Editor’s note: The following review is part of Macworld’s GemFest 2013. Every day (except Sunday) from mid-July until late September, the Macworld staff will use the Mac Gems blog to briefly cover a standout free or low-cost program. You can view a list of this year’s apps, updated daily, on our handy GemFest page, and you can visit the Mac Gems homepage for past Mac Gems reviews.
OS X’s Boot Camp lets boot your Mac into Windows, temporarily turning it into a Windows PC. It’s a great feature, but if you value your Windows data—or if you want to be able to restore your Boot Camp partition to another Mac or to a new hard drive—you should back up your Windows partition just as you back up your OS X data. In my experience, many Boot Camp users don’t.
Part of the reason, I’m sure, is that even the best Mac backup software—including OS X’s own Time Machine—can’t properly back up a Boot Camp partition. And even standout Mac-cloning utilities such as SuperDuper and Carbon Copy Cloner are unable to make clones of your Boot Camp partition for migrating or restoring your Windows install.
To clone your Boot Camp partition, you just select it in Winclone’s Sources list, click the large Save Image icon in the Destinations pane to the right, and then click the Save Image button. If you plan on restoring to a Boot Camp partition that’s smaller than your current partition, the Shrink Windows (NTFS) Filesystem option lets you first compress your current Boot Camp installation. (For extra data security, the developer recommends running CHKDSK from within Windows before cloning. Similarly, if you’re migrating Windows installations between computers, you should use Windows’s SysPrep utility before cloning.) Choose a location for the saved image, and Winclone creates an OS X disk image containing a perfect clone of your Boot Camp partition.
Restoring that image is just as easy. You just select the image in Winclone’s Sources list, choose your (presumably empty) Boot Camp partition in the Destinations pane, and click Restore To Volume.
New in 4
The latest version of Winclone adds a number of useful new features. For example, you can now use Winclone to clone an actual Windows PC to a disk image for later restoring, or migrate an actual Windows PC directly to a Boot Camp partition on your Mac. Or if you want to migrate an existing Boot Camp partition to another Mac, you can skip the disk-image step by placing the source Mac in Target Disk Mode, connecting it (via FireWire or Thunderbolt) to the target Mac, and transfer the Boot Camp partition between them. You can even do the same with a real Windows PC, though this requires that you connect the PC’s hard drive directly to your Mac.
You can also now restore a Boot Camp partition over a local network by enabling the Share Winclone Images On Network option in Winclone, and then running Winclone on both the source and destination machines. The source Mac’s Boot Camp partition will appear in the destination Mac’s Source list. The source Mac will also share any clone images you’ve created.
(Note that you must have a Boot Camp partition on the destination Mac for any of these procedures. You can do this using Apple’s Boot Camp Assistant, or you can follow the developer’s instructions for manually creating a Boot Camp partition.)
As our GemFest reviews are brief, I’ve only summarized the capabilities of Winclone 4. Suffice it to say that if you use Boot Camp frequently, or on multiple Macs, Winclone should be in your tooklit. It’s easy to use, it works well, and the developer provides excellent how-to documentation.
(A $100 Pro version of Winclone 4, aimed at system administrators and multi-computer organizations, supports an unlimited number of computers and—my favorite pro-level feature—lets you create self-contained Boot Camp installers for quickly restoring a Boot Camp image to one or more Macs.)
