• B.disaster recovery system usually refers to the remote place in the distance, the establishment of two or more sets of the same IT systems, each other can be health status monitoring and function switching, when a system due to accidents (such as fires, earthquakes Etc.) to stop working, the entire application can be switched to another location, making the system function can continue to work properly.
