Raid is exactly as much or as little of a proper backup solution as you configure it to be isnt it?
for anyone afraid of the upfront cost: you don’t need to buy so many expensive hard disk drives to self host a media server like Jellyfin/Plex
RAID arrays add complexity and get expensive very fast while not being a proper backup solution at all, it’s nice to have but not required
on a budget buying a large hard disk drive (12~16 TB is a good sweet spot right now) and later down the road another one as periodic backup solution might be the wiser choice while accumulating your collection of media

Technically speaking, RAID is redundancy not backup. A proper backup is an archived copy of the data stored not stored in the same logical infrastructure as the primary data.
With a RAID you can swap in a new drive if one (or more, depending on your RAID#) drive in your RAID array dies. If enough of your redundancy in a RAID fails, you will lose data.
With a proper backup you can restore the entirety of the RAID array even if the original data has been physically destroyed.

This was actually something i thought newer raid features included and is why asked the question!
Thanks for letting me know, im so far out of being in touch with current technology it makes me sad. But i still find i love listening to people like my brother explain to me the stuff hes always keeping up on that we had used in years gone by. Technology is so cool but its so hard to keep up with if you dont work with it professionally. Or have the time/capacity/talent and disposable money if you lack the ability for self learning.
We live in such a disappointing technologically advanced world of the future.

You just happened to get a reply from a former backup engineer who has had to explain this concept to customers.
Something else in the backup world that gets regularly misused: backups != disaster ecovery.
Disaster recovery is a whole plan of action. Backups can be a part of DR, yes, but I have had way too many companies consider their backups as the totality of their DR.

It basically only protects against hardware failure. It’s not going to protect you from ransomware or even just accidentally clicking delete.

Thanks. I was misunderstanding concepts here in a big way

I just download what I want to watch, watch it, then delete it. I have a 500gb SSD in my Mac, and about 30gb of it is currently taken up by Plex.
