A more robust strategy is probably required. I highly recommend Oracle Backup & Recovery Handbook by Velprui & Adkoli on Oracle Press as a good reference to learn how to implement sound backup and recovery strategies. A backup strategy is not sound if you do not know how to use the backup to recover from a variety of scenarios.
