Backup fails

Proxmox 5.2-10 is set up on a NUC6. Three Debian VMs are running. In addition to the built-in HD, I've set up a CIFS share of my NAS as storage. There I would like to store my backups.

Backup on local HD works fine.

Backup on CIFS target fails. Log:
INFO: starting new backup job: vzdump 101 --mailnotification always --quiet 1 --mode snapshot --mailto xxxxxxxxx@gmail.com --compress lzo --storage qnap-nas-cifs
ERROR: Backup of VM 101 failed - unable to create temporary directory '/mnt/pve/qnap-nas-cifs/dump/vzdump-qemu-101-2018_11_15-10_00_02.tmp' at /usr/share/perl5/PVE/VZDump.pm line 825.
INFO: Backup job finished with errors​

Reason seems to be the access rights. The share is mounted. In terminal i can easily make file operations in the root directory of the share. But as soon as I want to create a directory in the subdirectory dump/ following error appears:

"mkdir: cannot create directory ‘xxxxxx’: Permission denied"​

Probably something quite banal - at least for a LINUX professional. :rolleyes:
 
Hi,

It's strange.
On these kind of NAS you can have something like "advanced permissions" or "Windows ACL".
If active, check if you have the right to create folder. (I think you need a Windows PC to edit these rights)
