Systems and methods for compressing a raw logical data object () for storage in a storage device operable with at least one storage protocol, creating, reading, writing, optimizatic in and restoring thereof. Compressing the raw logical data object () comprises creating in the storage device a compressed logical data object () comprising a header () and one or more allocated compressed sections with predefined size (---); compressing one or more sequentially obtained chunks of raw data (---) corresponding to the raw logical data object () thus giving rise to the compressed data chunks (---); and sequentially accommodating the processed data chunks into: said compressed sections (---) in accordance with an order said chunks received, wherein said compressed sections serve as atomic elements of compression/decompression operations during input/output transactions on the logical data object.

Systems and methods for transformation of logical data objects for storage

Methods and systems for compressing a logical data object for storage in a storage device in a distributed network are provided. One method includes creating, in the storage device, a compressed logical data object including a header and one or more allocated compressed sections with a predefined size, compressing the one or more obtained chunks of data corresponding to the logical data object, thus giving rise to the compressed data chunks, and storing the compressed data chunks in the compressed sections, wherein the compressed sections serve as atomic elements of compression or decompression operations during input/output transactions on the logical data object.

Systems and methods for transforming a logical data object for storage in a storage device operable with at least one storage protocol, creating, reading, writing, optimization and restoring thereof. Transforming the logical data object comprises creating in the storage device a transformed logical data object comprising one or more allocated storage sections with a predefined size; transforming one or more sequentially obtained chunks of obtained data corresponding to the transforming logical data object; and sequentially storing the processed data chunks into said storage sections in accordance with a receive order of said chunks, wherein said storage sections serve as atomic elements of transformation/de-transformation operations during input/output transactions on the logical data object. The processing may comprise two or more data transformation techniques coordinated in time, concurrently executing autonomous sets of instructions, and provided in a manner preserving the sequence of processing and storing the processed data chunks.

Systems and methods 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.

Systems and methods for transforming a logical data object for storage in a storage device operable with at least one storage protocol, creating, reading, writing, optimization and restoring thereof. Transforming the logical data object comprises creating in the storage device a transformed logical data object comprising and one or more allocated storage sections with a predefined size; processing one or more sequentially obtained chunks corresponding to the transforming logical data object, wherein at least one of said processed data chunks comprises transformed data resulting from said processing; sequentially storing the processed data chunks into said storage sections in accordance with an order the chunks received. The method further includes reading a data range from the transformed logical object in response to a read request specifying desired point in time to be read.

A method and system for transforming a logical data object for storage in a storage device operable with at least one storage protocol, creating, reading, writing, optimization and restoring thereof. Transforming the logical data object comprises creating in the storage device a transformed logical data object comprising a header and one or more allocated accommodation sections with predefined size; processing one or more sequentially obtained chunks corresponding to the transforming logical data object thus giving rise to the processed data chunks, wherein at least one of said processed data chunks comprises transformed data resulting from said processing; sequentially accommodating the processed data chunks into said accommodation sections in accordance with an order the chunks received, and generating at least one index section constituting a part of the transformed logical data object, said index section comprising one or more entries containing indicators to physical storage location of respective accommodation sections and, with respect to each processed data chunk, one or more records related to said chunk, wherein said records indicate offset and length of data in the logical data object to be read from the respective processed data chunk, and are associated with a time stamp indicating time of creating said record. The method further facilitates reading a data range from the transformed logical object in response to a read request specifying desired point in time to be read.
