How to back up data from Windows computer to Synology NAS using Windows or 3rd party applications


Synology NAS could serve as the backup center for office or home PCs. With the help of the backup application installed on your PC, automated backup can be performed in the background, and files backed up to your Synology NAS can be saved in versions, allowing you to restore a specific version of backup data in case of unexpected data damage or loss.

This article will guide you through the process of setting up backup and restoration tasks between PCs and your Synology NAS using the backup application that comes with Windows. If you would like to use third party backup applications, some hints are also provided at the end of this article to help you get started.


  1. Before you start
  2. Back up and restore with Windows 7
  3. Back up with Third Party Applications

1. Before you start

This article assumes that you have done the following tasks for your DiskStation:

  • Hardware installation for Synology DiskStation.
  • Software installation for Synology DiskStation Manager (DSM, web-based operating system of DiskStation)
  • Creating volumes and shared folders (See here)
  • Creating DSM local users who are granted permission to access the shared folders(See here)
  • Accessing your DiskStation within the Intranet from Windows (See here)

Refer to Quick Installation Guide for more information about hardware and software installation. You can also see Synology DiskStation User's Guide (available at Synology's Download Center) for a general idea about topics related to this article.

2. Back up and restore with Windows 7

Synology DiskStation supports the backup application that comes with your Windows. In this section, we will guide you through the process of backing up PC data to your DiskStation with Windows 7. For more information about backing up your data with other versions of Windows, visit Microsoft Support and search "back up files" or "restore files" for related tutorials.

  • To back up with Windows 7, make sure you are using the Ultimate, Professional, or Enterprise version.
  • For the list of Windows that have been verified to be able to back up PC data to your DiskStation, please click here.

To back up PC data with Windows 7:

  1. Follow the instructions in this Microsoft Support article to launch Backup and Restore and configure automatic backup from Windows 7 to your DiskStation.
  2. When you are prompted to select a location to save your backup, click Save on a network to locate your DiskStation on the local area network.
  3. In the window that appears, enter \\Synology_Server_Name\Shared_Folder_Name or \\Synology_Server_IP\Shared_Folder_Name, and then authorize using the credentials of a DSM user who has the "Read/Write" privilege to the specified shared folder.
  4. Click OK and follow onscreen instructions to complete the setup.
  5. Note:

    Since Windows7's Backup and Restore will create a system image along with your backup data on the DiskStation, it might take a while to create the first backup. Subsequent backup tasks will take much less time because only new or changed information will be added to the backup data.

To restore backed up data to your PC:

Follow the instructions in this article to find and select the files you want to restore, and then restore the files to your PC.

3. Back up with Third Party Applications

Synology DiskStation has been verified to act as the backup destination for a number of third party applications. Visit here for the list of verified applications. However, before using any of the applications, please note that the complexity of setting up those applications may vary. See below for the differences:

  • Applications designed for larger corporations, such as Symantec Backup Exec and CA ARCserve, require a more complicated network configuration. IT professionals will need to designate a Windows Server (for example, Windows Server 2008) as the administration server, which centrally manages Windows clients within the ADS domain to perform backup tasks to the DiskStation.
  • Other applications on the list require a simpler network configuration. As long as the PCs and the DiskStation are all functioning and within the same local area network, you can install any of those applications on the PCs, and then back up PC data to the DiskStation.
