Live Duo - Need to Sync files on two systems

I just got a Live Duo 6TB that I have set to a RAID1 setup.  I have a Mac Laptop and a PC Desktop.  My question is I want to be able to work on one system and when I save a file for it to sync with my other computer, this way all files will be the same on both systems.  I also will be using the Live Duo for backing up the files and both systems will backup to it as well.  I do not know what would be the best way to do this or what software to use for this.  This is something I have not done before so any suggestions or help would be great.   


We don’t have a software that does that. However, if you save the files manually to the MBLD and the drive drive is mapped on both computer, you will be able to see the files on both.
