GitLab Group Backup

Creates full backups of a GitLab group including its subgroups and all projects via the GitLab API.

  • Separate backup archives for group metadata and projects
  • One backup file per repository, allowing selective restoring via the GitLab web interface or API
  • Repositories are stores as git bundles, allowing to restore data independent of GitLab.
  • Handles rate-limiting of GitLab API
  • Supports private groups
  • Works with personal and group access tokens
  • Can automatically be run as recurring task via Docker

Usage

Usage example: ./main.py --gitlab-url=https://gitlab.com --access-token=0123456789ABCDEF --group-id=42

usage: main.py [-h] [-s] [-o OUTPUT_DIR] -u GITLAB_URL -g GROUP_ID -t ACCESS_TOKEN

options:
  -h, --help            show this help message and exit
  -s, --create-subdir   Create a new subdirectory, named by backup date,
                        inside output directory for each backup
  -o OUTPUT_DIR, --output-dir OUTPUT_DIR
                        Directory to write GitLab exports into
  -u GITLAB_URL, --gitlab-url GITLAB_URL
                        URL of the GitLab instance to access
  -g GROUP_ID, --group-id GROUP_ID
                        ID of the root group to backup. Multiple group IDs can
                        be passed by repeating this argument.
  -t ACCESS_TOKEN, --access-token ACCESS_TOKEN
                        GitLab API access token

Requirements

All software dependencies are managed via poetry. It must therefore be installed on the system. This project heavily relies on the python-gitlab project, check them out :)

Installation

To install all software dependencies run poetry install inside the project root directory.

Configuration

This tool is primarily configured by CLI arguments (see: ./main.py -h). The config.yaml file contains additional configuration parameters and can be used to overwrite any of the CLI arguments.

API Access Token

A personal access token or group access token with the following permissions is required:

  • Scopes: api, read_api, read_repository
  • Role: Owner (applies to group access tokens only)

The token is supplied via the --access-token CLI option or via the config.yaml file.

Group ID

The ID of a GitLab group can be found on the group main page directly below the title. It is supplied via the --group-id CLI option or via the config.yaml file.

Running via Docker

A docker-compose.yaml file is provided. To run this tool using Docker, conduct the following steps:

  1. Copy .env.dist to .env and add your configuration details
  2. Build the image: docker compose build
  3. Run a container: docker compose run gitlab-group-backup

Exports are written into the /data folder inside the container. It is mapped to the host folder ./data by default.

Notes

  • Request rate limiting is automatically applied. A strongly enforced rate limit can greatly impact the execution time of this script.
  • The Owner role and api scope are required to trigger the creation of backups within GitLab.
