[0034] figure 1 Shown is the overall flow chart of the present invention. First, divide the network where the disaster recovery system needs to be deployed into several logical areas according to the network scale, geographical location, and disaster recovery intensity. For example, if a nationwide disaster recovery system is deployed, it can be divided into logical regions such as Northeast, North China, East China, South China, Northwest China, and Southwest China.
[0035] After that, disaster recovery servers need to be deployed. The disaster recovery server is a network node with relatively good software and hardware performance. It can be selected from existing nodes in the network, or a new node can be added to the network. There must be at least one disaster recovery server in a logical area. The disaster recovery server must manually install the disaster recovery server software and database software in advance.
[0036] The database software is responsible for reco...
