The Best GitLab Backup Options and Tools for Your Repository

Backup&DR 101, Git Backup

What will you do if you accidentally lose access to your GitLab repository? Or some of your issues, pull requests, webhooks, or other metadata are gone forever?

You may think that if you keep all your data in Git and use GitLab, which is one of the most secure Git hosting services, everything will be fine. However, losing access to your GitLab repository is a very real possibility and can be disastrous, especially since a GitLab instance contains critical data essential for your software development and organizational workflows.

Keep in mind that Git isn’t a backup in and of itself, and GitLab just like any other service provider is governed by the Shared Responsibility Model, which means that your data is entirely your responsibility. The service provider is only responsible for their service being ongoing and their data being secured.

In this article, we’ll look at different methods and tools you can use to back up GitLab, as well as their pros and cons.
