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.)


That doesn’t mean it’s not encrypted on their servers……
Also doesn’t mean it is. Or in a way where only you can decrypt it.
The chain of custody is unclear either way. You’re not in control.
It’s pretty clear actually - all data is encrypted at rest on their servers. They specifically say so.

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:
It’s not zero-knowledge!
That’s really not an issue though.
Yeah. It’s almost like I literally said that in my second comment.
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.
Strongly disagree.
With what?
That self hosting admins on lemmy probably care about their backups not being accessible to third parties?
I don’t think you can claim that they wouldn’t.
You can claim that YOU don’t mind. But that’s a sample size of one. And I’m not denying there are people who don’t care.
I just don’t think they’re the type to be self-hosting in the first place.
And that still doesn’t answer why the fuck you set out on this series of “well achuallys”?
It seems to me, you’re still looking for something to correct me on.
Define “accessible” here. They’re encrypted ……
Being able to download an encrypted file is not the same as being able to download it and unencrypt it, which they can’t do.
