摘要
提出了一种基于逻辑卷的连续数据保护系统的设计方案,论述了它的系统结构以及实现方法。该系统不依赖于具体的存储设备,能实现数据块级的连续保护,并可以实现保护时间区间内任意时间点的恢复。系统提供了独特的数据存储组织结构和相应的空间管理策略,并且具有很好的恢复技术。该系统提供了一种经济、通用的纯软件方案,能广泛推广应用。
This paper presents a continuous data protection system design based on logical volume,and elucidates its structure and method. The system does not depend on the specific storage devices,it can achieve the continuous blocklevel data protection and can restore data to any time point. The system provides a unique organizational structure of data and the corresponding management strategy,and has a good recovery efficiency. The system provides an economic, cornmon softwareonly programmes,to promote wider application.
