Within OSX, two great drive cloning utilities are available; SuperDuper and CCC. I'm looking for an equivalent within the Windows world. Utilities such as Ghost, Acronis, and Clonezilla initially look promising, but from what I can tell don't support cloning an active boot drive.
Also, the Mac utilities allow the clone show up as a true clone, not an image file. So, if I plug the backup into a new computer, I'm able to boot from the backup and get my exact environment.
Are there any utilities available for Windows that mimic the functionality provided by SuperDuper and CCC for active boot drives? (meaning, not having to boot from a CD or other disk to back up)
Edit: Thanks everyone, I've decided to try out Acronis to see if it works the way I expect. If not, will move onto Ghost.
