your dif fbackup fails with: [2023-10-24 09:50:08] ERROR root virtnbdbackup - main [MainThread]: No existing checkpoints found, execute full backup first. your full backup failed with:
but no log was provided that suggests wether if the full backup done before was successful for not. Something has failed before or you have an issue with your workflow. Please provide logfile for the FIRST backup placed in /opt/kvm_pool/HDD/ During the first full backup the backup should have created a file /opt/kvm_pool/HDD/<vm_name>.cpt in your case: 0231024-082035620420084-158_test-backup.cpt where it stores the list of checkpoints. During the diff backup, no checkpoints are found:
and thats pretty strange. Please make sure you use one folder per backup set and placethe backups virtnbdbackup -d 20231024-082035620420084-158_test-backup -l full -o /opt/kvm_pool/HDD/weekly-vm1 If you create a new full backup, rotate folders: virtnbdbackup -d 20231024-082035620420084-158_test-backup -l full -o /opt/kvm_pool/HDD/monthly-vm1 |

The Virtual machine was offline during first Backup! Full Backup that is required as base for further backups Must be taken if vm is online and running, bcs only then libvirt can create Checkpoints! setOfflineArguments [MainThread]: Domain is offline, resetting backup options. Please ensure vm is running while taking Full backup |
