I Built My Own Offsite 3-2-1 Backup System

I set out to build a real 3-2-1 backup system for my homelab… and it turned into a way bigger project than expected. What started as offsite backup for 30TB of data ended with a second TrueNAS server, a full NAS rebuild, and a third backup copy with a much simpler restore experience.
