Creating a New Media Set

To create a new media set, you must format the backup media (one or more tapes or disk files). The formatting process changes the backup media as follows:

  1. Deletes the old header (if any), effectively deleting the previous contents of the backup media.

    Formatting a tape device deletes all previous contents of the currently mounted tape. Formatting a disk affects only the file that you specify for the backup operation

  2. Writes a new media header on the backup media (tape or disk file) on each of the backup devices.
