Warning after the backup is completed.

[Michal6040]

Hello, I can't figure out why, after completing the backup on the Proxmox Backup Server, the backup finishes with a warning. I'm not sure if I'm misreading the log or if there really isn't any stated reason for the warning.

Thank you in advance for your help.

That warning is referring to line 3898 of the log you attached:

WARN: no efidisk configured! Using temporary efivars disk.

This appears to be referring to VM 159, which is expecting an EFI disk but finds none. This warning will presumably show whenever you start VM 159, which is what the backup procedure is doing.

Hi,

there is this warning in the log:

INFO: VM Name: zy-v-win02
INFO: include disk 'scsi0' 'HDD01:vm-159-disk-2' 100G
INFO: include disk 'scsi1' 'HDD01:vm-159-disk-3' 100G
INFO: creating Proxmox Backup Server archive 'vm/159/2025-02-21T02:49:16Z'
INFO: starting kvm to execute backup task
WARN: no efidisk configured! Using temporary efivars disk.

In short, this means your VM 159 (zy-v-win02) is configured to use UEFI/OVMF, but does not have a EFI disk configured, which is used to store EFI configuration data.
You can create one under the Hardware tab, by clicking on Add > EFI Disk.
