Can OneDrive for Business Sync Files from Another Cloud Service?
Question details
The user is asking whether OneDrive for Business supports direct synchronization of files stored on external, unrelated cloud storage services.

- Product
- OneDrive for Business
- Device & OS
- not provided
- Scenario
- Attempting to send or synchronize external media, such as video files from a Hikvision NVR stored on a different cloud provider, directly to a OneDrive for Business account.
- Observed behavior
- Native OneDrive synchronization only functions with internal OneDrive and SharePoint libraries, failing to directly pull or sync data from third-party cloud services.
Ensure you have sufficient storage space available in your OneDrive for Business account and verify that you have reliable network bandwidth before attempting to transfer large files like NVR videos.
Manually Transfer Files to OneDrive
Since native cross-cloud sync is not supported, manually downloading files from the source cloud and uploading them to OneDrive is the most direct workaround.
OneDrive for Business is designed to synchronize strictly within the Microsoft 365 ecosystem (OneDrive and SharePoint). To move files from a separate cloud service, a manual transfer is required.
Log in to the alternative cloud service where your NVR video files are currently stored. Select the required files or folders and click the 'Download' button to save them to your local device.
Open your web browser, navigate to office.com, sign in with your business credentials, and open the OneDrive application.
Click the 'Upload' button near the top of the screen, select 'Files' or 'Folder', locate the recently downloaded media on your computer, and confirm the upload.
Use Microsoft Power Automate for Cloud Syncing
Automate the transfer of new files between external cloud services and OneDrive for Business using Microsoft's native workflow tool.
Experience Seamless Document Management with WPS Office
While resolving cloud synchronization setups can be complex, managing your everyday office documents shouldn't be. WPS Office is a highly compatible, lightweight suite that helps you handle Word, Excel, and PowerPoint tasks with ease.

Frequently Asked Questions
Can I map my OneDrive for Business as a network drive for my NVR?
Yes, you can map OneDrive or SharePoint as a network drive in Windows. However, for continuous NVR video writing, it is generally recommended to use specialized FTP-to-cloud gateways, as direct continuous recording to a synced folder can cause file lock issues.
Are there third-party tools specifically designed for cloud-to-cloud migration?
Yes, services like MultCloud, Mover.io (now part of Microsoft), or CloudFuze allow you to connect multiple disparate cloud storage accounts and synchronize files between them without downloading the data locally first.
Does SharePoint sync natively with third-party cloud platforms?
No, SharePoint and OneDrive for Business natively sync only with each other. For syncing external platforms, you must rely on APIs, Microsoft Power Automate, or third-party integration software.
