NDMP is kind of an open standard which is supported by most of the backup software. Nothing has changed in VNXe3200 related to NDMP (compared to VNXe3150), so I say it should work from any backup software.
I cannot find any backup software that supports NDMP backup from VNXe3200. Does anyone know about this?  Symantec used to support VNXe3150 but it is not any more. .
