I could do it in small chunks but then I would be unable to mount it using -o loop. The target drive is reiserfs, and I've tried ulimit -f unlimited, without it working.

Hi,
What about space on '/mnt/backup.img'?
You should look at this link by
AwesomeMachine.
He has composed a great howto for the dd command on LQ.
I've not had a file error for a bitstream copy for a smaller partition to a larger using;
Code:
dd if=/dev/hda1 of=/dev/hda2 bs=4096 conv=notrunc,noerror
Change the device '/dev/hda#' to your devices. You could use the blocks from 'fdisk -l' to create your 'dd seek' command options to prevent the larger partition problem.
