Method, system and program storage device for providing a backup of data of a memory to at least one storage medium

A program storage device readable by a computing device, tangibly embodying a program of instructions, executable by the computing device to perform a method for providing a backup of data of a memory portion to at least one storage medium having a plurality of segments, the method comprising:

• partitioning the memory into a plurality of memory blocks of data;
• compressing the data in a first block to produce a first compressed data associated with the first memory block;
• writing the first associated compressed data to a first associated segment of the storage medium;
• and
• synchronizing the steps of compressing and writing to allow compressing a second block of data to produce a second associated compressed data while writing the first associated compressed data to effect pipelined compressing and writing of blocks of data.

A system for providing a backup of data comprising:

• a memory partitioned into a plurality of memory blocks of data;
• at least one storage medium having a plurality of segments;
• mapping means for associating each of the plurality of memory blocks with one of the plurality of segments;
• at least one compressor compressing the data in a first block to produce a first compressed data associated with the first memory block;
• at least one writer associated with the compressor to define a compressor and writer pair for writing the first associated compressed data to a first associated segment of the storage medium;
• wherein the compressor and the writer are synchronized to allow the compressor to compress a second block of data to produce a second associated compressed data while the writer writes the first associated compressed data to effect pipelined compressing and writing of blocks of data.

A method of providing a backup of data of a memory portion with at least one compressor and writer pair to at least one storage medium having a plurality of segments, the method comprising:

• partitioning the memory portion into a number of memory blocks;
• the compressor compressing data, block by block, to produce compressed data for each block;
• and
• the writer writing the compressed data for each block to an associated segment of the storage medium;
• wherein the compressing and writing are synchronized and occur in a pipelined manner with the compressor being able to compress data of a next block without having to wait for the completion of writing of compressed data of an earlier block to the storage medium.
