3-2-1, Not 1: Why I Kept MinIO Instead of Going Cloud-Only for Backups
· 5 min read
While hardening disaster recovery on the ktayl-solution information system, a fair question came up: we already mirror backups to Cloudflare R2 — so why keep a MinIO server running on the controller at all? Couldn't we retire it and go cloud-only?
R2's free tier is generous, cloud object storage is durable, and one less service to operate is always appealing. So it's a reasonable instinct. It's also wrong — and about an hour after I talked myself through why, I proved it the hard way by deleting the wrong bucket prefix. This post is that reasoning, and the honest incident that validated it.
