Design And Implement Base On Hospital Disater-tolerated System Of Remote Mirroring

In recent years, the large centralized data has become a major focus of my government, enterprise information construction trends. Along with the large centralized data on the achievement of enterprise-class data center technical risk is relatively concentrated. Once the data center disaster to occur,would lead to all branches, business outlets and all of the processing standstill,or cause the loss of customer data,the consequences would be unthinkable. Because of a variety of data may be lost,along with people's increasing reliance on network systems,from hardware to software for data protection and backup is the link should not be overlooked. If the user operational systems in place a comprehensive disaster backup/recovery incident response system, when sudden disaster,the key business data systems business losses will be kept to the minimum .Remote morroring namely remote replicate, it is the pivotal technology of backup for disater,it is also the foundation which keep synchronization and carry out disater recovery, it is the primary task how to combine the appropriate technology of backup for disater into integrated disater emergency response system.In this paper includes the following parts:①Introduce the significance of backup for disater emergency response and the conception concerned backup for disater;②Import incident response methodology and analyse every phases of PDCERF and Introduce the technology concerned backup for disater emergency response;③Lucubrate remote mirroring technology which is the key technology of backup or disater, analyse and compare the principle of work,capability,apply area of synchronization and asynchronization of remote mirroring data replicate mode. and thereout bring forward the object and idea which found remote mirroring system;④Base on incident response methodology,link the characteristic of backup for disater emergency response,bring forward backup for disater emergency response methodology, and analyse every phases of backup for disater emergency response flow;⑤Research the remote mirroring technology material application in HIS backup for disater emergency response base on HIS framework and requirement of backup for disater;⑥Summarize some production which recent procure in policy and technology, analyse the relation of backup for disater and emergency response and apply in future, moreover prospect the work in future.Disater recovery is the last line of defence which enterprise ensure business continuity when disater break out,it is also the last phase of emergency recovery, we must attach importance to disater emergency recovery.
