Image backup schedule

Hello everyone,

I have 6 clients, all running Windows Server. Two of them automatically back up their images every day. However, on the other 4, the backup doesn’t start even when it’s scheduled. That’s why I have to start them manually. I checked the client settings, and the settings for the two that are working and the other four are exactly the same. The backup schedule is set to 1-7/0-24 on all of them. What could be causing this issue? Does anyone have any suggestions for a solution?

Thanks in advance
