🗄️ backup-action

GitHub Action for backing up DB & Directories.

First of all, Thanks 🙏 to @appleboy for drone-ssh & ssh-action to make this happen.

Heads up !! Notes

This action backups the things and store it to /github/workspace/backups folder inside the container. You can attach several actions available at the Marketplace and store this backup to your choice of location.

Pre Requisites

• SSH Key Access to Remote Server. How to setup?

Example Usecase

name: backup db
on:
  schedule:
    - cron: "0 10 * * 1" # Every Monday at 10 AM UTC
jobs:
  build:
    name: Build
    runs-on: ubuntu-latest
    steps:
    - name: Backup MySQL DB
      uses: valerianpereira/backup-action@master
      with:
        host: ${{ secrets.HOST }}
        username: ${{ secrets.USERNAME }}
        password: ${{ secrets.PASSWORD }}
        port: ${{ secrets.PORT }}
        key: ${{ secrets.DEPLOY_KEY }}
        type: db
        db_type: mysql
        db_user: ${{ secrets.MYSQL_USER }}
        db_pass: ${{ secrets.MYSQL_PASS }}
        db_port: 3306
        db_name: world

output:

Setting up SSH Key

Login to Remote Server

Make sure to follow the below steps while creating SSH Keys and using them. Login with username specified in Github Secrets. Generate a RSA Key-Pair:

ssh-keygen -t rsa -b 4096 -C "your_email@example.com"

Add newly generated key into Authorized keys. Read more about authorized keys here.

cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

Copy Private Key content and paste in Github Secrets.

clip < ~/.ssh/id_rsa

See the detail information about SSH login without password

Disclaimer

• Check your keys.
• Check your custom scripts properly.
• Pass all credentials from Github Secrets.
• Pass DB Credentials with Read-only access to database.
• Use it at your own risk! 🙏

Roadmap

• Add Backup & Restore Commands Explanations to ReadME
• Features to generate Backup Reports and Store it in txt file.
