RAID doesn't cover all of the scenarios as offsite backup, such as massive electrical power surge, fire, flood, theft or other things causing total destruction of the RAID array. Ideally you'd want a setup that has local storage redundancy in some form of RAID and offsite backup.
for the home user backing up their own data, I honestly think that raid has limited utility. If I have 3 disks to devote to backup, I'd rather have 1 local copy and two remote copies, vs 1 local copy with RAID and 1 remote copy without.

Good lord it even supports BorgBackup. Thank you very much!
US -> DE latency hurts though. I used them when I was in europe but migrated away after I came stateside. Not a problem for cold-storage/batch jobs of course.

For essential personal data you're right, but a very common use case for a home NAS is a media server. The library is usually non-essential data - annoying to lose, but not critical. Combined with its large size, it's usually hard to justify a full offsite backup. RAID offers a cost-effective way to give it some protection, when the alternative is nothing
Having to restore my media server without a backup would cost me around a dozen hours of my time. 2 bucks a month to back up to Glacier with rclone’s crypt backend is easily worth it.
Standard S3 is $23/TB/mo. Backblaze B2 is $6/TB/mo. S3 Glacier Instant or Flexible Retrieval is about $4/TB/mo. S3 Glacier Deep Archive is about $1/TB/mo.
I take it you have ~2TB in deep archive? I have 5TB in Backblaze and I've been meaning to prune it way down.
Edit: these are raw storage costs and I neglected transfer. Very curious as my sibling comment mentioned it.
It's not a best practice, but the last 10 years I've run my home server with a smaller faster drive for the OS and a single larger disk for bulk storage that I choose using Backblaze Drive Stats. None of have failed yet (fingers-crossed). I really trust their methodology and it's an extremely valuable resource for me as a consumer. My most recent drive is a WDC WUH722222ALE6L4 22TiB, and looking at the stats (albeit…

Based on the data, it seems they have 4.4 petabytes of storage under management. Neat. https://docs.google.com/spreadsheets/d/1E4MS84SbSwWILVPAgeIi...
Nowadays you can get a petabyte in a single machine (50 drives 20TB each).

It's not the backing up part that's expensive.
I would not be surprised if you decided to spend the dozen hours of your time after all.

hopefully you have 2x of these drives in some kind of raid mirror such that if one fails, you can simply replace it and re-mirror. not having something like this is risky.
