Remote data replication is the key technology in the disaster-tolerance system.It plays a important part in implementing disaster recovery.Considering generality and expansibility,this paper presents a data-replicator system based on windows operation system.Its architecture and work flow are described in this paper.As well as ensureg primary data view consistency and secondary data consistency,we design and implement parallel IO strategy to improve the efficiency of the Primary and request combination strategy to reduce bandwidth during transmitting datas.The experimental analyses show that the two strategys are effective and efficient.
