For instance, the application state data may represent an application state of a computer application running at the electronic device when a backup event occurs. An analysis may be performed based on at least one of a user profile or a usage pattern. A set of electronic devices may be identified based on the analysis. Further, the application state data may be transmitted to the set of electronic devices. ## Claims ### Claim 1 A method of application state synchronization, the method comprising: receiving, at a server, application state data from an electronic device, wherein the application state data represents an application state of a computer application running at the electronic device when a backup event occurs;
