    摘要： One aspect of the present invention includes a configuration of a storage management system that enables the performance of deduplication activities at both the client (source) and at the server (target) locations. The location of deduplication operations can then be optimized based on system conditions or predefined policies. In one embodiment, seamless switching of deduplication activities between the client and the server is enabled by utilizing uniform deduplication process algorithms and accessing the same deduplication index (containing information on the hashed data chunks). Additionally, any data transformations on the chunks are performed subsequent to identification of the data chunks. Accordingly, with use of this storage configuration, the storage system can find and utilize matching chunks generated with either client- or server-side deduplication.

    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： Techniques for adjusting the frequency of data backups and initiating event-driven backups in a storage system are disclosed herein. In one embodiment, a self-adjusting backup frequency, known as a “Change Rate Objective,” is defined to conduct or delay backups for one or more volumes in the storage system on the basis of an associated policy value. The Change Rate Objective may be tied to one or more business or data activity events, such as the amount and type of data changes since a last backup. The storage system may also be tailored to conduct or delay full or incremental backups on the basis of a Change Rate Objective that measures whether a full or incremental or differential backup is more appropriate. Various data or system failures, or data or business events may also be used to adjust the retention periods of continuous data protection (CDP) data and delay a rollup of CDP data.
