It appears that at least once when I did this I had shot myself in the foot. Please check to see if the kernel thinks root was mounted twice.
What appears to have happened to me was that when I booted with the esata device powered off, the esata device was /dev/sdc. When I booted with the device powered on, the _root device_ became /dev/sdc. And rather stupidly, I mounted /dev/sdc as my backup device. If you can see if that's what I did here, then the bug is that it let me mount root twice, or that I'm stupid.
