Agreed. While the *arrs are "easy" to set up once you have good knowledge of Kubernetes or at least Docker Compose, that's not exactly common. If you're using the native Windows clients, there's a pretty good chance you don't have a NAS set up (or at least not well), which means there's a decent chance you'll eventually have a hardware failure, and then be surprised when your media is suddenly gone.

ZFS pools with full backups, redundant hardware, and highly available servers is not normal.
