Well, Norman, the problem here is that part of his Pro Apps (Final Cut Pro, etc) framework is damaged, and can't be copied.

Normally, I'd suggest that you try duplicating the file in Finder, which would allow you to see if copying will get around the problem. Unfortunately, since it's in a system folder, it's got special privileges and that makes it hard to copy.

So, that means you have to try using Terminal. The commands to use would be:

cd /System/Library/PrivateFrameworks
sudo ditto -rsrc ProKit.framework ProKit.framework.copy
sudo rm -r ProKit.framework
sudo mv ProKit.framework.copy ProKit.framework

Copy/paste each of those lines separately, pressing return after each if it doesn't happen after the paste. If you're prompted for your password, enter it and press return -- note that it won't be displayed as you type.

If you get any error messages at all, stop the process. If there are no errors, on completion, try the backup again.
