Is QNAP a file server?

QNAP is a brand name for a series of network-attached storage (NAS) devices produced by QNAP Systems, Inc. QNAP NAS devices can be used for a variety of purposes, including as file servers for data storage and sharing.

What is a file server?

A file server is a dedicated network storage device that allows users to store, access, share, and manage data and files from a centralized location. File servers connect to local area networks and allow users to share files across different clients like desktop computers, laptops, and mobile devices. The main functions of a file server are:

  • Centralized storage – Store files and data in one centralized location instead of saving them locally on individual computers.
  • File sharing – Allow authorized users to access shared files and folders from different devices on the network.
  • File security – Control user access permissions and prevent unauthorized access.
  • File backup – Automate backups to prevent data loss.

Some common examples of file server platforms and devices include Windows Server, Linux servers, UNIX servers, and dedicated NAS (network-attached storage) appliances like QNAP and Synology.

Key features of QNAP NAS devices

QNAP NAS devices run the QTS operating system and have many features that make them capable network file servers:

  • File sharing protocols – Support SMB, CIFS, AFP, NFS, FTP, WebDAV for file sharing and collaboration.
  • Centralized storage – Offer high capacity storage with support for multiple hard drives.
  • RAID configurations – Support RAID 0, 1, 5, 6, 10 for storage redundancy and protection against drive failures.
  • Snapshots – Allow schedulable snapshots for backing up shared folders.
  • User permissions – Assign fine-grained folder and user access permissions.
  • Encryption – Offer AES 256-bit volume encryption for secure data storage.
  • Network protocols – Support standard TCP/IP networking for integration into LAN environments.
  • Remote access – Allow remote file server access over the internet.
  • Virtualization support – Allow deploying virtual machines and containers for advanced applications.

These built-in features make QNAP NAS units fully capable of serving as dedicated file storage and sharing servers for small businesses, workgroups, and home users. The ability to centrally store data and flexibly share it over the network positions them as true file server solutions.

What types of QNAP NAS models are available?

QNAP has a wide range of NAS models targeted at different users and environments:

QNAP NAS Series Description
TS-x31K Series Entry-level home and SOHO NAS models.
TS-x51 Series Mid-range NAS models for SMBs.
TS-x53 Series High-performance business NAS models.
TS-x77 Series Advanced rackmount NAS for enterprises.
TVS-x72X Series NAS models optimized for video surveillance and IP cameras.
TES-x85 Series Enterprise-grade all-flash SSD NAS.

Within each series, there are multiple models that offer different hardware specifications like processor types, number of drive bays, memory capacity, network interfaces etc. This allows choosing a NAS tailored specifically for budget, performance needs, and scale. All models can be deployed as file servers.

What are the software features of QNAP NAS?

QNAP devices run the proprietary QTS (QNAP NAS Operating System) software which is a Linux-based operating system optimized for NAS applications. Key QTS features that enable file server functionality include:

  • File Station – Provides a centralized file management interface to manage files on the NAS through a web browser.
  • Shared Folders – Allows creating network shares and configuring SMB and AFP permissions.
  • Windows ACL – Provides fine-grained Windows ACL permissions on network shares.
  • Quota Management – Allows setting quota limits on storage usage for users and groups.
  • Antivirus – Provides real-time scanning of files uploaded to the NAS.
  • Backup Tools – Allows backing up files from NAS shared folders to external drives.
  • Cloud Storage Gateways – Allow syncing or backing up NAS files to cloud services like Amazon S3, Azure, Dropbox etc.
  • Version Control – Retains multiple versions of files for data protection.
  • Data Replication – Allows replicating data between QNAP NAS units.

These built-in services and many more enable administrators to fully manage QNAP NAS devices as feature-rich file server and storage solutions.

What are the advantages of using a QNAP NAS as a file server?

The key benefits of deploying a dedicated QNAP NAS as a file server are:

  • Improved file availability and access – Files stored centrally on the NAS are available from anywhere on the network.
  • Better security – Server-grade OS, encryption, access controls and versioning improve security.
  • Scalability – NAS capacity can be expanded by adding more HDDs or SSDs.
  • Shared storage for collaboration – Teams can store, share and collaborate on common files.
  • File backups – Server-grade backup tools like snapshots protect against data loss.
  • High reliability – RAID storage, redundant components, failover provide high uptime.
  • Easy management – Web-based UIs make NAS easy to manage as servers.

Compared to direct-attached storage or cloud servers, QNAP NAS devices offer more cost-effective and customizable on-premise file servers and shared storage for SMBs.

What are some use cases for deploying QNAP NAS as file servers?

Small business file server

QNAP NAS models like the TS-x31K are ideal for small businesses to set up as an on-premise file server for daily file storage, backup, sharing, and print services.

Team collaboration

Larger QNAP NAS models like TS-x53, TS-x77 can provide centralized file storage for collaborative team workspaces, hosting documents, graphics, videos and other files teams need to access and work on collectively.

Departmental file shares

Organizations can provision separate file shares on the NAS to serve as departmental file servers for groups like marketing, sales, HR etc. Access can be locked down to allow only department members to access their own file share.

Remote office file server

QNAP NAS devices lets organizations set up a remote office file server that replicates files to the central headquarters or data center for backup. Local office users get better LAN access speeds while gaining offsite protection.

Media files repository

The high storage capacity, transcoding abilities, and media streaming features of QNAP NAS models like TVS-x72X allow hosting large collections of media files like photos, videos, music in a centralized location for easier sharing and distribution.

What should you consider when selecting a QNAP NAS file server?

Some key considerations when choosing a QNAP NAS for file server applications include:

  • Storage needs – Choose a model that can accommodate current and future storage growth via extra drive bays, expansion units.
  • Network type – Confirm the NAS model has sufficient Ethernet ports, speeds, and optional 10GbE to integrate into your LAN.
  • Protocols needed – Verify NAS supports SMB, AFP, NFS, FTP as required for sharing files to Windows, Mac, Linux clients.
  • User scale – More powerful multicore CPU models can support more simultaneous connected users.
  • Virtualization support – For advanced apps, check if NAS supports hosting VMs and containers.
  • Business continuity – Models with redundant LAN ports, power supplies provide higher uptime.
  • Budget – Get the right balance between cost and key features based on current needs.

Choosing the appropriate QNAP NAS model and storage as per business needs is important to provision an efficient file server.


QNAP NAS devices are full-fledged network-attached-storage solutions that can readily serve as file servers for small businesses, workgroups, and home users. Their strong set of file management, sharing, security, backup, and collaborative features make them versatile for hosting file shares that teams can contribute to and access centrally. Models like the TS-x31K, TS-x51, TS-x53, TS-x77 can be deployed as dedicated file servers with capacities from 2 bays up to 12 bays and even more via expansion units. For SMBs looking to set up a reliable on-premise file server, QNAP NAS appliances provide easy-to-manage solutions that can be tailored to specific storage, performance, and budget needs.
