Nope, if it breaks, it's lost. However, I don't really think that's a practical issue. The workflow is going to be one where you write in chunks, and then copy over to your computer. After all, part of the appeal is that you can't edit anything beyond what you're currently typing right now, like a typewriter. However, you still need to edit eventually, and that naturally forces you to move data occasionally to your computer. And even if it does break, you probably remember what you wrote enough to recreate it anyway. If you're writing hundreds of pages at a time, it's probably a mess anyway.
