With the deepening of Internet applications, computer-based Communication systems promote that the enterprises and institutions work efficiency and economic efficiency. As the core data of Communication systems in various fields occupies an important position, it is important resources to the survival of enterprises and institutions. However, in the actual work, there are many factors cause paralysis of the computer network system resulting in data loss, such as the operation of human error, the damage to the computer hardware and software, virus invasion, hacker attacks, natural disasters and so on. Because more and more valuable critical information change into the data, if there is not timely and effective data backup and recovery, the loss will be immeasurable for the majority of enterprises and institutions, and may even be devastating. Therefore, the establishment of a network data backup program can achieve offsite backup data to better protect data, and minimize the disaster loss.Based on the traditional data backup solution and the development of the backup system technology in recent years, the paper had done an explore and study on the data backup technology; In the beginning, it starts from the background of the research topic, research status, as well as the subject research. It researched a lot of different parts in the network data backup system, such as the concept of backup, backup strategy, and backup storage technology. At the same time, introduces the mainstream backup techniques, including the file-based backup and the block-based backup, and has carried on the comparative analysis of two kinds of technique; Aiming at the existing problem of the file-level backup, this paper put forward improvement methods; Basis on the analysis of backup technology and the improvement level-file backup, the paper introduces the main function of this article file-level backup system; Then was the analysis and design of network data backup system as a whole, system is mainly based on the TCP/IP protocol make computers to communicate with each other in the network, and to achieve the purpose of file data transfer, the technology of network data transfer involved in the backup process is described in this paper, then is the design and implementation of the backup client and the backup server, also did an analysis of the results of the backup systems; Finally, the paper gave a summary of the full text and an outlook of the future.
