Started the backup, and waited until it was finish, and then took the
mb/time so its not arcurate, but its still way to slow for a 100 =
Mbit/sec
network... Mostly big files on 10-50 mb.

If the server does some bit manipulation, how come its not using 100% of =
the
cpu?

Maybe a thing to add to the documentation, is that it runs on port 2201 =
i
think it is.
