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.

Snapshots seem an ideal tool for the job. It won't replace a full backup system, but as long as the cost of failure (such as you mistyping a command and nuking the disk's partition data or something) is only a few hours of OS reconfiguration rather than losing priceless family photos, it should work.
I use btrfs snapshots on my system. When I'm about to do something "risky" (e.g. trying out kde or cosmic) I take a snapshot beforehand. Then when I want to go back, I just restore the snapshot and reboot.
For /home, there won't be a lot of OS configuration there, and if it's a burner machine you probably won't have much personalisation done on it. However, if you want to backup configuration there, look into a dotfile manager.
