Symptoms
The PowerProtect Data Manager is used to protect the vSphere environment with the Transparent Snapshot Data Mover (TSDM) solution. The virtual machine (VM) backups were working successfully and then started failing with an ABV0025 exit status.
Figure 1: ABV0025 Error details.
ABV0025: VM Direct engine is unable to configure Protection for the virtual machine 'MY_VM' on vCenter 'MY_VCENTER'.
The VM Direct engine cannot complete protection of this virtual machine because the protection configuration was unsuccessful.

Cause
PowerProtect Data Manager initially uses one of the Management networks to connect to the Data Domain and determine the target backup path for the backup. The PowerProtect Data Manager appliance is not able to communicate over one of the "Management" networks configured on the Data Domain Storage network settings. The Management option was selected for a Data Domain interface that was not routable to the PowerProtect Data Manager and was intended for data purposes.
Resolution
The PowerProtect Data Manager requires management communication capabilities to the Data Domain. The Data Domain Storage network settings can be updated with only Management networks routable to the PowerProtect Data Manager Appliance. The configuration may be altered under "Infrastructure > Storage > Data Domain > More Actions > Change Network Settings."
Figure 2: Data Domain storage network settings.
The remaining interfaces should be configured with the appropriate datatype. The Virtual network traffic types are described in the PowerProtect Data Manager Administrator Guide. For your convenience, the most recent versions of the product documentation are available for download on the Dell support website in PDF format. https://www.dell.com/support/home/product-support/product/enterprise-copy-data-management/docsPowerProtect Data Manager may also be configured with a secondary network with access to the Data Domain IP that is being used for Management traffic. The secondary network may be configured under "Infrastructure > Networks."
