Is Time Machine the best way to backup two external drives?

I only have the most basic understanding of Time Machine. I hook up an external drive to my MacBook Pro, click "backup now" on Time Machine, wait a while, and forget about it because I've never had to use it to retrieve a file - thank heaven.

Now I also have two external 2TB portable drives that are close to full and which need to be backed up. I just bought a 4TB drive that I haven't taken out of the box yet. Is it a simple matter to create two Time Machine files on the 4TB drive ... one for each of the 2TB drives?

And is Time Machine the best way to do this? Or is there some other system that makes more sense for backing up on this scale and with two drives?
