Backup Window Calculator
Enter the amount of data you need to back up and the available backup window. Add planning headroom to estimate the network capacity you should target.
Recommended minimum bandwidth1.667Gbps
Sustained file rate208.3 MB/s
Headroom included20%
Headroom is added to the theoretical requirement to provide planning margin. It does not guarantee a specific real-world completion time.
Example
If 5 TB must be transferred in 8 hours, the theoretical requirement is about 1.389 Gbps. With 20% planning headroom, the target becomes about 1.667 Gbps.
What does headroom cover?
It provides margin for protocol overhead, throughput variation and competing traffic. Storage performance, latency, backup software and remote-service limits can still affect the result.
