# MyAPI Hub on Hugging Face Spaces — single-container sidecar:
# postgres:18-alpine + redis + app + periodic pg_dump → /backup (HF bucket FUSE).
#
# PGDATA lives on Space ephemeral disk (FUSE is unsafe for live DB fsync).
# /backup is a mounted HF bucket; we dump there every BACKUP_INTERVAL_MIN minutes
# and restore on cold boot if PGDATA is empty and latest.sql.gz exists.
