The present invention discloses a data replication method using the layering of a data server for improving the performance of a whole system by efficiently operating the data servers while minimizing the burden at a meta data server. Therefore, the data replication method using the layering of the data server is characterized in separating the multiple servers into a first data server group and a second data server group and managing the status information and meta data of each data server group by the meta data server.
