    When a tape is full, NetBackup will not write anymore backups to it.
    NetBackup will look for a new tape to write backups.

    The Full tape will keep this status until ALL images (backups) on this tape have expired. The expiration date is determined by the Retention Period that is selected in the Policy Schedules.
    The tape will then be 'unassigned' and become available (go into Scratch).
    Only at this point can the tape be overwritten from the start.

    Hey

    Your data which is not not compressing 1:2.5 and that's all.

    So whenever I am sizing tape drives I do never take into account tape/library capacity based on assumed compression - always native. By doing so I am on safe side ;)

      f the tape is full, does netbackup stop recording data or does it write new data and delete old data?
