I have a media collection which I access through a Raspberry Pi media server (running raspbmc). My family had become accustomed to having this library at their disposal when I was living at home, but now that I don't live at home anymore (thank FSM), that media is lost to them. Here is my solution: 1. Media added to my personal computer 2. Raspberry Pi #1 checks for new files (still working on automating this) and takes any new files and saves it to the external drive connected to Pi #1 and deletes the original. 3. Pi #1 then syncs with Pi #2 (or any other Pis) which is located at my family's house with it's own external drive. All I need to do is add media to my personal computer, and now my family has access to the same media without doing anything on their end. I also have a separate partition on both drives that act as a family backup that all computers make nightly backups to, which also get synced.
