We are about to embark upon a new kind of virtual world, which is beyond just basic. Through previous chapters, we have familiarized ourselves with Proxmox up close and personal. We saw what a Proxmox GUI looks like and got our hands dirty with the Proxmox configuration files and directory structure. We also learned what shared storage system is and how it is integrated with the Proxmox cluster. In this chapter, we are going to take it one step further by covering at the following topics:
Advanced configuration options for virtual machines
Nested virtual environment
Proxmox backup/restore system
Virtual machine snapshots
Command-line backup
