How to design snapshots in openSUSE with YaST2 – Guide
Snapshots are a simple way to roll back configuration errors and different issues. With openSUSE, working with snapshots is incredibly simple. Jack Wallen shows you how. OpenSUSE is yet another exceptional Linux circulation that brings a lot to the table. Many accept that openSUSE is perhaps the best type of Linux for enterprise desktop use cases. One of the many purposes behind this is the implicit snapshot tool, conceived by a combination of the btrfs document system and the snapper module of YaST2.
What are snapshots?
Before we dive into it, you might be wondering what these snapshots I always refer to. Think of it this way: A snapshot is a snapshot of the time on your computer’s file system that you’ve saved if something goes wrong. If this inevitably happens, you can revert the file system to an earlier state. In simpler terms, it’s a backup. Out of the box, openSUSE is configured up to automatically create specific snapshots. When you run the tool for the first time, you will find snapshots of moments like: In another words, any important event will start to create a snapshot. However, there may be times when you want to create a snapshot manually. For example, let’s say you want to make a big change to your system configuration. Before doing this, create a snapshot. If something goes wrong, you can always go back to the snapshot you created before the configuration change.
What do you need
All you need for this is a running instance of openSUSE. I want to demonstrate with Tumbleweed (the release version of openSUSE), but you can choose to go with Leap (the static release version). And that’s all you need. Let’s see how this works.

If this change caused problems, you can click Restore selected to return to snapshot mode. And how easy it is to manage snapshots in openSUSE. This is one of those tools you hope you’ll never have to use, but you’ll be grateful it’s there if the opportunity arises.
