Proxmox Backup to Google Drive Script

This script uploads Proxmox backups to Google Drive and sends notifications to a Discord webhook. It supports the following features:

• Only uploads .zst files created in the last 24 hours.
• Creates a subdirectory on Google Drive with the format DD-MM-YYYY and copies the files into it.
• Deletes subdirectories older than a configurable number of days.
• Sends notifications to a Discord webhook when the backup process starts, after each file is uploaded, and when the process is complete.

Prerequisites

• rclone
• jq
• A Discord webhook URL

Setup

1. Clone the repository:

   git clone https://github.com/yourusername/proxmox-backup-to-gdrive.git
   cd proxmox-backup-to-gdrive

2. Configure the script:

   Edit the script to set your local directory, remote directory, and Discord webhook URL:

   nano backups_to_gdrive.sh

   Update the following variables:

   LOCAL_DIR="/path/to/local/backup/directory"
   REMOTE_DIR="remote:Backups/proxmox/"
   BACKUP_LIMIT_DAYS=30  # Number of days to keep
   WEBHOOK_URL="https://discord.com/api/webhooks/your-webhook-id/your-webhook-token"

3. Make the script executable:

   chmod +x backups_to_gdrive.sh

4. Create a systemd service and timer:

   Create a systemd service file:

   sudo nano /etc/systemd/system/backups_to_gdrive.service

   Add the following content:

   [Unit]
   Description=Backup Proxmox to Google Drive
   After=network.target
   
   [Service]
   Type=simple
   ExecStart=/path/to/your/script/backups_to_gdrive.sh

   Create a systemd timer file (or use cron to schedule the script execution):

   sudo nano /etc/systemd/system/backups_to_gdrive.timer

   Add the following content:

   [Unit]
   Description=Runs backups to Google Drive daily at 5 AM
   
   [Timer]
   OnCalendar=*-*-* 05:00:00
   Persistent=true
   
   [Install]
   WantedBy=timers.target

5. Enable and start the timer:

   sudo systemctl daemon-reload
   sudo systemctl enable backups_to_gdrive.timer
   sudo systemctl start backups_to_gdrive.timer

Usage

The script will run daily at 5 AM as configured. You can also run it manually:

./backups_to_gdrive.sh
