Abstract

A service provider network includes a host computer that communicates with a plurality of client devices associated with a user. In order to synchronize the plurality of client devices with respect to content stored within the service provider network, a synchronization service checks to determine if a checkpoint is present within the synchronization service when a request for updated content is received from one of the client devices. If no checkpoint is present in the synchronization service, then content within the user's account may have been updated. If a checkpoint is stored within the synchronization service, then the checkpoint in the synchronization service is compared with a checkpoint in the request. If the checkpoint in the synchronization service is older, content in the user's account has not been updated. If the checkpoint in the request is older, then content in the user's account may have been updated.
