How about trying the backups without specifying the interface
parameter in the disklist? I never could get that to work the way
I wanted. I just set dumptypes with different maxdumps numbers for
different systems. My antique boxes with 10Mb EtherNet use
maxdumps 1. My fast systems have maxdumps 2.
Are you doing all the compression on the tape host? That could
grind things to a halt.
