Big dilemma: data protection with Knox (sparseimages) / back up with SuperDuper!

[gianfry]

More specifically…

From the manual, page 16:


"With a Sparse Image, your files are kept in a “virtual” disk, which is actually stored in a single file. This file can be placed anywhere, including on a network volume. When mounted (which you do by simply opening the
Sparse Image file), the “virtual” drive looks just like a local disk, and can be
backed up to like any other. You can even Smart Update it!

There are some disadvantages, though:

• …
• …
• Finally, since they’re not physical drives, images of any type cannot be
used to start up your Macintosh. However, the contents retain their
bootable properties and – once restored to a real drive – can act as a
startup drive."

Now, my understanding from that, is that whenever the "Copied HD" is on a sparse image, you can't just reboot once the image is mounted. Is that right?

If so, can you just mount the image and simply copy the "Copied HD" in it to the drive itself (assuming you got enough space for it), so that you can boot from there. (You end up with two exact copied stuff on the same HD, but at the least you can reboot, should it be necessary).

That would mean that you can't possibly have a "password protected" copy of your Mac which is bootable.

Mmm, or am I missing something?
