I’m running ROCK on a NUC with a Seagate USB HDD attached for music storage. I would like to set up automatic backup of the Roon database to the Seagate drive but when I try to create a backup folder on the drive using my Mac running Mojave, I get an error message – I don’t have the necessary permissions. Same problem for trying to copy new music to the drive. I’m probably doing something very basic wrong, but wanted to see if anyone could guide me through this.
