摘要:

为提高灾难恢复能力评估的科学性与准确性,结合灾难恢复国家标准,提出基于资源的灾难恢复能力指标体系。针对灾难恢复能力指标度量缺乏系统研究的问题,依据指标特性,设计基于阈值逻辑树影响分析、网络性能影响分析及基于威布尔分析的动态指标度量方法。该指标体系及其度量在评估中的应用结果表明,其通过逐级细化国标并引入考察影 响因素的4类动态指标,能有效提高国标可操作性及评估的精度。

Abstract:

To improve scientific and accuracy of disaster recovery capability evaluation, combined with disaster recovery GB, this paper proposes the resource-based disaster recovery capability index system. At the same time, for the lack of systematic research on disaster recovery capability index measurement, according to the index properties, it puts forward dynamic index measurements of threshold logic tree impact analysis based, network performance impact analysis based, and Weibull analysis based. It analyzes the application of the proposed index system and its measurement in the evaluation. The results show that the index system and its measurement specify GB layer by layer and introduce four types of dynamic index to monitor the changes in the influencing factors, therefore, to improve operability of GB and accuracy of evaluation effectively.

Key words: disaster recovery capability, disaster recovery resource, index system, dynamic index, measurement, Recovery Point Objective(RPO), Recovery Time Objective(RTO)
