Beginne damit, das manuelle VM-Backup mit aktiviertem NAS-Backup-Plugin unter Ubuntu 22.04/NFS zu reproduzieren, und untersuche anschließend die Logs des Plugins, des Hypervisors und von NFS rund um den Fehler 530. Als erledigt gilt die Aufgabe, wenn das Backup erfolgreich abgeschlossen wird und die UI nicht mehr „Failed to create VM backup“ meldet.
