Heads up for those of you (me included) who haven't purchased a backup βIMAGEβ program, on Giveaway of the Day http://www.giveawayoftheday.com/macrium-reflect/ todays free software is Macrium Reflect, an award winning disk imaging and file backup solution for Windows XP, Vista and Server 2003.
Disk Imaging: Using the latest compression and multi threading techniques, Macrium Reflect has unrivaled disk imaging speed. Full, differential and incremental images can be restored or mounted as a virtual drive in Windows Explorer.
Lots of good reviews for this one too.
