You can import the tapes but you need NDMP host to restore the data.

From Network Data Management Protocol (NDMP) System Administrator's Guide for UNIX and Windows ( http://support.veritas.com/docs/279269 ) -


Performing a Restore from the Server
User-directed restores of files are not allowed, since there is no NetBackup client software installed on an NDMP host.
The administrator can use the Backup, Archive, and Restore interface on a NetBackup server (master or media server) to restore files to the NDMP host from which they were backed up, or to a different NDMP host. For help with the basic restore procedure, see the NetBackup online help in the Administration Console, or the NetBackup Backup, Archive, and Restore Getting Started Guide.
Note the following:
In the Specify NetBackup Machines and Policy Type dialog, specify the following:

For the server, select the NetBackup master server. If your configuration has multiple master servers, specify the master server that has the policy for the NDMP host that you are restoring. If the server name is not in the pull-down, use Edit Server List to add it.

For the source and destination clients, select the appropriate NDMP (NAS) hosts.
Note The destination host must be an NDMP host compatible with the data format of the source (the source and destination must be of the same NAS vendor type).
Caution An NDMP restore always overwrites existing files.
If the desired hosts are not available in the pull-down, use Edit Client List to add the client.
◆ In the policy type field, select NDMP.


NDMP Operating Notes and Restrictions

Before troubleshooting a suspected problem, review the following operating notes.
To obtain troubleshooting information that may apply to particular NDMP hosts, refer to �NetBackup for NDMP Information on the Web� on page x.

A tape created on an NDMP storage unit is in backup format and cannot be restored from a non-NDMP storage unit. If you duplicate an NDMP backup image the new copy is still in backup format and cannot be used for restores on a non-NDMP storage unit.

In the Backup Selections list for an NDMP policy, you can include only directory paths. Wildcards and individual file names are not allowed.

You cannot back up files where the path length is greater than 1024 characters.

The NDMP protocol uses port 10000 for communication.

On UNIX systems, the NetBackup avrd process utilizes ICMP (Internet Control Message Protocol) to ping NDMP hosts to verify network connectivity. This protocol is required for the NetBackup for NDMP product.

If backup or restore jobs are running slowly, verify that the network interface cards (NIC) are set to full duplex. Half duplex often causes poor performance. For assistance viewing and resetting duplex mode for a particular NAS host, consult the documentation provided by the manufacturer. You may be able to use the ifconfig (or ipconfig) command, as explained in the NetBackup Troubleshooting Guide.

This was a good post, Rakesh. You should get some points for it.
