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 encrypting data objects to back-up to a server. A client private key is intended to be maintained only by the client. A data object of chunks to store at the server is generated. A first portion of the chunks in the data object is encrypted with the client private key and the first portion of the chunks in the data object encrypted with the client private key are sent to the server to store. A second portion of the chunks in the data object not encrypted with the client private key are sent to the server to store.

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.
