H2 databases support both backup and export operations through built-in SQL commands that work while the database is online. The BACKUP TO command creates a consistent ZIP archive snapshot without stopping the database, avoiding the risks of raw file copying. For exports, CSVWRITE writes query results to CSV files for reporting or data sharing, while SCRIPT generates SQL output that includes schema and data for migrations or test setups. RUNSCRIPT can restore SQL script exports, completing a logical backup-restore loop.
