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

AWS Glacier would be about $200/mo, PLUS bandwidth transfer charges, which would be something like $500. R2 would be about $750/mo

50TB on a Hetzner storage box would be $116/month, with unlimited traffic. It'd have to be split across three storage boxes though, since 20TB is the max per box. 10TB is $24/month and 20TB is $46/month.

They're only available in Germany and Finland, but data transfer from elsewhere in the world would still be faster than AWS Glacier.

Another option with Herzner is a dedicated server. Unfortunately the max storage they let you add is 2 x 22TB SATA HDDs, which would only let you store 22TB of stuff (assuming RAID1), for over double the cost of a 20TB storage box.
