METHOD AND SYSTEM FOR TRANSFORMATION OF LOGICAL DATA OBJECTS FOR STORAGE

摘要

A method and system for compressing a raw logical data object (201) for storage in a storage device operable with at leastjone storag protocol, creating, reading, writing, optimizatic in and restoring thereof. Compressing the raw logical data object (201) comprises creating in the storage device a compressed log ical data object (203) comprising aheader (204) and' one or more allocated jcompresse sections with predefined size (205-1 - 205-2); i iompressing one or more sequentially obtained chunks of raw data (202- 1- 202-6) corresponding to the raw logical data object (201) thus giving rise to the compressed data chunks (207-1 - 207-6); and sequentially accommodating the processed data chunks into: said compressed sections (205- 1 - 205-2) in accordance with an order said chunks received, wherein said compressed sections serve as atomic elements of compression/decompression operations during inpjut/output transactions on the logical data object.
