Abstract

A disaster recovery switching method, a node and a system are provided. The method is applied to a disaster recovery switching system. The disaster recovery switching system includes a production node, a disaster recovery node and a recording node. The production node currently runs a first production service. The method includes the steps that the recording node receives first recovery information sent by the production node, wherein the first recovery information refers to the information required for recovering the first production service to a latest running state of the first production service; and the recording node sends second recovery information to the disaster recovery node when it is determined that the first production service is recovered on the disaster recovery node, wherein the second recovery information refers to the information required for recovering the first production service on the disaster recovery node obtained according to the first recovery information tomake the disaster recovery node switch the first production service to the disaster recovery node according to the second recovery information. The disaster recovery switching method, the node and thesystem can achieve the seamlessly switching of business, ensure the normal operation of the business, improve the stability of the production service and effectively avoid data loss in the event of asudden disaster on the production node.
