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： 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： An assembly mating first and second tubular bodies is disclosed. The mating assembly includes at least a sleeve structure forming a part of the first tubular body and defining an inner receptacle surface region, a compression loading assembly integrally formed with, constituted by, or otherwise securable to the second tubular body and at least partially received in the sleeve structure, and a cured adhesive bond positioned between an exterior surface region of the compression loading assembly and the inner receptacle surface region to couple the sleeve structure to the compression loading assembly. The compression loading assembly is laterally expandable at at least the exterior surface region thereof and constructed and arranged relative to the cured adhesive bond so that expansion of the exterior surface region compressively loads the cured adhesive bond in a substantially lateral direction. The strength of the adhesive bond is thereby increased against shear stresses acting on said mating assembly due to longitudinal and/or torsional loading.

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： One aspect of the present invention includes enabling data chunks to be shared among different storage pools within a storage management system, according the use of deduplication and storage information kept at the system level, and applied with policy-based rules that define the scope of deduplication. In one embodiment, the parameters of performing deduplication are defined within the policy, particularly which of the plurality of storage pools allow deduplication to which other pools. Accordingly, a data object may be linked to deduplicated data chunks existent within other storage pools, and the transfer of a data object may occur by simply creating references to existing data chunks in other pools provided the policy allows the pool to reference chunks in these other pools. Additionally, a group of storage pools may be defined within the policy to perform a common set of deduplication activities across all pools within the group.

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.
