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

First thing is decide what data you have that can be readily replaced. e.g. publicly available Linux ISOs. Then remove that from your backup strategy. You may end up with a lot less data needing backup.

Exactly, you can just redownload them later. But pay attention if you have rare Linux ISOs, maybe because of their quality or if they're in a specific language.
