Abstract
The present specification discloses a database disaster recovery system, method, and apparatus, a storage medium, and an electronic device. In the database disaster recovery system provided in the present specification, the system includes a first database. A data processing node in the first database synchronizes a log generated for a database operation to at least one data protection node based on a distributed consistency protocol. The data protection node receives and stores the log. In response to some data processing nodes in the first database experiencing an anomaly, a data processing node without an anomaly in the first database provides a database service based on logs stored in the data protection node, thereby implementing disaster recovery for the first database. It can be learned from the above system that, the system can implement disaster recovery without data loss for the first database based on the distributed consistency protocol by using the data protection node independent of the data processing node.
