Yes, your translation engine works really well! I shall apologize for his limited information. What he wants to know is in the container DirSyncPro , when Remote Type is set as "local", there should be a mountpoint to "/mnt/local", and he doesn't know what this is and where it should be. I think he may not read the info above the option. I'll help him with the problem in Chinese.
@NAS123 local 模式需要配合插件 “Unassigned Devices Plugin” 使用。你需要使用该插件挂载一个未被挂载进入阵列池的存储设备，然后在 DirSyncPro 的容器安装界面中，手动增加一个挂载的目录，将上述的存储设备的地址挂载到 “/mnt/local” 目录中。
另外，按照你的理解，这个挂载到 /mnt/local 的目录应该是用于备份的目的地目录。
