Method and system for transformation of logical data objects for storage

A system for compressing data, comprising:

• a memory device configured to store a logical object (LO);
• and
• a processor in communication with the memory, the processor configured to:
• divide the logical data object into one or more segments, each segment characterized by respective start and end offsets,
• receive data for storage in the LO, and
• compress the received data, wherein compressing the received data comprises combining a time-based compression technique and a position-based compression technique to compress data in the LO, wherein:
• the time-based compression technique comprises compressing the received data to form compressed data,
• the position-based compression technique comprises dividing the compressed data into at least two portions and interleaving the divided and compressed portions,
• when combining the time-based compression technique and the position-based compression technique, the processor is configured to associate the time-based compression technique with continuous segments of positions in the LO, and
• when associating the time-based compression technique with continuous segments of positions in the LO, the processor is configured to associate distinct time-based compression contexts with the continuous segments of the positions in the LO.
