Will time machine automatically backup my computer and an external hard drive at the same time?

Yes, if you select both as backup disks in System Preferences > Time Machine > Select Disk it will backup both. Not at the same time but first one, then the other.
I don't think I made my self clear. I want to back up my computer and my external harddrive plugged into my computer, both to another portable hard drive I have selected?
