Can OneDrive for Business Sync Files from Another Cloud Service?
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.
Before you start

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.

1
Download from Source Cloud

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.

2
Access OneDrive for Business

Open your web browser, navigate to office.com, sign in with your business credentials, and open the OneDrive application.

3
Upload to OneDrive

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.

Storage Limits: Keep an eye on your local hard drive space when downloading large batches of video files. You may need to transfer them in smaller batches to avoid running out of local storage.

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.
