> Software RAID, to avoid data loss due to drive failure

Ok it's old but: raid is not backup.

I've personally worked for a small online shop that was selling digital items and shut down when their raid failed. Of course, they had ignored my warnings to build a mirror system or do copies on removable drives or ... anything resembling an actual backup.

Edit: that said, I do have a box that's pretty similar to what you're describing.

Yes, for actual backups I have M-DISC BluRays [0] which I keep in a fireproof box. They're limited in capacity compared to the full NAS, but big enough for really important stuff like photos and scanned documents (which conveniently are intrinsically write-once).

encrypted, deduplicated offsite backups are another approach. borgbackup on free tier cloud services can be useful for this.

Serious question: are there free tier cloud services with enough storage to be worthwhile?

It probably depends on how much you need to store. But if you need ongoing backup that will get larger and larger then the answer is probably "No".

I back up my family photos and other important files to Amazon S3 using Restic. My 150GB of data ends up costing me about $1.50/month. I could get the price down lower if I use, say, the Infrequent Access storage tier, but at that price point I just can't be bothered to deal with it.

A free tier often isn't worth it if you have to put any time into thinking about whether you'll exceed the limit. I'd just go with a cheap pay-as-you-go service and not worry about it.
