I'm going to be backing up everything on my computer to an external hard-drive. How do I make sure nothing on WoW changes when I want to log back in? I know that I can re-download WoW from battle.net after I login but I was wondering if there is any chance I'd lose add-on settings or anything like that. Would I just move my World of Warcraft folders back into the game folder? A step by step process would be great if someone could provide it, or any comments. Thanks for the help.
