The QNAP RM-IR004 remote control (sold separately) can be configured using QButton to customize the actions of individual buttons, providing a more convenient NAS experience.

Multiple ways to enjoy your multimedia
QNAP provides a wide range of multimedia applications for you to easily enjoy photos, music, and videos.

- Cinema28 allows for single-interface management of all your media files and can stream files to every connected device throughout your home.
- QVHelper allows users to stream media files or music playlists from a QNAP NAS to VLC player.

Protect important data with snapshots
Snapshots help protect your data by fully recording the NAS system state and metadata. If files are accidentally deleted or modified or the system is afflicted by ransomware, you can use snapshots to quickly restore files to a previously-recorded state. QNAP snapshots are block-based and only record the changed data. Not only does this save storage space but also reduces the time required to back up and restore data. The TS-251B supports up to 1,024 snapshots per NAS and up to 256 snapshots per volume or LUN.

Consolidated notifications and extra NAS security
QTS 4.3.5 provides various mechanisms to ensure the data saved on your TS-251B is carefully safeguarded, including the brand-new Notification Center that consolidates system logs and notifications into a single app and the Security Counselor that checks for weaknesses and offers helpful security recommendations.

Notification Center
Consolidates system logs and notifications for all NAS apps into a single app with flexible rule settings, facilitating smooth and easy NAS management.

Security Counselor
Checks for weaknesses and offers recommendations to enhance NAS security. Anti-virus and anti-malware software is also integrated within Security Counselor to ensure the complete protection of your NAS and data.

Automate everyday tasks with IFTTT Agent
QNAP IFTTT Agent integrates the popular web automation service IFTTT (If This Then That), allowing you to create a near-unlimited number of automated workflows. Simply connect your IFTTT account with your TS-251B and set triggers and actions. For example, if you set a trigger as “Any new photo on the phone” and the action as "Upload the photo to QNAP NAS," then all the photos taken using your phone will be automatically uploaded to TS-251B.

Multiply your productivity
The app-driven QTS operating system provides solutions for simplifying file backup, management, search, and more. With File Station you can view and manage your files from NAS and multiple storage devices; the OCR Converter allows you to extract text from images; Qfiling helps automate file organization, and Qsirch helps quickly find files.

Centralized File Management
Use File Station to directly access files on USB devices - including optical disc drives. Files from different devices can be easily viewed and managed on a single interface.

File Digitization
OCR Converter extracts text from images, helping to boost productivity and making it easier to find files.

Smart Filing
Qfiling automates file organization. Files are automatically archived into folders based on your settings.

Qsirch quickly finds images, music, videos, documents, emails, and other files.

Multi-point file backup, access and sync
The TS-251B centrally stores data and files, and supports SMB/CIFS, AFP and NFS protocols for file sharing across Windows®, Mac®, and Linux®/UNIX® devices. 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-251B will be made available for all linked devices, such as computers, laptops and mobile devices. Hybrid Backup Sync can help you easily backup or synchronize data on the TS-251B to other QNAP NAS, remote servers, or cloud storage for easy disaster recovery.

QVR Pro safeguards your environment

Virtualization Station
Virtualization Station allows you to run multiple Windows®, Linux®, UNIX® and Android™ virtual machines on the TS-251B. You can use Virtual Network Computing (VNC) through a browser to operate the virtual machines. Virtualization Station is ideal for organizations to run multiple applications on a single NAS.

Container Station
Container Station integrates LXC and Docker® lightweight virtualization technologies. You can download apps from the built-in Docker Hub® to easily import/export container apps and manage access controls, enjoying the benefits of easy installation, transferability and high-efficiency.

Flexible and economical storage expansion
You need an easy solution to increase storage capacity when running out of space. QNAP provides several ways to expand your NAS storage as needed to accommodate data and business growth.

Upgrade RAID Capacity
Hot swap lower-capacity drives with larger-capacity drives so that your QNAP NAS can grow with your business.
