Import Media Contents to NBU

I've been given a tape from a external customer and being asked to restore from it.  All the info I've been given is that the data consist of tar files from a RMAN backup.  I'm assuming NetBackup was not the method to back it up to tape.  This is due to when I attempt to perform a Phase1 Import I get error:

cannot read media header, may not be NetBackup media or is corrupted(172)
 
I'm assuming the Import is unable to create a HEADER file in the ImageDB because it can't read the media header.  Would this be correct?  So my question, is it possible to Import data from media no matter how or what wrote the data to tape?
 
  • Taper header is a 1024 byte header that is written to the tape at the beginning of the backup.

    This TN describes what this header looks like: http://www.symantec.com/docs/TECH73812

    It is clear from the error that you received that there is no NetBackup header on the tape.
    NetBackup can only read NetBackup and Backup Exec tapes. No other backup software.
