The problem I have with such monster capacity HDD is there's no longer any backup media that can viably be used to make a complete backup of the content able to be written to such a drive.

That's why you buy 2.
Or, on some systems, there's ways of combining diskspace over multiple disks to give a greater virtual drive size.

I have been into "IT", started two computer clubs, and built my computers from the 486's will soon be building my sons new gaming machine
I have four 4Tb drives in my PC, and have external WD backups. The way to backup hard drives now are hard drives, use your older ones to make backups,
NEVER put all your eggs in one basket.
These drives are great, IF you have the same size externally NOT internally to backup to, why not internally, because viruses etc can migrate drive to drive when on, external drives should only be on when backing up. IF you have an external drive for daily use separate the backup drive until needed.
My son is a gamer, larger drives are a must for him, but it is like photographers who shoot weddings they set out in the morning with a 512Gb card in their camera and shoot all day, good luck.
I shoot 4 different cards during the day, if one packs up I have not lost everything.

To follow up from Chris,
Windows, Linux, Mac OS X all support RAID arrays.
RAID stands for Redundant Array of Inexpensive Disks.
What is termed a RAID 1 array is where you get two drives that provide
a mirrored set. The same data is written to both, providing redundancy.
If one drive fails, the system keeps running.
There are other levels of RAID that either provide for spanning of data
over two more more disks or for spanning with data with back up
redundancy should a disk fail in the set.
Redundancy through RAID arrays can in some situations circumvent the
need for a dedicated backup or perhaps increase the time period between
backup snapshots.
Most mission critical systems use some form of RAID storage.
In data centres the disks are often "hot swappable".
It's usually easy to set up RAID with commodity disks such as these
on a home computer. Google for your favourite OS.
Good point Jermeny, I heard a story not so long ago that this fellow shot a whole wedding with out a card at all, how he did this is beyond me but apparently it is a true story, boy were they pissed.
You may say well one cant shot without a card as it would come up telling you that there was no card, but actually one can.
Though it is usually of little consequence in the purchasing decision
of the home user, for giant data centres the advertising claim that the
disk shown consumes 58% less power than its 8GB sibling is a major
consideration.
Large data centres like those run by Google are some of the most energy
consuming facilities in the world.
They tended to be sited near sources of hydroelectric power and next to
rivers, such as the Columbia River, where water from the river is
used to cool the data centre and the waste heat is injected back into
the river.
Every time you do a Google search, you often heat up a river somewhere
by another tiny fraction of a degree.

There is a Canon setting - maybe Nikon too - of Shoot Without Card (or something like that) - basically a simulation to check exposures etc, and nothing saved.
I've actually done it myself, and after this embarrassment, turned this option OFF.
For my 28Tb of disks at home, I use Backblaze cloud backup. Between backblaze, and an unlimited data plan, I've dodged a few bullets. Very few of my disks are "young", and so I lose one every 6-8 months. When they go, it's a simple case of replace disk with new, and download offsite backup. This takes about 1 week, or less if I download at work also.
One can encrypt the data on the off-premise storage if needed.
Having some new, shiny, power efficient, and likely faster disks would be a great step up from the rabble I'm running. If I lived down south, the office could double as a central heating unit. No value in Nth QLD however.

I was reading a while back that Iceland is growing a nice datacentre industry, thanks to abundant geothermal power, natural air cooling, and central position between North America and Europe. Good for them

1. DISABLE in the camera the ability to shoot WITHOUT a card,it is there for when you tether the camera to a laptop for studio work.
2. Get Public "indemnity" insurance, NOT Liability, Indemnity insures you against work mistakes
3. When I shoot for a magazine, or other paid work I ALWAYS and only use cameras that have TWO card slots, main and second used as backup.
I divide my work into parts, say, Brands Hatch, if I am shooting five stages I use five cards with five in camera backups.

Most of the mining for bitcoin is done there as the masses of computers get almost limitless free cooling

No, it if for shooting when tethered really and direct to PC/Laptop in studio.
I use Camranger when shooting in studio and turn cards off
Also remember you have green drives, black, red, blue, purple etc...... (Western Digital) Other makes have other designations, I use green and red, my son who is a gamer uses black https://hddmag.com/western-digital-h...ors-explained/
