After building my first addon I wanted to also back it up. As it does not contain stratic data and purely relys on the UI configuration of the addon I thought it is just some bytes more. But after the backup it was 700MB more as it exported the built image and included it into the backup.
Maybe the question is stupid but how to exclude the image from the backup? I checked the developers documentation but did not really find an answer. Am I doing something wrong? Repos is https://github.com/ruepp-jenkins/hassio-addons
