Hi

I tried to backup an LXC via suspend (via snapshot is working fine):
I created a new directory /root/temp and added this to /etc/vzdump.conf.

The backup fails with this output:
Code:

Can someone point me how to fix the permission denied? I have created the temp via root user login.

drwxr-xr-x 2 root root 4096 Feb 3 10:00 temp

Thx in advance!
