My parents are always paraniod about backing up data, which is important to do, but it gets a bit excessive in their case. They currently have an ancient Apple Time capsule, but they barely use Apple products. I would give my parents a NetGear Wifi Router that comes with a 1TB backup drive. That would allow them to have decent internet speed and range as well as a good backup option for all of their devices. Their old time capsule router/backup drive has such poor range they only have wifi in half the house and it is really time for an upgrade.
