摘要：
Disclosed is a data replication technique using the hierarchical organization of data servers which is contrived to minimize a burden on a metadata server and also improve the performance of the entire system by operating data servers efficiently. To this end, a data replication method using the hierarchical organization of data servers in accordance with the present invention includes dividing a plurality of data servers into a primary data server group and a secondary data server group and managing, by a metadata server, information on the state of each data server group and metadata.
