摘要
设计并实现了一种将实时镜像存储、系统恢复和系统监控集于一体的异地容灾系统。该系统将本地截获的写操作缓存在本地控制中心上,然后发送到远程进行重放完成异地备份。该系统通过访问控制机制解决了在传统灾难备份系统中访问控制薄弱的问题;通过差错控制保证了镜像数据的可靠性;通过密钥管理机制保证了灾备系统自身的安全。
A disaster-tolerant system with the features of real-time mirroring, data recovery and system monitoring was designed and implemented. The system saved write requests into local control center buffer when capturing them; then sended these requests to the remote host and resubmit them tO achieve remote backup, By the access control mechanism, this system solved the problem of access control weakness in traditional backup system, It also ensured the reliability of data with error control and achieves the system＇ s security with key management.
