Abstract: This paper presents a design of real-time remote replication system based on LVM after discussing the characteristics of all kinds of approaches of the remote replication, which is an asynchronous and on-line remote replication system purely implemented by software in the existed IP network. And the system provides an easy and economic approach for the remote disaster tolerance technology without any expensive hardware.

Key words: remote replication, production site, disaster tolenance site, data consistency, logical volume manager
