An Oracle database in Standby is an exact copy of an operational database on a remote server, used as a backup, and copy for reference, disaster recovery, etc..

A database in the Standby mode is more than a normal backup because it can be put into production disaster in less time than if we had to restore a copy (either from a simple rman or export).Restore a copy from file takes time, and during this period the system is unavailable. With an additional database in standby mode there is nothing (or almost nothing to restore) in case of disaster. Within minutes, allowing the change is continuity of service. It offers the performance advantages of a cluster or safety of the mirror but the ratio of costs versus benefits and leave time seems right to me.
