It's hard to blame kubernetes as the issue here. The way EKS is implemented, it's basically EC2's running a bunch of containers with a convenient control plane and network interface abstracted over them. If they had used EC2's/VM's, they could have still run into the same issue by blowing away a host's local volume they were never actually backing up. I have administrated social media websites (not this software, mainly discourse) and have seen this exact thing happen. Luckily, the backups worked.
