I have a Windows failover cluster and every time I take a remote robocopy backup from this cluster it seems like it's causing such high network saturation that the cluster monitor thinks the NIC is unresponsive and then fails over.
This is my assumption based on the time of day this usually happens.
I've tried adding the /IPG flag to robocopy to allow some space between packets. Is there anything else I could consider to space traffic out? I've had similar problems that aren't robocopy related. Perhaps a network interface tweak?
