I have a Time Machine drive with 1.13 TB of data on it. The backups go all the way back to 2008. I want to move all this backup data to another drive and keep all that history. Should I use: Carbon Copy Cloner Super Duper Something else? I have done this successfully 3 times in the past. Each of those times, I followed the instructions from Apple. The Apple instructions can be summarized as follows: In the Finder, drag-and-drop Backups.backupdb from the old external hard drive to the new external hard drive. That worked for me 3 times in the past, but it absolutely will not work now. I made a total of 5 attempts to do the Apple-style drag-and-drop. On the fifth attempt, I was fairly hopeful. It spent about 30 hours "Preparing to copy" and then about 27 hours "Copying", but then it just stopped, having only copied 1.00 TB of stuff. So now I think I will try a third-party application. Has anyone successfully used Carbon Copy Cloner or Super Duper to clone a Time Machine drive? Alternatively, does anyone know how to fix the Apple problem where it copies 1.00 TB of stuff instead of all 1.13 TB? I don't really want to go the Apple route, I have spent a long time trying, and the fact that it takes 57 hours to do 90% of the job is fairly intolerable. Both drives are USB 3.0 and my laptop has USB 3.0, copying 1.13 GB of stuff can be done in about 1 hour, I have seen it.
