I run a hd>hd clone monthly.......works fine.
It's not a blink of an eye thing but in 4 or 5 mins it's done.

Cloning is ...

where you have a drive and clone it to another drive of the same size which makes the second drive an exact copy of the first drive.

Imaging a drive allows you to create an image file of a drive or partition on another drive where the drive only has to be bigger than the image. This image is not bootable like a cloned drive but it is considerably smaller and allows you to write several image files to the same drive for storage. The image is then used on a new drive should the original drive crash or can be used on the original drive should the drive be hard hit by viruses or other problems.

Clone vs image
Sep 21, 2012 1:09AM PDT

A clone is an exact copy of the orig hd........bootable.
An image is a compressed copy of the orig hd......not bootable.

Pro's and con's to each method.

I use a clone because it's faster.
I have a few spare hd's and rotate the units.
Works for me.
Your call.

I find the image backup to be faster.

The clone job has to duplicate and write empty areas to the target drive so here, the clone takes much longer than an image backup.

Both satisfy slightly different goals.

The last time I tested this.

Image.......a little less than 7 mins.
Clone.......a little more than 5 mins.

Since the amount of data on the hd has grown I'll take a guess.

The image time will have gone up.
The clone time will remain the same.

The op can run their own test to see what's best for them.

Do that all the time.

In my case I boot up Clonezilla and save a new image. Since this is smaller than the clone I can get a few backups on each external. Clonezilla is free but folk that can't select a number off a menu may be challenged.
