Restored data doesn't match checksum

[Rocky]

Hi there,

I just tried to restore a machine from a backup and the following error occurred:
Restored data doesn't match checksum

Otherwise the backups could always be restored without errors.

I also tried a backup of another VM, this resulted in the same error, when creating a backup, Proxmox does not give an error and runs successfully.
