A brief discussion on where the project data generated by GitLab is stored

GitLab is an excellent code hosting platform that allows developers to create projects, manage code and collaborate on it. This platform is simple to use and powerful, which can greatly improve development efficiency. However, many GitLab users are not clear about where project data is saved. Next, let’s talk about where the project data generated by GitLab is stored.

First of all, we need to understand where the several parts of the project data are saved. GitLab project data is divided into the following parts:

1. Git warehouse data: including source code, commit history, etc.
2. Database data: including user information, project information, setting information, etc.
3. File data: including pictures, documents, logs and other files.

GitLab uses different methods to save these data. Let’s look at them separately below.

1. Git warehouse data

Git warehouse data is one of the most important data in GitLab. It includes source code and related information submitted by developers. In GitLab, each project has a Git repository, and the data in the Git repository will be saved in the GitLab server. Specifically, after GitLab is run, the corresponding Git repository is saved to /var/opt/gitlab/git-data/repositories in the GitLab installation directory. In this directory, each project has a corresponding directory, which stores all the code and submission history of the project. If you want to back up Git warehouse data, you can directly back up the directory of the corresponding project.

2. Database data

GitLab's database data includes user information, project information, setting information, etc. The storage location of these data is different from the Git warehouse data. After GitLab runs, these data will be saved to the /var/opt/gitlab/postgresql/data directory under the GitLab installation directory. Specifically, all PostgreSQL database data is stored in this directory. If you want to back up GitLab database data, you can directly back up the entire directory.

3. File data

In addition to basic data such as code, GitLab also has various file data, such as pictures, documents, etc. This data is usually not saved in a Git repository, but is uploaded through GitLab and saved to the server's file system. After GitLab is run, these file data will be saved to the /var/opt/gitlab/gitlab-rails/uploads directory under the GitLab installation directory. In this directory, each project has a corresponding directory, which stores all the files uploaded by the project. If you want to back up the file data uploaded by GitLab, you can directly back up the directory of the corresponding project.

To sum up, the project data generated by GitLab includes Git warehouse data, database data and file data. They are stored in /var/opt/gitlab/git-data/repositories, /var/opt/gitlab/postgresql/data and /var/opt/gitlab/gitlab-rails/uploads respectively in the GitLab installation directory. If you want to back up GitLab project data, you need to back up the above three directories.

In short, data security is very important in GitLab, so it is very important to back up GitLab project data. Hope this article can be helpful to you.
