Container-Based Application Data Protection Method and System

Abstract

A computer-implemented method of data protection for containerized applications includes initiating a backup process for a containerized application comprising an application template, application information, and application data. An application template associated with the application is saved to a first repository. Application information is identified and saved to a second repository. A persistent volume containing the application data is identified and at least some of the application data from the persistent volume is saved to a third repository. The application is then restored based on the saved template, application information and application data.
