SuperDuper! is an advanced, yet easy to use disk copying program. It can, of course, make a straight copy, or “clone” — useful when you want to move all your data from one machine to another, or do a simple backup. In moments, you can completely duplicate your boot drive to another drive, partition, or image file.
Clones for safety. To ensure you can safely roll back a system after the unexpected occurs. With a few clicks, you can easily “checkpoint” your system, 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.
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 what files get copied, ignored, even aliased (“soft linked” for the Unix inclined) from one drive to another.
The latest version of SuperDuper! is faster, better, compatible with El Capitan (in fact, it's compatible with OS X 10.7 and later), and improves many parts of the user experience. Of course, it still includes great features like Backup on Connect, Eject after Copy, Sparse Bundle support, lets you store a bootable backup alongside Time Machine backups, copy Time Machine backups to other drives, and run scheduled copies on demand. As with every update, we've polished and improved many other aspects as well. (A full list can be found by selecting Help > Revision History.)
