Mastering Proxmox - Second Edition

By: Wasim Ahmed

Overview of this book

Proxmox is an open source server virtualization solution that has enterprise-class features to manage virtual machines, to be used for storage, and to virtualize both Linux and Windows application workloads. You begin with refresher on the advanced installation features and the Proxmox GUI to familiarize yourself with the Proxmox VE hypervisor. You then move on to explore Proxmox under the hood, focusing on the storage systems used with Proxmox. Moving on, you will learn to manage KVM Virtual Machines and Linux Containers and see how networking is handled in Proxmox. You will then learn how to protect a cluster or a VM with a firewall and explore the new HA features introduced in Proxmox VE 4 along with the brand new HA simulator. Next, you will dive deeper into the backup/restore strategy followed by learning how to properly update and upgrade a Proxmox node. Later, you will learn how to monitor a Proxmox cluster and all of its components using Zabbix. By the end of the book, you will become an expert at making Proxmox environments work in production environments with minimum downtime.

Configuring backup storage


A sound backup strategy has a dedicated shared storage for the backup images instead of local storage that is used for the disk images themselves. This way, we can centralize the backup location and restore them even in the event of a Proxmox node failure. If the backup is stored locally on the same node, during hardware failures, that node may become completely inaccessible causing a VM restoration delay.

One of the most popular options for a backup storage node is NFS. In an enterprise or mission-critical environment, a cluster with built in redundancy dedicated to backups is a recommended practice. In smaller environments, good redundancy can still be achieved using storage options, such as Gluster or DRBD. With the addition of ZFS and Gluster in Proxmox VE, it is now a viable option to turn a Proxmox node into a backup using Gluster on top of ZFS, and still manage the node through the Proxmox GUI. Unfortunately, we cannot store backup files on the Ceph RBD storage...
