摘　　要：设计并实现了一种Oracle数据库远程备份与恢复系统,系统基于C/S架构。客户端部署在生产服务器上,将备份数据传输到远程灾备服务器上实现远程备份功能。通过从灾备服务器上下载备份数据,在生产服务器上恢复,实现数据恢复。通过分段备份和提前传输到备份完成前,改进了数据备份过程中的传输机制。实验证明,本系统实现了Oracle备份与恢复核心功能,同时,提高了传输效率和节约了远程备份总时间。This paper designs and implements a kind of Oracle database＇ s remote backup and recovery system which based on C/S architecture. The client deployed on production server transmits backup data to remote backup server so data backup is implemented. By downloading backup data from backup server and recovering on production server data recovery is also implemented. The transmission mechanism of data backup process is improved by segmented backup and putting transmission ahead of completion of data backup. Experiments indicate this system implements core functions such as backup and recovery. Meanwhile, the transfer efficiency increases and the total time of remote backup reduces.
