The Proxmox VE server runs the virtualization platform and provides access to storage, networks, and VMs during backup and restore. With the current release and upgrade to Proxmox 9.0. In order for Veeam to be able to correctly protect the Proxmox workloads, there is a need to update Veeam Backup for Proxmox to support PVE 9.0. Please, see this guide for the architecture and how to Backup and Restore Proxmox VE virtual machines with Veeam.

The Proxmox VE Plug-in integrates the backup server with the Proxmox VE server and enables worker deployment. From version 12.3.1 and above, you do not have to manually install this plugin.
