1. A method, comprising:
generating an aggregated access history for applications, wherein the aggregated access history includes a local access history from each of the applications, wherein the aggregated access history tracks IO (Input/Output) operations between the applications and storage devices;
performing a time series analysis on the aggregated access history to determine which of the storage devices were accessed by each of the applications;
identifying consistency groups for each of the applications based on the time series analysis of the aggregated access history, wherein each of the consistency groups includes some of the storage devices accessed by a corresponding application; and
performing a data protection operation on each of the applications, wherein the data protection operation is applied to all of the storage devices in the corresponding consistency group of the application, the data protection operation including a backup operation.
