Cheapest way to back up a lot of data? (pawb.social)

Hello!! Some recent technical problems on my family's NAS gave me a big scare and finally pushed me to figure out a way to back it all up. I'm asking here specifically because I really don't know where to even starts because of the fact I've got just under 50 terabytes worth of data stored in a 7-disk RAID-5 and would prefer to keep it cheap. What are your suggestions?

Edit: thank you for all the suggestions, I'll probably be considering using Backblaze for backups, or perhaps seeing if I can scrounge up old unused disks from people I know. Thank you all again <3

Yeah I'm not OP (and I'm not offering this service to the public) but anything I'm ever hosting for anyone else should be zero-knowledge encrypted. I don't want to be able to know what's in other people's data. THAT makes me uncomfortable. As long as it's encrypted, and I don't have the key, it's just random bits as far as I'm concerned.

I don't care what you use your random bits for. None of my business.
