How do you effectively backup your high capacity (20+ TB) local NAS? (lemmy.world)

I have a 56 TB local Unraid NAS that is parity protected against single drive failure, and while I think a single drive failing and being parity recovered covers data loss 95% of the time, I'm always concerned about two drives failing or a site-/system-wide disaster that takes out the whole NAS.

For other larger local hosters who are smarter and more prepared, what do you do? Do you sync it off site? How do you deal with cost and bandwidth needs if so? What other backup strategies do you use?

(Sorry if this standard scenario has been discussed - searching didn't turn up anything.)

Where do they provide access to the content without the user password?

...

Explain to me how they couldn't. Without simply stating "it's encrypted".

On the B2 plan you can use open source solutions like Kopia, and literally look at the code, to KNOW that data is encrypted on your system with keys only you have, before Backblaze ever sees it.

Explain to me, how the personal plan using their closed source application achieves the same.

Linking to a page where they say "it's secure" is not sufficient. Elaborate. In detail. To at least an equal extent I already have.

So your whole point is that you shouldn't trust one of the biggest cloud backup companies on the planet when they say that your data is encrypted, with no proof that they're telling lies...........and you're asking me to prove that they're telling the truth?

The onus is on you to prove that they're telling lies, not on me to prove what they say is true.

They say this about computer backup on one of the pages I linked earlier:

Computer Backup Encryption

Data is encrypted on your computer—during transmission and while stored. Block unauthorized users from accessing your data by using a Personal Encryption Key (PEK) or use a 2048-bit public/private key to secure a symmetric AES-128 key. Data is transferred via HTTPS. Enhance your protection with two-factor verification via a TOTP (Time-based One Time Password).

Is that all a lie? Based on what?

No.

I'm saying 99.999999999999999999999999999999999999999999999999999999% ≠ 100%

For some people that's close enough. For some of us it's not.

Prove otherwise. I dare you. I'm done putting in effort explaining the obvius to you. Your turn.

So being encrypted before transmission and at rest isn't enough simply because someone at backblaze can send the encrypted files out to you on a HDD........

lol

Nice ragebait.

If you genuinely still think that was my point in its entirety, you are truly obtuse.
