Source ports from the TronoSfera/backupy-cloud monorepo:
- apps/agent/ — Go agent (WSS client, persistent queue, Docker
discovery, 5 DB drivers: PG/MySQL/Mongo/Redis/SQLite,
pre/post hooks, Prometheus metrics)
- apps/backupy-decrypt/ — standalone CLI for client-side decryption
- packages/proto/ — protobuf wire format (generated .pb.go committed
so the repo builds without protoc)
- docs/ — agent spec + wire-protocol contract
