If you want the files created, but do not want them visible, another option would be to set up a script that moves them from that location to another location:

Instead of the *.*;*, the syntax would just be *.wbk;* (or something along those lines I believe....it's been a while since I've done Windows scripting). Whether the "other location" is another folder on your computer, or perhaps a SAN, is really just a matter of personal preference. I should also note that this is just ADvice (and we all know that's the worst vice of all...). Do what you feel most comfortable with, and keep in mind that you should know your own level of comfort better than anyone as to what changes you make on your own systems.
