摘要 提出并实现一种远程文件备份与恢复系统(FBRS),利用FBRS客户端将须备份的文件进行系统快照,判断该文件是否有更新,并进行差异计算,将差异计算结果(即差异文件)发送到FBRS服务器,在FBRS服务器端进行差异重放,实现远程文件同步。测试结果表明,FBRS同rsync相比,能显著减小网络带宽的消耗。 A remote File Backup and Recover System（FBRS） is presented and realized. Through adding a system snapshot for the backup file on FBRS client, it determines whether the file is updated, computes the difference and sends the result of difference compute（difference file） to the FBRS server, the FBRS server playback the difference file, the remote file synchronization is realized. Test results show that compared to rsync, the system can prominent reduce the network bandwidth consumption.
