Research and Design of Data Disaster Tolerant System on Multi-platform
多平台数据容灾系统的研究与设计

Based on the volume management system for Windows and Linux,a data disaster tolerant system is proposed,and its architecture,implement principle and key technologies are discussed.This system has three technical characters: first,adopting the moduleembedding technology to integrate the system into the platforms;secondary,supplying users with three replication models of Sync,Async,and Soft-Sync,encrypting data to improve the security and compressing data to meet the bandwidth of networks;third,using disaster recovery mechanism to guarantee that the primary data system in disaster can be solved with disaster-over and disaster-back.It's proved that this system increases reliability and availability of data highly.
