There are few situations in which a typical Mac user will need the latter, but if you do, CCC will oblige, provided CCC is able to unmount both the source and the target-which means you can’t be booted from either-and you choose the option to erase the target volume. This method makes a clone that’s not only file-by-file identical, but also block-by-block identical. One unique option here is the ability to make a block-level clone. To be fair, SuperDuper uses the text “What’s Going To Happen,” so there is-or there’s, depending on your inclination-at least one difference in the wording.) The process isn’t fast, but it’s thorough. (In a not-so-subtle nod to SuperDuper, you’ll see a clear description of the backup operation in the What Is Going To Happen box. Click on Clone and an exact copy of the source disk will be made using the target disk. You just choose a source disk (the original volume) and a target disk (the backup volume) choose Copy Everything From Source To Target from the Cloning Options pop-up and, optionally, enable the option to Erase The Target Volume.

Many people, including myself, considered it to be an invaluable tool for any Mac OS X user.Ĭarbon Copy Cloner, like SuperDuper, lets you easily create just such a clone.
With that in mind, it seems an opportune time to cover a recent-and major-update to one of the oldest Mac Gems, Mike Bombich’s Carbon Copy Cloner.įirst reviewed back in July 2002, Carbon Copy Cloner was, at the time, the only utility that could reliably duplicate a Mac OS X volume, making a bootable clone. (On the other hand, there are few computer-related disasters worse than not having a backup and then losing data thanks to a problem with an upgrade.) There’s no upgrade-related problem so big that it can’t be fixed by erasing your drive and restoring it to its pre-upgrade state. But the most important thing to do beforehand is back up. Upgrading to a major new version of a computer’s operating system is a major undertaking, no matter how easy the process is supposed to be as you’ll see in our upgrade guide, to be published on Friday, there are a number of choices to be made and precautions to be taken.

Unless you’ve been locked in a room somewhere for the past few months, you know that Friday is the official release date for Mac OS X 10.5, a.k.a., Leopard.
