If you're a perpetual editor/nitpicker in drafts and your editing includes cutting large sections of text (like me!), it's helpful to back up your work periodically in a new file. That way you can always go back to an earlier version if you need to rescue something you inadvertently cut. To make it easy, I use a current file (NAMEOFNOVEL-CURRENT) and then save my back up files using the date for easy retrieval. Such as:
Heather does this for each draft! Isn't she so organized? I only back up drafts when I'm revising and making huge changes, but I think I'm going to adopt this method from now on. It has to be nice in those instances where you've rewritten a paragraph or chapter and think you might have liked the first version best after all. And it means you're constantly backing up as well. Thanks Heather!
