The QNAP TS-231P is a network drive for use at home or a small office. Place 2 hard drives in this NAS to automatically backup all your important files. You can even use RAID to store your files twice as securely. Snapshots allows you to easily restore accidentally deleted files, so you can be certain that you won't lose any files. Connect the NAS to 2 network ports to transfer all you data across the network twice as fast. The included software lets you automatically make backups of important emails, notes, and all your contacts. In addition, you can connect the NAS to a cloud storage, so you can also make a copy of your most important files outside of your own network.
