A disaster recover system replica management scheme based on cluster servers is introduced in this paper,in which a consistency maintenance algorithm of multiple replicas and a replica selection algorithm are put forward and a mathematical model of quantity and distribution of replicas is set up.Fast auto recovery of data,efficient copy management and a balance dependability of replicas and performance of cluster server can be achieved by this system scheme,which is proven by performance test of the disaster recover system.
