Standby system is the one of policies applied to increase dependability of distributed systems. It can obtain higher dependability by increasing redundancy resource, and still maintain normal functions when distributed systems failures occur.
冗余备份系统是提高分布式系统可信赖性最常采用的策略之一,其通过增加冗余资源的方法来换取更高的可信赖性,使系统在出现故障的时候仍能维持正常功能。

The influence of the protected system on maintenance decision for standby system is analyzed.
由于备用系统长期处于非工作状态,所以其故障具有隐蔽性,本文针对隐蔽故障是否具有延迟性的特点,分别提出了不等间隔的使用检查和功能检测策略。
