Winclone can also be used to quickly deploy a Boot Camp image to a number of machines (e.g. in a lab). Mike reports that he recently used Winclone to successfully reimage the Windows side of 10 iMacs with only a few clicks, sending the image package and the install commands via Apple Remote Desktop. Comparing it to NetRestore, he likes Winclone better: "Using NetRestore requires a separate install of the ntfsprogs toolkit to add the NTFS restore tools. Winclone bundles the ntfsprogs tools and a Perl restore script in with the image, so it's portable -- just copy the image and run the script to restore the Windows boot environment."
Winclone is a free download from twocanoes software, and donations are requested. Macworld's Mac Gems blog has a thorough walkthrough of backup and restore of Boot Camp using Winclone.
