My original problem, was with backing up in an ACTIVE/ACTIVE configuration.
Each node had 2 LAN connections.
One for the Public LAN
One for the MSCS heartbeat.
By putting the public LAN card in the
REQUIRED NETWORK INTERFACE field,
I sorted out my throughput issues.
I will shortly be setting up NBU onto an
ACTIVE/PASSIVE cluster, but I think the same
thing will be required.
