There's a fan community? I was always under the impression that his videos served as glorified ads for consumer tech. The technical insight delivered was skin deep. Didn't he brag about a 20 drive NAS one week only to cry about the raid0 config dying and taking down a lot of their footage the next week?
I don't think it was Raid 0 if you're talking about the time a long time ago they nearly lost data. If I recall correctly, the data was in Raid 6, but there was no external backup.
I'm not sure if you're referring to https://www.youtube.com/watch?v=gSrnXgAmK8k ("All of our data is gone"), but in any case, I've heard references to ZFS in later videos so yeah, the situation's probably not quite that insane now.
That video is technically hilarious though, it TL;DRs as "download Ubuntu-based USB image provided random RAID recovery company, boot USB and provide said company headless SSH to broken system"... at one point in the video I remember Linus talks to another recovery company about the process and the guy pretty much went "...O.o..." which IMO sums my own opinion up, lol
