安全的灾难备份系统

摘要

针对传统灾难备份系统安全性不高的问题,提出一种安全的灾难备份系统,使用差错校验、安全传输和加密存储,保障了备份数据在传输、存储过程中的安全性.在完全同步完成后,通过卷过滤驱动实时监控磁盘数据变化,采用高速缓存存储捕获到的数据,并通过网络发送到远程备份中心.该方法实现了数据的高效、实时、异地备份,同时兼顾了安全性和高效性.%To resolve the problem of poor security in the traditional disaster recovery systems, a safe disaster recovery system is proposed. Error checking, secure transmission and storage encryption are adopted to ensure the security of backup data in transmission and storage. After the completion of the fully synchronization, the disaster recovery system monitors the local data' s changes by volume filter driver. Then high-speed buffer is deployed to store the data captured which is going to be sent to the remote backup center over the network. This method achieves the effective, real-time, remote data backup, with the features of security and high efficiency.
