I managed to get things working on limiting the files I want in a given set,

been able to garner via Google, the machine, a Sun Ultra 5, appears to suffer
a design defect that if the network interface is under heavy load, the
interface will shut down, then shortly thereafter, it'll come back online.
Our NetSaint server will sometimes send (false) notifications showing that
the server machine is down then back up.
Any ideas on how to get AMANDA to take it easy when sending data to the
backup server? I'd rather do it at the application layer if possible.
I don't think there's a way of doing this with Amanda. The network
bandwidth settings don't control the bandwidth used by backups once
they're started, they just stop more backups being started until bandwidth
has been freed up.
THe real solution to your problem is to fix the hardware. We had the same
issues with some Ultra5s being used as file servers (it's just some
revisions of the system board). Find a supported PCI network card and use
that instead of the on-board interface.
