SuperDuper! 3.1.1 (Mac OSX)

Carbon copies. And a whole lot more.
SuperDuper is the most advanced, yet easy to use disk copying program available for OS X. It can, of course, make a full backup, or "clone" - in moments, you can completely duplicate your boot drive to another drive, partition, or image file. In even less time, you can update an existing clone with the latest data: use Smart Update and, minutes later, your backup is completely up to date!

Faster than a speeding bullet - and more accurate!
SuperDuper isn't just the most powerful cloner available: it's incredibly fast, too. Its Smart Update feature evaluates hundreds of thousands of files and directories in just minutes, automatically updating your clone to reflect any changes you've made on the original drive - including custom icons, HFS+ attributes, ownership changes... the works! It can even copy (and Smart Update) Time Machine backup volumes!

Ease of use
Expertise not required.
SuperDuper comes preconfigured, ready to perform all the most common copying and cloning tasks. We've pored over the Apple documentation so you don't have to. Every step of the process carefully follows all Apple recommended policies and procedures.
Whether you're making a full backup to a disk image, using Smart Update to update an existing backup, or making a complex clone to test a software update, the process couldn't be simpler: select the source drive, the destination and the appropriate script. Click Copy Now, and SuperDuper does the rest.

Experts
Clones for experts.
Regular backups aren't always the best way to recover for the risk takers out there who jump on every software update. Unless you take specific steps, fully restoring a backup restores everything on the drive, overwriting both the system and user files. If that's what you want to do, great. But it usually isn't, because everything you've done since the backup would be lost!
With SuperDuper, though, you can easily "checkpoint" your system with a Sandbox, preserving your computer's critical applications and files while you run on a working, bootable copy. If anything goes wrong, just reboot to the original. When you do, your current Documents, Music, Pictures - even iSync data - are available! You can get back to work immediately!

Testers
Clones for industry!
SuperDuper has enough features to satisfy the advanced user, too. Its simple-but-powerful Copy Script feature allows complete control of exactly which files get copied, ignored, even aliased ("soft linked" for the Unix inclined) from one drive to another!

Compatibility: OS X 10.8 or later
