I use StableBit Drivepool to make logical storage pools out of groups of smaller HDs. I use 3 and 4 TB drives, since they are cheap, and pool 4 or more of them together to make one pool. For redundancy, I have 4 machines with pools set up with pools big enough to store my entire 10tb media library. To keep them all synced, I use SyncbackSE.
This is the system I settled on years ago, and it works for me. I understand that not everyone has spare machines they can throw half a dozen hard drives into, but I do, so that is what I do.

For backup I use Create Synchronicity, which hasn't been updated in ten years because it just works.
