Design and Implementation of the Remote Disaster Tolerant System Supporting Multi-Production Center

A disaster tolerant system supporting multi-production center has been presented. It monitors writing requests on device driver level at local servers in real-time, then transmits the data to remote server through Internet and backups it in the database. The system does not need enterprises to build disaster tolerant center by themselves, So, it can help enterprises cut mean at most maximum. Moreover, the system provides a B/S architecture-based system configuration.
