Auto Disaster Recovery System Of Computer

Along with the development of the ages, people have more highly request in risk defensive of the disaster. At the IT realm, the concept and category about disaster is very extensive, its main contents includes natural disaster of a fire, flood disaster, earthquake...etc. however ,network have a big area paralyze, the data of local business database and the backup database destroys in the meantime is also a disaster for the trouble. When some affairs take place, how many data that throw to lose have to be from the instauration data in the backup? Is the data value that throws to lose much big? When the system stop and need to recover a data, how to change the stop system steadily to run status? All of these is worthy of research about the disaster realm. It is the key of the system construction at build up an efficiently of the disaster system.When a large computer system face the disaster occurrence, make use of to permit the disaster technique to carry out the data protection, take over system to go to the district of another safety to continue on-line work, can raise system biggest safety, this kind of way has already got a high value in the industry. But the system takes over to involve various ways, for example server system, storage system, database system, network system etc. Among them, it is the most decisive to determine the level of the disaster system. That is to say, disaster system is according to which level to carry, for example according to operation system, storage system, and file system etc. The article has a deep analysis in definition, function and design about disaster with the enterprise environment. This is a hot topic in IT field. The article introduces a few solution of the disaster recovery from different level. Its main contents are as follows:1. Analyze a disaster recovery system how to guarantee business and data completely. Analyzing seven level of the disaster system according to the idea recovered from the disaster.2. Pointed out the factor of the safety and the function aspect in the disaster system design; put forward how to design the superior disaster recovery system.3. Described the typical technique of the disaster system in detail, discussed the way to build up a disaster according to the three different realizations of server, cluster and storage.4. Pointed out the idea of disaster tolerant according to analysis of TianJin social insurance management information system. Analyzing that system in detail is to how make use of HAGEO (the high availability geographic cluster) technique to carry out to viable disaster recovery.
