航天测控系统中的重要资产数据对航天任务的成败有重要影响，必须建立数据容灾系统以保障关键数据的安全。分析了当前航天测控系统关键资产数据采用的备份方式及容灾的要求，基于Oracle数据库的远程复制功能研究了航天测控系统远程数据容灾技术，设计了航天测控系统远程数据容灾方案，并搭建模拟实验环境对方案进行了实验测试。实验结果表明，容灾方案能够达到第五级的容灾级别，满足可恢复性、可靠性和实时性指标要求，实现对航天测控系统关键资产数据的远程容灾。%The critical asset data of the Space TT&C system plays an important role on the space launching missions. Data disaster recover-y system must be established to protect the safety of critical data. Analyze the current storage methods and disaster recovery requirements of the data,the remote data disaster recovery method is studied based on the remote replication capability of the Oracle database,and the Space TT&C system remote data disaster recovery plan is designed. The experiment results based on the simulated experimental environ-ment show that the plan can reach the fifth level of the disaster recovery level and satisfy the requirements of the following three perform-ance indicators such as recoverability,reliability and real-time,therefore realizing remote disaster recovery of the critical asset data of the Space TT&C system.
