摘　　要：分布式的信息资源管理系统必须保证其可靠性,而可靠与高效又相互矛盾。利用冗余技术设计了一个高可靠性的系统模型。模型采用写时复制方式做检查点,并选择了最佳的检查点间隔,从而提高了应用程序的执行效率。实验结果表明:该冗余系统简单、高效、可靠。Distributed management system of information resource must be reliable,but it is conflicting between reliability and efficiency. A reliable system model is designed with redundant technology.For the sake of improving efficiency of application,the model adopt Copy-on-Write to set checkpoint,and select the best interval of checkpoint.Experimental results show that the model is simple and efficient and reliable.

关 键 词：信息资源管理 冗余 可靠 高效
