Windows vista is a file-based OS with a new file-based install (as compared with WinXP which wants certain files at certain places on the disk). What are the pros/cons of image-based backup vs file-based backup under the new OS? The ones I can see are: Image-based pretty much nixes defragmentation of drives (not an issue if always doing full images rather than incremental ones). File-based software is easier (trivial?) to implement. Bare metal restore not possible with file-based on XP but is possible (at least theoretically, I don't know what the licensing issues are) with Vista. (If doing only full backups, there is no size advantage of images over the entire set of files).
