I’m sure you have a backup and that you’ve tested restoring it. Just have another machine that is available in the case something happens to the first.

E.g. I somehow fried the motherboard of my server while cleaning it. It took me days to troubleshoot the issue.

But I also have an old laptop strapped to the back of my TV that is used to stream media using Kodi. When this event happened, I installed a more appropriate OS on the TV laptop and restored my backup and was up and running in an hour or two. Then I could take the time to troubleshoot my issue and resolve it on my main server.
