@Andrew
Thank you Andrew
Such a noob here when it comes to XCP, learning as we go.
I couldn't find any guide out there for configuration of CR so was shooting from the hp on how it worked.
You were correct that NBD Connection was not setup on the Pool network.
Since you seem to be an expert in this CR field. Mind if I ask a question.
For the Full backup interval what do you typically set this to?
In our case we have around 4TB of data (Approx 25VMs) we are going to have on CR over a 1Gbps link between locations, so we can't be doing full copies to often.
