Disaster allowable system and method based on cluster backup

Abstract

The invention relates to a disaster tolerance system and a disaster tolerance method based on the cluster backup; the disaster tolerance system includes a load agent unit and a load service unit; the load service unit includes at least two server nodes; wherein, a server node is the main server node which has service interaction with the user terminal; the other servers are non-main server nodes; the service interaction includes that when the main server node writes data to the local database of the main server node, the main server node backups the data in the local databases of the non-main server nodes in the load service unit; the load agent unit includes load schedulers which are respectively connected with the server nodes; when the main server node is detected to be breakdown, the main server node is executed with failure transferring operation; one server node of the non-main server nodes is selected as the main server node to have service interaction with the user terminal. The disaster tolerance system and the disaster tolerance method improve the utilization rate of the single server node and the whole utilization rate of the multiple peer server nodes.

Description

Disaster recovery system and method based on cluster backup technical field The invention belongs to the field of network systems, in particular to a disaster recovery system and method based on cluster backup in the network system. Background technique With the rapid development of modern network technology and the increasing number of users, the scale of the network is getting larger and larger. Therefore, for the servers in the network, both the stand-alone capacity and the number of servers must be simultaneously increased to meet user needs. At the same time, the requirements for the reliability and disaster recovery capability of servers are getting higher and higher. In order to have a reliable disaster recovery mechanism after the disaster that causes the server to be paralyzed, and to do its best to restore the service response to users under the existing conditions, redundant backup of server data must be carried out. Since the stand-alone operation is far from...

However, whether this method based on an independent redundant backup mechanism is dual-machine redundant backup or multi-machine redundant backup, an independent standby machine is required to back up the main machine. When the main machine works normally, the standby machine It is silent most of the time, and only performs detection and backup operations when performing signal detection and data update. Whether it is one-to-one, one-to-many, or many-to-many backup methods, the machine redundancy is very large, and the sta
