Veeam backup and replication

You can create VM replicas with Veeam Backup & Replication. When you replicate a VM, Veeam Backup & Replication creates an exact copy of the VM in the native VMware vSphere format on a spare host and maintains this copy in sync with the original VM.

IP address assignment 

If you use different network and IP schemes in production and DR sites, in the common case you would need to change the network configuration of a VM replica before you fail over to it.
