摘要
连续数据保护技术是灾难备份与恢复领域近年来出现的新技术。针对安徽省烟草地市级子公司具有相同信息系统拓扑结构的特点,基于连续数据保护技术,设计了一种通用的异地灾难备份技术方案。该方案不仅能提供本地灾备功能,还具备异地灾备功能,且仅使用2M带宽就能实现远程数据复制。灾难发生时,能够保证对任意时间点数据的恢复。技术测试和方案在阜阳的应用实证,表明本方案是可行的。
Continuous data protection which is booming in recent years is a kind of new disaster backup and recovery technologies.Based on the observations to the characteristics of the identical topology structure of branches of Anhui Tobacco Inc,a universal remote disaster backup and recovery system scheme based on CDP is designed.The scheme can not only be used to provide disaster backup for local base,but also can be used to extend disaster backup using remote base,and especially can copy data from production center to remote backup center just using lowcost 2M bps special line.And data modified at any time can be recovered from the CDP device during disaster recovery.Technical tests and scheme’s practical application in Fuyang branch show that the scheme is feasible.
