Ol�,
Vc pode usar o dvd+rw-format para formatar o DVD-RW. Exemplo:
dvd+rw-format -blank /dev/cdrom
Depois, vc pode gerar a imagem com mkisofs. Exemplo:
mkisofs -r -J -o backup.iso arquivos
E por �ltimo, vc pode gravar usando o growisofs:
growisofs -dvd-compat -speed=2 -Z /dev/cdrom=backup.iso
Eu fiz um pequeno script ontem para o meu backup usando uma gravadora de
DVD, que de repente pode interessar a outras pessoas e tamb�m ajudar e
melhorar o mesmo. J� vou logo avisando que j� estou usando, mas h� alguns
probleminhas a serem resolvidos! N�o sei o funcionamento no CL8, mas para
usar esse script, vc teria que atualizar o seu kernel...
