SuperDuper v2.7.5 is here, and it's compatible with Yosemite! ... SuperDuper is the wildly acclaimed program that makes recovery painless, because it makes creating a fully bootable backup painless. Its incredibly clear, friendly interface is understandable, easy to use, and SuperDuper's built-in scheduler makes it trivial to back up automatically. It's the perfect complement to Time Machine, allowing you to store a bootable backup alongside your Time Machine volume—and it runs beautifully on your Mac!I have been relying on Carbon Copy Cloner the last few days, and it has been good to me. It costs $39.99, but there is an academic discount of 25% which brings it down to $29.99. The price of SuperDuper! is 27.99.
The last few wasted days have shown to me that a program like Carbon Copy Cloner or SuperDuper! are absolutely essential. They have also shown to me that Time Machine cannot be relied on. When I needed it most, it did not work. Nor do I know why it did not work. I could get into time machine, but every backup after the present one was greyed out. I know this now: I should have been more circumspect and have trusted Apple products less.
