Overview of this book

Proxmox is an open source server virtualization solution that has enterprise-class features for managing virtual machines, for storage, and to virtualize both Linux and Windows application workloads. You'll begin with a refresher on the advanced installation features and the Proxmox GUI to familiarize yourself with the Proxmox VE hypervisor. Then, you'll move on to explore Proxmox under the hood, focusing on storage systems, such as Ceph, used with Proxmox. Moving on, you'll learn to manage KVM virtual machines, deploy Linux containers fast, and see how networking is handled in Proxmox. You'll also learn how to protect a cluster or a VM with a firewall and explore the new high availability features introduced in Proxmox VE 5.0. Next, you'll dive deeper into the backup/restore strategy and see how to properly update and upgrade a Proxmox node. Later, you'll learn how to monitor a Proxmox cluster and all of its components using Zabbix. Finally, you'll discover how to recover Promox from disaster strikes through some real-world examples. By the end of the book, you'll be an expert at making Proxmox work in production environments with minimal downtime.

Preface

Configuring backup storage


A sound backup strategy has a dedicated shared storage for the backup images instead of local storage or 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 ZFS and still manage the node through the Proxmox GUI. Unfortunately, we cannot store backup files on the Ceph RBD storage...
