Abstract: A method of efficiently replicating data stored in data servers in an asymmetric file system is provided. A replication processing apparatus of a network transmits a replication request only to a data server that does not replicate data so that it is possible to reduce replication time of a data block and to extend time-out with reference to a response message transmitted by the data server. In addition, each of the data servers may efficiently transmit copy data to another data server by a pipeline data transmission method.

Abstract: In order to synchronize a file between transmitting and receiving nodes, when a file is changed, a hint provider of the transmitting node provides a change file and change information about the change file as a hint to a change log generator, the change log generator generates a change log with reference to the change file and the hint, and the generated change log is transmitted to the receiving node by a change log transmitter.
