Our setup is like this

OS = Sun Solaris 10, NBU = 6.5.6, Master Server = 01, Media Server = 06

Tape Library = Storage Tek SL8500, Shared Storage Option = Yes,


How to configure in  NDMP so that the all media server’s can see the filer.

Thank You David/Brayan E/Greg/rsavage,

Thanks for you feedback,

I'm back with my results.

We will be backing up NDMP data using remote ndmp to a datadomain ost

I compared and found out I'm getting 300GB backed up in 1 hour at the rate 75000 KB/sec which is much better than local ndmp where we were getting  more 13mb/sec.

Few important points to be considered

When backing up to the DD device make sure you explicitly set  maximum concurrent jobs not more then 150/- (MAX is 180)

While adding the ndmp host to netbackup 7.1 try using command prompt instead of GUI for some reason it was not working with GUI in my case

Best regards

You can do NDMP backups to OST via LAN transport to the media server. All you need to do is setup your ndmp credentials in NBU and on your NAS device. At least this worked for me with a VNX-File NDMP backup.

If you want to transport NDMP backups via SAN to the DATADOMAIN, then you would need the VTL license/HBA on the datadomain.

Hi Team,

I have been given this task to move the NDMP backups from one master server to another.

The current master server backups up NDMP to CDL (Clariion Disk Libraries) typical environment via SAN.

 Now the new master server has no TL/VTL/CDL its just has Datadomain used as netbackup openstorage device.

Now my question is this .

Do I have to procure VTL license from DATADOMAIN in order to do NDMP backups ?

If I do NDMP backups to Datadomain open storage device will it have any performance implications ?

Another point that crossed my mind is this : openstorage backups would be via LAN not via SAN would that reduce the speed of ndmp backups to great levels ?

Anyone who has implement Netbackup NDMP backups on Datadomain please provide me with their valueable inputs.
