Hi,

Using pbs 2.4.3, i've mounted a qnap samba share to /mnt/mybackups, added my pbs to pve and tried a backup, but everytime i'm getting same error;

Code:
INFO: starting new backup job: vzdump 105 --remove 0 --storage bck_deneme --mode snapshot --notes-template '{{guestname}}' --node fsc
INFO: Starting Backup of VM 105 (qemu)
INFO: Backup started at 2023-08-17 21:40:13

INFO: Backup job finished with errors
TASK ERROR: job errors

i don't think it's a permission issue because when i try;
Code:
sudo -u backup touch /mnt/mybackups/test.txt

it's creating the test.txt in the qnap share, when i check the shared folder when backup started it creates vm/105/owner file and it returns upper error after it.

I didn't receive any error message while i'm adding this share as datastore to pbs.

What could be the problem?
