The Druva backup workflow for Oracle is described below:

Step Description
Step 1 An Oracle Database Administrator triggers the RMAN script with the name of the mount on the Phoenix Backup Store. The RMAN creates an Oracle RMAN backup and stores it on the mount. 

The Phoenix Backup Store creates a recovery point of the Oracle RMAN backup stored on the mount. 
Step 2 The Phoenix Backup Store creates a ZFS recovery point of the Oracle RMAN backup and applies a timestamp to the recovery point. 

The timestamp corresponds to the PUT request made to the Phoenix Backup Store after RMAN completes writing the Oracle RMAN backup to the backup mount. For more information, see Phoenix Backup Store API reference.
Step 3 Phoenix Backup Store uploads the recovery point to the Druva Cloud. This recovery point serves as a recovery point.
After the recovery point is uploaded to the cloud, it is deleted from the Phoenix Backup Store.

Every time the Database Administrator runs the RMAN script, the RMAN creates an Oracle RMAN backup on the mount. The Phoenix Backup Store creates a new recovery point of every new Oracle RMAN backup that RMAN creates and stores on the mount and uploads the recovery point to the cloud creating a new recovery point. 

RMAN can store backup data until sufficient storage is available on the Phoenix Backup Store.  If sufficient storage is not available, RMAN cannot store backups and the backup jobs fail. Ensure that you periodically remove Oracle RMAN backups from the the Phoenix Backup Store or increase storage capacity on it.
