A hospital wants an automated process to upload new on-premises medical images to Cloud Storage for archival. Which solution should you implement?

The most straightforward and cost-effective solution for transferring on-premises files to Cloud Storage is to use gsutil. The gsutil rsync command efficiently synchronizes local directories with Cloud Storage buckets, only transferring new or changed files. Scheduling this script with cron (on Linux/macOS) or Task Scheduler (on Windows) automates the process. Pub/Sub is a messaging service, not a direct file transfer mechanism; it would require custom application development to send the actual image data. Dataflow is a data processing service, typically used for large-scale transformations, not simple file synchronization. Manually uploading is not an automated solution and is impractical for continuous archival.
