I have a BUFFALO DriveStation 3TB USB 3.0 External Desktop Hard Drive HD-LC3.0U3. I have it connected to my netgear model 6900 router, I have been able to back up all my documents, pictures, music, and etc. to my external hard drive, but I cannot figure out how to set up the other features on my Hard Drive? mainly the automatic backups feature. Can any one help with this?
