Integrated virtualization and container solutions
Virtualization Station allows you to host virtual machines (VM) on the TS-873U and access them via a web browser or Virtual Network Computing (VNC), while Container Station integrates LXC and Docker® lightweight virtualization technologies for operating multiple isolated Linux® systems on TS-873U as well as downloading apps from the built-in Docker Hub Registry®. Container Station also supports the QIoT Containers platform that helps quickly structure your IoT environment and deployment on your private IoT cloud. No longer constrained by physical network performance, the Network & Virtual Switch greatly increases data transfer between VMs, containers and NAS through the internal interface.
Optimized collaboration with cross-platform file sharing and sync
The TS-873U centrally stores data, logs and various files, and supports SMB/CIFS, AFP, and NFS protocols for file sharing across Windows®, Mac®, Linux®/UNIX® networks. Coupled with Qsync - a utility that turns a QNAP NAS into a safe, high-capacity data center for file synchronization - any file uploaded to the TS-873U will be made available for all linked devices, such as computers, laptops or mobile devices. You can sync shared folders and team folders for group file sharing, greatly enhancing the flexibility of team projects and collaboration.
Well-rounded backup & disaster recovery solutions
The TS-873U offers flexible backup solutions for Windows® and Mac® users, Volume/LUN snapshots (block-based LUN* and file-based LUN), Folder snapshot, Snapshot Replica and Clone. It also supports Hybrid Backup Sync that consolidates backup, restoration and synchronization functions (using RTRR, rsync, FTP, CIFS/SMB) for easily transferring data to local, remote and cloud storage spaces as a comprehensive data storage and disaster recovery plan.
* Up to 256 snapshots per volume or LUN, and a maximum 1,024 snapshots per NAS. It is recommended to use block-based LUN snapshots.
Comprehensive security to protect your data
In open network environments, business data may be exposed in a potential hack. The TS-873U provides numerous security options, such as antivirus, encrypted access, IP blocking, 2-step verification, and more. IT administrators can also control the access rights of each user to different folders, preventing unauthorized access to important files. The TS-873U supports AES 256-bit encryption, preventing sensitive business data from unauthorized access and breach even if the hard drives or the entire system were stolen. Windows AD server, LDAP server, and built-in LDAP service are also supported.

Secure access with VPN & Proxy Server
The new QVPN app combines VPN Server and VPN Client functionality. Through QVPN, the TS-873U can be used as a VPN server with L2TP/ IPsec, OpenVPN, and PPTP support, allowing you to securely access data shared within the private local network. The TS-873U can also be used as a VPN Client to connect to other VPN servers or virtual private network through PPTP and OpenVPN for secure data transmission. VPN Client also allows your NAS to connect to multiple servers at the same time. You can connect your devices to your NAS and the VPN server at home to access data on the LAN; via VPN Client on your NAS you can connect to international VPN servers for accessing regionally-restricted services such as Netflix and Hulu in HD Station.
Fast data filing and searching to double your productivity
The TS-873U provides Qfiling and Qsirch for effortlessly organizing and searching for files, providing you with a highly-efficient data storage center. Qfiling automates file organization - simply determine filing conditions, set a schedule, and files will be organized and archived based on your settings. The Qsirch full-text search tool features quick file searching and supports thumbnail previews, content abstract, keyword hints, and more. Both apps provide huge productivity boosts that greatly reduce the time spent looking for files on the NAS, allowing you to focus on other tasks.
Centralized email and contact management for improved communication workflows
It can be hard to manage emails and contact information that are scattered across multiple computers, devices, and accounts - not to mention if important emails or contact information are lost or become inaccessible due to account closure or device malfunction/loss. QNAP QmailAgent and Qcontactz helps you centrally store and manage emails and contact information, making them accessible to all of your devices at any time - and with the powerful Qsirch search engine, you can easily find specific contacts and emails whenever needed.
Comprehensive surveillance solution providing 24/7 security
Surveillance Station is a professional network surveillance Video Management System (VMS) that offers a user-friendly management interface, over 3,000 compatible IP camera models, and expandable IP camera channel licenses. It supports real-time monitoring, video & audio recording and playback with a wide range of customizable settings.
