Use resize2fs to resize the ext2/3 filesystem (use reiserresize (I think) for reiserfs) to shrink it (i.e. make sure that nothing beyond 760 Mb (for example) is used. Then copying the first 760 Mb should work. Once in the destination partition use resize2fs to expnd it to fit the partition and you're done.

I think, Linux filesystem's 'unlike DOS, Win, and such' don't defragment because they don't need to.

They don't need defragmentation. All that resize2fs does is guarantee that no part of the filesystem extends beyond the given boundary and changing the filesystem's internal size field to prevent ext2/3 from allocating a block beyond that boundary subsequently.
