Overview of Data Synchronization and Fault Recovery Technology in Multi Active Data Center

The new generation power grid dispatching control system with the architecture of “physical distribution and unified logic” operates through the combination of end operation. It is deployed in the analysis and decision center of the cloud server to ensure the reliability of the analysis and decision-making function through multi-activity. The data synchronization and fault recovery technology of the multi-activity data center is the key core technology to ensure the operation of the dispatching system. This paper analyzes and summarizes the technical status and trend of data synchronization and fault recovery in multi-active data centers by researchers at home and abroad. This paper focuses on data synchronization technology based on different data change capture methods, and data fault recovery technology based on local data center and multi-local data center compares and analyzes the advantages and disadvantages of various technologies, and discusses the development trend of data consistency technology, which provides a reference for further research on data synchronization and fault recovery technology.
