dump and restore are filesystem specific, so the real
answer is no, but since you can easily mount an
ext3 as ext2 or convert ext2 to ext3, it might close to
work. if you're lucky, it would work and might treat
the journal as a normal file.
If i were more bored now, i would try it for you, but
you're on your own for now. i think there is a working
dump and restore for xfs.
