1. We recently purchased a NetApp FAS3140, it is connected to our network by Ethernet.
2. We have a Windows server 2003 with Syamntec BackupExec 12.5, a LTO4 tape library is directly connected to this backup server via SCSI cable.
3. I enabled NDMP on NetApp and installed NDMP option on Backupexec 12.5
My questions are:
How to configure NDMP on the Backup Exec 12.5 server to back up the data on the NetApp FAS3140 to the LTO4 tape library?
We failed to add the NDMP server to the Backup Exec server. Here is the error message ---  Unable to validate the NDMP server at this time. Do you still want to add it?  If I click Yes and continue, I receive another error, saying  failed to access 10..11.0.150 the directory or file was not found, or could not be accessed.
Please help.

The way I add NDMP Servers is tools -> NDMP Devices->

Add an account with your root username and password.  This should allow you to add a NDMP Server to Backup Exec.

I sloved this from NetApp community, you need to use root account to setup the connection.


NDMP is typically used for NAS data.  It can be used for LUNs, but there are some caveats.  A lun is an object, so NDMP will backup the entire lun and you can only restore the entire lun.  There is no file recovery within the lun with this method.  You need space to restore the entire lun to do any restore.  Also, you backup the entire lun, including blocks marked deleted and white space.  And there won't be incremental backups, since any change in the lun will be a full backup of the lun on the next backup.

 
Sometimes (but not often) backups are done for LUNs over NDMP, but with full knowledge of the caveats above.

 
Typically, we setup a pre and post script in the backup application to mount the "__recent" snapshot created by SnapManager using sdcli (snapdrive command line interface).  SDCLI will let you mount the lun from any any server that has snapdrive installed, and it can be FCP or iSCSI.  Then, backup exec can backup the mounted drives which appear as local disk and you get the benefits of file restore, and no need for an open file agent since there are no open files in the lun clone created for the backup.  At the end of the backup, then unmount script runs.  The sdcli syntax is in the snapdrive guide.  Write the pre-script to mount and post-script to unmount, test them manually, then test them in a backup job.
