[Problem]: Container on QNAP NAS: Backitup can't access mount point

[n-albrecht]

Description / Beschreibung

Hi, I have installed iobroker as a docker container on a QNAP NAS. Everything works fine so far, except backups.
I have set up a new user "iobroker" in the NAS and given it permissions to a certain folder (/Container/iobroker).
In portainer, I have mounted the remote folder as an additional volume to the container.
SSHing into the container, I have read/write access to the folder (I've mounted it in the container to /root/backup).
However, Backitup in iobroker does not work, it creates the backup files to /opt/iobroker/backups and when trying to copy that to /root/backup, it says
[ERROR] [cifs] - Path "/root/backup/" not found
I've also tried to mount the NAS folder via CIFS, but here I get

[DEBUG] [mount] - cifs-mount command: "sudo mount -t cifs -o username=iobroker,password=****,rw,uid=iobroker,gid=iobroker,file_mode=0777,dir_mode=0777,vers=2.0 //192.168.178.120/Container/iobroker/backups/ /opt/iobroker/backups"
[DEBUG] [mount] - first mount attempt with smb option failed. try next mount attempt without smb option ...
[DEBUG] [mount] - cifs-mount command: "sudo mount -t cifs -o username=iobroker,password=****,rw,uid=iobroker,gid=iobroker,file_mode=0777,dir_mode=0777 //192.168.178.120/Container/iobroker/backups/ /opt/iobroker/backups"
[ERROR] [mount] - [undefined Error: Command failed: sudo mount -t cifs -o username=iobroker,password=****,rw,uid=iobroker,gid=iobroker,file_mode=0777,dir_mode=0777 //192.168.178.120/Container/iobroker/backups/ /opt/iobroker/backups
Unable to apply new capability set.

Trying to manually mount from within the Container using
mount -t cifs -o username=iobroker,password=[password],rw,uid=iobroker,gid=iobroker,file_mode=0777,dir_mode=0777 //192.168.178.120/Container/iobroker/backups/ /mnt/Container/
also gives me the "Unable to apply new capability set." error

192.168.178.120 is the IP of my NAS. User iobroker is also in a group of that name and has permissions to the /Container
I've restarted the container several times already.
Any ideas?

Also, I found out that this link from the documentation isnot working:

Edited the topic, my bad, apologies

[buanet]

As this seems not to be a issue, I`ll convert this into a discussion.

Regards,
André

Thanks for moving! I thought since I did not experience expected behaviour it is an issue, sorry for the confusion.

This can be closed. Mounting did work after I changed the following:

• In iobroker's Backitup set connection type to cifs, check mount as root and enter the path with a trailing backslash, then the path on the NAS.
• The docker container needs to run in privileged mode
  Sorry for any confusion.
