Snapshot Cleanup Script (snapremove.sh)

This script removes snapshots older than 3 days for all virtual machines (VMs) across all nodes in a Proxmox cluster. It automates snapshot management to save storage space and keep your Proxmox environment tidy.

Requirements

• Proxmox Cluster: Ensure the script is run on a Proxmox node.
• Tools:
  • pvesh (Proxmox API CLI) must be available.
  • jq (JSON parser) must be installed. Install it using: apt update && apt install -y jq

Installation

1. Download the Script: Save the script as snapremove.sh on a Proxmox node.

   Example: nano /usr/local/bin/snapremove.sh

   Paste the script content and save

   chmod +x /usr/local/bin/snapremove.sh

2. Verify Functionality: Run the script manually to verify: /usr/local/bin/snapremove.sh

3. Automate with Crontab: Add the script to the cron scheduler for automatic daily execution.

   Edit the crontab file: crontab -e

   Add the following line to run the script daily at 2 AM: 0 2 * * * /usr/local/bin/snapremove.sh >> /var/log/snapremove.log 2>&1

   • This will log output to /var/log/snapremove.log.

Notes

• Only snapshots older than 3 days are removed.
• Ensure the script is tested in your environment before adding it to cron.
• You can adjust the age threshold by modifying the AGE_LIMIT variable in the script: AGE_LIMIT=$((N * 24 * 3600)) # Replace N with the desired number of days
