Abstract

The invention discloses an annular two-place three-center topology switching method, device and system and a storage medium, and relates to the technical field of computers. The method is used for a second disaster recovery system, data of the second disaster recovery system is periodically and asynchronously copied by data of a first disaster recovery system, data of the first disaster recovery system is synchronously backed up by data of a production system. The method comprises the following steps of: sending a first detection message to the first disaster recovery system; judging whether a first data transmission link with the first disaster recovery system is normal or not according to the first detection message; if the first data transmission link is abnormal, disabling the first data transmission link, and activating a second data transmission link with a production system; and receiving data sent by the production system based on the second data transmission link. By adopting the method, the problems that the efficiency is low, data leakage is easily caused, and the safety performance is reduced due to the fact that a user needs to manually switch the annular 3DC topological relation can be solved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method, device, system and storage medium for ring-shaped two-site-three-center topology switching. Background technique [0002] Ring 3DC is also called ring two-site three-center, which is a way to support three systems for disaster recovery. The three systems are the production system, the first disaster recovery system and the second disaster recovery system. Generally, the production system and the first disaster recovery system are in the same computer room or in the same city, while the second disaster recovery system is in a different place. Under normal circumstances, the topological relationship is that the production data is directly written into the production system and backed up to the first disaster recovery system through synchronous replication; the data of the first disaster recovery system will be backed up to the second disaster recovery system through pe...
