How to create a copy of DVD that is larger than maximum size of file on filesystem?

Question

How to create copy of DVD, which ISO image size is larger than maximum size of file on filesystem? There is only one DVD drive.

What UNIX/Linux filesystem are you using that has such a small maximum file size? — pdo, Feb 16 '11 at 19:14
VFAT (FAT32) in quite old kernel has limit of 4GB file size. — Jakub Narębski, Feb 16 '11 at 20:51

As long as you don't mind that the intermediate storage won't be usable as such:

split -b 1024m /dev/dvd iso-pieces.
# Pop out original, pop in blank
cat iso-pieces.* | growisofs -Z /dev/dvd=/dev/stdin

Thanks. I will probably use dd or cdread instead of split-ting on device, though. – Jakub Narębski Feb 18 '11 at 12:26
@Jakub: dd is useless here, it won't do anything for you that cat wouldn't do. But see Calculate md5sum of a CD/DVD about reading a CD's filesystem image exactly. – Gilles 'SO- stop being evil' Feb 18 '11 at 18:22
I meant using e.g. dd if=/dev/dvd of=iso-piece.2 bs=1024m count=1 skip=1024m etc. instead of split. – Jakub Narębski Feb 22 '11 at 11:08
