Fix QNAP HBS Sync Failures for Large Files on OneDrive
Question details
The user needs to understand why a 118 GB file fails to sync to OneDrive for Business via QNAP HBS, and how to successfully upload it.
- Product
- OneDrive for Business / QNAP HBS
- Device & OS
- not provided
- Scenario
- Attempting to sync or back up a large data file from a QNAP NAS to OneDrive using the Hybrid Backup Sync (HBS) application.
- Observed behavior
- The file sync fails with a size limitation error, even though the file is 118 GB and Microsoft officially supports OneDrive file sizes up to 250 GB.
Verify the exact size of your file and ensure your OneDrive for Business account has sufficient total storage capacity available before attempting another upload method.
Bypass QNAP HBS Limits by Uploading via Web Browser
Since the file size limitation is enforced by the QNAP HBS cloud connector rather than OneDrive itself, uploading directly through the browser bypasses this restriction.
Microsoft officially supports individual file uploads up to 250 GB for both standard OneDrive and OneDrive for Business. When using third-party NAS applications like QNAP HBS, the software's API connector may impose lower limits based on job configurations or device constraints.
Open your preferred web browser, navigate to the OneDrive for Business website, and log in with your Microsoft credentials.
Access your NAS via your computer's local network (e.g., through File Explorer or Finder) to locate the 118 GB file.
In the OneDrive web interface, click the 'Upload' button, select 'Files', and choose the large file from your network drive to begin the direct upload.
Use the Official OneDrive Desktop App
Utilizing the official OneDrive desktop client ensures full compatibility with Microsoft's 250 GB file size limits and offers better resume capabilities for large transfers.
Boost Your Productivity with WPS Office
While you manage your network storage and OneDrive syncing tasks, consider using WPS Office for your daily document needs. It's a highly compatible, free alternative to Microsoft Office that saves local storage space and integrates seamlessly with cloud environments.
Frequently Asked Questions
What is the maximum file size for OneDrive for Business?
Microsoft officially supports a maximum individual file size of 250 GB for both personal OneDrive and OneDrive for Business, provided your account has sufficient overall storage space.
Why does QNAP HBS fail to sync my 118 GB file to OneDrive?
QNAP Hybrid Backup Sync (HBS) relies on specific API cloud connectors that often enforce their own file size limitations, independent of OneDrive's official capacity. This is a known limitation on the QNAP side.
Does the upload method affect OneDrive file size limits?
Yes. While the backend limit is 250 GB, certain third-party applications, outdated browsers, or legacy APIs might struggle with extremely large files, causing the upload to timeout, fail, or hit artificial limits.
How can I check if the limitation is on my NAS or OneDrive?
The easiest way to test this is to upload the same file directly to OneDrive using a modern web browser or the official OneDrive desktop app. If it succeeds, the limitation is strictly within the NAS application.
