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

But... can we trust that we will have stuff available on the internet in the future?

    You can replicate across more than one provider and do automated regular monitoring that backups are still accessible.

    If one goes down you hopefully have time to figure out a replacment before the other(s) do.

    Probably not worth it for a bunch of xvid dvdrips or historical archives of full system-level backups but for critical data it's sensible.
