US Patent 11003632 System and method for content synchronization

One embodiment of a system comprises a client computer and a remote content management system. The client computer comprises a synchronization manager that maintains a remote virtual model that models a synchronization state of a remote peer data resource at the content management system and a local virtual model that models a synchronization state of a local peer data resource in the local file system. The synchronization manager determines that the remote peer data resource and local peer data resource are out of sync based on a comparison of the remote virtual model and the local virtual model and synchronizes changes from the local cache to the content management system to update the remote peer data resource or changes from the content management system to update the local peer data resource.
