  1. Complete Loss of Catalog


    We suffered a complete loss of our catalog on our master server, water damage
    to the server, but we have some tapes from about 2 weeks ago which we are
    trying to restore, but with a brand new server and new install of NetBackup,
    I cannot figure out how to just dump the information from the tapes to start
    the rebuild process, has anyone had a similar experience to this? How can
    I import the data from the tapes if we have no catalog?

  2. Re: Complete Loss of Catalog

    If they are catalog backups you will need to use the bprecover
    command. Running bprecover with catalog tapes will recreate the image
    catalog. If they are not, then you will simply have to run the import
    process on all of your tapes and rebuild the database that way. Does
    the new server have the same name as the old master server?

    Unfortuneately the tapes do not contain a backup of the catalog, and on an
    import of the tapes, I am having trouble getting anything from the tapes.
    I have imported the tapes, but the client cannot find any backups on the
    server after the import from the tapes.

    Could the retention level cause the tapes to lose their data automatically?
    The tapes we were using were set to a retention level of 1 month, and we
    are barely over that by 1 day since the last successful backup.

    Am I missing a step in the import process? It takes less than 5 minutes
    to import a tape, is it importing all of the data on the tape, or just the
    headers?

    At this point we might have to send the tapes out to a data recovery specialist.

    I know the data is still on the tapes as you can see from the import, but
    how to I get the data from the tapes to restore?

    and schedule Differential-Inc, done on 04/10/2005 18:05:19.
    16:39:04 INF - Recreating copy 1, fragment 1 information for image.

    The import process is made up of 2 steps. Phase 1 which is what you
    described as taking 5 minutes and reads the headers and then Phase 2
    which reads the actual data and builds the catalog so you can browse
    for the restore. Once phase 1 is complete, then go to the Import
    screen and do a search specifying the date range of the backups and it
    should find images to import. Then you can right click on the images
    and begin the phase 2 import. This process will read the entire tape
    so if you are limited on drives I would suggest doing this when you
    have a while between backups.
