encryption and bootable backups?

I've been using Super Duper for many years on many machines. Just fantastic. But now I'm bolluxed. Tried to set up a SD clone (to a 1 TB USB disk) on a 10.5 MacBook Pro that happens to be (unlike all my other machines) encrypted. This is a work machine that I'm required to encrypt. The clone is made, and SD reports that the volume was made bootable, but it's not. When I do option-restart, the backup volume simply isn't displayed as a boot choice.

I suspect it's all in there, but unless I can boot to that volume, and log in, the encrypted stuff on the clone is completely unavailable to me (which is why the encryption makes it secure!) Also, not having a bootable volume makes it pretty inconvenient as a life-preserver in case of a system disk failure.

What's going on? I'm not sure if this is a SD issue, or a system issue. I'm not even totally convinced that the problem is because of the encryption.

Does it show up in the startup disk preference pane as a boot choice?

Yes, it does.

I should add that this machine is an Intel Core 2, and the USB drive is GUID partitioned.

Can you select it as the startup drive in the startup disk preference pane and do that? Repair it with Disk Utility (right-hand "repair disk" button first).

OK, I did a "Repair" on the USB backup disk with Disk Utility. No problems reported.

Then I selected the backup volume in that disk as the "Startup Disk" in System Preferences on my Mac. Then I rebooted.

Yes! It works. I'm booted on the clone and everything looks, well, like the original.

So what it comes down to is just that option-Restart doesn't want to show me that USB backup volume. Now, I need that to work, of course, because if my laptop disk craters, I need to be able to do option-Restart to boot on the clone. So what's going on? Why can't I do that?

Does it do so now, though? If not, power off, disconnect the drive, get to Option+power on, then attach the drive and see if it does.

I'd recommend making a thumbdrive with the OS installed on it (along with SD) in case you don't have boot media, if the drive is unreliable at Option+power on time.
