The latest versions of QNAP’s firmware have introduced new backup features. The TS-419P II can act as an Rsync server and offers QNAP’s exclusive Real-Time Remote Replication technology. You can program any number of tasks for folder copying or synchronization to be launched at a user’s request or by a schedule. RTRR can work with remote FTP servers or local external disks. You can specify a separate list of backup tasks for the latter, by the way. Filters by size, date or file type can be applied.
Notwithstanding the integrated support of the AFP protocol, for Mac OS X’s Time Machine to work you first need to set the NAS up by choosing a disk volume and password. You can limit the maximum backup size and remove outdated copies.
Following the latest cloud trends of the IT market, the TS-419P II supports Amazon S3 and ElephantDrive which provide a simple and easy way of securing your important data. The cost of the service may turn out to be too high for large amounts of data, though. On the other hand, cloud services are a perfect solution for storing data remotely. Backup tasks are managed in the NAS's web interface for Amazon S3 and through the dedicated interface for ElephantDrive.
The cloud topic goes further in the MyCloudNAS feature. It helps users implement web-based access to the NAS's services. It’s easy to publish services with MyCloudNAS: just choose a third-level domain on the servers provided by QNAP and specify your services. Your router must support UPnP and you have to provide a public IP address. That’s a handy alternative to learning the details of dynamic DNS and router’s port translation.
Like most modern NASes, the TS-419P II can run a Web server. It supports php and MySQL for complex websites. You can also use HTTPS/SSL and virtual hosts, change port numbers and edit the php.ini file. A few programs are available as QPKG packages for this usage, including Joomla and WordPress.
Users can access documents remotely via their web browser using Web File Manager. It supports access rights defined by the admin and can do everything a typical file manager can do. Security is ensured through HTTPS.
The TS-419P II offers a few multimedia features for home users. Multimedia Station allows publishing a photo album, music or video online to share them with your friends. This system has a dedicated user database and cannot compromise the rest of the NAS. Multimedia files can be grouped into folders or albums and assigned different access rights. Comments can be added to photos. Audio files can only be listened to. Videos are played in a web-browser using Adobe Flash technology or after being transcoded into FLV (the transcoding is rather slow on the NAS's processor).
If you have iTunes on your PC, the NAS’s iTunes server can provide a network collection of music and video for it. The only disadvantage is that you can only access it from a mobile device when your iTunes PC is turned on.
The TS-419P II has a DLNA server as well. It’s implemented with the TwonkyMedia software, like in other QNAP products. This server can index files in any folders, supports all modern high-definition video formats and is compatible with a large number of client devices. It has a dedicated web interface for setting up. You can additionally install a SqueezeBox server as a QPKG package or update the default DLNA server to the latest version.
Downloading files without using a PC is one of the most frequent applications for a NAS, but QNAP hasn't revised the interface and functionality of this feature for years. The number of simultaneous download tasks for the BitTorrent protocol is limited to 10 in the TS-419P II. The setup options are standard: port numbers, speed and connection limits, and seeding limit in percent. The NAS can also download files via HTTP and FTP and supports rapidshare.com accounts. The download station can work by a schedule (two periods per day with a precision up to 5 minutes). Downloads can only be managed by the admin via the web interface or the QGet utility.
If you are not satisfied with the functionality of the integrated download software, you can install the popular Transmission tool which offers more setup flexibility. It can be managed via a web interface or specialized client software.
QNAP is known for its specialized video surveillance products, so the company’s NASes can work with IP cameras, too. The number of cameras supported simultaneously depends on the NAS’s performance. The TS-419P II can record video in four streams, using MJPEG, MPEG4 or H.264 codecs. PTZ, audio recording, camera's motion sensor are all supported, too. The compatibility list includes all the prominent brands, including Axis and Panasonic. The video surveillance system can only be accessed by the administrator. You need Internet Explorer with extra plugins for full-featured work (live streaming and watching archived videos).
Four new features have been added to the NAS with the latest firmware updates. The first of them is the Syslog server which can be used for storing and processing logs of various network devices, e.g. routers or the NAS itself. The second server is RADIUS. It can be used for access control (for example, to control wireless clients connected to an access point).
QNAP has introduced an antivirus feature based on the ClamAV software. It can be scheduled to perform regular scanning of folders specified by the user. If it identifies a virus, it can report to the user, move the file to quarantine or remove it altogether. It can scan archives and apply filters for file types. Its virus database can be updated regularly via the Internet or by the user.
The integrated TFTP server may come in handy for some applications. You can specify the root folder in its settings and limit the IP address range of clients, if necessary.
