ADR-0001: A Kopia-Native Backup Operator for Kubernetes

• Status: Proposed
• Date: 2026-05-24
• Inspired by: backube/volsync and the kopia fork perfectra1n/volsync (especially PR backube/volsync#1723 and the trigger-redesign proposal backube/volsync#1559). The triggering model also draws on CloudNativePG (Cluster / ScheduledBackup / Backup) and Tekton (Task / TaskRun).

Scope: this ADR covers CRD shape, user experience, and high-level design choices. It deliberately does not specify Go package layout, controller-runtime indexes, leader-election lease IDs, the cron library, or other implementation mechanics — those belong to follow-up ADRs once the API surface is agreed.
