Scheduled job no longer runs

[Hajah]

Hi,

I've a scheduled job that runs daily @ 3h30am with Veeam B&R v8 for VMWare.
This scheduled backup job used to work flawlessly since it was created. This last week, it stops because of Backup Window, with nothing done.
Backup window is 3am till 6am. The daily backup job takes ~45 minutes. Most of the time it finished before 4h30am.

The thing is that NOTHING is done. Not even 1 VM. Also it doesn't stop at 6am. It stops at 12h30 (9hours before it started).
The first task reports this:
-Queued for processing at 2/26/2016 3:37:16 AM
-Required backup infrastructure resources have been assigned
-Error: Job was stopped due to backup window setting
-Network traffic verification detected no corrupted blocks
-Processing finished with errors at 2/26/2016 12:37:33 PM

The following tasks (VMs) don't even start, because of backup window.

Then if I start it manually, all is well. No issues at all.

Where can I look to debug this? I'm assuming something is not "available" at 3h30am when the schedule starts the backup, and when I start it manually @ 2pm, all the resources are there and no errors occur (except for the slowdown on the production VMs).

Thanks for your help!

What are the backup window settings in this job, how it is configured?

Hi,

Terminate job if it exceeds allowed backup window
Backup window:

Monday: 3h00am to 5h59am
...
Friday: 3h00am to 5h59am

Thanks for looking into this.

Looks unexpected, I'd contact support for verification.

I once saw something similar after the time zone was changed on a backup server. A reboot of the server fixed the problem.
