I was altually thinking of having two seperate jukboxes at two different locations. I am concerned about the trafic casued by network backups. I am pretty sure there are ways to handle this, but I don't know how. > With Amanda's scheduling capability you might even find that a robot is > not really necessary, depending on your total disc usage among all hosts. > E.g.

I don't quite understand how 490GB data can fit in a 70GB DLT tape. How do you do that? You are right, if such a big compression can be achieved, a robot is not necessary al all! Great news! Thanks!
