on the disk—something you should never have to bother with if you
have a bootable duplicate. That's not a serious concern, though, in
that the point of Recovery mode is to give you a way to repair and
restore your Mac if you don't have another bootable disk. However,
recent versions of Carbon Copy Cloner can duplicate the Recovery HD
partition if you so choose—consult the app's documentation for
instructions. (As I write this, the current version of SuperDuper can't
do this trick.)
Set Ownership on the Destination Volume
Check to see that the destination volume does not ignore ownership;
if it does, your duplicate will not be bootable. To check this, select the
destination volume's icon in the Finder and choose File > Get Info.
In the Sharing & Permissions portion of the window, make sure the
checkbox labeled Ignore Ownership On This Volume is
deselected
.
Create a Duplicate with SuperDuper
SuperDuper
has a well-deserved reputation for its ease of use and
reliability. The software costs $27.95; a free version lets you create
duplicates but not update them incrementally. (And let me say that
the incremental update capability is well worth the price!)
To create a duplicate with SuperDuper, follow these steps:
1. Launch SuperDuper.
2. You'll see two pop-up menus at the top of the window (
Figure 14
);
choose the source (your internal disk) from the one on the left and
the destination (the disk or partition set aside for duplicates on your
external disk) from the one on the right.
