It would be nice to have a Backup/Restore module in KStars that could be used to backup all KStars/INDI settings, Add-on's(images/catalogs), profiles, astrometry.net files, darks, etc.
If you are using it on a raspberry pi, I made something like what you are describing in a script. If you used my AstroPi3 script to set up the raspberry pi, then in the utilities folder there is a script that does it.
The reason for this was because people often switch back and forth between raspberry pis and copy them and make backups. It is nice to be able to back up the settings and transfer them.
