Automated Proxmox VM / LXC Container Backup and Google Drive Upload Script

This repository contains a bash script to automate the backup of VMs and LXC containers on Proxmox VE7 / VE8. The script performs weekly backups, uploads them to separate Google Drive accounts using Rclone, and manages old backups by automatically deleting them after a specified period.

Repository Information

Table of Contents

Prerequisites

Before running this script, ensure you have the following installed and configured on your Proxmox VE 7 server:

  1. Proxmox VE 7: Ensure that your system is running Proxmox VE 7.

  2. Rclone: Install Rclone to manage Google Drive connections.

    • Installation: 
      sudo apt update
sudo apt install rclone
    • Configure Rclone for each of your Google Drive accounts. Example: 
      rclone config
      • Follow the prompts to configure each Google Drive remote (e.g., citplvmbackup1, citplvmbackup2, citplvmbackup3).

  3. Bash Shell: The script is written in bash, so ensure you have a bash shell available.

  4. Proxmox Permissions: You need root or equivalent sudo permissions to run the backup command (vzdump) and manage system files.

    • Ensure you can run the script with root privileges: 
      sudo bash Automated-Proxmox-Backup.sh

Installation and Configuration

  1. Clone the Repository: Begin by cloning the repository to your Proxmox server.

    git clone https://github.com/Lalatenduswain/Automated-Proxmox-Backup.git
cd Automated-Proxmox-Backup

  2. Script Configuration: The script is pre-configured to work with specific VMs or LXC containers. You can modify the VM_RCLONE_MAP section to adjust the VM IDs and corresponding Rclone remotes if needed.

  3. Set Execute Permissions: Ensure the script has execute permissions.

    chmod +x Automated-Proxmox-Backup.sh

Usage

Running the Script Manually

To run the backup and upload script manually, execute the following command:

sudo ./Automated-Proxmox-Backup.sh

The script will:

  • Backup the specified VMs and LXC containers.
  • Compress the backup files using zstd.
  • Upload the backup files to the corresponding Google Drive accounts via Rclone.
  • Automatically delete old backup files based on the retention period (default: 7 days).

Script Details

The script iterates through the VM IDs and performs the following actions:

  1. Backup: It uses the vzdump command to create a backup with Zstd compression.
  2. Upload: The backup file is uploaded to the appropriate Google Drive account using Rclone.
  3. Cleanup: Old backups are deleted from the local directory based on the retention period.

Scheduling Backups

To automate the backup process, you can schedule the script using cron.

  1. Edit Crontab: Open the crontab file. 
    crontab -e
  2. Add Cron Job: Add the following line to schedule the script to run every Sunday at 2 AM: 
    0 2 * * 0 /path/to/Automated-Proxmox-Backup.sh
    Replace /path/to/Automated-Proxmox-Backup.sh with the actual path to the script.
