RE: Ransomware the end of the 3-2-1 backup?

I have over 8 terabytes of data I consider important. Mostly digital photos and video going back decades at this point. Even a couple of old home movies from the 1950s when my Mom was a toddler. I make a backup to an external hard drive periodically and even keep another "offsite" though it is just where I work which isn't very far away. The offsite one doesn't get updated as often as it should. But I figure that's about the best I can do for now.
