I just realized that I have not yet mention Winclone, one of the most useful software packages for backing up Windows computers, on the macintosh…
WinClone, quite simply, allows you to image / clone your XP or Vista based hard drive, and restore it to another drive or partition later…. It is quite similar to Ghost (Symantec\’s imaging software), but free.
Features

• Clone either FAT32 or NTFS partitions New
• Fixes boot issues automatically New
• New preference window to fine tune your cloning New
• Source partition is not changed when cloning (except for removal of pagefile.sys) New
• Clone Windows XP or Windows Vista with ease.
• Clone to your Bootcamp partition either on a separate drive or on the same that contains your Mac OS X partition.
• Creates image documents that can be stored on any media and double-clicked to open in WinClone.
• Verbose logging so you know what is going on
• Built on the open source ntfstools, which are included in Winclone, so you don\’t have to install anything else.
• Fast: Restore a 10 GB image in less than 10 minutes.
• Create a Bootcamp partition from within Winclone.
• Do it all from the boot drive: You don\’t need to boot from a Firewire drive to clone the Windows partition.
• Clean and uncomplicated interface
