Your stomach cramps really, really badly at the moment you realize that drive just failed and you don't have those photos anywhere else. I personally have 4 copies of all my photos on these drives. One of them stays at my office (away from the house, in case it burns) and I bring it home once a week to perform the backup, then it goes back to the office with me the next morning.

Bruce makes an excellent point. Getting the files OFF your iMac does not constitute a back up of the images. You are still at risk if the MyBook fails, which is just as possible as a computer hard drive failure.
Backing up data is NOT about the location of files. It is about the redundancy, or how many copies you have of your files.
Bruce is right that at the very least you need to have another external drive that mirrors the location of your files, if you are storing them OFF the computer to keep the originals.
There is one more tip to be aware of.
When you do post processing on your files, it's best NOT to edit them from the location on the external drive.
When you post process (edit) an image, you should move the file being edited back into your computer, either in a "work" folder or on a second hard drive INSIDE the computer.
Working with a file across an external interface like the one to your MyBook (USB??) slows down the editing because of the constant reads and writes of post processing across a slower interface than the internal bus of the computer.
So, there is nothing wrong with what you are doing because of limited space on your hard drive, you are still not "backing up" your date until you have at least one level of redundancy, which would take a second drive, or other location. Also, if you do your post processing by moving the PP file into the primary hard drive, or a second hard drive on the interface inside your computer, if it is possible to do that with your computer. That may not be possible, but it's a common practice with computers that will accept another internal hard drive.
Suggestion:
Remove all unnecessary programs on your computer. Get the hard drive gleaned down for more space, or consider a larger hard drive in the computer. Then keep your photos on the computer, and use the new MyBook for a "real" backup or redundant copy of your files.
Cost may be a factor, but I agree with Bruce on this. One external drive with your files on it, and no image files in the computer still leaves you at risk for data loss of your files.
I've seen more external drives fail as a result of too much activity over the slower interface (post processing over the slow interface) and the extra circuitry of the electronics in the external drive enclosure. This over 25 years of working on PC's......
I keep my files on my computer for the most part, using a large internal drive
I use three external drives, two synchronized to duplicate, which I rotate at home, and the third kept off site and updated quarterly.
I do not, and will never use Optical Media... CD's or DVD's for archived permanent storage, as well as I will not use Cloud Storage. Again, have seen many lose archived data on those operations. Cloud storage is only as good as the financial stability of the web sites hosting the stored data. Those web site come and go, often without warning and with no access to data post-disappearance.
And YES, I would not tell this story unless I had personally lost data (image files), or clients have lost data, from the closure of web hosts that did not survive on the internet.
My one rule...
You cannot pass the responsibility for your data to another party without increasing your risk of loss!!! :!:
