摘要
基于对Windows和Linux平台卷管理系统的特性分析,提出一种基于卷复制的数据容灾系统模型,并论述了其系统结构、工作原理以及关键技术。该系统的主要特点是采用模块嵌入技术实现系统与平台的有机结合,同时支持多种复制模式以保证数据的一致性,通过加密、压缩传输以提高数据安全性并降低带宽要求,另外提供灾难恢复机制,保证了主数据系统在遭受灾难的情况下可以方便地迁移和回迁。理论和实验均证明,本数据容灾系统较好地保证了数据可靠性和可用性。
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 module-embedding 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.
