SuperDuper! 是一款数据恢复及备份工具。 可以帮助你恢复你电脑误删除文件，甚至格式化后丢失的数据。
同时，它能够在 OS X 系统下备份系统分区或单个/多个文件，由它备份的分区文件可以直接通过变色龙引导启动。
利用SuperDuper！备份系统的优势是它仅复制系统分区里的文件而不是连同空闲空间一起复制，这相对于ghost的备份而已，大大降低了备份文件的大小。


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.
