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.)

    A time limit after disasters would be necessary. It’s difficult to think of a proper time limit though, as even a month might not be enough time if your entire house burns down.

    and also accounting for low bandwidth connections… whats more, some shitty providers even have monthly data caps

    Maybe a payment system could be set up to where, if your server doesn’t ping for a week, your credit card is automatically charged (after pinging you with many emails).

    yeah, that would be almost a necessary feature. being able to hold on to the backup when you really can’t restore.
