Claim 16:
17. A system for managing metadata for replicating data using data criticality, comprising:
a hypervisor having a virtualization I/O filtering (VAIO) driver to write data to a primary data store;
a data collection module collecting information about data to be replicated from a data source of a plurality of data sources comprising server computers comprising source endpoints in a data storage network performing a replication application;
an analytics engine categorizing, in real time, the data source as critical or non-critical as the data is received by analyzing the data collected in the collecting step using a time-series model using data attributes of a server of the data source, and including at least one of: server type, data type, tenant and project characteristics, storage location, device capabilities, and virtual machine priority, and continuously updating the categorization of the data source at defined time periods based on the time-series model and to meet requirements of a service level agreement (SLA), and further tagging the data source with a current and respective critical or non-critical tag based on the categorizing and updating steps;
a replication policy creator dynamically defining a replication policy for the data to be replicated based on an updated categorization of the data source and the corresponding tag; and
a backup server storing data tagged as critical using synchronous replication and data tagged as non-critical using asynchronous replication in a secondary storage site separate from a primary storage site originally storing the data, and transmitting the tagged data to the primary data store through the VAIO driver, and wherein VAIO driver comprises filters configured to read data attributes for transmission and processing as the information about the data by the analytics engine.
