How to Back Up Known Folders from Multiple Computers to OneDrive Without Merging
Question details
The user wants to back up Windows Known Folders (like Desktop and Documents) from multiple computers to a single OneDrive account without the files merging across devices.

- Product
- Microsoft OneDrive
- Device & OS
- Windows
- Scenario
- Attempting to create separated, one-way backups of user folders from several PCs to the cloud using a single Microsoft account.
- Observed behavior
- OneDrive's Known Folder Move feature synchronizes files across all devices logged into the same account, resulting in files from different computers merging together.
Verify your current OneDrive storage capacity to ensure it can accommodate the total data size from all your computers, and determine whether you strictly require separate backups or can adapt to a unified, synchronized file system.
Manually Back Up Files to Device-Specific Folders
Avoid automated merging by manually organizing your files into unique OneDrive folders assigned to each computer.
Because OneDrive is fundamentally designed to sync rather than provide separate one-way backups, the most reliable native method to keep files separated is bypassing the automated Known Folder Move and manually organizing your data.
Navigate to the OneDrive folder on your computer using File Explorer, or sign in to OneDrive through your web browser.
Create a new folder and name it clearly after the computer you are currently using (e.g., 'Laptop_Backup' or 'Office_PC_Desktop').
Manually copy and paste, or drag and drop, the files from your Desktop and Documents folders into this newly created device-specific folder.
Perform this exact process on your other computers, ensuring you create a uniquely named folder for each device.

Use Separate Microsoft Accounts
Ensure complete separation of computer backups by using a different Microsoft account for each device.
Utilize a Dedicated One-Way Backup Tool
Use third-party backup software that supports strict one-way syncing to separate folders within your OneDrive directory.

Frequently Asked Questions
Why does OneDrive merge my Desktop files across different computers?
OneDrive's Known Folder Move feature is fundamentally designed to synchronize user data across all devices signed in with the same Microsoft account. It treats the Desktop and Documents folders as unified workspaces, which is why files from different computers merge together.
Can I set up a one-way backup natively in OneDrive?
No, OneDrive does not offer a native one-way backup option for Windows Known Folders. It operates on a two-way synchronization model. To achieve a one-way backup, you must manually upload files via the web interface or use dedicated third-party backup software.
Will pausing OneDrive sync prevent my files from merging?
Pausing the sync or temporarily signing out will temporarily stop files from uploading or merging. However, as soon as you resume sync or sign back in, OneDrive will compare the local and cloud directories and merge the files again. It is not a dependable long-term strategy for keeping backups separate.
