A benefit of having reliable working backups besides not losing data is that you can take more risks that would otherwise result in data.
My server in the cloud was down to just 65 MB of free HD space just now. I have another static-web-archive instance
that I started years ago. It uses git for persistence. Now, I realize that that's not necessary and that the .git directory was taking up 13 GB. (There's a lot of media there.)
I was able to switch it to use the filesystem for persistence directly and delete that .git without worrying. It works fine. Now I can delay the question of what to move off the server for another couple of months!
