Hi all.
I need some help with the below errors as we have tried taking it up with Veritas, but to no avail. On Windows Server 2016, using Veritas Backup Exec, the backup will run once after restarting the guest VM's, and restarting the Hyper-V Management Service on the host. After that the scheduled backups fail.
We ran the "vssadmin list writers" command with the following results:
C:\Windows\system32>vssadmin list writers

This is a huge issue for us as the backups have to be started manually after restarting the guest VM's and restarting the Hyper-V Management Service on the host.
Any assistance would be appreciated.
