Research And Design Of The System Of Two-level Remote Disaster Recovery And Backup (DRB) Based On Agent

With the rapid development of network technology, more and more dependent on computer storage for the data services and decision support. The information technology sector to bring the ease of management at the same time, there are some potential risks. Once the data loss, the relevant units will bring about enormous losses. Therefore, the disaster recovery backup system building more and more attention from all departments, related technology and research is also rapid development.In this paper, firstly,from popular of the current domestic and international disaster-related technology based on technical analysis, summarized the application of technologies suitable for the area, with an emphasis on data synchronization technology were discussed. At the same time, according to research needs in-depth study of the Agent-related technology and theory, analyzed and summarized the current Agent major application areas and trends.Secondly, the existing disaster recovery technology in the discussions on the basis of a combination of demand and the actual project construction objectives by the two-level architecture based on the System of Remote Disaster Recovery, The design program.Thirdly, the focus on disaster recovery system for remote data synchronization subsystems in-depth study, according to the system's data synchronization requirements, a remote agent-based technology to achieve data synchronization database model, effectively enhance its versatility.The last part of thesis points out the program referred to some shortcomings, disaster recovery and data synchronization technology and related technology to the future development trend of the future.
