This paper proposed a new survivable cloud storage service model, and designed the structure of the model and constructed in detail. Then adopted a storage service survivability evaluation method (resource allocation failure probabihty model) based on probability models to analyze the service model. The fully evaluation justifies that the cloud storage service model can satisfy survivability.%提出了一种基于云存储的可生存存储服务模型,对模型架构进行了详细设计和构造,并采用了一种存储服务模型可用性的度量方法(资源分配失效概率模型)进行了分析.通过分析可得,提出的可生存云存储服务模型能够满足较高的可生存性的需要.
