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

AWS Glacier would be about $200/mo, PLUS bandwidth transfer charges, which would be something like $500. R2 would be about $750/mo

50TB on a Hetzner storage box would be $116/month, with unlimited traffic. It'd have to be split across three storage boxes though, since 20TB is the max per box. 10TB is $24/month and 20TB is $46/month.

They're only available in Germany and Finland, but data transfer from elsewhere in the world would still be faster than AWS Glacier.

Another option with Herzner is a dedicated server. Unfortunately the max storage they let you add is 2 x 22TB SATA HDDs, which would only let you store 22TB of stuff (assuming RAID1), for over double the cost of a 20TB storage box.

    You can have more than 2x 22tb, the SX line is full of storage servers!

    SX65 2x 1TB nvme 4x 22tb (~104€ 0%VAT) SX135 2x 2tb nvme 8x 22tb (~204€ 0%VAT) SX295 2x 8tb nvme 14x 22tb (~384 0%VAT)

    If you manually add the disks to configurations like AX-line, there is a limit, that may be bypassed if you contact hetzners support, but that'd be expensive compared to the SX line I reckon.

    Also, Hetzner's server auction has quite affordable 4x 16tb servers, starting from 63€ 0%VAT, that'd be pretty affordable RAID1- solution, ~1€ per TB/month.

    Unlimited traffic on all of the above, and a sidenote: SX line servers have one-off setup fees, server auction has no setup fees.

    Oops, I didn't know about the SX line, and didn't know they had auction servers with large amounts of disk space. Thanks!! I'm not familiar with all of Hetzner'a products.

    For pure file storage (ie you're only using SFTP, Borgbackup, restic, NFS, Samba, etc) I still think the storage boxes are a good deal, as you don't have to worry about server maintenance (since it's a shared environment). I'm not sure if supports encryption though, which is probably where a dedicated server would be useful.
