Hello All,

After getting some cheap 6TB drives from eBay I'm looking to reconfigure my storage setup.

Working from the 3-2-1 rule of 3 copies, 2 media, 1 offsite. I currently look like this:

1.5-1-0.5 (0.5 being a partial data copy, usually just the important stuff)

and am planning to go to:

3-1-1

Everything to date is stored on spinning disks, which is where I'm struggling to figure out if it's even worth a second media type if there's enough resilience in the spinning disks...

What are you all using for the second media type? cloud/tape/DVD or something different?
