Why doesn't CCC say that the destination volume will be bootable?
I have emailed Mike at CCC about making a CCC clone bootable, but in three attempts, I received no straight answer. This info from CCC 3.4 may clear up why Mike refused to offer a straight answer.
(Does anyone have this same situation? What do you plan to do about maintaining Snow Leopard when you switch to Lion?)
CCC 3.3.7 would make an affirmative statement that "This volume will be bootable" (or not) after you had selected a source and destination volume. CCC 3.4 no longer makes that affirmative statement about bootability. Rather, CCC indicates in the "What is going to happen" description of your task that "If you are backing up an installation of Mac OS X, CCC will make every effort to make the destination volume bootable."
Unfortunately, there are hardware matters beyond CCC's detection and control that influence bootability, and this can lead to a lot of frustration. Western Digital, for example, has a line of hard drive enclosures that can't boot a Mac. Everything about the device appears, from CCC's perspective, perfectly fine. CCC performs perfectly in copying a fully operational OS to that disk, blesses the system, rebuilds cache files -- everything that is required to make the OS installation bootable. It doesn't work though, because those enclosures are not capable of booting a Mac. There are plenty of other hardware-related issues that interfere with the booting of Mac OS X, so I decided that it was inappropriate to make that statement.
That's not to say that CCC says nothing about bootability, though. If there is something about your configuration that would negatively affect bootability, CCC will let you know. When there are configuration concerns, CCC places a yellow caution icon next to the "Customize these settings" button. You can click on that icon to view the concerns, and CCC will also present these to you when you click the Clone button. If you don't see any concerns, and the destination volume has an OS on it when the backup task is completed, and barring any hardware problems that might interfere, your backup volume *should* be bootable.
