The frequency of each backup type depends on the type of data that you are protecting. The frequency of full and incremental backup depends on the volume of data, criticality of the data being mobilized, and recovery point objectives. It is a common practice to perform full backup after the initial installation, and before and after major upgrades and scheduled maintenance. Incremental backup is based on the recovery point objective (RPO) service-level agreement (SLA), that is, the maximum amount of lost data you can tolerate in the event of a disaster. Alternatively, incremental backup can be based on the length of time your organization can function without access to the data in your database.
