An operations engineer needs a low-cost solution to archive compressed database backups from the current data center to Google Cloud. How should they proceed?

The correct solution is to create a Cloud Storage Transfer Service job to copy the files to a Coldline Storage bucket. Cloud Storage Transfer Service is designed for large-scale data transfers from various sources, including on-premises, making it efficient and reliable for this use case. Coldline Storage is a low-cost storage class optimized for data accessed less than once a month, which is ideal for archiving database backups. Using a cron script with gsutil is less robust for large, recurring transfers compared to Transfer Service, which offers features like scheduling, transfer monitoring, and retry mechanisms. Regional Storage is more expensive than Coldline and is meant for frequently accessed data, not for long-term archives.
