OneDrive for Business has become the standard for many businesses in cloud storage and as collaboration paltform. OneDrive for Business provides all the functionality of PowerPoint, Word, Excel and most other Office 365 applications. But how to integrate, migrate, synchronize and back up your OneDrice for Business data with external applications? We show you how simple business data integration can be. 

Data integration and synchronization made easy

If you haven't already tried Layer2 Cloud Connector, it's time to take the first step towards effortless connectivity. Start your Layer2 Cloud Connector trial and experience how easy it can be to connect OneDrive for Business to a NAS.

Step 1 - Configure your OneDrive

Open your SharePoint Online, navigate to the top left corner from the page and open the apps tab. Click on the OneDrive icon.

First, click the cogwheel icon on the top right corner to open the settings menu.

In the bottom left corner, look for the "Return to Classic OneDrive" option, as presented in the screenshot, and select it.


Next, navigate to the directory you want to connect to and copy the URL from your browser, which typically looks like this:

Step 1 OneDrive connection setup

Step 2 - Configure the Layer2 Cloud Connector - Create a new connection

Create a new connection by using the Create New Connection option in the Actions pane (right-hand side). The new connection will appear at the bottom of the Connection Manager List (left-hand side). Click on your newly created connection to open the connection configuration settings.

Choose a meaningful name for your connection and replace the current "New Connection" Connection Title with it.

Connections to OneDrive can be bi-directional. An initial connection should always be uni-directional to assure that both data entities are identical before switching to bi-directional. Therefore, choose Left to Right as Direction. You can change this setting after your initial synchronization finished successfully.

Step 3 - Configure the Data Entity 1

We will now set up our Data Entities. Go to the data entity “Data Entity 1” to open the configuration settings.


Choose a Data Entity Title. It is recommended to give your entities meaningful names to maintain an overview when you decide to set up multiple connections.


Select the Data Provider for SharePoint from the data provider list. You can search for SharePoint by typing into the selection box.

Step 2 OneDrive integration source setup




For the Connection String, we need the in step 1 mentioned information. You can copy the connection string at the right and adjust it to match your gathered information.

Use the Verify Connection String option to evaluate if the provided connection string is valid.

  • "URL=https://urlfromstep1;" this property defines the URL of your OneDrive folder you want to synchronize to.
  • "Authentication=Microsoft_Modern;" this property will determine the authentication method used. Microsoft_Modern is the default authentication method to access Microsoft Office 365 / SharePoint Online. This method will not work in case of federation, e.g. ADFS. For further authentication method you can consult the provider specifications linked above.

To check if all necessary columns are received, you can use the Preview Data option on the right-hand pane which will provide you with a pop-up window showing your sample data from your OneDrive entity.

Step 4 - Configure the Data Entity 2

We are going to send the data to a NAS-system. You need the address to a folder in the NAS-server you want to send the data to. You can get this information from your network administrator. This address would be like this:



Use the left-hand pane to switch to the data entity "Data Entity 2". We will be using the File System Provider for this setup. 


You can copy the below Connection String which contains the minimum of required properties to connect to your folder on the NAS-server.




  • "Directory=path;" this property points to the folder in your file server you want to synchronize data to.

Next, we will configure our mapping settings. Click on the Mappings option on the left-hand pane. If your fields from SharePoint are named identical to the fields from your source system, the Enable Auto Mapping option will match those columns. Disabling this option allows you to match your columns as needed. We enabled auto-mapping in our setup. Save your changes by using the right-hand pane option Save Changes.

Step 5 OneDrive data integration start

Step 5 - Running your connection

To run your connection switch back to the main connection configuration node and use the Run Now Button located on the bottom of the setup page. The Run Synchronization Toolbox will also display the synchronization process.

This is a data preview of the information we have accessed in our source entity.

This will be the result in our NAS server after our initial successful synchronization.


If you want to use a bi-directional syncronization, you can now switch your connection directon after our first initial synchronization run finished successfully.


We also recommend to choose a Conflict Resolution that matches your enviroments needs. You can find out more about the different conflict resolutions in our Layer2 Cloud Connector User Documentation.

Hints and known issues

Connection direction

As far as tested, this connection supports uni-directional as well as bi-directional synchronizations. After adjusting the direction to bi-directional, you should check your Mappings settings again because some systems might include read-only columns that cannot be mapped directly. We also recommend to choose a Conflict Resolution that matches your environments needs. You can find out more about the different conflict resolutions in our Layer2 Cloud Connector User Documentation.


Other libraries or lists

If you want to use another library in your OneDrive, you can get the correct URL by navigating to the location, opening the List/Library Settings and looking at the "Web Address:" given at the top of the settings page. That is the URL you will need for the connection string to this location. If you are having trouble finding other content in your OneDrive location, you can click on the Cog-like icon near your account name in the upper-right corner and select Site settings from the list of options. Then under "Site Administration", select Site libraries and lists, which will show all items currently in the OneDrive as well as allow you to create new ones. The site content may also be listed in the left column of that page, if your UI configuration allows it.


SharePoint list attachments

SharePoint list attachments are not managed at this time and are not supported.


File size

OneDrive fo Business supports files up to 2GB. Larger files will be rejected.‚Äč (See SharePoint Online software boundaries and Limits for more information.)
