A system and methods for enhancing content collaboration by conflict detection and resolution. A hybrid cloud cache receives a request from a client to upload an object to the cloud. The hybrid cloud cache may perform an internal lookup to find the latest version of the object known to it. This lookup may return a local identifier or a cloud identifier. The cache may compare a client-provided identifier to the local identifier or to the cloud identifier that is mapped to the local identifier to determine if the client-provided identifier refers to the latest uploaded version of the object. The system may determine that a conflict exists if the client-provided identifier does not match either identifier. The system may generate an alternate name for the object and upload the renamed object to the cloud from the hybrid cloud cache.
