I use Git as a backup storage system and the Windows Subsystem for Linux (WSL 1) as my Linux distribution. The Git LFS feature lets me use Git as a backup system for files over 100 MB. Here is how to install the LFS feature in a Git repository.
curl -s https://packagecloud.io/install/repositories/github/git-lfs/script.deb.sh | sudo bash
sudo apt-get install git-lfs
cd some-git-repository/
git lfs install
git lfs track "some-massive-files-name.ext"
