We have our Windows 2012 server backup set to run at 9:00PM. This machine contains 2 Hyper-V machine, but are not part of the backup.
When the backup kicks on at 9:00PM, the clients accessing the Hyper-V machines are disconnected for 1-minutes, then they can reconnect.
I've verified that the Hyper-V is not part of the backup.
The volume the Hyper-V machines run on are part of the backup though.
Thanks.
