1) Pair ALL bluetooth devices in linux (it is to have the files you will need to edit later)
2) Pair ALL bluetooth devices in Windows 10. If you know how, get the MAC address id from your bluethooth keyboard, we will need it later
3) Reboot and go back to Linux
4) Install chntpw package, this is needed to read the registry keys from Wintendo
sudo apt-get install chntpw
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.
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

When you use ssh with X forwarding, you might have noticed that you cannot execute programs that require 3D acceleration. That's where VirtualGL comes into play.
