too slow. at my old desktop with Athlon 64 x2 5200 and 3 SATA II drives
backup of 2.7GB database from one drive to another took from 3.5 to 5
minutes, depending on protocol used.
The fastest way to do backup is to use Services API,
i.e. -se option of gbak. And, to use -g option of course.

So, with worst 5 minutes result, 74/2.7 = 2 hours and 17 minutes.

And, with the a bit modern hardware (but still desktop with several
restore of another database, 1.5GB backup size and 3.9gb
resulting database also takes not more than 5 minutes,
via -se.
But, via localhost - around 1 hour.
