Hello,
I tried to create a backup of all VM by adding an external USB HDD to the system, mount them at /media/backup. Afterwards I started the backup via GUI. I am able to see that the backup finished (it reached 100%) but afterwards the tmp file failed.
If I look at the directory I am able to see a file of 62GB was created without problems.
For me it does not look like that some file permissions are not correct furthermore disk space should also not be a problem because I use a new 2 TB HDD. I don't have any idea what could be the reason for the issue.
