Ah, thanks. Yeah I was confused because in his long list of vendors he didn't mention Wasabi, Backblaze etc. It appears that I do not know the context of his post.

I’ve never had an issue with Backblaze. I mirror my buckets to iDrive who, so far, have also been perfectly fine.

or cloudflare R2 for that matter (very useful for egress-heavy workloads for which it is ~free)

or Tigris
