A disaster-tolerant system with the features of real-time mirroring,data recovery and system monitoring was designed and implemented.The system saved write requests into local control center buffer when capturing them;then sended these requests to the remote host and resubmit them to achieve remote backup.By the access control mechanism,this system solved the problem of access control weakness in traditional backup system.It also ensured the reliability of data with error control and achieves the system's security with key management.
