    摘要： For use in a storage network comprising a plurality of network elements and operable with a block mode access storage protocol, a method of operating a compression system operatively coupled to at least one computer and to one or more storage devices configured as at least one storage logical unit accommodating data compressed by the compression system, the computer, the storage devices and the compression system are configured as separate network elements. According to the method, the compression system is configured to hold a virtual logical unit, the virtual logical unit is configured to virtually represent in non-compressed form the compressed data stored in the at least one storage logical unit. The size of the virtual logical unit corresponds to an estimated size of raw data which, being compressed, would substantially amount to a size of the storage logical unit. The method includes intercepting one or more data access-related requests from the at least one computer addressed to said storage logical unit, addressing the requests to the virtual logical unit, and facilitating mapping between the compressed data and their virtual representation at the virtual logical unit.

    摘要： A computer program product is used with a programmable device to provide a data item reconstruction element for reconstructing information stored on a back-up information storage subsystem associated with at least one protected volume. The back-up information storage subsystem includes a plurality of storage media, each associated with one of a plurality of sets, the information associated with the protected volume being stored on storage media associated with one of the sets. The data item reconstruction element during the reconstruction operation retrieves in parallel information from a plurality of the storage media associated with the one of the sets on which information associated with the at least one protected volume is stored, to obtain the information which is associated with the protected volume.

    摘要： A method and system for encrypting a plaintext logical data object for storage in a storage device operable with at least one storage protocol, creating, reading, writing, optimization and restoring thereof. Encrypting the plaintext logical data object comprises creating in the storage device an encrypted logical data object comprising a header and one or more allocated encrypted sections with predefined size; encrypting one or more sequentially obtained chunks of plaintext data corresponding to the plaintext logical data object thus giving rise to the encrypted data chunks; and sequentially accommodating the processed data chunks into said encrypted sections in accordance with an order said chunks received, wherein said encrypted sections serve as atomic elements of encryption/decryption operations during input/output transactions on the logical data object.
