Prerequisites and considerations for NDMP

Consider the following when protecting NDMP devices:

     The Unitrends appliance must be one of the following:

   UEB running Unitrends software version 8.0 or higher

   A 64-bit, rackmount Recovery-Series model that is 1U or higher, running Unitrends software version 8.0 or higher

     Unitrends supports NDMP version 4.0.

     The Unitrends appliance must be licensed for the NDMP feature. Check for NDMP=X, where X equals the number of NDMP licenses purchased, in the license string under Settings > System, Updates, and Licensing > License.

     Unitrends currently certifies devices from NetApp and EMC (Celerra, VNX, and VNXe). Devices from other vendors can be added as “Generic” NDMP NAS clients. Consider vendor specific limitations when protecting generic clients.

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

     Your NDMP NAS device must be configured with an MD5 password. Clear text passwords are not supported.

     Unitrends dynamically assigns ports between 32768 - 6100 when protecting NDMP devices. If your environment is configured with a firewall, make sure the ports in this range are open.

     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. Schedules with more than nine consecutive incremental backups result in automatically promoted differential backups. See Automatic promotions of NDMP Incremental backups.

     NDMP backups can only be restored to NDMP devices of 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. For example, VNXe devices only support full volume-level restores to the same location.
