Abstract

The invention discloses an intelligent real-time seamless switching two unit standby method. The method is based on a two unit standby system, wherein a major state server and a standby state server are registered through two unit standby protocols and then form the two unit standby system. The method particularly includes the following steps that (1) the standby state server sends a request for entering two unit standby and judges request reply information; (2) the standby state server determines whether standby connection is established or not according to the request reply information; (3) after the standby connection is established, the standby state server waits for receiving a heartbeat request, if the heartbeat request is received, the standby state server sends a heartbeat request reply, waits for standby operation, and backups data sent by the major state server, if the heartbeat request is not received, the standby state server is initiatively switched to the major state server through the two unit standby protocols. The method further includes the working process of the major state server. Intelligence and real-time performance of the system are guaranteed, network oscillation generated in the process of switching the major state server and the standby state server is avoided, and operation of network users can not be affected.

Description

Technical field

[0001] The invention relates to a dual-machine backup method, in particular to a dual-machine backup method with intelligent real-time seamless switching, and belongs to the technical field of computer networks. Background technique

[0002] Modern IT technology believes that the importance of data and operations in a successful system has far surpassed the hardware equipment itself, and there are extremely high requirements for data security and protection in a complete system. At present, the cluster structure of dual machine backup is adopted, and the system has extremely high reliability. Two servers can provide services to the network as a whole and monitor each other. When one server fails, the processes and services running on it can be automatically taken over by the other server to ensure the work of network users Not affected. The existing dual-machine backup system generally has two backup modes: cold and hot. Cold backup needs to stop the service of...
