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

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

Follow standard conventions.
Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
Boy scout rule. Leave the campground cleaner than you found it.
Always find root cause. Always look for the root cause of a problem.
