Hello, Thanks to previous answers, I was able to make backups. Unfortunately, we had some infrastructure issues and after the host reboots new problems appeared. I am not able to do any backup using the commands that worked yesterday. I looked through the logs and there is something like this: 2020-07-17 15:06:30,644+02 ERROR [org.ovirt.engine.core.bll.StartVmBackupCommand] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-54) [944a1447-4ea5-4a1c-b971-0bc612b6e45e] Failed to execute VM backup operation 'StartVmBackup': {}: org.ovirt.engine.core.common.errors.EngineException: EngineException: org.ovirt.engine.core.vdsbroker.vdsbroker.VDSErrorException: VDSGenericException: VDSErrorException: Failed to StartVmBackupVDS, error = Checkpoint Error: {'parent_checkpoint_id': None, 'leaf_checkpoint_id': 'cd078706-84c0-4370-a6ec-654ccd6a21aa', 'vm_id': '116aa6eb-31a1-43db-9b1e-ad6e32fb9260', 'reason': '*Parent checkpoint ID does not match the actual leaf checkpoint*'}, code = 1610 (Failed with error unexpected and code 16)

(these errors are from full backup) Like I said this is very strange because everything was working correctly.
