摘要
目的:探索减轻任何不可预知事件对信息系统正常运行灾难性影响的容灾方案,提高数据管理的安全性、可靠性。方法:根据医院信息化建设的实际情况,针对存储镜像、主机镜像、数据库镜像技术等3种容灾技术的原理和特点,进行了分析和比较。结果:基于存储镜像技术的容灾技术,具有可支持各种应用和操作系统、故障恢复机制简单、易于操作、管理方便、性价比合理的特点。结论:根据具体需求,合理地选择一种或综合采用多种容灾技术,这样才能建设成安全、可靠的信息系统容灾体系。
Objective To study the disaster recovery solution for the information system. Mothods Three disaster recovery technologies were analyzed and compared, including storage mirror technology, host mirror technology and database mirror technology. Results The disaster recover solution based on storage mirror technology, compatible with all application and operating systems, was better than the two ones based on the other two technologies in the aspects of operation, management and cost. Conclusion It is suggested that one or several disaster recovery technologies he selected to make the information system safe and reliable.[Chinese Medical Equipment Journal, 2010, 31 （4） ：45-46,49]
