Recording into DVD-RW media

[romildo at uber.com.br]

Hello.

I have just bought a DVD recorder and want to make daily backups
of some important files into a DVD-RW media. I am in doubt about
the recommended way of doing this. I am thinking about using the
following commands to be run from a script in /etc/cron.daily

  mkisofs -v -J -R -o /tmp/image.iso -V 'Backup' -A 'Backup' <files to backup>
  umount /dev/dvd || :
  cdrecord -vvv -eject -dev=/dev/dvd blank=fast
  cdrecord -vvv -dao --eject driveropts=burnfree dev=/dev/dvd /tmp/image.iso

Is that a good procedure? I am looking for comments on it.

Regards.
