摘要: 采用模块化方法设计并实现一种支持热归档的异地容灾系统(RDTS)。该系统在设备驱动层实现监控,对上层应用程序透明。通过引入热归档,有效解决了病毒感染和用户误操作造成的数据损坏问题以及对容灾系统实时镜像数据进行归档时须停止服务的问题,节省了远程容灾中心的存储空间。实验结果验证了该系统的优越性。

Abstract: This paper presents a Remote Disaster Tolerant System(RDTS) supporting hot archiving under the method of modularization. The system provides the transparency because of being implemented on device driver level. Another important advantage is the inductiveness of hot archiving, through which the data damaged problem caused by the virus and the users’ fault are solved, and also the service halting when archiving the mirror data. And the store space in the remote centre has been saved. The experimental results prove the superiority of the system.

Key words: hot archiving, disaster tolerant, monitor, cache, restoration
