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

If you back up the modern day Arrs databases then it's essentially the same thing and already built into the software that will redownload them for you. That's my solution. I backup my backups of those, of my home assistant, my Immich library, my Nextcloud, etc... Pirated media is, for the most part, out there backed up on several places already.

This is what I do - well, I back up there entire container. But functionally the same.

There's only a few pieces of media that I have backed up manually due to their rarity, but even those I don't really care about.
