What a coincidence. I just ran into this issue as well and as wjones states, Carbon Copy Cloner has gotten around the issue for now at least. It's a result of Apple's security methods and APPEARs as though Apple will have to make some changes to their system for bootable cloning as we know it may longer be possible. That said, I was able to make a backup of the Data portion of my drive with Carbon Copy Cloner. It's a bit of a pain but it was successful.
ncralph, good to know. Thanks for the response.
