I've noticed today when restoring specific datafiles from a full RMAN backup, 
Netbackup seems to be restoring the entire image.  Although I cant seem to find 
where NB is storing the image after the restore (df -k isn't showing a large 
growth), according to the numbers I restoring far more than I need to.  Also 
the restore time is obviously way to long for the number/size of datafiles I 
picked.

My setsize in the RMAN script is 8g so I'm assuming I need to drop that around 
2-4gb.  Filesperset is 50 so maybe that will need to be reduce.  The database 
is around 100g total.

Are there any other options to consider for getting netbackup to restore as 
little as possible thus speeding up the restore times?

Thanks
