Github Backup

Based on the work of Richard Bairwell.

This script offers two methods to save your Github repositories:

• An advanced method with Node.js (Linux/MacOS/Windows).
• A simple sh script designed to run on the Synology DS range of file storage servers to backup all repositories (and wikis) for a user from Github (Linux/MacOS/WSL).

Bonus in sh version:

• You can auto-push your backup to a Gitea server

With Docker

# node.js version
docker run --rm -v '/mnt/x/backups':/mnt/backups --env GITHUB_BACKUP_PATH=/mnt/backups --env GITHUB_BACKUP_USER=[company] --env GITHUB_BACKUP_TOKEN=[YOUR TOKEN] ghcr.io/creadigme/github-backup:0.1.0

# bin/sh version
docker run --rm -v '/mnt/x/backups':/mnt/backups --env GITHUB_BACKUP_PATH=/mnt/backups --env GITHUB_BACKUP_USER=[company] --env GITHUB_BACKUP_TOKEN=[YOUR TOKEN] ghcr.io/creadigme/github-backup-sh:0.1.0

Prerequist

• Ensure you have git installed on the Server/Synology.

Note: on DSM Synology - this can be download from the SynoCommunity.

• Now login to Github and go to Fine-grained personal access tokens and create a fine-grained token with the following repositories permissions:

  • Read access to code and metadata

• Add this token as environment variable GITHUB_BACKUP_TOKEN (GITHUB_BACKUP_TOKEN="[PUT YOUR TOKEN HERE BETWEEN THE QUOTES]").

• Add the target github name as environment variable GITHUB_BACKUP_USER (GITHUB_BACKUP_USER="[PUT THE TARGET USERNAME]").

• Ensure the environment variable GITHUB_BACKUP_PATH backup path is correct and set (GITHUB_BACKUP_PATH="/volume1/serverBackups/github/backup").

Node.js way

Prerequist

• Ensure you have node.js 18 (or later) installed.

Note: on DSM Synology - this can be download from the SynoCommunity.

Installation

• Copy ./build/github-backup.js over to your Synology/Server/[...].

Note: on DSM Synology - all via SSH.

Usage

# Without token (public repositories)
GITHUB_BACKUP_PATH=./backups GITHUB_BACKUP_USER=microsoft node ./github-backup.js

# With token (public+private repositories)
GITHUB_BACKUP_PATH=./backups GITHUB_BACKUP_TOKEN=XXXX node ./github-backup.js

/bin/sh way

Prerequist

• cUrl
• jq but these seem standard on Synologys.

Installation

• Copy the script (./scripts/github-backup.sh) over to your Synology/Server/[...].

Note: on DSM Synology - all via SSH.

Usage

# Without token (public repositories)
GITHUB_BACKUP_PATH=./backups GITHUB_BACKUP_USER=microsoft ./github-backup.sh

# With token (public+private repositories)
GITHUB_BACKUP_PATH=./backups GITHUB_BACKUP_TOKEN=XXXX ./github-backup.sh

Bonus - Gitea

Prerequist

• Generate a token with this command:

curl -H "Content-Type: application/json" -d '{\"name\":\"<Token Name>\"}' -u <user>:<password> http://<gitea-host>/api/v1/users/<user>/tokens
# {"id":1,"name":"Token Name","sha1":"XXXXX","token_last_eight":"YYYYY"}
# The token: the sha1 value.

Auto push to Gitea

GITHUB_BACKUP_PATH=./backups GITHUB_BACKUP_USER=creadigme GITHUB_BACKUP_TOKEN=[GITHUB_TOKEN] GITEA_URL=[GITEA_URL] GITEA_USER=[GITEA_USER] GITEA_API_TOKEN=[GITEA_TOKEN] EXTRA_REPO_STEP=./scripts/mirror-2-gitea.sh ./scripts/github-backup.sh
