Overview of this book

Proxmox VE's intuitive interface, high availability, and unique central management system puts it on par with the world’s best virtualization platforms. Its simplicity and high quality of service is what makes it the foremost choice for most system administrators. Starting with a step-by-step installation of Proxmox nodes along with an illustrated tour of Proxmox graphical user interface where you will spend most of your time managing a cluster, this book will get you up and running with the mechanisms of Proxmox VE. Various entities such as Cluster, Storage, and Firewall are also covered in an easy to understand format. You will then explore various backup solutions and restore mechanisms, thus learning to keep your applications and servers safe.

Any changes made to the file will not be replicated across the cluster. All the default backup configurations are encoded in the operating system. Any changes made to this file will override any default backup settings.

How to do it...

The following screenshot shows vzdump.conf as it appears on a Proxmox node:

By default, all the options are commented. To change an option, simply uncomment and set a value for each option. Here are some of the most commonly used options and their functions.

#bwlimit

This option sets the network bandwidth consumption during backup jobs. The limit must be defined in KBPS. For example, if we want to restrict the backup to 500 Mbps, we will change the limit as follows in the vzdump.conf file:

bwlimit 500000

#lockwait
