Prerequisites and considerations for NDMP

Consider the following when protecting NDMP devices:

     Protecting NAS devices using NDMP is supported on Recovery-Series and UEB appliances running software version 8.0 or higher.

     The Unitrends appliance must be licensed for the NDMP feature. Check for NDMP=1 in the license string under Settings > System, Updates, and Licensing > License.

     Unitrends currently certifies devices from NetApp and EMC. Devices from other vendors can be added as “Generic” NDMP NAS clients, but behavior for generic devices is unpredictable and unsupported.

     It is important to be familiar with your vendor’s documentation and limitations because they can affect Unitrends protection of your NDMP device.

     Unitrends appliances use port 10000 when protecting NDMP. Port 10000 is open for the following security levels: No Security, Low Security, and Medium Security. You cannot protect NDMP devices if you set your Unitrends appliance to High Security. For more information, see About security levels.

     Full, differential, and incremental backups are supported for NDMP clients. Selective backups are not supported.

     Enterprise backup scheduling is not supported for NDMP clients. When you enter the Enterprise backup subsystem, all NDMP clients are disabled in the Navigation pane.

     Because NDMP NAS devices normally have a limited number of NDMP connections, backup and restore jobs for NDMP clients are queued and run as NDMP connections become available.

     A recurring full backup must be in the schedule.

     NDMP only supports nine consecutive incremental backups between successful fulls and differentials. For schedules with more than nine incremental backups between each full, the tenth incremental is automatically promoted to a differential.

     NDMP backups can only be restored to NDMP devices with the same vendor. For additional compatibility limitations see your vendor’s documentation.

     When performing point-in-time restores for NDMP volumes, you cannot specify files to include or exclude. The volume is restored exactly as it was at the selected recovery point.

     Selective restores are supported for some NDMP devices from the certified vendors. See the vendor documentation for compatibility limitations.
