You will lose some information going to ISO-9669 format, you may not care. If you want a real backup, loop mount a 4G file with an ext2 and copy everything to that, preserving ownership, etc. Then unmount and burn to a DVD. Linux will be happy to mount an ext2 DVD and all permissions and ACLs will be preserved. Note, I'm just typing this in, engage brain before copying! # cd /tmp # dd if=/dev/zero bs=1M count=4k of=bkup.ext2 # mke2fs [options] bkup.ext2 # mount -o loop bkup.ext2 /mnt/loop # for n in / /boot /home; do cp -ax $n /mnt/loop/; done # umount /mnt/loop # growisofs -Z /dev/dvd=bkup.ext2 I do similar stuff, although if I really care about the data, I often make the loop file smaller so I can add dvdisaster software ECC to the image. hth -- Bill Davidsen <davidsen@xxxxxxx> "We have more to fear from the bungling of the incompetent than from the machinations of the wicked." - from Slashdot -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
