That is not a "BACKUP" drive if those files are nowhere else ... that is your primary drive. You should probably make a true backup of that drive if the files it contains are important to you.

Hi Howard, I expected this question. Let me explain.
When it comes to backup strategies I don't take chances. I have two computers:
- a 2010 Mac Pro 5,1: only used for photography, no mail or other data
- a 2008 MacBook 5,1 (not Pro): used for everything else: mail, docs, etc.
The MP holds two internal 2TB drives (Source and Backup) that hold my RAW files and CCC maintains Backup as an exact clone of the source, every hour. Then I have two external 2TB drives that are also clones of "Source", one of which is at an external location and gets swapped every couple of weeks.
My Macbook backups with Time Machine on a USB drive on my Airport Extreme and on a local USB drive whenever I can connect it. On top of that, the most important data are backed up on the 2 external 2TB drives so my docs, mail and RAW files are all backed up on an external location.
Then, when my 2TB internal "Source" drive was nearing capacity, I was to decide what to do with the RAW files that were "rejected". I could simply delete them and free up space, but as a photographer I just wanted to be able to get back to them if needed so I rushed to the store and picked up a 3TB Seagate USB3 drive and copied all RAW files to that drive. I also use that drive as an extra backup for iTunes and some other things.
Even if this entire drive would get lost that would not be a huge problem for my photography, but I didn't buy it for nothing so I don't want to lose the files on it.
