METHOD AND APPARATUS FOR REPLICATION OF FILES AND FILE SYSTEMS USING A DEDUPLICATION KEY SPACE

摘要

A method and apparatus for rapid replication of deduplicated file system data is described. The method may include initiating replication of a file from a source deduplication system to a destination deduplication system, and transferring deduplication metadata for each block of the file from the source deduplication system to the destination deduplication system. The method may also include transferring an identifier file from the source deduplication system to the destination deduplication system that includes a block number corresponding to a block of the file and a unique identifier value generated from the block of the file. The method may also include receiving a data request file from the destination deduplication system, and transferring the blocks of data identified in the data request file to complete replication of the file on the destination deduplication system.
