【摘要】 运用资源属性量化和备份资源的可靠性的量化指标作为支持数据备份策略的度量依据,采用基于系统中资源故障率用来确定数据备份资源数和备份资源的定位,设计了一个全新数据备份策略。针对地震减灾仿真网格应用系统的需求背景,运用提出的备份策略设计了备份管理系统,从而解决了地震应用领域的数据备份的问题。更多还原

【Abstract】 The paper uses the measure of resource attribute and reliability of resource replica to design data replica policy.Use the quantitative measurement of fault to determine the quantity of replica resources and the location of replica resources.The paper designs a new replica policy.And use the new replica policy to design he replica management system based on the requirement of earthquake disaster alleviation simulation grid system.All these mean solve the data replica problem in earthquake application field.更多还原
