Mastering Proxmox - Third Edition

By: Wasim Ahmed

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.

Backup configuration file


The backup configuration file in Proxmox allows more advanced options to be used. For example, if we want to limit the backup speed so that the backup task does not consume all of the available network bandwidth, we can limit it with the bwlimit option. As of Proxmox VE 5.0, the configuration file cannot be edited from the GUI. It has to be done from the CLI, using an editor. The backup configuration file can be found in /etc/vzdump.conf. The following is the default vzdump.conf file on a new Proxmox cluster:

# tmpdir: DIR 
# dumpdir: DIR 
# storage: STORAGE_ID 
# mode: snapshot|suspend|stop 
# bwlimit: KBPS 
# ionice: PRI 
# lockwait: MINUTES 
# stopwait: MINUTES 
# size: MB 
# stdexcludes: BOOLEAN
# mailto: ADDRESSLIST
# maxfiles: N 
# script: FILENAME 
# exclude-path: PATHLIST 
# pigz: N: 

All the options are commented in the file by default because Proxmox has a set of default options already encoded in the operating system. Changing the vzdump.conf file overwrites...
