Hello Experts,

We have a 4 TB Seagate NAS box that we are using to take User Data backup.  We want to backup the data to Tape using Symatec NetBackup which is installed on Windows 2003 server.

1. Is there any specific way to map NAS share on Windows 2003 ??
2. How can we accomplish this backup on our tape drive ??

Regards.

You're going to have an issue here.  Symantec NetBackup requires the symantec agent to be installed on the server which hosts the share - because it wants to use the operating systems' shadow copy facility to be able to open the files which are in use.  Since the Seagate NAS box is a non-windows proprietory OS, you will not be able to install the agent on it.  If you mapped the NAS box as a drive on your Windows 2003 server, you will not be able to select the mapped drive to back up.

I'm not sure which Seagate NAS box you have, but if it supports iSCSI then your only option is to make the disk available as a physical disk inside Windows 2003 using iSCSI initiator.  You can obtain the iSCSI initiator software from Microsoft at http://www.microsoft.com/download/en/details.aspx?id=18986

If it does not support iSCSI, then you're not going to be able to back up the Seagate NAS.  I would recommend obtaining a NAS which does support iSCSI, such as Synology (my preferred) or Drobo.  I am in no way affiliated with either company, please do not see this as a promotional post.

With an iSCSI mapped disk, the operating system treats it like any other physical disk - with all the tools available, including being able to format, set partition type, security, and more importantly - Shadow copy and then backup.   If your Windows 2003 is a 64 bit edition, then you can also make use of GPT (GUID Parittion Table) so that you can make it 1 big partition instead of two 2TB MBR partitions.

Here is a picture of a 3 TB logical disk connected via iSCSI - and as you can see it is a physical disk, just like my OS drive.
