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

4-bay DAS with a handful of big HDDs in RAIDZ1. Load it up, then store it in your office at work or at a friend or family member's house. Retrieve, update, and scrub somewhere between once every few weeks to once every few months, depending on how often your critical data is changing.
