Network Considerations

Before you enable DR protection on the primary VM, consider the following:

You set the recovery time objective (RTO) value based on how long it will take for the DR VM to enter a running state. Because the primary and DR VMs are in different IP subnets, when a failover or migration occurs, the DNS servers need to know about the new IP address. When you are determining the RTO value, you need to be aware of the speed at which the network can propagate the DNS name change to the secondary DNS servers.
An appropriate recovery point objective (RPO) value depends on the network connectivity between the primary VM and DR VM sites, as well as the rate of data being changed between snapshots. Therefore, no minimum RPO value can be guaranteed.
