Once you get familiar with the terminology and a few "do's and don't's", you'll find that HDD backups are usually fast and the process is reliable.
I've had 2 Cloning failures out of about 100 with 3 PC's. Those 2 failures were interesting , since I've identified the reason for the 2 failures but not the cause.
I've not yet encountered a failed Image-restoration process although I Clone more frequently than Image on my PC's.
I forgot to mention something earlier about full-HDD backups:
I'd recommend verifying your HDD backup activity once you've decided on your methods.
For example, here's what I did when I decided on my HDD backup tools/software.
I did a complete HDD backup/restore, simulating a "worse-case" scenario where I didn't have a working OS or perhaps my OS HDD failed unexpectedly.
Imaging: After I created my bootable/rescue media, I used a spare unallocated HDD and booted up on the media and did a "restore" using one of my stored full-HDD Images from my external USB storage HDD.
Cloning: I did the same thing, started with a blank HDD, booted up on the media and Cloned to it from my good OS HDD.
That tests the bootup and loading the software tool into RAM. Then I restarted the PC, booting into the newly-Cloned HDD or the Image-restored HDD to verify normal Windows operation.
Once you verify the complete bare-metal HDD recovery methodology, you'll be confident that you've tested your HDD-recovery path.
