Code Quality Linux/Mac OS X Windows

gitbackup is a tool to backup your git repositories from GitHub (including GitHub enterprise) or GitLab (including custom GitLab installations).

gitbackup only creates a backup of the repository and does not currently support issues, pull requests or other data associated with a git repository. This may or may not be in the future scope of this tool.

If you are following along my Linux Journal article (published in 2017), please obtain the version of the source tagged with lj-0.1.

Binary releases are available from the Releases page. Please download the binary corresponding to your OS and architecture and copy the binary somewhere in your $PATH. It is recommended to rename the binary to gitbackup or gitbackup.exe (on Windows).

gitbackup requires a GitHub API access token for backing up GitHub repositories and GitLab personal access token for GitLab. You can supply the token to gitbackup using GITHUB_TOKEN and GITLAB_TOKEN environment variables respectively.

• repo: Reading repositories, including private repositories
• user - read:user: Reading the authenticated user details. This is only needed for retrieving your username when cloning via HTTPS and retrieving private repositories.

• api: Grants complete read/write access to the API, including all groups and projects. For some reason, read_user and read_repository is not sufficient.

When you provide the tokens via environment variables, they remain accessible in your shell history and via the processes' environment for the lifetime of the process. By default, SSH authentication is used to clone your repositories. If use-https-clone is specified, private repositories are cloned via https basic auth and the token provided will be stored in the repositories' .git/config.

Typing -help will display the command line options that gitbackup recognizes:

$ gitbackup -help

  -gitlab.projectMembershipType string
        Project type to clone (all, owner, member) (default "all")
  -gitlab.projectVisibility string
        Visibility level of Projects to clone (internal, public, private) (default "internal")
  -ignore-private
    	Ignore private repositories/projects

  -use-https-clone
    	Use HTTPS for cloning instead of SSH

To backup all your GitHub repositories to the default backup directory ($HOME/.gitbackup/):

$ GITHUB_TOKEN=secret$token gitbackup -service github

To backup only the GitHub repositories which you are the "owner" of:

$ GITHUB_TOKEN=secret$token gitbackup -service github -github.repoType owner

To backup only the GitHub repositories which you are the "member" of:

$ GITHUB_TOKEN=secret$token gitbackup -service github -github.repoType member

To backup all projects you either own or are a member of which have their visibility set to "internal" on https://gitlab.com to the default backup directory ($HOME/.gitbackup/):

$ GITLAB_TOKEN=secret$token gitbackup -service gitlab

To backup only the GitLab projects (either you are an owner or member of) which are "public"

$ GITLAB_TOKEN=secret$token gitbackup -service gitlab -gitlab.projectVisibility public

To backup only the private repositories (either you are an owner or member of):

$ GITLAB_TOKEN=secret$token gitbackup -service gitlab -gitlab.projectVisibility private

To backup public repositories which you are an owner of:

$ GITLAB_TOKEN=secret$token gitbackup \
    -service gitlab \
    -gitlab.projectVisibility public \
    -gitlab.projectMembershipType owner

To backup public repositories which you are an member of:

$ GITLAB_TOKEN=secret$token gitbackup \
    -service gitlab \
    -gitlab.projectVisibility public \
    -gitlab.projectMembershipType member

To specify a custom GitHub enterprise or GitLab location, specify the service as well as the the githost.url flag, like so

$ GITLAB_TOKEN=secret$token gitbackup -service gitlab -githost.url https://git.yourhost.com

To specify a custom backup directory, we can use the backupdir flag:

$ GITHUB_TOKEN=secret$token gitbackup -service github -backupdir /data/

This will create a github.com directory in /data and backup all your repositories there instead. Similarly, it will create a gitlab.com directory, if you are backing up repositories from gitlab. If you have specified a Git Host URL, it will create a directory structure data/host-url/.

If you have Golang 1.12.x+ installed, you can clone the repository and:

$ go build

The built binary will be gitbackup.
