Can I use one time capsule to backup a second one used as wireless storage?

I want to purchase 2 Time Capsules and setup one to be a wireless network drive, to store movies and music on and setup the other as a Time Machine backup drive. Will Time Machine backup both my MacBook Pro and the contents on the other Time Capsule (being used as an external drive)?
