Abstract:

To improve the disaster recovery capability and security assurance level of Yangtze River Hydrological Data Center, and to provide technical support for the continuity of hydrological monitoring and integrated management services, the backup and disaster recovery system for Yangtze River Hydrological Data Center was constructed. This study established a classification and hierarchical management system for hydrological data. Based on differences in data types and levels of business criticality, differentiated backup strategies were formulated. A multi-level disaster recovery protection mechanism was constructed for key business data, forming a full-process and intelligent data backup and recovery system. Practical application results showed that the proposed system effectively improved the disaster recovery response efficiency and fault recovery capability of the Yangtze River Hydrological Data Center, significantly reduced the risk of data loss, and ensured the continuous and stable operation of core hydrological services, providing a reliable technical safeguard for hydrological safety management in the Yangtze River Basin.
