For accessing StoreOnce VTL (Virtual Tape Library) targets from Veeam, the recommended protocol is FC (Fibre Channel). FC provides the high throughput and low latency necessary for backup operations, making it ideal for environments where speed and reliability are critical. StoreOnce VTL supports FC as a primary protocol for integrating with backup applications like Veeam.
