NDMP Restoration success but no files restored

Hi experts,

 

I have got an issue with NDMP restoration. ( Netbtackup  6.0 , Sun Storage NAS 5320 )

I have few tapes which were having 2009 year data, when I am trying to restore the data and the tape was properly mounted and positioned, read, everything seems to fine.

The restoration says successful, But I could not find any files in the destination folder. No mater How many times I try to restore the result is same. i have checked for the

I have done reboots,  tape inventory , and power cycle also, But no luck.

Is there any thing that could solve my issue.

Awaiting for your valuble replies

    If you are trying to restore to NFS mount it is no longer NDMP. Or is backup source NDMP that you are trying to restore to NFS mount? I don't think that is supported. We may be able to provide better assistance if you share all relevant details. Screenshots of all restore steps, starting with machine names and policy type, up to where destination path is specified, will help to get a better understanding.

    As Marianne said, please tell us more.  What is the backup type? NDMP or Standard? You can only restore NDMP to NDMP i.e. directly to the filer, not via a mount.

    Hi

    Please find the below source and dest path of the ndmp restore.

     

    source :  /Vol1/data/long/00kl29ref

    Dest : /Vol300/RESTORATION_NAS/long-proj1/20-12-2008_15-01-2009/Vol1/data/long/kl0029ref

    Also please find the attached snapshot.

    I remember similar issues many years ago which probably had something to do with either NBU or NDMP version.

    Problem is that NBU 6.0 is so old (released in 2005 and EOSL in 2012) that I cannot find any documentation.

    Is the destination folder totally empty or folders underneath it?
    There is a possibilty that source folder (or portion thereof) may be added to the end of the path.
    This could end up in destination path being too long.

    All I can suggest is to look at NBU logs:
    bptm and bpbrm on NDMP media server and ndmp unified log on the master.

    Disable DAR for NDMP disabled

    (Direct Access Recovery)

     

    Host Properties --> Master Server --> Properties --> General Server

    then disable "Use direct access recovery for NDMP restores"

     

    Run restore again after diasbling the DAR. Restore should work fine.
