NBU configuration with NDMP Host

Hi All,

I need one help for configuring my NAS device with NBU 7.5.  as I am new to NBU.

I had installed NBU on RHEL-5, Linux machine, and trying to attache my NAS device to take backup via NDMP.

While creating "Storage Unit" in NBU, I am not getting option of  "NDMP Host". Does anyone know why?

I am getting only 2 options, "Basic Disk" and "NearStore". No other option is displaying on GUI. (I am using NBU JAVA console)

I had already added my NAS device under "Credentials" --> "NDMP host". It is getting listed over there.

Even under "Host Properties" --> "Master Server" --> "NDMP" I had added credentials.

Can anyone guide me, how to configure NBU for NAS devcice, to take backup via NDMP?

Thank you.

    You still have not told us what make/model NAS device you need to back up?

    What exactly do you need to back up on the NAS?

    We can see that you have configured a disk storage unit called NAS-1 that will store backups on a mount point called /mnt/vol-1.
    Please tell us more about this mount point. 
    Is this local disk on the master? Or NFS mount on the NAS? 

    The policy shows that you are backing up a client called  linux-1.cluster-12.com. 
    This is your master server, right?
    And the path that you are backing up is     /mnt/vol-1/nbu-test?
    The same path that you are writing your backup to?

    This is not going to work.

    You cannot backup a mount point to itself.

    Firstly - you need backup storage. Either tape or disk.

    If you want to backup the NAS, you cannot use storage on the NAS to write backups to.

    What is confusing is that you seem to have another storage unit that is ALSO called NAS-1 on server linux-1.cluster-12.com with a mount point called /NAS-1/NBU-BACKUP?

    How is this possible?
    Please help me to understand?

    To backup the NAS via NDMP protocol, the policy type needs to be NDMP.
    Select a Storage unit that is NOT on the NAS.
    The client name needs to be NAS-1. 
    The backup selection needs to be the name of a volume/mount point directly on the NAS (not NFS mount on the backup server).

    Please take your time and read through NetBackup for NDMP Administrator's Guide http://www.symantec.com/docs/DOC5164 

    Your configuration will either be  chapter 4: Configuring NDMP backup to NetBackup media servers (remote NDMP)
    or chapter 6: Remote NDMP and disk devices
    (chapter 6 actually tells you that Media Manager (tape) or Disk storage units can be used on the media server. )

    Hope this helps.....

    Are you looking in the correct place?

    I see "Disk / Media Manager / NDMP" under "Storage unit type" whereas "Basic Disk / NearStore" & others if licensed) are under "Disk type".

    Thank you Andy for quick reply.

    I am getting following options,

    under "Storage Unit Type" I am getting only  "Disk",

    and under "Disk Type" I am getting "Basic Disk" and "Near Store". Nothing else.

    What are the possible reasons, as I am not getting "Disk / Media Manager / NDMP" under "Storage Unit Type" ?

    Do I need to configure anything else in NBU for NDMP?

    Any idea?

     

    Regards,

    Ashish.

    Have you a valid NDMP licence installed?

    Presumably Media Manager not available as you don't have tape drives available?

    Yes, Andy. I had checked license, it is Active. 

    Feature:        NDMP (Active)

    I don't have Tape Drives, attached. Does it mandatory to have it?

    Take a look at this...http://www.symantec.com/business/support/index?page=content&id=DOC3671 Chapter 6 covers setting up NDMP backup to disk.

     

    #2. Use the NetBackup Device Configuration Wizard to configure devices for

    remote NDMP (disks, or tape drives and robots, on the media server).
    Note the following:
    ■ Do not use the device configuration procedure in the “Configuring NDMP
    backup to NDMP-attached devices” section of the NetBackup for NDMP
    Guide. Rather, configure the disk, robots, and drives, in the same way as
    ordinary NetBackup devices.
    See the NetBackup Administrator’s Guide, Volume I.
    ■ Tape drives can be shared using the Shared Storage Option (SSO) of
    NetBackup. The drives can be shared as bothNDMPdrives and non-NDMP
    drives.
    See “Using the Shared Storage Option (SSO)” chapter of the NetBackup
    for NDMP Guide.

    #3. Create a disk or Media Manager storage unit for the drive(s). The storage unit

    type must be Disk or Media Manager, not NDMP.
     
    Hope this helps. :)

    Hi C-Ray, 

    Actually I had tried to configure NDMP host via, "Device Configuration Wizard". 

    When I proceed with it, it fails with "illegal duplication" error. 

    Even after this, I had proceed to create Storge Unit, but it failed to create it. 

    When I try  to configure "Devices"  (Under Media and Device Management) I am getting 7 different options. 

    (1) Drives, (2) Robots, (3) Media Server (4) Server Grooup, (5) SAN Clients (6) Topology (7) Disk Pools 
     
    I am confused with these options, as which one is useful to me for NDMP configuration. 
    ------------------------------------------------------------------------------------------------------------------------------------------------------
    (1) Drives - This is for Tape Drives.  ( I don't have Tape Drive, so this is not applicable to me. )
     
    (2) Robots - This is for Automated Cartrised System. ( Not applicable to me. )
     
    (3) Media Serve - My linux machine on which I had installed NBU is already listed here. I am not sure, 
     
                              weather this is correct for my scenario. 
     
    (4) Server Group - Do I require to add my NAS device as Server Group here? 
     
    (5) SAN clients - Not applicable to me. 
     
    (6) Topology - It shows my NBU machine. 
     
    (7) Disk Pools - When I try this, it asks me for appropriate License from vendor. So I think, this is also not applicable for MDMP. 
     
    Is there anything which I am missing here to configure NBU? 
     
    Thank you.

    I need one help for configuring my NAS device with NBU 7.5.  as I am new to NBU.

    I had installed NBU on RHEL-5, Linux machine, and trying to attache my NAS device to take backup via NDMP.

    Not sure what exactly you want to configure - 

    1) Configure your NAS device as backup destination? (Disk storage unit)

    2) Configure NDMP-type storage unit?

    3) Configure NDMP policy to backup your NAS device to 'some other' disk storage?

     

    1) If you want to use your NAS device as backup destination, there is no NDMP involved. You simply configure it as a Basic Disk Storage Unit. Mount the NFS share on your Linux server and use the mount point as Storage Unit path.
    See 'Configuring BasicDisk storage' in chapter 10 of NBU Admin Guide I for details:  http://www.symantec.com/docs/DOC5157

    2) If you want to backup your NAS to a NDMP-type storage unit, you need to have tape connected to your NAS. See these 2 manuals: 
    NDMP Appliance Information: http://www.symantec.com/docs/TECH31885  
    NetBackup for NDMP Administrator's Guide http://www.symantec.com/docs/DOC5164

    3) If you want to backup your NAS device via NDMP protocol to 'some other' disk connected to a master or media server, you need to configure the Basic Disk Storage unit as per Admin Guide I and then select this STU in your NDMP-type policy (provided you have NDMP license for NBU).
