No you didn't do anything wrong. There is no sd-ext to backup simply because you have no sd-ext, and that's okay. Lol
Ext is a filesystem type, and sd-ext would be an ext partition on your sd card. I think it is mostly useful on phones with very low internal memory, such as the Nexus One with less than 200MB available for installing apps. I never used it with my N1 but if i understand it correctly, the sd-ext frees up internal memory by allowing you to mount system partitions to your memory card.
I don't think we really would need one with this phone because we have much more internal memory available from the start.
