Hi Community,
First time I am trying to restore a VM from the backup, and I am getting the following error. About a year ago, I switched from RHEL KVM to Proxmox VE and also installed Proxmox Backup on a mini PC with 1 TB of storage and integrated it with Proxmox VE. Promox is still to me; I am not sure if I missed something during installation, configuration, or integration. How can I restore the VM, and how can I fix the issue so it won't happen again? Appreciate your help.
