It's important that you have your source code secured so that when your laptop breaks down—or even worse, the office got destroyed—the most valuable part of your company (besides the employees, of course) is still intact. You've already taken an important step into the right direction; you set up a Git server so that your source code has multiple places to live. However, what if that server breaks down?
This is where backups come into play! GitLab Omnibus makes it really easy to create backups. With just a simple command, everything in your system gets backed up: the repositories as well as the databases. It's all packed in a tar ball, so you can store it elsewhere, for example, Amazon S3 or just another server somewhere else.
In this recipe, we not only created a backup, but also created a schema to automatically back up the creation using crontabs. This way, you can rest assured that all of your code gets backed up every night.
