How much of that 50 terabytes is media downloaded from the Internet? Because the cheapest way would be to trust that it's already backed up on the Internet and then use one of the usual services like B2 by Backblaze or Storagebox by Hetzner to back the rest of it up.
This is a good compromise. When I was tight on backup space, I just had a “backup” script that ran nightly and wrote all the media file names to a text file and pushed that to my backup.
It would mean tons of redownloading if my storage array failed, but it was preferable to spending hundreds of dollars I didn't have on new hardware.
If you tested whether those files had healthy seeds on the Net, that would actually be a pretty cool idea. But I have some rather rare Linux ISOs that definitely don't get seeded anymore so those I would want to not lose and actually backup.
If you back up the modern day Arrs databases then it's essentially the same thing and already built into the software that will redownload them for you. That's my solution. I backup my backups of those, of my home assistant, my Immich library, my Nextcloud, etc... Pirated media is, for the most part, out there backed up on several places already.

But... can we trust that we will have stuff available on the internet in the future?
All my TV shows and movies, I don't bother. But my 150gb mp3 library I keep backed up because it's much smaller and I know some of that stuff is not readily available online.
Exactly. Regimes want to kill this as fast as they can to milk us of every penny witghr their shitty services. I dont trust any sites will stay up.

Yeah, if 90% of that is movies/shows, then you really don't need a backup of that as you can always re-download it. Then you have a 5TB backup problem which is much cheaper to solve.
It's kinda complicated because a good chunk of that is data that is technically redownloadable, but has been tweaked (most of my movies are a multiplexed high-res eng version merged with audio from lower-res dub.) Either way, thank you for the suggestions
I suggest making a script that uses existing software (ie mkvtoolnix) to extract the dubbed audio and then backing that up and l leaving the high quality video to the Web to backup.
I know it's less than ideal but you can automate both extracting it and muxing it back in. It may take some effort to setup, but it's well worth the huge recurring costs incurred from backing up that amount of data.
Just an idea to consider.

First thing is decide what data you have that can be readily replaced. e.g. publicly available Linux ISOs. Then remove that from your backup strategy. You may end up with a lot less data needing backup.
Exactly, you can just redownload them later. But pay attention if you have rare Linux ISOs, maybe because of their quality or if they're in a specific language.
is the best resource for finding cheap personal digital storage, last i looked into it not sure how up-to-date that site is kept though
Tape is still the cheapest and best archival medium. Drives are expensive, but the actual tape is cheap. But 50TB might not be enough to justify.
The tape drive costs more or less 2000€ (without VAT), the tapes cost about 80-100 for a 15tb drive (and compressed capacity doesnt count as the to be backed up data is probably not just a database or text.
Don't think there are much economic options beside finding the cheapest S3 storage or a secondary backup server.
I'm heavily researching tape for my data, I currently sit around 400TBs Total but only around 200 in data that id actually want to backup and can't just redownload.
Iirc the break even point 100-150TB
ETA: that break even point might actually be lower now that I think about it since that number is probably outdated when I did it and doesn't account for the shortage crap
I just came here to say exactly the same thing. Tapes for the long term, but you also have to take reaaaaaly good care of how they’re stored ie. don’t store them under the kitchen sink in your bathroom
My kitchen sink in the kitchen is fine though? What about the bathroom sink?
/s
Tape Drive?
My suggestion: Buy 3x 28TB drives. Mirror the data to them. Then move them off site.
The off-site location could either be a family member's home where you can then sync to the drives over the internet. Or in a PO box nearby that you retrieve them from time to time to re-sync the data.
I would definitely keep them warm, as in a running machine.
Drives on a shelf die more often than always-on drives.

In the backup world, 50TB isn't really a lot, and you're not really ready to talk about tape systems or maintaining an always-on disk system. Also, HDD's have been getting more expensive due to AI idiocy. But, cheapest is probably a second raid system, like 4x 20tb drives. Do the backup at home and then move the backup system off site and either keep it spinning, or make sure to spin up and test the individual drives every so often.
Backblaze personal is about the cheapest I know of: $99 per year unlimited. Caveats would be that the drives have to be physically connected to the computer doing the backup. Additionally, should you ever need to restore the backup, the best way would be to buy a 10 tb drive from Backblaze, restore the data, then send the drive back for a full refund x 5. Restoring 50 tb online would be excruciating.
I'm currently backing up my NAS to Backblaze Personal by mounting the drives using Dokany. They appear as local drives and the Backblaze client accepts them for backup.

But isn't it available only for Windows/macOS?
Yes, however you could run it in Wine, or create a Windows VM.
Nobody said this here but storj is one of the cheapest storage out there and it's has redundancy and is distributed. And if you have truenas, it's kinda baked right in. They had some hiccups when communicating changes to the community, but overall nice folks.

Cold storage solutions would be cheapest if you don't need to access it often, if you do then Backblaze b2.
Lastly you could do your own backup (drives sitting at a friends of family's place?)
First: there is no cheap way to back this amount of data up. AWS Glacier would be about $200/mo, PLUS bandwidth transfer charges, which would be something like $500. R2 would be about $750/mo, no transfer charges. So assume that most companies with some sort of whacky, competing product would be billed by either of these companies with you as a consumer, and you can figure out how this is the baseline of what you'll be getting charged from them.
50TB of what? If it's just readily available stuff you can download again, skip backing that up. Only keep personal effects, and see how much you can reduce this number by.

Is it data you would trust in the hands of random strangers on the internet? If so, I can easily store 50TB for you, as long as it's temporary.
Oh, and I have various storage solutions in various jurisdictions, so if you have any preferences as to places you do NOT want to store it, that's something you need to hilight.
... this is odly nice of you. Sorry, but are you really willing to trust a random internet stranger to store up to 50TB of data on your machines? The data could be literally anything and might put you into trouble 😵💫
No offense, just curiosity
what's the difference to storing it on a company's platform?
sign a thing that says there's nothing illegal in it. done.
Also, encrypt before sending. Plausible deniability is a real thing.
Yeah I'm not OP (and I'm not offering this service to the public) but anything I'm ever hosting for anyone else should be zero-knowledge encrypted. I don't want to be able to know what's in other people's data. THAT makes me uncomfortable. As long as it's encrypted, and I don't have the key, it's just random bits as far as I'm concerned.
I don't care what you use your random bits for. None of my business.

Sort your data into stuff you absolutely need to keep (personal files and such) and stuff you'd be okay with losing (less important files, device backups, downloads you can redownload, etc). Then only back up the former. As for backup medium, ServerPartDeals often has some pretty good deals on storage; they were selling refurbished 12TB drives for $80 a pop a while back.
They haven't been selling anything that cheap since the AI driven hard drive shortage. A refurbished 12TB drive is around $200 now.
