Design And Implementation Of Data Backup System Of The Martial Information Network

With the development of the technology of computer network, the backup technology has been used widely. The perfect network backup system should be added the software backup which based on the hardware fault tolerance system, and can backup the data of the whole network flat automatically. But in the martial information network which needs advanced data security, the backup technology has not been applied widely at present. The reason is the unattached network backup system has not been established, and can't implement the backup of the appropriative database and fulfill the lash-up recovery requirement of the martial information network under the war environment. So, it is necessary to develop an appropriative data backup system, which has the native and remote backup functions, and can fulfill the lash-up comeback requirement of the martial information network.In this paper, the backup system of the martial information network is designed and implemented. First, we analyzed the data safety technology, which mostly includes the technology of network backup, disk array, cluster and fault tolerance etc. Secondly, we analyzed the requirement of the backup of the martial information network, provided the whole design scheme and design object of the system. Thirdly, we constructed the native backup network, designed the modules of native backup, server cluster management, backup recovery and native backup policy. We also summarized some difficulties which presented in the process of native backup design and gave the solutions. At last, we constructed the remote backup network, designed and implemented the remote backup module and the remote backup monitor module. We analyzed the security of the remote backup data and gave the testing result of remote backup.
