The different partitions that exist--
so we have physical partitions would actually
be a system partition, which is going to store the bootloader,
and the data partition, which is going to store
all your user-created files.
If you are taking notes, now is a good time to write down,
even if you get a physical extraction,
you are not getting access to encrypted unallocated space.
There is nothing to decrypt that.
If you get an advance logical extraction or full file
system, what you're going to see is
that you have the iOS device partition that
typically will be named whatever the person is
calling that device.
So if I call my phone Heather Mahalik's iPhone,
it would be called Heather Mahalik's iPhone.
If it Hank's iPad, whatever device you're looking at,
that's what it will be called.
If you have an advanced logical, you will also see a TarArchive.
This is going to contain all the files that
are created in that backup.
Make sure you encrypt that extraction.
