Improving my backup game

[Elarion]

I currently have a desktop PC that has everything on it. Roughly 3TB of pictures and video from both my wife and my lives (we value this a lot), about 21TB of media that I converted over from our colossal library of CDs and DVDs a few years ago, and a lot of documents and projects that are quite a bit smaller.

 

Before, I used to just back up everything to OneDrive as well as two external hard drives. Now, that amount vastly outstrips the amount of storage I have in OneDrive. I was thinking about building a NAS so I could set up either RAID 1 or RAID 5 to protect all of that data. Either that, or getting BackBlaze for 7/month, though I despise subscriptions. I still back up my most important stuff to external hard drives, but now I have far more to manage. What are some good options here?

I get the hate for subscription services, but having an offsite backup for stuff you really care about is pretty important, and backblaze seems to be one of the better options out there
