A media company needs to migrate 300 TB of raw video archive files from their on-premises network-attached storage (NAS) facility to a Google Cloud Storage bucket. The facility has a shared 100 Mbps outbound internet uplink that must remain available for daily production operations, and the entire data transfer must be completed within three weeks. Which migration approach should the company implement?

Order a Google Cloud Transfer Appliance, copy the data directly to the appliance over the local network, and ship it back to Google Cloud for ingestion: ### What Transfer Appliance Is **Google Cloud Transfer Appliance** is a ruggedized, high-capacity hardware storage server that Google ships directly to your data center. It is designed specifically for **large-scale offline data migrations** when uploading massive amounts of data over existing network connections is constrained by low bandwidth or tight timelines. ### How It Meets the Requirements - **Data Volume and Bandwidth Limitations**: Transferring **300 TB** over a shared **100 Mbps network connection** would theoretically take nearly **300 days** (assuming 100% sustained utilization), making an online transfer impossible within the three-week window. - **Production Availability**: Transfer Appliance connects locally to your high-speed internal LAN/NFS infrastructure, transferring data at gigabit speeds without consuming any outbound WAN or public internet bandwidth needed for daily operations. - **Time to Completion**: Loading data directly onto the appliance over a local 10 GbE interface takes only a few days, allowing the entire shipping, offloading, and ingestion process into **Cloud Storage** to finish well within three weeks. ### Key Advantages - **High Throughput**: Supports rapid local ingestion via NFS shares and optimized copy tools. - **Data Security**: Includes hardware-level and software-level AES-256 encryption to protect data during transit. - **Zero WAN Impact**: Completely eliminates bandwidth contention across shared internet connections. ### Why This Is Optimal Transfer Appliance is the industry-standard solution for physical bulk data movement where data sizes exceed tens of terabytes and network uplinks cannot support an online transfer within the designated project schedule.
