definatly.
export is just a 'logical backup'.
if the database is used heavily, and there is a large volume of data, export will be costly.
Usuallly exports are done only in off-peak-periods only.
if you are looking to restore the datbase in hourly basis ( in case of a db restore..) you can have rman to do a daily full backup and frequent incremental rman backup. still it will have some performance overhead.
