Natively you cannot backup to a CDR(W) using the ntbackup utility (start
->programs->accessories->system tools->backup). If you use a program like
DirectCD to format a CD-RW then the system will recognize the CD-RW as a
volume and write to it. However, if the backup image is larger than the
available space on the CD-RW then the backup will fail. This is because
ntbackup cannot span multiple CDs. A third party backup utility must be
used if you wish to span multiple CDRWs.
Another method would be to perform the backup to a hard drive, then use a
CDR and write the backup.bkf file to the CDR(W). Some of these 3rd party
tools allow for large files to span a CDR. To restore you would have to
use the 3rd party tool to rejoin the backup.bkf file before performing a
data restore.
I would recommend though that whatever backup you perform that you do an
Automated System Restore (ASR) backup. This will assist if you have a
crashed box or you need to restore some registry files. Running the ASR
will create a floppy disk that needs to be safeguarded, along with the
backup.bkf file.

Just remember in order to write to a CDRW it must be formatted first
