近年来，计算机网络相关信息产业得到了空前的发展，很多高校已拥有属于自己

In recent years, computer information network industry has been an unprecedented development, many colleges and universities already have networks of their own. With the information and publishing platform, e-mail, collaboration, thorough application campus card services, more and more valuable information into huge amounts of data, the value of data is also increasing. There is a growing emphasis on data security. Therefore, data disaster recovery issue has become a hot issue. For various reasons, people can not predict the occurrence of disasters, so that the lost data. <br>In order to ensure the normal operation of university teaching, research, management and other related activities, the corresponding information systems disaster recovery construction is very important. From a technology point of view, the general construction of disaster recovery system into the host (including diary application and database operations) based on the two schemes, and based on the storage disk array. On the basis of analysis of various related disaster recovery technology, we put forward reasonable prospect embodiment and made a future disaster recovery expectations.

In recent years, the computer network related information industry has been unprecedented development, many colleges and universities have their own network system. And with the information release platform, mail, co-working, campus card and other services in-depth application, more and more valuable information into a large amount of data, the value of data is getting higher and higher. People pay more and more attention to the security of data. Therefore, the problem of data disaster preparedness has become a hot issue. For various reasons, people can't predict the occurrence of disasters, so that data is lost.<br>In order to ensure the normal operation of teaching, scientific research, management and other related activities in colleges and universities, it is very important to carry out disaster-tolerant construction of the corresponding information system. From the technical realization, disaster-tolerant system construction is generally divided into host-based (including application and database operation journal) and storage disk array-based two scenarios. Based on the analysis of various related disaster-tolerant backup technology, a more reasonable implementation plan is put forward and expectations are made for the future disaster-tolerant backup.

In recent years, the information industry related to computer network has developed unprecedentedly. Many universities have their own network system. And with the in-depth application of information publishing platform, e-mail, collaborative office, campus card and other services, more and more valuable information is transformed into massive data, and the value of data is also increasing. People pay more and more attention to data security. Therefore, data disaster recovery has become a hot issue. Due to various reasons, people can not predict the occurrence of various disasters, resulting in the loss of data.<br>In order to ensure the normal operation of teaching, scientific research, management and other related activities in Colleges and universities, it is very important to build disaster tolerance for the corresponding information system. In terms of technical implementation, disaster recovery system construction is generally divided into host based (including application program and database operation journal) and storage disk array based schemes. Based on the analysis of various related disaster recovery backup technologies, a more reasonable implementation scheme is proposed and the prospect of future disaster recovery backup is expected.<br>
