A remote data disaster tolerance system based on enterprise IT SAN infrastructure is presented.According to the characteristics of SAN infrastructure,enterprise data were classified into static data and dynamic data.This system was designed based on the electronic vaulting theory.The paper presents the remote disaster tolerance of static data by using virtual tape library to run data backup,transfer and restore,combining with the method of changing process control,and it presents the remote disaster tolerance of dynamic data by innovating and improving current standard data asynchronous replicating method.The results show that it improves the replicating efficiency,reduces the MAX bandwidth of data link.and represents the reliability and cost-saving capability of the system.
