Embodiment Construction
[0097] The invention discloses a Delta compression storage component based on block-level data deduplication, such as figure 1As shown, the Delta compression storage component includes a container access module; the container access module uses a similar index, a similar buffer and a container buffer data structure to run a container storage algorithm and a container recovery algorithm; the container storage algorithm receives The write container command sent by the upper block-level data deduplication storage system performs Delta compression on the container, and writes the Delta-compressed container into the container storage pool on the disk; the container recovery algorithm receives the block-level data of the upper layer The read container command sent by the deduplication storage system reads the specified container from the container storage pool on the disk through the container index, and returns the read container to the upper block-level data deduplication storage s...
