摘　　要：针对军用业务系统的高容灾需求,提出一种自适应多点容灾模型,实现了应用和数据的自适应多点容灾,能够容忍并发或连续多重军事打击。该模型扩充了常用的容灾目标,根据用户需求自动生成应用和数据的多点部署方案,应用容灾能力评估技术动态评价和调整容灾方案,基于虚拟化技术执行应用部署、动态资源分配、备份管理和切换管理,构造分层的多点数据备份和恢复。原型系统在模拟环境中验证了该多层结构的有效性。A new self-adapted multipoint disaster tolerance model which meets the high requirements of defending multiple continuous disasters for military information systems is proposed. This model extends the normal measures of disaster tolerance, produces the deployment scheme automatically from the user＇s requirement and uses the disaster-tolerance ability evaluation technique to evaluate and adjust the disaster tolerance plan. It also uses the visualization technology to deploy, backup, failover and failback applications, and constructs layered nodes to backup and restore data. The prototype has verified the efficiency of the model in the simulation environment.
