Back ups your application settings in a safe directory (e.g. Dropbox). Syncs your application settings among all your workstations. Restores your configuration on any fresh install in one command line. If you have Dropbox installed and want to use it to save your config files, that's super easy. On macOS, if you want an easy install, you can install Homebrew and initialize it with it. If not running macOS, or you don't like Homebrew, you can use pip. On Ubuntu, pip will install to the current user's home directory rather than system-wide. Because of this, when installing pip on Ubuntu you will need to run pip install with the --system flag as well (on other platforms this is not needed). By only tracking pure configuration files, it keeps the crap out of your freshly new installed workstation (no cache, temporary and locally specific files are transfered). Mackup makes setting up the environment easy and simple, saving time for your family, great ideas, and all the cool stuff you like.
