Correct Answer: DThe correct option is 'Periodic backup copy.' This configuration is appropriate because it aligns with the strategy to have backup copies (including those with additional days of retention) at an alternate site. Options like 'File to tape job' and 'File share backup job' don't specifically address the requirement to copy backups to an alternate site. 'File share copy job' is not applicable for unstructured data backups in this context, whereas 'Periodic backup copy' caters to the need for an ongoing backup strategy, ensuring that files are consistently copied and additional retention is managed effectively.
