Netbackup catalog recovery

Folks, i need ur inputs on this issue.

NetBackup version 8.3.0.1, RHEL 6  -- no tape library attached. 3 NBU appliances[5240] attached. All our old legacy backup data exist on three NBU appliances. I do have catalog recovery file. Master server is up and running [NETBACKUP IS CORRUPT , SOMEONE MESSEDUP bin files from filesystem]

luckily link is not destroyed
lrwxrwxrwx  1 root root    13 Nov 29  2016 db -> /apps/nbu/dbf

NBU DB is safe and intact under /apps/nbu/dbf . [storage mount]
lrwxrwxrwx  1 root root    13 Nov 29  2016 db -> /apps/nbu/dbf

/dev/mapper/vg--nbu-dbf
                      985G   84G  851G   9% /apps/nbu/dbf

[root@uxbk01 dbf]# pwd
/apps/nbu/dbf
[root@uxbk01 dbf]# ls
kac                class           client          conf.c       db_upload.sh       DBVERSION_7.6.0.1  failure_history  jobs        old-images  symdb
alljobs           class_internal  cltmp           config       DBVERSION_6.5.6.0  DBVERSION_7.7.3.0  IDIRSTRUCT       lost+found  rb.db       tune.h
altnames          class_locks     cltmp_internal  config.mk    DBVERSION_7.1.0.0  discovery          images           mds.db      snapshot    upload.ftp
buffer_status.sh  class_template  cltmp_template  dbtemplates  DBVERSION_7.5.0.0  error              INDEXLEVEL       media       ss          vault

bp.conf file is also safe on storage mount point

Can i do a fresh install on /usr/openv/netbackup [by default install path] ? , stop nbu services , replace new bp.conf with old bp.conf , reuse this [db -> /apps/nbu/dbf] , start nbu services ?

will it NBU start and come back to its pervious state ?

    Unfortunately, the NetBackup catalog is not limited to just /usr/openv/netbackup/db.
    Do you also have the directories /usr/openv/db and /usr/openv/var?
    Please check whether these symbolic links exist.

    If I were you — and since this is legacy data — I would try to reconstruct the master server outside of the appliance and test a copy of the catalog there, just to see if NetBackup can run.
    This would involve recreating all the symbolic links and paths that the appliance’s master server uses (check all paths, not only at top level).
    If that works, then you can attempt it on the appliance itself.

    I’ve never tried this myself, but honestly, I can’t think of another option.

    Do you have a NetBackup catalog backup on tape or on basic disk?

      Do you have a NetBackup catalog backup on tape or on basic disk? - NBU catalog backup was going to NBU appliance via SLP.  [kind remark - this do not matter, NBU master unix is standalone server] - I guess you are thinking of running catalog recovery wizard

    Hello

    If master|primary server is broken I would have setup a new one. Connected the three media servers to it (the appliances), reconfigured storage devices existing out there then ran a import phase I & II against these. Of course it won't be a trivial thing but doable. Within a reasonable time frame this import should be successful.

    Not sure if there was encryption in place etc... But I would have explored this avenue.

    Good luck.

    let us know if you followed your path (copy /paste) , I would like to know if that worked.
    I think quebek​ method (the catalog recovery) is the method I would have followed.
