摘要
Abstract
Traditional space mission systems face problems such as multi-generation coexistence,in-flexible deployment,incomplete disaster recovery methods,and slow emergency switching speed,making it difficult to adapt to the integrated management and control mode under cloud architecture.It is necessary to solve the problems of disaster recovery system design and system-level migration and switching.The security risks and characteristics of space mission systems are analyzed in this ar-ticle.A remote disaster recovery backup system under a cloud architecture is designed,and solutions such as virtualization migration,network layer control transformation,application layer domain name transformation,and communication configuration integration management are proposed.Addition-ally,a migration deployment process and a method for building a fast switching chain are formed.Ex-periments have shown that,compared with traditional backup methods,remote disaster recovery backup systems under cloud architecture can shorten the system-level deployment and switching time to 3 hours,which significantly improves the ability to respond to anomalies.This can provide technical support for the construction of disaster recovery backup systems and special scenario appli-cations under the integrated control mode in the future.关键词
