Hi,
I want to backup my VMs with vzdump.
The storage for the snapshots is a NAS system, so I mounted it:
Code: 
# mount
/dev/mapper/debian-root on / type ext3 (rw,errors=remount-ro)
tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=0755)
proc on /proc type proc (rw,noexec,nosuid,nodev)
sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)
udev on /dev type tmpfs (rw,mode=0755)
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev)
devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=620)
/dev/sda1 on /boot type ext2 (rw)
//172.8.1.31/server_backups on /mnt/backup type cifs
In the Proxmox WebGUI:
Storage -> Add Directory -> Directory: /mnt/backup and Content: VZDump Backups
New Backup Job, but I get an error:

In the log:
Code: 
 'vzsnap-debian-0' [U]'/dev/debian/root''[/U]  failed with exit code 5
Why /dev/devian/root?
The backup should be on /mnt/backup and this is an external NAS. So I don't need extra space on the host or whatever this exactly means.

I think I misunderstand something, can somebody help me?
