Scheduler doesn't run

Post by inanotherlife »

Hi,
I'm using Cobian Reflector 0.9.56 on Windows Server 2019 Essentials in a Hyper-V virtual machine. Reflector never runs when the task is scheduled, nor does it log any error whatsoever.
I'm not sure but the only non-traditional thing I'm doing is backup of the virtual machine with Windows Backup from the host. Before starting the backup, the host Hyper-V pauses the machine, saving the state. After finishing the backup, the virtual machine is started again (without restarting the guest OS in the whole process). Maybe this is something that breaks the scheduler of Reflector, because if I schedule it for about 10 minutes from now, it DOES start.

Perhaps... I really don't have any idea about how Hyper-V handles an awakening.

Me too, but everything other than Reflector is OK.
What is the scheduling mechanism of Reflector? How could I check if it is scheduled or not and how it works?

It's just a thread checking for the actual time and comparing it with the task list. Nothing fancy.

OK, so is there anything I could do?

I will need to install a Hyper-V machine to test.

I have now tested on a Hyper-V machine with a task as a timer. Have tested pausing the machine , waiting some minutes, starting again... and the schedule keeps working. Both as a service and as a application.

I'm using Windows Server 2019 on both, host and guest. The virtual machine is saving the state when Windows backup from host starts full backup. It resumes when finishes.
I've configured monthly backup on 1st and 15th. Please check the attached pictures.
I hope this is of some use for the case.

No problems. After the pause and the resume, the schedule starts again.
