提出了一个数据备份和恢复的数学模型,并在其基础上设计和实现了基于Windows平台远程逻辑卷容灾系统的原型,重点论述了该系统实现的基本原理、灾难恢复流程以及对应的关键技术设计.实验证明,该数据容灾系统较好地保证了数据一致性和系统可用性.
The paper presents an abstract model of backup and disaster recovery, which contributes to the implementation of a prototype of remote logical volume replication system on Windows. The infrastructure, disaster recovery process and key technology details are focused on. Results of experiment show that the system has been built up with data consistency and availability.
