In this chapter, we have covered some interesting topics, such as nested virtual environment, the hotplug feature, and Proxmox backup/restore. A good backup plan can save the day many times over. Although Proxmox does not provide everything you need for backup such as a granular file backup, to back up a virtual machine is very helpful. Backup features in the Proxmox platform have proven to be reliable in production environments and during actual disaster scenarios.

In the next chapter, we are going to look at an even more interesting topic: network virtualization. Although it is a fairly new concept, it is by no means immature. In an ever-growing virtual environment, a good virtualized network design can alleviate management issues without adding any overhead. We will see how we can take complete advantage of network virtualization in Proxmox to bind volumes of virtual machines together and ork in harmony.
