A data engineering team is setting up a recurring data ingestion pipeline using Google Cloud Storage Transfer Service to sync files from an external object storage bucket to a destination Cloud Storage bucket. The team has the following requirements:
Which configuration settings should the team choose when creating the transfer job?
Set the schedule frequency to Run every day, configure the overwrite condition to If different, and set the deletion option to Delete files from destination if they're not also at source.
Set the schedule frequency to Run every day, configure the overwrite condition to Never, and set the deletion option to Delete file from source after they're transferred.
Set the schedule frequency to Run with custom frequency set to every 30 days, configure the overwrite condition to If different, and set the deletion option to Never.
Set the schedule frequency to Run once, configure the overwrite condition to Always, and set the deletion option to Delete file from source after they're transferred.
Set the schedule frequency to Run every day, configure the overwrite condition to If different, and set the deletion option to Delete files from destination if they're not also at source.
Storage Transfer Service provides granular options to control scheduling, object overwrite rules, and object lifecycle actions during data ingestion jobs. When configuring a transfer between cloud object stores, parameters can be customized in the Google Cloud Console, via the gcloud transfer jobs create command, or programmatically through the REST API.
This configuration cleanly satisfies all functional criteria using native, managed features of Storage Transfer Service. It avoids unnecessary data egress and transfer costs by skipping unchanged files while guaranteeing synchronization consistency by cleaning up orphaned objects.
