Whoops, premature send, here is the full version.
Using Acronis, I'll incrementally image the primary hd onto the USB cradled hd.
Then you wouldnt be able to use that USB cradled hd in the laptop
when the original dies, you'd have to buy a new drive for the laptop
and restore those images from the USB cradled hd, and you said
that you dont want to do that.
And in that case the USB cradled hd need not be a laptop drive.
And you dont even need a USB cradled hd either, you can write
those images across the lan to drive space on a desktop PC etc.
There are some cloners that can incrementally clone, particularly xxclone,
but Acronis True Image cant incrementally clone, only incrementally image.
Not clear on you mean with imaging and cloning.
I'm using those terms in the same way Acronis does.
A clone is an exact copy of the original drive, it
has the same partitions, files etc as the original.
And image is a file which contains all Acronis needs to restore
to another drive so that drive is the same state as the original
was, and with incremental images, you get an extra file for
each incremental image you do. They are all used to restore
the new drive to the same state as the original was when the
last incremental image was done.
No way is an external USB drive going to be faster than the internal hard drive.
Correct, altho that isnt necessarily strickly true with
older laptop drives that are normally only 4200 rpm
etc. A USB external drive can be a faster 7200 rpm drive.
So, putting a spare internal hard drive into a USB cradle as a mirror
allows the fastest and easiest setup when the primary drive crashes.
Yes, but Acronis cant do incremental cloning, just incremental images
which involve restoring the images to a replacement drive if the original dies.
What are the reasons to use either imaging or cloning?
Cloning allows much faster use of the clone if the original hard drive dies.
In your config you just have to unplug the USB cable and bridge from the
spare drive and plug the spare drive into the laptop in place of the now
dead original and boot off the replacement drive. It will then perform
just as well as the original drive did.
BUT Acronis True Image cannot do incremental cloning, it can only clone the entire
drive to the spare USB cradled hd. Thats not necessarily a bad thing because laptop
drives arent that big, so a full clone still happens in a reasonable time.
xxclone can do incremental clones, but I'm not sure if it supports external USB cradled hard drives.
Imaging requires restoration of the image(s) and you have said
that you dont want to go that route because you want to be
able to use the spare drive immediately if the original dies.
If you dont really need to do that, you could image to somewhere else,
even the desktop system over the lan etc, and then keep the spare handy
and restore to that if the original laptop drive dies.
You obviously wont be able to do that if you are away
from home with the laptop when the laptop drive dies.
