NCP v 1.12.3
When I start the manual backup process in the NCP panel, I get the message that the backup drive is a read-only file system. With my pi user on the system, I have the correct write / read permissions.
The backups worked always well since setting up the system. The backup drive is 4 TB and new (Western Digital), so there should be enough space left.
Any hints what may be the problem?

I have writing permission with pi, but somehow the nc user does not. How to fix this?
