backuptodvd

======  Tape-Like Backup  ======
tar cvf - -C /files/to/backup | growisofs -Z /dev/dvd=/proc/self/fd/0
Restore:
tar xvf /dev/dvd

======  Backup with UDF-Filesystem on DVD  ======
As packetwriting is not very good today under Linux, we can do it this way:

Create image file:
<code>
 # dd if=/dev/zero of=./dvd_backup.img bs=32768 count=143444</code>
Create UDF filesystem inside the image:
<code>
 # mkudffs --media-type=dvd dvd_backup.img</code>
Create mountpoint and mount the image:
<code>
 # mkdir mnt
 # mount dvd_backup.img mnt -o loop</code>
Copy files to the image and unmount it:
<code>
 # cp -a /files/to/backup mnt
 # umount mnt</code>
Burn the image to DVD:
<code>
 # growisofs -dvd-compat -Z /dev/dvd=dvd_backup.img</code>
