When I create a backup, I get a message that it does not have permission to the docker-data folder. Does anyone know the issue?
Don’t be angry with me - I’m creating a case here for the first time 
du: cannot read directory '/mnt/pi-backup/data/mnt/dietpi_userdata/docker-data/overlay2/0b1997523fecc381fb7f4e34c0a9fdbd893889ff750076aa4da11d0ff77408dc-init/work/work': Permission denied

This is what the permissions on the folder look like.

I use the latest version of Dietpi v8.9.2
Welcome to our community.
In general it is not needed to create screen prints. You should be able to copy everything from SSH terminal directly.
Which user you are using to create the backup?
Thanks for the comment, I will take it to heart ;). I use the dietpi user.
Pls try using root user or use sudo to start the backup
The error pattern does not change
even using the real user root was not working???
Can you share following
ls -la /mnt/pi-backup/data/mnt/dietpi_userdata/docker-data/overlay2/0b1997523fecc381fb7f4e34c0a9fdbd893889ff750076aa4da11d0ff77408dc/work/

I receive the message: access is not possible

Strange that you have permission issues for a directory that doesn’t seems to exist. Can you share following
ls -la /mnt/pi-backup/data/mnt/dietpi_userdata/docker-data/overlay2/
here is the result
ls -la /mnt/pi-backup/data/mnt/dietpi_userdata/docker-data/overlay2/

ahmm the assigned user/group is completely wrong. It should be root:root and not 1004:users. Is /mnt/pi-backup/ an external drive? And did you connect it to a different Linux box?
It is /mnt/pi-backup/ an external NAS drive and the user has RW rights.
as you can see on your own information provided, only user with ID 1004 has r/w access. Have a look to your NAS. There you should see who this user is.

I guess it’s NFS, have a look to the server configuration.
Anyway, current backup has incorrect file perission. I recomment to create complete new one.
