Data disaster tocerance backup control system

The invention relates to a control system of data backup and disaster recovery. It includes main control computer connecting with outside network through optical fiber, main control equipment and management terminal. There are three network interfaces in main control equipment. An interface connects with outside network, and the others respectively connect with main and backup information center with a same inside construction configuration. In normal state, outside network interface of main equipment connects with network interface of information center, namely, main information center is running. Data storaged in database is storaged into database of backup information center at the same time. Once failure happens, main control equipment connects with backup information center under controlled by main control computer and backup information starts to run. Service for users will not be broken, which realizes seamless disaster recovery. Switching time is less than 3 seconds and there is no data lost.
