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.)

    Recently helped someone get set up with backblaze B2 using Kopia, which turned out fairly affordable. It compresses and de-duplicates leading to very little storage use, and it encrypts so that Backblaze can’t read the data.

    Kopia connects to it directly. To restore, you just install Kopia again and enter the same connection credentials to access the backup repository.

    My personal solution is a second NAS off-site, which periodically wakes up and connects to mine via VPN, during that window Kopia is set to update my backups.

    Kopia figures out what parts of the filesystem has changed very quickly, and only those changes are transferred over during each update.

      The Backblaze option is something I’ve seriously considered.

      Any reason this person didn’t go with the $99/year personal backup plan? It says “unlimited” and it is for my household only, but maybe I’m missing something about how difficult it is to setup on Unraid or other NAS software. B2’s $6/TB/mo rate would put me at $150/mo which is not great.

        You can’t use the $99/year plan for that. The authorized client only works as a desktop application on Windows and MacOS.

        They only needed about 500GB.

        And personal is for desktop systems. You have to use Backblazes macOS/Windows desktop application, and the setup is not zero-knowledge on Backblazes part. They literally advertise being able to ship you your files on a physical device if need be.

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