I did find this low-profile backpack:

They used to have a version called "Flashback" and it is made of reflective material. That's the one I got, last year (knowing that once it warmed up, I was not going to want this thing on my back).
So, I went to Ortlieb's website, navigated to the "Replacement Parts" page and ordered a full Ortlieb mounting system for my backpack. I pull the straps around to the back and secure them together with a small strap, hang the bag on my rack and it is not going anywhere.

Could you give more information on how you got the backpack to secure to your rack? I'm not following. If you have a link, that would be great! I think that's the way to go -- either get a backpack that can hook vertically to the side of my rack, or adapt my current backpack to do so (if possible). Or use panniers, as the other poster recommended.
Thanks!
