  2. Backup Your Data: Before proceeding, ensure you have a complete backup of your GitLab instance to prevent data loss.

Making and Verifying Backups

Backing up your GitLab instance is crucial to safeguard your data against potential loss due to hardware failures, software issues, or other unforeseen events. The backup process involves saving your repositories, databases, configuration files, and other essential components. Here's a comprehensive guide to backing up your GitLab instance:

1. Backup GitLab Data:

GitLab provides a built-in command-line tool to back up your entire instance, including:

  • Database: Contains user-generated content such as issues, merge requests, comments, permissions, and credentials.
  • Git Repositories: All project repositories, including wikis and design repositories.
  • Attachments: Files uploaded to issues, merge requests, and comments.
  • CI/CD Job Output Logs and Artifacts: Logs and artifacts generated by CI/CD pipelines.
  • LFS Objects: Large File Storage objects.
  • Container Registry Images: Docker images stored in the integrated container registry.
  • GitLab Pages Content: Static websites hosted with GitLab Pages.
  • Packages: Packages stored in GitLab's package registries.
  • Snippets: Code snippets shared within GitLab.
  • Group Wikis: Wikis associated with groups.
  • Project-Level Secure Files: Secure files at the project level.
  • External Merge Request Diffs: Diffs stored externally.

To create a backup, execute the following command:


sudo gitlab-backup create

This command generates a backup archive in the default backup directory, typically /var/opt/gitlab/backups.

2. Backup Configuration Files:

The backup command does not include GitLab's configuration files, which are essential for restoring your instance. Manually back up the following files:

  • /etc/gitlab/gitlab.rb: Contains your GitLab configuration settings.
  • /etc/gitlab/gitlab-secrets.json: Holds your database encryption key and other sensitive information.

To back up these files, copy them to a secure location:


sudo cp /etc/gitlab/gitlab.rb /etc/gitlab/gitlab-secrets.json /path/to/backup/location/

3. Backup Object Storage (If Applicable):

If your GitLab instance uses object storage for items like LFS objects, uploads, or artifacts, ensure that these are backed up separately. The built-in backup command does not include data stored in external object storage. Consult your object storage provider's documentation for backup procedures.

4. Automate Regular Backups:

To maintain up-to-date backups, automate the backup process using cron jobs. For example, to schedule a daily backup at 2 AM, add the following line to the root user's crontab:


0 2 * * * /opt/gitlab/bin/gitlab-backup create CRON=1

The CRON=1 environment variable suppresses progress output, making it suitable for cron jobs.

5. Secure and Verify Backups:

  • Storage: Store backups in a secure, offsite location to protect against data loss due to hardware failures or disasters.
  • Verification: Regularly test your backups by performing restoration on a separate environment to ensure data integrity and the effectiveness of your backup process.

By following these steps, you can ensure that your GitLab instance is backed up comprehensively, allowing for effective restoration in case of data loss or system failure.
