Working with backup sets : VMware VADP backup sets (Windows or Linux) : Before you begin
 
Before you begin
Before creating a VMware VADP backup set, you must ensure that the following requirements are met as applicable:
For application consistent backups, ensure that VMware Tools is installed on the guest operating system of the virtual machine.
If an ESXi host is added with its DNS name to the vCenter Server, the DS-Client machine must be able to execute a name resolution for that ESXi host to back up or restore the virtual machines.
If you plan to enable the Local DS-VDR option, you must have configured the Local DS-VDR Tool for the DS-Client. For more information, see “Configuring the Local DS-VDR Tool”.
