摘要
容灾系统的基础是实现数据在线复制。论述FreeBSD平台数据复制系统(FRS)的结构,给出其模块设计和模块间的协作关系。设计并实现一种FRS,其中嵌入了通用复制设备驱动层。该系统不依赖具体的存储设备或逻辑卷管理器,具有很强的独立性、灵活性和通用性,能实现数据块级别的复制。
Online data replication is the basic part of disaster-tolerate system.This paper discusses the system architecture and the module architecture of the FreeBSD platform data Replication System(FRS),and presents how these modules cooperate.It designs and implements a FRS which embeds general replication device driver layer.The system has a strong independence,flexibility and versatility,and can achieve replication on data block level while maintain independent on specific storage devices and logical volume manager.
