NDMP Backup with Netapp

Created: 15 Dec 2012 | 1 comment

I have a backup exec 2012 server that is attached via fiber to a 4GB brocade switch. Off the brocade switch I have a Napapp Filer and a Quantum i80 tape library (both connected at 4GB). I registered the netapp as a NDMP backup device. Under the Storage tab I see the Tape library attached to both the netapp and as a stand alone drvice.

Recently my backups started taking at lot longer than normal and the job rate is about half the speed it use to be (5,000 MB/M instead of 10,000 MB/M when one drive is in use). I also see 90% of the bandwidth of the ethernet nic in use when a NDMP backup is running. I'm pretty sure the traffic is going across the nic insead of direct via fiber. Any ideas on how to fix this issue?

I also notice that under the Storage Tab on the Filer it says that the services on the backup server will need to be restarted. I have restarted them a few times before, but this message keeps coming back.

We did need to replace a tape drive recently in the Library, it seems since then, traffic is now coming from he NIC insead of over fiber.

After replacing the tape drive, did you try this?

1) Delete the library from BE
2) Stop the media server and the library
3) Start the tape library
4) Start the media server
5) Ensure that the library and tape drive is recognised and functioning correctly in the Windows Device Manager. Check that your library is listed in the Windows Device Manager as an Unknown Medium Changer with a Microsoft driver.  If it has a Quantum driver then change the driver to the microsoft driver using the procedure in the documents below
6) In BE, install the library if necessary.
