CBT tracks the disk block changes made by the source VM. When enabled on the source host, CBT records the blocks that have changed since the last replication pass and transfers them to the target host without scanning the VMDK. CBT only identifies these disk-sector changes when VMware® ESXi™ version 5.0 or later is installed on both of the hosts being used for replication.
NOTE: CBT must be enabled for each VM that you want to replicate. VMware vSphere® supports CBT, and most VMs running in this environment can use it.

Replication transport actions occur through HotAdd — LAN-free or network. If one transport method is not available, vRanger attempts to perform the replication task using one of the other transport methods. You may configure the order in which vRanger attempts the transport options with the Transport Failover node of the Configuration Options page. For VMware® ESXi™ hosts, configure the transport order to VA-based HotAdd > VA-based Network.
Savepoints are named using a VMname_date_time_UUID format. Copy the entire directory, which contains a .var file and two .metadata files, for the savepoint in question.
5 Using the Restore from Manifest function documented in Performing a full restore from manifest for VMware VMs, restore the backup to the target VMware® ESXi™ Server at the DR site.
