As good as Plex Sync may be at keeping media libraries in harmony, it's not very helpful to mobile Plex users who can't always store or stream large files on their devices. After today, they won't have to worry. The company has just launched a beta version of Cloud Sync, which saves streaming-friendly content in third-party cloud storage services like Box, Dropbox and Google Drive. Any metadata carries over, and users can even spread their media across multiple providers; they can reserve one host for movies and another for photos, for instance. Cloud Sync is only available to PlexPass subscribers, but the required (and much faster) new Media Server release is available to everyone.
