Backup and Restore: How to view or change the current config?

How can I view the current configuration of Backup and Restore? Let's assume I set it up already, but can't remember what I selected at that time.

If the answer is "it backs up your hard drive", please note that a hard drive may be partitioned, possibly dual-boot (with Linux or whatever), and/or there may be multiple internal hard drives, and/or external hard drives as well.

So, is there a way to find out, before clicking "Back up now", what it's going to back up?

Also, what if I want to change that, how do I do it?

I found some articles via Google entitled ""what does windows 7 backup actually backup" but then they don't answer the above.
