【摘要】To improve the construction of disaster recovery system constantly and enhance the ability of the disaster recovery backup systems , analyzing on the disaster recovery evaluation indexes of the backup systems for disaster recovery is necessary. The existing information system disaster recovery capability evaluation index system is established according to the national standard 20988-2007 GB/T, and has the problem of low efficiency of evaluation. Firstly a new disaster recovery backup system ability index of fine-grained classification is proposed according to the latest disaster recovery center construction and operation management specification of national standard GB/T 30285-2013. using the AHP analytic hierarchy process. Secondly multi-index system is simplified by applying system clustering method with improved incomplete information indexes in statistical principle. Thirdly the backup experience system is built, after which the ability of disaster recovery system is evaluated respectively using two sets of index system. At last, by using fuzzy comprehensive evaluation method, the new evaluation index system can reduce the experts’ time to verify the weight of evaluation index, and improve the efficiency of disaster
