Abstract:
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.
