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

I'm heavily researching tape for my data, I currently sit around 400TBs Total but only around 200 in data that id actually want to backup and can't just redownload.

Iirc the break even point 100-150TB

ETA: that break even point might actually be lower now that I think about it since that number is probably outdated when I did it and doesn't account for the shortage crap
