title: How can I clean my react-native project to back it up?
body: <p>I'm developing a mobile app using React-Native, and as I'm the only developer of it, I don't want to use a versioning tool like git, I don't want to host it on the cloud (trust reasons...), and was wondering how can I make backup of my react-native project, in case of an hardware loss.</p>
  
  <p>The obvious way would be to just archive everything, but it weight 2.2GB and about 800mb once compressed. It's ok for one backup, but what if I want to make regular backups?</p>
