I think you’re missing a link?

Just saw your edit - sounds like you’re recommending instead of having one 4 bay NAS, to have 2x 2 bay NAS’s to back each other up?

Hey thanks for the warning about the redundancy != backup - that is part of the plan in the future to build a smaller NAS off site, or even move this particular NAS off site if I find a willing host. Good point too about the wrong 2 drives failing stuffing the whole thing up. The process you’re describing does sound doable but complicated. Is there any alternative setup you might recommend, or is that it if I go with RAID?

Ah JBOD is new to me, I’ll have to look into it. Is there a free or FOSS recommended alternative to UnRAID?
