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 system to synchronize a database and a non-database resource includes an application to transmit a request to a service provider to perform an action. The service provider receives the request and performs the action, the action not being under commit coordination. The service provider further inserts an entry into an action-reversal table to reverse the action and makes the insertion permanent. The service provider, on behalf of the application, then deletes the entry from the action-reversal table. The application may then be configured to perform one of the following: (1) make the delete permanent by performing a COMMIT; and (2) roll back the delete by performing a ROLLBACK. At a later time, the service provider may reverse the action in the event the entry remains in the action-reversal table. Corresponding methods and articles of manufacture (i.e., computer-readable media) are also disclosed herein.

摘要： Methods, computer systems, and computer program products for replicating data are provided. Meta-data and data associated with the meta-data are received at a first data server. A new portion of the data that is not already stored on the first data server is identified. The new portion of the data is stored on a second data server before the meta-data is stored on the second data server.

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.

摘要翻译： 在对数据对象进行重复数据删除的多个传递中的每一个中，开始事务。 如果先前设置了对象的偏移量，则检索偏移量; 否则，偏移被设置为引用对象的开头。 偏移量开始的对象的一部分被重复数据删除，直到满足事务结束标准为止。 交易结束，以执行重复数据删除; 其中对象尚未完全重复数据删除，偏移量刚刚移动已经发生重复数据删除。 对象在每次通过期间被锁定; 其他进程在每次传递期间都无法访问对象，但可以在通过之间访问对象。 每个通行证相对较短，因此对象无法访问的时间长度相对较短。 相比之下，在单个通过内重复数据删除对象会阻止其他进程访问该对象较长时间。

摘要： Data storage services are provided for clients for backup of data objects from the clients. A data object is sent to a first location in a first storage device. A determination is made if the data object was successfully stored at the first location, and if so, meta data corresponding with the data object is stored, wherein the meta data includes first path information on a first data path of the data object to the first location. The data object is migrated from the first location to a second location in a second storage device. A determination is made if the data object was successfully stored at the second location, and if so, second path information on a second data path of the data object is added to the second location to the meta data corresponding with the data object, to update the meta data.
