Comment on How do you effectively backup your high (20+ TB) local NAS?

  Sure they can. How else do they enable providing access to the content without the user password?

  The data is secured against unauthorized access, but unlike zero-knowledge setups where the chain of custody is fully within user control, the user is not the only one authorized. And even if you are supposed to be, you cannot ensure that you actually are.

  OF-FUCKING-COURSE the physical drives are encrypted. That’s how you prevent unauthorized physical access.

  But encryption is not some kind of magic thing that just automatically means anyone who shouldn’t have access to the data, don’t.

  For that to actually be the case, you need solid opsec and known chain of custody. Ways of doing things that means the data stays encrypted end-to-end.

  The personal backup plan doesn’t have that.

      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 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.

        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.
