基于量化评估模型的容灾数据复制产品选择

Selection of disaster tolerance data backup based on quantitative evaluation model

容灾数据复制产品对于信息系统容灾的最终效果具有重要影响,目前业界尚无量化的评估模型可供参考。在建设异地容灾系统的过程中,上海容灾中心探索性地建立了容灾数据复制产品评估模型,并依据该模型对主流容灾数据复制产品进行了测试和评估。容灾系统的成功运行,验证了该评估模型的适用性。

Reasonable evaluation of disaster tolerance data replication products has an important impact on information system disaster tolerance. At present, there is no practical model for reference in the industry. In the process of building remote disaster recovery system, China National Tobacco Corporation for the ?rst time established an evaluating model of disaster tolerance data replication products, and evaluated current mainstream disaster tolerance data replication products according. The successful operation of disaster recovery system veri?ed this evaluation model.
