Backup

Back up these Docker volumes:

• etcd-data, minio-data, and milvus-data for the Milvus collection;
• icml-index for current.json and build checkpoints;
• icml-state for sessions, limits, and the embedding cache.

Stop the MCP application before backing up icml-state. For a consistent Milvus backup, stop Milvus, etcd, and MinIO together or use a Milvus-supported backup procedure. Restore all three Milvus volumes as one set, then restore the manifest and runtime-state volumes.
