Your company wants to migrate their 10-TB on-premises database export into Cloud Storage. You want to minimize the time it takes to complete this activity, the overall cost, and database load. The bandwidth between the on-premises environment and Google Cloud is 1 Gbps. You want to follow Google-recommended practices. What should you do?

The Data Transfer appliance is the most suitable option for migrating a large 10 TB database export with limited 1 Gbps bandwidth, as it provides an offline data transfer solution that minimizes network impact, database load, and overall transfer time. Developing a Dataflow job would place significant load on the database and be slow due to the limited bandwidth. A commercial ETL solution would also be slow and incur high network costs. Compressing the data and using gsutil -m would still be constrained by the 1 Gbps bandwidth, making the transfer very slow for 10 TB of data, and would also place a load on the database during the transfer.
