Unifi NanoHD on concrete ceiling - which box to provide?

Ok. That means I would have to set up everything anew with the software. I need to think about that. I only have a netbook and no proper computer. And I would rather not install it on the work laptop. I need to consider something...

The netbook is also sufficient for this. It is important to make a backup of the configuration from time to time and save it externally, e.g., on a NAS or external hard drive. Check if it is possible to make a backup in the APP and possibly restore it to the controller. Whether this exists, no idea? If in doubt, start over.
