摘要: 为避免数据备份系统建设的盲目性,要在建设前期,根据系统工作特点,对存储容量、备份窗口、读写能力等关键参数进行研究分析。从最简单、理想的系统构建出发建立数学模型,通过实例进行量化分析。考虑网络、操作系统、机械设备、不可预计因素等对备份过程的影响,在模型中加入修正参数,估算出和实际需求相吻合的参数值,服务于系统构建和策略优化。

关键词: 数据备份, 参数, 估计, 优化

Abstract: To avoid the blindness of data backup system construction, this paper researches the key parameters of storage capacity, backup window, read and write performance, etc, depending on system running characteristic before putting it into execution. From the simple and perfect system architecture, it builds the mathematical models, analyses quantitatively by instances, and takes enough account of the effects of network, operating system, mechanical devices, accidents, etc, adds the proper repair parameter depending on the actual cases, and tries to estimate the practical parameters to serve system design and strategy optimization.

Key words: data backup, parameter, estimation, optimization
