Physical Disks. I was thinking that in the case of no RAID (unwise, i know), the quickest way to get a Server back up on its feet is to pop in a drive that I had cloned earlier (sector by sector). This is assuming, of course, that the data was being backed up, and there hadn't been wholesale changes along the way.
I haven't practiced a lot of other disaster recovery methods yet on Windows Servers. I'm assuming that you pop in some kind of DVD, point it to the location of the backup, and have it restore to the new HD - much like Acronis?
