According to this blogpost backups seem to be a thing:
So I started using the integrated solution now (I was using samba backup addon).
I have 2 questions now:
- I am using a network share (smb/cifs). How can I define to create a subfolder for my backup?
- Is zigbee2mqtt properly backed up? In the config folder I have a zigbee2mqtt folder with a .db and configuration file. Is this all I need for a restore?
