1. A computer implemented method, comprising:

  • generating an instruction for uncompressing at least one compressed version of data corresponding to an uncompressed version of data in a version chain containing a plurality of versions of data, the instruction containing a key representative of a location of a data segment to be copied in the uncompressed version of data and a value representative of a length of data segment to be copied in the uncompressed version of data, the data segment is present in at least another uncompressed version of data in the version chain; and

    uncompressing, based on the generated instruction, the at least one compressed version of data;

    wherein the compressed version of data depends on another compressed version of data corresponding to the another uncompressed version of data in the version chain;

    wherein the at least one of the generating and the uncompressing is performed on at least one processor of at least one computing system.
