Embodiments of the present invention provide a system for calculating and executing data backup policies for a multi-tenant cluster storage. The system is configured for accessing one or more audit logs associated with one or more applications, where the one or more applications comprise one or more folders, accessing a footfall database to identify footfall data associated with the one or more applications, determining criticality of the one or more folders associated with the one or more applications based on the footfall data, determining a dynamic backup policy schedule for the one or more applications, storing the dynamic backup policy schedule in a backup policy database, based on the dynamic backup policy schedule, determining that at least one application of the one or more applications needs backup at a current time, and executing a backup policy and take a backup of the at least one application.
