摘要： Data objects are replicated from a source storage managed by a source server to a target storage managed by a target server. A source list is built of objects at the source server to replicate to the target server. The target server is queried to obtain a target list of objects at the target server. A replication list is built indicating objects on the source list not included on the target list to transfer to the target server. For each object in the replication list, data for the object not already at the target storage is sent to the target server and metadata on the object is sent to the target server to cause the target server to include the metadata in an entry for the object in a target server replication database. An entry for the object is added to a source server replication database.

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.
摘要翻译：公开了以事务一致的方式安全地删除数据的过程。这可以通过在管理数据对象的系统内为数据对象提交准备事务来实现，以便如果需要，将系统返回到初始条件，仅在提交准备事务之后试图提交与数据对象的执行事务，并且如果提交执行事务失败，则安全地删除将系统返回到初始条件所需的数据对象的任何部分，并且只有在提交执行事务成功时才将系统更改为完成条件。在删除或移动事务中，可以为现有的备份对象分配新的逻辑删除状态，以便如果删除或移动事务失败，则数据将被再次访问。

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.
摘要翻译：本发明提供了一种确保存储在存储系统内的重复数据删除的数据对象的完整性的系统和方法。将数据对象复制到辅助存储介质，并且生成诸如校验和的数字签名。然后，对数据对象执行重复数据删除，数据对象被分割成块。当随后访问数据对象时，组合块，并为重新组装的数据对象生成签名。如果新生成的签名与原始生成的签名相同，则提供重组的数据对象，否则从辅助存储介质提供数据对象的备份副本。

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： One aspect of the present invention includes an optimized simultaneous storage operation for data objects onto a combination of deduplicated and non-deduplicated storage pools. In one embodiment, a data object is provided for storage onto destination storage pools in a storage management system, and placed into a source buffer. The data object is first divided into data chunks if the data object has not previously been chunked within the storage management system. The data object is then simultaneously copied from the source buffer to each destination storage pool (deduplicating and non-deduplicating) with the following operation. If the destination pool utilizes deduplication, then the individual data chunks are only transferred if copies of the individual data chunks do not already exist on the destination storage pool. If the destination pool does not utilize deduplication, then all chunks of the data object are transferred to the destination storage pool.

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： 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： 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.
