At Dress4Win, an operations engineer wants to create a tow-cost solution to remotely archive copies of database backup files. The database files are compressed tar files stored in their current data center. How should he 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, scheduled data transfers from on-premises sources to Cloud Storage, making it ideal for archiving existing database backups. Coldline Storage is a low-cost storage class optimized for data accessed less than once a month, which is suitable for archiving backup files. Using a cron script with gsutil is less robust for large, recurring transfers as it requires managing the script's execution environment and error handling manually. While gsutil can copy files, Transfer Service offers built-in features like retry mechanisms, transfer scheduling, and progress monitoring. Regional Storage is more expensive than Coldline and is intended for frequently accessed data, not for long-term archives.
