From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Set up a proper backup system for your server. I like to use borg. Just to be safe, make a copy of your drive as well (like full disk rsync). Then do a clean install and restore as if your drive had failed. If your backups missed anything, you will now know and can fix your backup system and can still recover from your rsync'd drive.
You might also want to take this opportunity to start administering your server with code, like using ansible or other remote provisioning tools. This makes your system configuration reproducible so that you only really need to back up a few kinds of data like media files or databases.
