How to Backup and Restore Virtual Machines in Proxmox

How to Backup and Restore Virtual Machines in Proxmox


This is our fourth guide of the Proxmox series, in this tutorial, we will explore how to backup and restore VMs in Promox. As a prerequisite, ensure that you already have a virtual machine running on your Proxmox instance.

Take a look at our earlier tutorials on Proxmox.

Without much further ado, let’s get started!

Step 1: Poweroff the VM in Proxmox

First off, you need to shut down your virtual machine before taking a backup of your VM. On the Proxmox dashboard, right-click on your virtual machine and select the ‘Shutdown‘ option.

While you can still create the backup on the proxmox server itself, it’s recommended to save it in a different location so that in case something goes wrong with the server, the backup copy will still be recoverable.

Be sure to go with ZSTD compression which is preselected by default owing to its high performance and click ‘Backup‘.
