. The extents are retrieved from the at least one sequential backup device according to the order in the sort list to access the extents sequentially from the sequential backup device in the order in which they were stored. The retrieved extents are returned to the client and the client reconstructs the restore data set from the received extents.

摘要： The present invention provides for a system and method for assuring integrity of deduplicated data objects stored within a storage system. A data object is copied to secondary storage media, and a digital signature such as a checksum is generated of the data object. Then, deduplication is performed upon the data object and the data object is split into chunks. The chunks are combined when the data object is subsequently accessed, and a signature is generated for the reassembled data object. The reassembled data object is provided if the newly generated signature is identical to the originally generated signature, and otherwise a backup copy of the data object is provided from secondary storage media.
