Abstract: Remote data replication is the key technology in the remote disaster-tolerance system.It plays a critical part in keeping the data consistency between the local site and the remote site and implementing disaster recovery.The design and implementation of remote asynchronous data replicaton system based on storage devices level are presented at the basis of deeply study on remote data replication.This system does not occupy the host resources and is transparent to the upper level file system and applications.Moreover,it can reduce the complexity of the upper level software design.
