How the rman scn based incremental backup works? We have a primary and standby database and we seen some of the data block corruptons in the standby database. The data is loaded on the primary using nologging.. and the Min( non_logged_scn) shows older than 3 months.. My question is the SCN based incrmentl backup will get all the datablocks changed from the primary ..to update the standby using the incremental backup? where do it get the change blocks history of last 3 months.
