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

It's kinda complicated because a good chunk of that is data that is technically redownloadable, but has been tweaked (most of my movies are a multiplexed high-res eng version merged with audio from lower-res dub.) Either way, thank you for the suggestions

I suggest making a script that uses existing software (ie mkvtoolnix) to extract the dubbed audio and then backing that up and l leaving the high quality video to the Web to backup.

I know it's less than ideal but you can automate both extracting it and muxing it back in. It may take some effort to setup, but it's well worth the huge recurring costs incurred from backing up that amount of data.

Just an idea to consider.
