If you want to make complete clones of any drive, providing it is for backup purposes even Microsoft are quite happy with that.
For information I use a program called Macrium Reflect free and have always got two spare hard drives with clones on them of my entire system, created with the cloning side of Macrium Reflect.
The beauty of a clone on a drive is that should anything go wrong with the main drive, a screwdriver is all you need to pull out the duff drive and fit the clone drive. Half an hour maximum and your back up and running again. Much quicker than messing about with images on a portable drive.

Read about and download Macrium Reflect here :-

Be warned that if you use the C.Net download link, be very careful to check for and remove the usual unwanted junkware. If offered a choice of advanced or custom installation, then use it, as it is in the advanced or custom install that you will find the junk, and the tick boxes to prevent the junk from installing.

I hope it is OK on here to say that if interested I wrote a full tutorial on using Macrium Reflect to create a clone on the Free PC Help website magazine page here :-
