PURPOSE: An efficient data recovering method in a distributed file system is provided to efficiently reduce recovery task time by configuring data servers as a pipeline. CONSTITUTION: If a first data server is detected through a metadata server, location information of data servers is detected for storing recovery data of the first data server(S200). A recovery task requests recovery data to the data servers(S300). If a recovery task of the data server is completed through recovery operation, the recovery completion of the data server is reported to the metadata server(S400). |
