1. A method of protecting data depending upon importance, the method comprising: identifying a level of importance for each data item of a plurality of data items of a database stored in a primary data storage repository; tracking changes to the plurality of data items to identify changed data items of the plurality of data items; aggregating the changed data items using respective ones of a plurality of data protection methods corresponding to the level of importance for each changed data item of the changed data items; and logging each of the aggregated changed data items to one of a first log in the primary data storage repository or a second log in a secondary storage repository in accordance with the data protection method used for each of the aggregated changed data items, wherein aggregating the changed data items comprises: aggregating first data items of the changed data items using a first data protection method of the plurality of data protection methods that aggregates changes more often than a third and fourth method of the plurality of data protection methods aggregate third and fourth data items of the changed data items, respectively, the first data items having a higher level of importance than the third and fourth data items, aggregating second data items of the changed data items using a second data protection method that aggregates changes more often than the third and fourth methods aggregate changes to the third and fourth data items, respectively, the second data items having a higher level of importance than the third and fourth data items, and aggregating the third data items using the third method that aggregates changes more often than the fourth method aggregates changes to the fourth data items, the third data items having a higher level of importance than the fourth data items, wherein the first method comprises performing synchronous replication on the first data items, and wherein the second method comprises performing Continuous Data Protection (CDP) on the second data items.
