Hospital Data Disaster Recovery System

Disaster recovery system (DRS) will respond to automatically and restart the application on the redundant equipment to keep the business continuing, while the disaster of data take place. Basically the disaster can't be predicted, and the loss that it results in also can't be precision estimated, but it is fatal for the hospital if the disaster occurs. Hospital data disaster recovery is a part of the project of the hospital continuity. And the key of the project is to build hospital data disaster recovery system (HDDRS).This paper imitated the case that the hospital disaster will occurrence, and estimate the information (such as the data, the trades, network and so of the hospital) of hospital information system (HIS). Based on the requirement principle of building HDDRS, it analyzes the result of comparison and integrates some case studies of redundancy technology.This paper gives some experience the redundant mechanism for HIS. Considering the construction condition and the definition of disaster recovery level, it deals with the rule of building HDDRS.
