I've been using Robocopy for some time now, after reading Greg Schultz's article, and comes with Vista and 7. It's a manual backup, replacing Xcopy, but it has many switches and works well. I used an Xcopy batch file in XP and put it in the Task Scheduler. Both worked well and handled my backup needs. My files are backup up to my NAS, a Dlink DNS-321 network storage device on my home network with mirrored drives. My wife's and my computer are backed up to it.
