I think you'd need the same geometry for the partition table to
make sense on the new drive. OTOH, if you only want to use the
backup disk as an actual backup and not play around with it, then
it should work fine.

It just gets left blank. Remember that you probably won't be able
to mount the partitions on this disk. However, you can restore your
original by doing
# dd if=/dev/hdX of=/dev/hda bs=8192k
dd will stop when it runs out of space on hda.
