Abstract: Online data replication is the basic part of disaster-tolerate system. This paper discusses the system architecture and the module architecture of the FreeBSD platform data Replication System(FRS), and presents how these modules cooperate. It designs and implements a FRS which embeds general replication device driver layer. The system has a strong independence, flexibility and versatility, and can achieve replication on data block level while maintain independent on specific storage devices and logical volume manager.
