A major limitation of XP’s Ntbackup utility is its inability to select a CDRW
drive as a backup destination. To work around this hurdle, open Ntbackup, select the files to back up, then select
C:\documents and settings\username\local settings\applicationdata\microsoft\cd burning\backup.bkf
as the backup destination. When the backup finishes, XP will
prompt you to write the files to the CD-ROM.
