Disk cloning tools are a handy way to make a complete—and we do mean complete—backup of any system. Not just data, not just apps, you're grabbing everything on that disk, from boot sectors on up. This makes for a thorough backup, but might also be helpful in case of total catastrophic system meltdown—recreate your HDD exactly as it was. That could be handy!

Clonezilla is a free disk cloning tool. It works like Norton Ghost, but doesn't cost like it, since it's absolutely free. It supports just about every filesystem under the sun—FAT and NTFS for Windows, ext2 and ext3 for Linux and the like, and HFS+ for Mac users. It can even do a sector-by-sector copy for filesystems it doesn't understand. You can use it on just about any system that runs on i386 architecture, so most of your needs should be covered (sorry, not your PowerPC Mac).

Clonezilla runs as a Live CD, so even if you have only one partition or volume, you're not going to run into any "you can't image the boot volume" problems. Nice.

Clonezilla is a free download. They've also got a multicast version that will let you image a whole room full of computers at once, if you're so inclined.
