RMAN is your best friend and the answer to all your voes. You really need to read Backup and Recovery Guide followed by TFM on RMAN and then practice with various scenarios until you can recover your database waken at 3am, blindfolded and with your preferred hand tied behind your back. :) It's not actually too complex once you grasp the concepts, even though 8i RMAN is light years behind what 10g or 11g can do. The docs can be found here:
