Thanks.
You asked how to calculate theoretical speed, so that's what I answered.
If you want to know how long it will take, then just do it.
Or you can do what you proposed.

But that is not the reality, is it? It is not possible to write to a harddisk that fast.
So what you are telling me is correct, but I did not ask the right question!
All things considered, the time to backup a 1 Gb of data, depends on the network and the NIC in the servers and the harddisk controllers and the harddisks (and maybe the software). So if the network is 1 Gigabit, the data is not backed up that fast.
I could backup 10 Mb and measure how long it takes, and then correspond that to 1 Gb, do you agree?

Assuming you're getting Gigabit speeds, roughly 8 seconds. 1000 MB/s = 120 MB/s, = 8.3 seconds to transfer a Gigabyte.

On what kind of network?
2 Windows servers, connected via a Dell Gigabit switch.

I would like to calculate how long it takes to backup one Gb of data from one server to another. How do I do that?
