Explanation

MTU (Maximum Transmission Unit) defines the largest packet size that can be sent over the network without fragmentation. Increasing the MTU allows larger packets (e.g., jumbo frames), which can reduce overhead and improve throughput, especially for large file transfers like QoS prioritizes traffic types but doesn't improve file transfer speed directly. SDN (Software- Defined Networking) is an architectural approach, not a simple change. VXLAN is used for network virtualization, not backup performance. TTL (Time To Live) limits packet lifespan but doesn't affect transfer speed. Changing the MTU can significantly decrease backup times by enabling more efficient data
