Store all your digital media in one central location so everyone can securely access it, even remotely. Stream movies and music anywhere in your home. Compatible with both Mac and Windows files.

Features:

• Automatic and continuous backup for all the computers on your network - Now you can easily back up data from all your networked computers with the included continuous backup software. Set it and forget it; every time you save something it's instantly and automatically backed up.
