Usage: WBADMIN DELETE CATALOG     [-quiet]  Deletes the backup catalog. Use this command when the backup catalog is  corrupted and recovery is not possible because the disks, DVDs, or remote  shared folders that contain your backups are damaged or lost and cannot be  brought back online.  -quiet          Runs the command with no prompts to the user.
