The problem with Amanda, IIRC, unless it has been fixed recently, is
that Amanda does not support multi-volume dumps. This is a shortcoming
which needs to be addressed if it hasn't already.
I also see this problem with every program using "its own network
protocols". Why not make use of components which already exist?
Also, dump/restore's complexity also does not increase as the number
of clients increases, really. It just means finding a way of doing
it for the systems (which, granted, Amanda does attempt to solve).
