Proxmox 8.4 and Veeam Backup issue while the VM is offline

[cpns]

We recently converted from VMware and are wondering if anyone else here is having issues backing up offline VMs with Veeam BR?
Do you have a recommendation for a workaround other than powering those VMs manually during the backup schedule?

When the VM is offline, we are seeing nothing.

root@proxmox:/dev/storage1# ls -la | grep vm-114
root@proxmox:/dev/storage1#

When the VM is online, we are seeing the disk.

root@proxmox:/dev/storage1# ls -la | grep vm-114
lrwxrwxrwx 1 root root 8 Apr 27 10:31 vm-114-disk-0 -> ../dm-39
root@ns-pm2:/dev/storage1#

Veeam cannot back up the disk when it cannot see it.

Never had this issue when we were on the VMware hypervisor, but then again, we were not using an "agent" like with Proxmox, so I understand it's not the same.

Thank you, fam.

Update.

Our vSAN StarWind support engineer suggested shutting down the VM with the following command and then running the Veeam backup again.

qm stop 114 --keepactive

Guess what?
It worked. Veeam backed up the offline VM without issue.

Now, my next question is how to make this command the default in Proxmox when I click shutdown in the GUI?

Hi,

This is expected in Proxmox. When a VM is shut down from the GUI, its disk is fully deactivated, so Veeam can’t see it.

Using: qm stop 114 --keepactive

works because it keeps the disk active even when the VM is off.

a way to make --keepactive the default in the GUI. As a workaround, you’ll need to use a script or run this command before your Veeam backup job.
