dbman自动备份失败

现场双机冷备环境，使用主机自动备份，备机自动恢复功能实现主备机数据同步。

主备机数据不一致，主机进行过修改配置操作几天后，备机上的数据都未正常同步，查看dbman.log，存在备份异常的情况，导致主备机数据不一致。

查看iMC/dbman/log目录下存在如下报错：

即为找不到SHM数据库文件信息，经现场确认，在进行dbman备份前，有进行过SHM组件去部署操作，去部署后未通过部署监控代理页面的配置按钮重新触发dbman读取组件信息，导致dbman的配置文件还记录SHM组件数据库信息，在进行备份时因找不到SHM组件数据库从而出现备份失败的情况。

点击部署监控代理页面的配置按钮后点击确定，重新触发dbman读取组件信息后，即可备份成功。
