    By import, NetBackup read contents of media and recontruct catalogs for images on these media.
    For detail, see Administrator's Guide page 336.

    * NetBackup 6.5 Administrator's Guide for UNIX and Linux
    http://support.veritas.com/docs/290201

    Important: imported media cannot be used for writing data until all the images on it become expired.

    You can import the tapes from the admin GUI.

    there are two phases of tape import

    First phase builds the sceleton metadata.
    Second phase allows you to select which image to actually complete the import process.

    You can do this by two ways -

    1. You can do this from admin GUI.
    2. You can do this from CLI as mentioned below.

    Phase1
    /usr/openv/netbackup/bin/admincmd/bpimport -create_db_info -id D0003 -server megatron -L /tmp/bpimport.phase1 &

    Generate image list:
    /usr/openv/netbackup/bin/admincmd/bpimport -PM -s 01/01/71 00:00:00 -e 09/20/01 23:59:59 -id D0003 | awk '{print $5}' > /tmp/import_list

    Phase2
    /usr/openv/netbackup/bin/admincmd/bpimport -Bidfile /tmp/import_list -L /tmp/bpimport.phase2 &

    Reference -
    http://seer.support.veritas.com/docs/240402.htm

    Note - You can import the media if and only if that is not used again (as expired media is overritable)

     after expire all old images(which have been overwritten) by bpexpdate -m media_id -d 0 -force, then perform import.
    You can get catalogs of data those really recorded on media.

    Make sure you do phase I for 25 tapes, then do phase II.
    Otherwise, you get some error like "premature end of file" or so on, on phase II.

    After this you will be able to see the catalog images in BAR Window, just go there and select the  files u want to restore and start restoring.

    I pray god to get your data as soon  :-)
