提出一种基于Linux平台逻辑卷管理系统的块级别多模式数据客灾模型,论述了其系统结构与工作流程,并详细讨论了快照数据备份、连续数据保护、远程数据复制3种客灾模式的工作原理与关键技术.
A multi-mode data disaster-tolerance model is presented for information systems based on Logical Volume Manager (LVM) on Linux. Its architecture and work flow is introduced at first. Snapshot backup, continuous data protection and remote data replication are three main disaster-tolerance modes in this model, and their principles and key technologies are discussed in detail.
