How to Verify netbackup version from catalog backup on tape

Hello Team,

I am in the process to recover catalog backup on tape and the NBU environment doesn't exist. I tried to read the contents on tape and was able to extract the TAR file and also imported the DR file for catalog recovery.

I can see netbackup version in below path

1)  /usr/openv/netbackup/db

the DB version file for 6.5, 7.1.0.4 and 7.5.0.0

2)   /usr/openv/var/global

directories for 6.5, 7.1.0.0, 7.1.0.4

Looking at /usr/openv/netbackup/db

I thought that the latest version would be 7.5, and tried the recovery, the images files were restored but the database restore failed, I am attaching the log file.

I tried to extract the staging folder from tape by reading the TAR file and copied the staging folder on /usr/openv/db/staging and performed the manual recovery, it gets completed but then nbemm doesn't come up, although nbdb_admin -validate completes with no errors.

I am not sure how to check the exact Netbackup version from catalog backup stored on tape, I checked the .f files and _FULL files but didn't find the nbu version.

Appreciating your help to find a way to check the netbackup version from catalog backup.

Regards,

    Hi Priyeranjan 

    Okay - if you look at the reload.sql file, in the create table section, you will notice that the NetBackupVersion, is the 14th field (also, the machine NBUtype is field 8). 

    From the screenshot, the second line shows the master server (NBU type 3) "blackops.playstation.sony.com" with the version showing as 750600 or 7.5.0.6

    Cheers

    I saw your question and I find it intriguing, so I do a small search.

     First of all the DB version file under netbackup/db does not reveal the netbackup version. It may be 7.5 but ict can be higher.

    My version is 10.0.0.1 (and windows 2016) and what I found nay not work with your version.

    The only file in the catalog that in my installation reveal the netbackup version is the config_parameters file under netbackup\temp folder.
    Just search your catalog backup and if present, restore this file.

    KEEP_JOBS_SUCCESSFUL_HOURS = 240
    KEEP_JOBS_HOURS = 240
    EXCHANGE_ENABLE_SIS = NO
    VERSIONINFO = "Windows2016" "10" "win_x64" "NetBackup" "10.0" 1000000
    RESUME_ORIG_DUP_ON_OPT_DUP_FAIL = YES
    USE_VXSS = PROHIBITED
    EMMSERVER = ptclnbu01.performance.gr
    EMMPORT = 1556
    VXDBMS_NB_DATA = D:\Program Files\Veritas\NetBackupDB\data

    To be able to start the database the server would need to be configured to use the same name as the master when it was backed up.

    If you managed to restore the staging folder check you the server is configured with the same name as shown in the vxdbms.conf file ( but without the leading NB_)

    If you installed nbu with a different name you will not be able to do the recovery.

      I was able to verify the master server name from dr file imported from tape and the bp.conf

      The master is set with same name as you can see in the logs.

      I didn’t see the temp folder, not sure what else will help

      Hi Priyeranjan 

      If you are able to validate the database, then you may also be able to unload it. Try this command (specifying a destination directory - in this case /tmp/db - it needs to exist first):

      /usr/openv/db/bin/nbdb_unload -staging /tmp/db -t EMM_Machine

      The EMM_Machine table will contain the master server (most likely the second entry of the master name, the first being the "server" entry) and will include the version number - the reload.sql file will tell you which field precisely, but it might be the 14th. The string shown will need to be "converted" as there will be no dots shown - for instance on my NetBackup 10.0.0.1 lab, the version is shown as 1000100.

      Cheers

        To clarify - the staging option above will read the database from the staging directory (/usr/openv/db/staging) rather than the "normal" location. And the database doesn't need to be up to run the command.

    Hi David,

    I was able to run the below command and got the output but am unable to validate the version. Could you please help me to find out the version in the attached files?

    /usr/openv/db/bin/nbdb_unload -staging /tmp/db -t EMM_Machine

    Regards,

    Priyeranjan
