Thank you for your answer and please excuse long reaction time.
I couldn’t really find out what is wrong here, even after looking through content of the REST API answer.
On this Proxmox VE there’s only 2 VMs.
- ID 100: Windows Server
- ID 101: Proxmox Backup Server (no backup of course, as this is the backup machine)
I had to re-install everything and accidently gave Proxmox Backup Server VM ID 100 and Windows Server VM ID 101.
This cannot be changed after creation, except for cloning the VM and deleting the old one etc.
I suspect the problem is the Backup of ID 100 does not look like it’s a Backup of VM ID 100.
I will keep the backups locally for a while.
After everything seems to be okay, I will delete the backups of VM ID 100 from the local Proxmox Backup Server (we have one in the cloud too, for offsite-backup purposes) and re-activate the Proxmox VE Check again to see if this fixed the problem.
I will post another comment when I have done that.
Thank you for your help and patience.
Best regards,
