Hallo zusammen!

Ich habe gerade auf einem Knoten das Problem, dass die LXCs nicht im Backup gesichert werden, die QEMUs aber schon. Hier die Fehlermeldung:

Scheint ein Rechteproblem zu sein: 'Permission denied'. Aber es kann nicht auf dem NAS sein, welches als Backupziel herhalten muss, da die VMs schließlich ordentlich gesichert werden.

Hier der Log der erfolgreichen VM-Sicherung:
