ct-Backup fehlgeschlagen -- warum?

[whiterabbit]

Hallo.
Wir haben einen Container, von dem leider kein Backup angefertigt werden kann. Die Meldung lautet:

Alle anderen Backups funktionieren problemlos (gleiches Storage).
Das Verzeichnis besitzt diese Rechte:

drwxrwxrwx 3 root root       20480 Aug 16 10:00  dump

Woran kann das liegen?

Können Sie bitte den Folgende posten:

• pveversion -v
• cat /etc/vzdump.com
• cat /etc/pve/storage.cfg
• cat /etc/pve/lxc/114.conf
