## How To Back Up Entire GitHub Organisation Repos

1. Install Dependencies: `sudo pip install pygithub3`
2. Clone this repo using `$ git clone https://github.com/clockfort/GitHub-Backup.git`
3. Just open the cloned repo folder and run the terminal:

```bash
./github-backup.py [Your GitHub Username] [Path To Saving Directory] -o [For Organisation]
```

Example:

```bash
./github-backup.py mohamed786 /home/mohamed786/githubbak -o LineageOS
```

## Use a a personal access token (PAT) instead of your password

You can generate a dedicated personal access token instead of using your GitHub password.

Follow the steps described [here in the GitHub documentation](https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token) and use the token instead of your password.
Using a PAT can also work around issues when two factor authentication (TFA) is enabled on your account.


## Why This Software Exists

This software is useful in many cases:

  - GitHub suddenly explodes.
  - GitHub goes out of business.
  - Your corporation's backup policies are more stringent than GitHub's.
  - You have spotty/no internet access - perhaps you'd like to have all of your repositories available to code on while you ride the train?
  - You are paranoid tinfoil-hat wearer who needs to back up everything in triplicate on a variety of outdated tape media.
