NetWorker Block Based Backup failed

There is a new feature introduced in NetWorker 8.x called Block Based Backup.  It is completely rewritten.  So, it is not the same as SnapImage.  It supports Block Based Backup for Windows machine.  For some reason, backup is only successful with Full level backup.  I attempt to start synthetic full backup but it fails.  This is the first client we attempt to use Synthetic full.  We are trying to backup a drive with size of few TB.  Block Based Backup will save the backup time.  We make sure the OS is supported, and BBB is sent to the same media only.  Also, we have weekly full and rest of them are synthetic full.

Eventually, my colleague works with DataDomain and NetWorker support and confirm it is required to enable synthetic backup on DataDomain.  Just login to DataDomain and run the command below.

ddboost option set virtual-synthetics enabled

run the following command to ensure virtual-synthetics is enabled.
