Abstract

Technology for a method for backing up and restoring application state across multiple devices is disclosed herein. The method includes running an instance of a computer application at a first electronic device, determining a backup event that occurs in the first electronic device, wherein the backup event suggests a backup of application state data and the application state data represent an application state of the computer application at the backup event, and transmitting the application state data of the computer application to a remote storage service, in response to the backup event. A second electronic device can retrieve the application state data from the remote storage service and restore the application state.
