When planning to reinstall your Proxmox VE (PVE) environment, preserving your virtual machine (VM) configurations—especially for services like pfsense, Jellyfin, and Windows—is critical. In this guide, we’ll explore Proxmox VE VM backup and restore during reinstall using a range of professional strategies. These approaches ensure minimal downtime and data loss, whether you’re performing a full system reinstall or migrating to new hardware.
Backup and Restore Strategies for Proxmox VE VMs
Beginner-Friendly: Basic Proxmox VE Backup and Recovery Steps
- Use Proxmox VE’s built-in VM backup tool to create full or snapshot backups.
- Transfer backup files to an external drive or remote server using SCP or rsync.
- After reinstalling Proxmox, restore VMs using the GUI or CLI for a quick VM recovery.
Intermediate Level: Backing Up Configuration and VM Images
- Back up
/etc/pve/to retain Proxmox VE cluster configuration and settings. - Perform VM backups with the Proxmox built-in scheduler or manually via
vzdump. - After Proxmox VE reinstall, restore configurations and use VM restore procedures to bring your environment back online.
Advanced Proxmox Reinstallation with VM Migration
- Use Proxmox clustering to live migrate VMs to another node before reinstallation.
- Reinstall the original host, rejoin the cluster, and migrate VMs back.
- Alternatively, use
qm remote-migrateto move VMs between hosts without a full cluster setup.
Off-Site and External Backup Options for Reinstall Safety
- Use a USB hard drive for physical backups, ideal for offline Proxmox VE reinstall scenarios.
- Configure NFS storage on a secondary server to hold Proxmox VM backups remotely.
- Automate regular backups to a dedicated Proxmox backup server for long-term security and fast recovery.
