Ok I figured this out on my own. I have my DNS-323 set up in "Standard" mode so I have two volumes. In the Easy Search utility I started configuration and instead of going into configuration I selcted downloads. I then set up a recurring backup of Volume 1 to Volume 2. It appears to work for me. Hopefully that is a "correct" solution for my scenario.
I have to say that the documentation and the tool are not "in your face" on how to accomplish this type of backup. I think a little more documentation on how to use each of the types of configurations (standard, RAID 1, JBOD, etc.) would be most excellent!
