Design and implementation of data consistency of remote data replicating system
远程复制系统数据一致性研究与实现

A method was presented to keep data consistency and data view consistency and to optimize system performance in a remote disaster-tolerate data replication system.It used log volume to record the user's acquirement,and maintained data consistency by keeping block update order between primary and backup volumes,and adopted different transport methods according to different data types.The architecture,implementation method and key techniques of the method were discussed.
