Automate and Secure Proxmox Backups with Ansible

Automate and secure your virtual machines with Ansible Proxmox backup efficiently. Our Proxmox Support team is ready to assist you. 

Automate and Secure Proxmox Backups with Ansible

Automating Proxmox backups with Ansible ensures your virtual machines and configurations are protected consistently. It saves time, reduces errors, and allows scheduled backups across multiple servers without manual effort.

Automating Proxmox Backups with Ansible

Automating backups in Proxmox with Ansible ensures your virtual machines are protected without manual effort. This approach is reliable, consistent, and scalable for small and large environments alike.

Setting up proper configuration also helps in troubleshooting issues with Proxmox remote access, ensuring that automated tasks run smoothly even when managing VMs from different locations.

Install Ansible

Set up Ansible on a control machine. This machine will manage backup tasks across all your Proxmox servers by executing playbooks.

Configure Your Inventory

Create an inventory file to define your Proxmox hosts. This file lists all servers that Ansible will manage.

Example Inventory

[proxmox_servers]

pve1.example.com

pve2.example.com

Create an Ansible Playbook

Write a playbook in YAML format to define backup tasks. Use API tokens for security instead of passwords.

Example Playbook

---

- name: Perform Proxmox Backups

hosts: proxmox_servers

tasks:

- name: Create VM backup

proxmox_kvm_backup

node: "pve1"

vmid: 100

storage: "backup"

api_user: "ansible@pve"

api_token_id: "ansible_token"

api_token_secret: "your_api_token_secret"

compress: true

rotation: 3

This setup is also compatible with specialized configurations such as Proxmox ARM64 Guest Setup, allowing automated backups for ARM64 virtual machines without extra adjustments.

Run the Playbook

Execute the playbook from the control machine using:

ansible-playbook -i inventory.ini backup_playbook.yaml

This runs the defined backup tasks on all servers in your inventory.

Automate and Schedule

To ensure backups run regularly, integrate the playbook with a scheduling system.

Options for Automation

• Cron Jobs: Schedule recurring execution on the control machine
• Ansible Tower or AWX: Manage schedules, monitor backups, and get reports

Proxmox Backup Role with Ansible

The proxmox_backup Ansible role simplifies backing up your Proxmox configuration. It wraps the prox_config_backup.sh script from GitHub, providing customizable options for backup directories, temporary storage, logging, and scheduling. This approach ensures consistent, reliable, and automated configuration backups with minimal effort.

Requirements

• Ansible version 2.7 or higher
• Access to the Proxmox host

Key Role Variables

Variable	Default	Description
proxmox_backup_script_url	GitHub URL	Source to download the backup script
proxmox_backup_wrapper_script_path	/usr/local/sbin/prox_config_backup_wrapper.sh	Path for the wrapper script
proxmox_backup_temp_dir	/var/tmp	Temporary folder used during backup
proxmox_backup_log_file	{{ proxmox_backup_log_dir }}/pve-backup.log	Path for the log file
proxmox_backup_script_path	/usr/local/sbin/prox_config_backup.sh	Path of the script on Proxmox
proxmox_backup_dir	/mnt/backups/proxmox	Directory to store backups
proxmox_backup_log_dir	/var/log/pve-backup	Directory for backup logs
proxmox_backup_cron_configure	false	Enable or disable automatic cron scheduling

Cronjob Configuration

You can schedule backups automatically by enabling proxmox_backup_cron_configure. Control the timing using these optional variables:

• proxmox_backup_cron_minute
• proxmox_backup_cron_hour
• proxmox_backup_cron_day
• proxmox_backup_cron_month
• proxmox_backup_cron_weekday
• proxmox_backup_cron_special_time

This ensures backups run on your preferred schedule without manual intervention.
