master server crash

Hi,

I faced with a situation I'd be grateful if you could help.

I had a master server and a media server attached. we had policies for oracle that connects to the client and started an script to make a backup using rman.

now we totally lost our master server but our backups are safe in the media server. I have to say that we lost the server we have backedup from as well. what can I do to manually add backupfiles to the master server catalog to be able to run the restore script?

we don't have any catalog backup from the master server.

both master and media servers are running on windows server

 

thank you.

    Hi elahe89 

    My recommendation is to call Veritas support or local Netbackup consults to help you out.

    Restoring a master server is complicated and difficult task, not for the faint of heart.

    The fact that you don't have catalog backups, complicated the matter even more.

    One of your FIRST orders of business in data protection is to protect your own master server and MAINLY your NetBackup catalog with backups to recover from. NetBackup provides a way for a Hot Catalog backup and will also send you a Disaster Recovery file for situations exactly like this. But you have to set all this up for your own good!

    I'm trying to think how "I" would even recover from a total loss without a catalog backup.

      Hello 

      DPeaco - I am still having dozen of domains which writes to tapes... Tape manager is receving emails twice a week with information which tapes to take out (weekly, monhtly, daily) and which to put back in (scratch). In the same email I am attaching outcomes from following command:

      bpimagelist -A -media -hoursago 528

      also in the same I am providing this (well there are some pool names etc)

      bpmedialist 

      Of course we do run catalog backups - but I think it is better to have more information than less ;)

      this should provide me some idea what tapes to import in first place.

        This was a badly implemented NetBackup setup. A DR ended up into your data being encrypted!

        Once you have gotten your data back (or not): Best that the backup admin/management look into readying the NetBackup Backup Planning and Performance Tuning Guide. Especially the Best Practices section (it will point you to other admin guides as well). But the very first recommendation for DR in that guide is - "Always use a scheduled catalog backup". Loosing the master shouldn't mean that you loose the catalog - plan better next time on having redundant backup copies of the catalog.

        Better let the management know that recovery isn't going to be easy or 100% or free. Then call Veritas support as suggested above.
