★ SuperDuper: Create bootable hard drive clones, duplicates, and backups for Mac OSX

Posted on July 07, 2011


Hard Disk Clone and Duplicator


I ordered a new SSD (6g from OWC), and I needed a way to mirror my data from one drive to the next. I am running OSX Lion (GM), so that may be why I initially had so many problems.

I tried a few utilities to accomplish the disk cloning process, including Apple's Disk Utility, Carbon Copy Cloner and SuperDuper.

First up, Apple's Disk Utility kept failing, stating an “Input/Output Error”. I couldn't figure out why, so I moved on.

Next up was Carbon Copy Cloner; that didn't work out well, either. The process would start, but the app kept giving me permission errors, specifically around any of the MacPort files and the system logs.

Finally, there was SuperDuper. I was initially turned away by SuperDuper because it was telling me that the copy speeds were only 4mb/s. This may just be during the first minute or so, because I let it sit for a few minutes and then watched the speed jump to 30mb/s. It probably would have been faster if the O/S wasn't running, but everything ultimately worked great. The data was successfully copied, and the drive was made bootable. SuperDuper also included a nice option to check and repair existing disk permissions prior to the start of the cloning process.

SuperDuper is free, but it also has a paid upgrade if you want to schedule syncs/backups.
