See the two FAQs on config backup / location if you want to automate the backup (you just have to copy the contents of /dopusdata):
[How to backup or locate your Opus configuration (Simple))
[HOW TO: Backup or locate your Opus configuration (Advanced))
BTW if you want to see what a built-in toolbar/menu does, just edit it via Settings -> Customize, then right-click whatever you're interested in. There's nothing special about the built-in toolbars/menus. You can edit/delete/modify them or copy/move bits of them to other toolbars/menus.
