The backups can be in real-time or on a routine basis, with QNAP’s ‘NetBak Replicator’ available for Windows computers and Apple’s dedicated Time Machine backup program for Apple computers. Additionally, you can use the front USB port to back up an external hard drive’s content at a touch of a button.
As a contingency for losing your important documents or backups from being lost forever, you can enable a number of different features this NAS has. One of these is RAID configurations, with RAID 1 available to provide you extra copies of your files. Using ‘backup station’ you can also create remote site backups of your data, locally, to another NAS or to the cloud

Utilising myQNAPcloud service, you can effortlessly setup remote access to your QNAP NAS drive. This gives you access to your files through the myQNAPcloud portal, mobile apps or through the Qsync PC utility. Mobile apps include Qphoto, Qmusic and Qvideo for multimedia access, Qmanager for NAS status checks and Qfile for managing/downloading/uploading files.
Through the app center, via QTS, you can install various apps onto your NAS drive, increasing the amount of features it has to fit your needs. ‘Surveillance station’ is an app you can install which allows you to record from up to two IP cameras**, since two free camera licences are provided. ‘HD station’ transforms the NAS into a multimedia device, with support for multimedia player apps, browsers and other streaming platforms. ‘Virtualization station’ and ‘container station’ allow you to run multiple operating systems, and just by plugging in a monitor/TV, keyboard and mouse, you can use your NAS as a PC.

Can I play my media files stored on the NAS to other devices?
Playing content from the NAS drive doesn’t need to be done through a router, just plug it direct to a monitor or HDTV and enjoy your multimedia content. The built-in DLNA server lets you stream multimedia files with DLNA/UPnP devices that are on the same network, for example a PlayStation 3 or Xbox One, without pre-configuration. Through transcoding (converting file formats to universally readable ones), this NAS can enable devices to play content even if they don’t natively support a certain file format.
