I finally stopped doing direct fs->burner backups too and now do a
mkisofs fs->tmp.iso, and dvd+rw tmp.iso->burner. The gathering of
data from various files (especially the small files like in
/usr/include) was too slow for full speed burner operation. Grabbing
all the data from one huge file was quite a bit faster and was no
problem for burning at 8x DVD speed (~11MBytes/sec). My burner can't
do 16x so I have no idea if my disks and fs would be able to reliably
stream 16x (22MByte/sec) data.
