A local media player in network communication with a remote storage system stores a portion of content. It then compares the portion of content stored on the local media player with content stored on the remote storage system to determine if the portion of content is duplicated on the remote storage system. If so, the portion of content stored on the local media player is replaced with a pointer to a duplicate portion of content stored on the remote storage system. The portion of content is played back by the local media player at least in part by receiving the duplicate portion of content from the remote storage system if the portion of content has been replaced by a pointer, or by accessing the portion of content stored on the local media player if the portion of content has not been replaced by a pointer.
