• Added backups:/backups volume mount to the vectorflow service
• Declared backups named volume with name vectorflow-backups
• Aligns with existing backup service implementation that uses /backups as the default backup directory
• Matches the production docker-compose.yml which already includes this volume
• Follows existing naming conventions and patterns
