摘要
对于任何一个系统,数据的安全性是保证系统正常运行的重要因素。结合实际工作需要,对水利电子政务系统数据库应急恢复方法进行研究,分析数据备份的重要性和恢复测试的必要性,比较了物理和逻辑备份恢复方法的优缺点,通过具体实例,对Oracle数据库的备份和恢复的方法进行归纳总结,希望对双机集群数据库的备份和灾难恢复有一定参考价值。
For any system, data security is an important factor to ensure normal system operation. Combined with practical work, this paper makes a research on methods of emergency response database recovery for water resources E-government by analyzing importance of data backup and necessity for test recovery, and making comparison of advantages and disadvantages between physical backup and logical backup. Finally, methods of oracle database backup and recovery are summarized hoping that it can provide some value for reference in two-clustered database backup and disaster recovery.
