A lightweight way to accomplish this is to at least set up frequent autosaves in your editor. I had `au FocusLost * :wa` in vim to save all buffers to disk whenever it loses focus. Now that I've converted to the church of VS Code (with vim bindings, of course), there's an "Auto Save: onFocusChange" config option to do the same thing. I don't know how people live without it!
You don't always want to save to disk though, you want to save in a consistent state. Vim allows you to set up a persistent undo that will let you load the modified buffer from a backup file without touching the original until you're ready. Or undo back to the saved on disk version. Or undo even further to previous versions. That's true persistence.
