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

WireGuard Site-to-Site

Accessing a subnet that is behind a WireGuard client using a site-to-site setup

Problem Summary

We want to access a local subnet remotely, but it is behind a NAT firewall and we can't setup port forwarding. Outgoing connections work, but all incoming connections get DROPPED by the ISP's routing policy.
