Hi folks,

today I tried to backup one of my VMs with the PVE UI. I tried it several time, but the result is always the same:

Where can I get more informations and how can I fix/resolve it?

No, sadly. Backups of others VMs to the same storage are running fine w/o any error. Only this one fails. Thanks for your reply, dietmar!
 
If you have enough space while the backup is running, what about your LVM on which the VM lies? Is there any error shown in dmesg or messages?
