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.)

    No shit. But encryption isn’t the same as zero-knowledge. Where by the time they handle the data in any way whatsoever, it’s already encrypted, by you.

    Do you not know what zero-knowledge means? Or are you so focused on my mentioning they’ll ship data to you physically that what I actually said went over your head?

    From the page you just linked:

    1. Implement encryption transparently so users don’t have to deal with it

    2. Allow users to change their password without re-encrypting their data

    3. In business environments, allow IT access to data without the user’s password

    It’s not zero-knowledge!

        Yeah. It’s almost like I literally said that in my second comment.

        Which some people are ok with, but not what most of us would want.

        What gap in my knowledge are you trying to fill here?

        I didn’t even mention encryption in my second comment. Just that their backup plan isn’t zero-knowledge.
