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

This is a good compromise. When I was tight on backup space, I just had a “backup” script that ran nightly and wrote all the media file names to a text file and pushed that to my backup.

It would mean tons of redownloading if my storage array failed, but it was preferable to spending hundreds of dollars I didn't have on new hardware.

    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.

    If you tested whether those files had healthy seeds on the Net, that would actually be a pretty cool idea. But I have some rather rare Linux ISOs that definitely don't get seeded anymore so those I would want to not lose and actually backup.
