I use W7 back up. I don't really know what you mean by ghosting, but you can restore individual files from the backup.I switched after I discovered that Memeo, which is what comes with Seagate, wasn't backing up every file as I wanted - it said it was keeping it in sync, but it wasn't. And I have a really old WD drive, which came with some clunky software that I also didn't find useful.
Memeo came with my Buffalo external, and in my version you can select what you want to back up or not (i think default was just My Pictures, My Documents, and My Music)
running my very first VM thru Xp mode in W7. seem pretty cool. altho watching flash seems to jack the CPU usage to 100%
