For backing up/exporting ArcSDE layers (spatially enabled tables) you shouldn't use Oracle's imp/exp tools. You should use the ESRI supplied tools: sdeimport/sdeexport. These tools makes sure that metadata & triggers are exported/imported.

If you have a lot of static (read-only) spatial data you might want to consider using sdeexport/sdeimport as a way to backup your data. You won't have to backup the static data every day (only once, really) so it should be pretty fast. No point and click though, you'll have to write a few shell-scripts.
