摘要
目前大多数分布式存储系统采用静态备份机制保证系统的高可靠性,灵活性差,不适合系统规模及用户访问量不断变化的存储系统,因此提出一种基于用户行为分析的动态备份机制,通过分析用户行为获得相关信息来动态改变备份数量及确定备份位置,具有较强的灵活性,适合大规模的分布式存储系统;实现动态备份系统将其应用于已建立的科技信息数据中心,通过实验分析表明,该动态备份机制能提高系统的可靠性。
Most distributed storage systems use a static backup mechanism to ensure system reliability, it is inflexible and not suitable for the storage system the scale and visits of which are changing. Presents a dynamic backup mechanism based on the analysis of user behavior to dynamically change the number of backups and determine the location of backups, it is flexible and suitable for large-scale distributed storage systems. Achieves a dynamic backup system and applies it to data center of technology and information, experiment analysis shows that the dynamic backup mechanism can improve system reliability.
