A NAS or Network Attached Storage, is a small server that can be used at home or in your office.
We use and recommend Synology NAS servers as they offer good hardware and the operating software gives you enterprise level services for a fraction of the cost. We also use Synology NAS servers in our sister business Protect My Photos, for personal photo storage.
A NAS can store all of your important documents and back them up automatically. it can also act as your own private cloud to share and sync information with your computers.
