All of the tools I use are free software and actively maintained and updated, plus they have very nice logging, so I can diagnose what's happening. I only needed to read the logs because I was young and experimenting with the parts I shouldn't and broke the thing on purpose. However, you can just create a copy of the installation directory to back it up completely.
Again, the tool I gave as an example has integrated configuration snapshots, and if something breaks I can revert to a config 2 seconds or 2 years before, including component versions installed at that time.
To be honest, I probably used that feature at most two times in the last 20 years.
Workplace restrictions something off-limits and I can't tell anything about. The people I gave examples are persons I know and they have no such restrictions in place.
