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?
Cold storage solutions would be cheapest if you don’t need to access it often, if you do then Backblaze b2.
Lastly you could do your own backup (drives sitting at a friends of family’s place?)
