Can I back up my passport to my mybook elite?

Can I back up my passport which I use for additional storage to my mybook elite?

Manually yes. With the WD Smartware no unfortunately smartware only backups your main hardrive which has your OS on it. No secondary drives or memory sticks attached. By manually I mean copy and paste. Or you can copy onto the main hard drive and it will automatically back it up once it touches the desktop. Let me know how that works out.
