We are aware that our current DR ability is not very good or timely. That's part of what we want to address with newer machines. If we do this, we're talking about the dasd mirror being across campus or further. We're not in an area prone to natural disasters. We're more worried about human (electricia, plumber) or fire. It's currently viewed that our primary site is far enough from the vault to avoid simultaneous disasters.
