摘要
目的:建设具有异地容灾功能的高可靠性备份系统架构。方法:引入数据备份的概念,介绍了常用的数据备份方式及其机制,并进行了相应的比较。结果:综合多种备份方式,设计并实现了具有异地容灾功能的高可靠性备份系统架构。结论:安全数据备份系统的建设已成为医院信息化建设不可或缺的重要基础,通过该高可靠性数据备份系统的实现,既能避免硬件单点故障,又能修复数据的逻辑损坏。
Objective To construct a safe data-back-up system with disaster-tolerant ability. Methods Based on the concept of data back -up, the paper puts forward several data back -up modes in common use, and carries out corresponding comparison. Results The author synthesized these back -up modes into an ideal, feasible, and highly secure system architecture with disaster-tolerant ability. Conclusion Constructing a safe data-back-up system are becoming the mostly indispensable elements for the hospital informationization. It can avoid the single fault in the hardware level, and also can repair the logical data fault in the software level.
