Run Qsync as a Windows Service with AlwaysUp

How to Install QNAP Qsync as a Windows Service with AlwaysUp

Automatically start Qsync immediately when your server boots and keep it running 24/7. Ensure that your important files are always synchronized


Last Updated on July 10, 2026

QNAP's Qsync utility supports easy file synchronization across multiple devices. The Windows version establishes a shared folder where all your important files and folders are available.


To install Qsync as a Windows Service:

  1. If necessary, download, install and configure Qsync Client.

    Install and Setup Qsync Client

  2. Download and install AlwaysUp, if necessary.

  3. Start AlwaysUp.

  4. Select Application > Add to open the Add Application window:

    Add Application

  5. On the General tab:

    • In the Application field, enter the full path to the Qsync executable. By default, Qsync is installed in your Program Files folder so you will likely find it at:

      C:\Program Files (x86)\QNAP\Qsync\Qsync.exe
    • In the Start the application field, select Automatically, but shortly after the computer boots. That tells AlwaysUp to launch Qsync 1-2 minutes after a reboot — after critical Windows Services (such as event logging and networking) have fully initialized and are ready to go.

    • In the Name field, enter the name that you will call this application in AlwaysUp. We've stuck with the default of Qsync but you can specify another value you like.

  6. On the Logon tab, enter the user name and password of the Windows account where you installed and setup Qsync. Qsync should run in this account to find its configuration/settings.

  7. Move to the Startup tab and check the Ensure that the Windows Networking components have started box. This informs AlwaysUp that Qsync needs the TCP/IP networking stack to operate.

    We also recommend checking both the Stop all copies of the application running on this computer and Also whenever the application is restarted boxes. These options will ensure that another copy of Qsync won't prevent the instance launched by AlwaysUp from starting properly.

  8. We're done configuring Qsync as a windows service so click the Save button to record your settings. In a couple of seconds, an application called Qsync will show up in the AlwaysUp window. Since it's not yet running, the state will be "Stopped":

    Qsync Windows Service: Installed

  9. Almost done! Now that Qsync will start when your computer boots, let's disable its "launch at login" setting. To do so:

    • Start Qsync normally on your desktop

    • Click Settings in the upper right

    • Move to the Personal tab

    • Uncheck the Launch Qsync on system startup box

    • Click Apply to save your change

    • Click Cancel to exit

    Disable Qsync Launch at Startup Setting

  10. To launch Qsync as a windows service from AlwaysUp, choose Application > Start "Qsync". The State column should transition to "Running" after a few seconds:

    Qsync Windows Service: Running

  11. That's it! Next time your computer boots, Qsync will start up automatically, before anyone logs on.

    We encourage you to edit Qsync in AlwaysUp and check out the many other settings that may be appropriate for your environment.

    For example, setup email notifications, add a "sanity check" to detect network failures, or periodically restart Qsync to cure memory leaks.
