摘要： A method of providing a backup of data of a memory portion, by at least one compressor and writer pair, to at least one storage medium having a plurality of segments is disclosed. The method includes partitioning the memory portion into a number of memory blocks. The compressor compresses data, block by block, to produce compressed data for each block. The writer writes the compressed data for each block to an associated segment of the storage medium. Compressing and writing are synchronized to occur in a pipelined manner so that the compressor is 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. A program storage device and a system for providing the above method are also disclosed.
