Proxmox PVE Host Config Backup Script

This script can be used to backup essential configuration files from the Proxmox Virtual Enivronment (PVE) host.

The script will create backups using tar with specified backup prefix and date and time stamp in the file name. Script will also delete backups that are older then number of days specified.

Create backup script file

To create backup script that will be executed every day we can create backup script in /etc/cron.daily/ folder. We need to make it writeable by root (creator) only, but readable and executable by everyone:

touch /etc/cron.daily/pvehost-backup

	#!/bin/bash

	# Check if database name is provided
	if [ $# -lt 1 ]; then
	echo "USAGE: $0 DATABASE_NAME"
	exit 1
	fi

	DATABASE=$1

	#!/bin/bash
	####
	# SMB: I got this script from here and customized it:
	# https://gist.github.com/m-faraz/4e32cbae283e3a9454118cd1d281f8cf
	#
	# Call like (should be run in its own folder!):
	# ./mysql_splitdump_v2.sh shisha-koenig-2024-06-07-02-15-01.sql
	#
	####
	# Split MySQL dump SQL file into one file per table

	sudo su &&
	cd &&
	wget https://prosody.im/files/prosody-debian-packages.key -O- \| sudo apt-key add - &&
	echo deb http://packages.prosody.im/debian $(lsb_release -sc) main \| sudo tee -a /etc/apt/sources.list &&
	apt-get update -y &&
	apt-get upgrade -y &&
	apt-get install prosody -y &&
	chown root:prosody /etc/prosody/certs/localhost.key &&
	chmod 644 /etc/prosody/certs/localhost.key &&
	cp /etc/prosody/certs/localhost.key /etc/ssl &&

	#!/bin/bash

	# This assumes that the ~6GB mojave installer is in the /Applications folder.
	# If it's not, just open the App Store, search Mojave, and you can download the installer file from there.
