VPS Backup Automation

Overview

This repository contains a set of Bash scripts for automating backups on multiple VPS servers. The system securely creates, synchronizes, and stores backups using rsync and rclone, with Telegram notifications for status updates.

• 📌 For detailed setup and usage of rclone, see: Rclone
• 📌 If you need a reliable VPS for hosting your backups, you can find options on: VPS & VDS Hosting

Files in this repository

1. backup_script_vps.sh

This script runs directly on each VPS to:

• Create daily, weekly, and monthly backups of website files and MySQL databases.
• Compress and organize backups into a structured directory.
• Ensure old backups are rotated according to retention policies.
• Send notifications to Telegram about backup status.

This script can work autonomously on any VPS to handle local backup generation.

2. sync_vps_backups.sh

This script runs on a centralized backup server to:

• Connect via SSH to multiple VPS servers and fetch backups using rsync.
• Store retrieved backups in a local directory (/root/google_sync/).
• Upload backups to Google Drive using rclone, ensuring no files are lost.
• Keep deleted backups in a separate folder (old_backups/) on Google Drive for manual removal.
• Send a Telegram notification after sync completion.

3. .backup_env

A configuration file that stores environment variables such as:

• MySQL credentials (if .my.cnf is not used)
• Telegram bot token and chat ID

Installation and Usage

Step 1: Clone the repository

git clone https://github.com/darkfire13/vps-backup-automation.git
cd vps-backup-automation

Step 2: Configure environment variables

Create and edit /root/.backup_env:

nano /root/.backup_env

Example configuration:

TELEGRAM_BOT_TOKEN="your_telegram_bot_token"
TELEGRAM_CHAT_ID="your_chat_id"
DB_USER="your_mysql_user"
DB_PASS="your_mysql_password"

Step 3: Set up SSH key authentication

Generate and copy SSH keys to all VPS servers:

ssh-keygen -t ed25519 -C "backup@server" -f ~/.ssh/id_ed25519
ssh-copy-id -i ~/.ssh/id_ed25519.pub root@your_vps_name

Ensure each VPS is added to /etc/hosts with a human-readable name.

Step 4: Set up cron jobs

On each VPS (for local backups):

30 4 * * * /bin/bash /root/backup_script_vps.sh >> /var/log/backup.log 2>&1

On the backup server (for syncing and Google Drive upload):

0 6 * * * /bin/bash /root/sync_vps_backups.sh >> /var/log/backup_sync.log 2>&1

Notes

• The backup_script_vps.sh can work independently on any VPS to generate backups.
• The sync_vps_backups.sh fetches all backups from multiple VPS and uploads them to Google Drive.
• Deleted backups are moved to old_backups/ on Google Drive instead of being permanently deleted.
• Telegram notifications are sent in case of success or failure.
