摘要:
网络数据备份的可测性因素通常是用户在定制备份计划及策略时最为关注的，对其进行有效评估是备份系统在人性化设计和功能上的要求，但也是设计备份系统时所面临的巨大挑战。基于此，通过对网络数据备份的基本流程进行分析，提出一个基于数据量变化率函数的备份代价评估模型，并给出初步的量化公式。实践表明，该模型是基本有效的
Abstract:
The measurable factors of network backup system is the most attentive when the user customizes the backup plans or policies. Evaluating these measurable factors effectively is necessary for the human design and functions of backup system, but it is also tremendous challenge. By analyzing the key procedure of data backup, a model of data backup cost was put forward and the computing formula accordingly was given. At last,an experiment was shown to prove the correctness of the evaluation formula in some environment at least
