Multi-layered.
- Important stuff primarily lives in commercial cloud storage. All of that is also mirrored on the NAS.
- Everything from the NAS SSDs is dumped to the HDDs every 3 days. Both use MergeFS, so if any one drive dies (or both SSDs, or both HDDs), I can replace it and still have a copy of everything.
The entire NAS is also occasionally dumped to an external HDD that's stored at my parents' place. So basically, if the NAS breaks catastrophically, I am at risk of losing some recent stuff that hasn't been dumped there yet, but nothing of actual importance.
