No Stupid Questions

1. Encrypt your data.
2. Make a disk image.
3. Make a torrent of that image.
4. Start a cult where the torrenting your data determines the ranking within the order.
5. Come up with a cool name and logo for the cult. Maybe something like "The Archivists of Eternity" for example.
6. ???
7. Profit

Lawyer, friends/family, cloud storage, or safety deposit box all seem like viable normal options.

To be extra safe. 6 hard drives (each with a copy of the files, and four stacks of Blu-ray disks (each with a copy of the files). Divide these into at least two yeti coolers (include a large silica gel pack just in case), and bury the coolers as deep as possible in the woods.

1-5Tb isn't that much info. I would store it on several different hard drives and have them kept in storage at law firms or bank deposit boxes. Maybe compress and encrypt it into a torrent so it gets preserved on some seed boxes.

In terms of data, put TailsOS on a USB drive, configure persistent storage, download VeraCrypt over TOR, install that, encrypt everything tutorial

What you do with the drive (or drives if you make copies) really depends. If the climate is very wet and warm where you live then storing them outside is going to need very good protection to keep them relatively cool and dry. You'd also have to find somewhere that you can absolutely guarantee isn't going to get redeveloped or otherwise built on, or conversely, knocked down/demolished for as long as you're away.

A long term self-storage company might be an idea, or a bank vault, where you've paid for (for example) 10 years in advance. Of course that means you have to be absolutely sure the company won't go bankrupt or be seized by the corrupt regime you're hiding the data from. You'd also have to have someone else set these up in their name or it could be seized along with you. You then have to hope they don't get seized, or get dementia or die.

If you have comrades abroad in a safer country, maybe physically mail them the drives before the corrupt regime starts noticing you? Then of course you also have to hope they can return them and haven;t forgotten, died etc.

Ten 2TB drives of different brands, wrapped up and glued into aitight containers. Hide sone in the woods, some at friends places if possible, and two in a bank vault (people had that back in the day, a sort of coffer in the bank, I don't know if it exists any more). Two in a car that you put in a long time parking.

Fun excercise :-)

Encrypted, written to LTO, vacuum sealed and buried somewhere temperate.

Depends on budget and storage options

That’s not much data

Listed in order:

Encrypted nas. For that small amount of data raid 1. A shitty e waste pc would suffice. A ups would be ideal. This is least ideal honestly as it requires power, a maintainer, and isnt truly backup

SSD of some kind, even a usb stick Enterprise hard drive like wd gold or ironwolf pro Redundant copies, 2-3 ideally, store in various cool dry locations

LTO tape - far more resilient than hard drives and cost effective per tb but downside is that you need a very expensive ($3-5000) tape drive to utilize them, also very slow to read/write, older/cheaper tape formats (I believe pre lto8?) don’t have the ability to act as an external disk where you can just drag and drop files and are more of a pain to use

Blu-ray M-DISK. Upside for these are that they are very resilient, can be stored basically anywhere assuming you put them in a sealed container, and will last many many years (probably longer than you’ll be alive). Downside is that storage per disk is very low (100gb), cost per disk is high, and write speed is low. so you will need ~ 50 for 5tb of data, each disk is about $25 (so $1225 though tbf there’s probably bulk pricing) and it would take 37.5 hours to burn them. But this would be the most resilient of all

Cloud storage - backblaze, tresorit, icedrive, etc

Hybrid solution - ideal scenario. Load a hard drive or two and lock them away somewhere. If you have access to a Blu-ray burner maybe burn a handful of m-disks of your most critical data (not all 5tb but the most important 1-200gb or so). If you can access a tape drive do that too. Ideally update the tape and hard drives monthly. Update the Blu-ray as needed. local nas and cloud for daily backups

Obviously encrypt your files. Veracrypt is a good solution in a political dissident situation - can create hidden volumes so that if you are caught you can give up passwords and reveal only the outer volume, keeping the inner volume hidden

Context plays a huge factor here. Depends a lot on which country you're being prosecuted, how much effort is people putting in catching you and gathering your evidence, and what kind of resources you can count with.

Personally, I'm not too tech savvy so I'd take the bury it in the woods option even if you say it can get corroded. There's many things that can happen to it, depending on the weather, environmental policies (cross your fingers they won't be selling the land for development while you're away), and what you can afford to store your drives in. I believe it's possible to protect the cache well enough if you ziplock them carefully and then find a Tupperware container, perhaps put that inside a larger wooden box or a tin to protect against crushing you should be good. Hell you can even cover the Tupperware containers in cement so it would look like you are burying rocks. But, do you have access to these things? Do you have the time?

Another option is to hide the cache similarly protected in some architectural nook you know of, perhaps at a friend or relative's house- some places have space under houses. Or perhaps you know how to crawl in some wall space or similar. The challenge here is returning to it, because the landlord (your friend) may be gone, dead or else by the time you're out. The property may be bulldozed and sold, who knows.

Encrypt it and upload it to multiple public places. Archive.org, github, etc.

Something like paperback and multiple copies distributed around the world

Encrypted and RAID 0, all disked stored in different locations, two copies of all disks.
