I won’t go into my solution here, but the only tip I’ll give you is don’t use cloud based storage. Restoring is slow if we’re talking terrabytes, it’s expensive compared to buying a disk and your data is never truly safe.
Buy another drive, backup to it and have it on a rotation schedule. I keep my “offsite” backup in the boot of my car. If I’m not at home I’m usually away with my car.
