Backyard Data Backup

[Granticus]

So I was wanting to do a physical data backup setup buried in my backyard. I had this idea like a decade ago but never really thought much of it until recently. initially I had considered just creating a "secret box" and dropping a physical backup that was updated ever-so-often. Wifi might not be a good idea as you still need to send power to it, and the wireless setup still "potentially" leaves it open, I have considered going a hardlined power/ethernet connection to a small drive box for up-to-date backups.. 

 

My questions are:

With the subsoil keeping the box (whichever I choose) at a more constant temperature, how could one manage heat in an airtight box buried 2-6 feet below ground. I chose this depth due to possible fires/earthquake or subtle lava flows.

What should the container be made from?  plastic for longevity?  or metal for its heat management/radiation protection

How would i deliver power/ethernet into the seal box without possible moisture breaches.

 

any ideas helps!

I would definitely recommend a metal outside, since that protects it from emp's. you should take something that is as low power consumption as possible such as a raspberry pi or a Nas. use ssd's in stead of hdd's because ssd's are not sensitive to shocks from earthquakes. What i would do to seal it up is to take a salable plastic box, drill a few holes in it for wires and then seal the holes with silicon kit after the wires have been put trough it. And then put the plastic box inside the metal outside.

moisture is my largest concern, but true sealing creates heat exchange issues. unless you somehow heatsinked it directly into the ground.

put box in ground

air tubes to another box that has a dehumidifier function that is exposed to air one in and one out. without this you WILL over heat no matter what unless the box is 8x8x8 feet and greater than 10 feet below surface

you are right that you need a hardline with power over ethernet.

actually you could just water cool the thing with a above ground RAD
