Restore_Options=file-name

    Generates an options file designed to be used with the Options
    qualifier of the RMU Restore command. If you specify a full
    backup operation, all the storage areas will be represented in
    the options file. If you specify a by-area backup operation, only
    those areas included in the backup will be represented in the
    options file.

    The Restore_Options file is created at the end of the backup
    operation.

    By default, a Restore_Options file is not created. If you
    specify the Restore_Options qualifier and a file, but not a file
    extension, RMU Backup uses an extension of .opt by default.
