A full backup of Kodi's data files should do the job, but if you wanted to keep the size down, open the ES File Explorer application and expand the LOCAL menu. Click on the Home link. Expand the TOOLS menu below that now and turn on Show Hidden Files. Now navigate to (click on each folder name listed
Android/Data/org.xbmc.kodi (com.semperpax.spmc for DBMC/SPMC) /files/.kodi/userdata .
From that location, I'd backup the database folder (to a USB device or memory card) and then click on the addon_data folder. I think it is the script.tvguidetecbox folder you'll now find that needs to be backed up.
To double check it works, you could install iVue in Kodi on a phone/tablet/PC/Mac , NOT configure it, close Kodi down. Then "restore" the backup you made above, and see if the set up is transferred OK. If it does, you should be reasonably confident that your backup is functioning and will work on your DroidBOX (without having to actually wipe your DroidBOX's Kodi install first!).
