I have 3 of these.

Multiple replication is the key. I make images of my C drive using Acronis True Image, put them on the WD drives. Then I used Beyond Compare to sync my storage drive to the WD. I rotate one drive to Ashley who lives 250 miles away, and I switch back and forth between the other 2 drives using Beyond Compare. Also have clone drives in my case. So that's 4 copies of my storage drive using BC, along with images.
I love the way everyone talks about Raid but barely anyone actually does it. Raid is not the answer, a bunch of backups is.
1. Clone your SSD to a standard hard drive using Acronis True Image, then unplug that drive.
2. Clone your storage drive to a similar drive using Beyond Compare, then unplug that drive.
Now you have clone drives sitting in your case unplugged and the Ransom virus can't get to them.
3. Make images of your C drive using Acronis True Image and put them on the WD 2 TB drives.
4. Use Beyond Compare to copy your storage drive to the WD drive, rotating between 3 WD drives each time.
I've done restores using Acronis and it works. With Beyond Compare, I use the Sync to Right command, copying all the folders to the WD drive. You can exclude directories, and tell it which directories to back up. I run the program, it tells me which files have changed, I push the Sync button, and it works.
