Question details

The user wants to know if Microsoft OneDrive retains original file creation and modification dates, as files uploaded to the service often appear to have altered timestamps or metadata.

Does OneDrive Preserve Original File Dates and Metadata During Upload?

Product: Microsoft OneDrive
Device & OS: not provided
Scenario: Uploading local documents and images to OneDrive with the intention of using it as a reliable cloud backup.
Observed behavior: Files uploaded to OneDrive sometimes display changed creation or modification dates, and some image files appear to be resized or automatically tagged by the system.

Before you start

Before checking your file metadata, verify whether you are viewing the file properties via the OneDrive web interface or through your local File Explorer, as operating systems and web browsers can display timestamp attributes differently.

Solution 1Recommended

Use OneDrive as a Sync Service, Not a Forensic Backup

Understand how OneDrive manages timestamps and prioritize using the 'Date Modified' attribute over the 'Date Created' attribute.

OneDrive is designed primarily as a continuous synchronization and cloud collaboration tool rather than a strict forensic backup solution. It prioritizes keeping the latest version of a file accessible across all connected devices.

When files are uploaded to the cloud or downloaded to a new device, the local operating system often assigns the 'download moment' as the new 'creation date'. However, the 'modification date' is usually preserved. Knowing where to look can help you verify your file's history.

Check the Modification Date

Open File Explorer and navigate to your OneDrive folder. Right-click the file in question, select 'Properties', and look at the 'Modified' date. This date generally reflects the last time the file's actual content was edited, which is more reliable than the 'Created' date.

Utilize Version History for Recovery

If a file's content or metadata has been undesirably altered during sync, right-click the file and select 'Version history'. You can view and restore previous iterations of the file directly from this menu.

Use OneDrive as a Sync Service, Not a Forensic Backup

Backup Best Practices: If you require exact preservation of all timestamps and Exif data without any alteration, consider using a dedicated backup utility or NAS device instead of a live synchronization folder like OneDrive.

Solution 2

Archive Files in a ZIP Folder Before Uploading

Compressing your files into a ZIP archive prevents OneDrive from interacting with or modifying the individual file metadata.

Frequently Asked Questions

Why does the file creation date change when I download a file from OneDrive?

When you download a file from OneDrive to a new device, your local operating system registers the download moment as the time the file was technically 'created' on that specific hard drive. The 'Date Modified' property, however, is usually retained from the original file.

Does OneDrive compress or resize my uploaded photos?

OneDrive typically stores the original file without compression. However, if you are viewing thumbnails in the web interface or if your mobile device is set to optimize storage (like the iOS 'Optimize iPhone Storage' feature), the images may appear compressed or resized.

Can I stop OneDrive from auto-tagging my uploaded photos?

Yes, you can disable the automatic photo tagging feature. Log into OneDrive on the web, click the Settings gear icon, navigate to Options > Photos, and turn off the auto-tagging setting.

Is OneDrive suitable for a complete system backup?

No. OneDrive is built as a cloud synchronization and collaboration platform. For a complete system image or strict forensic backup where every byte, folder structure, and timestamp must be identical to the source, a dedicated backup software solution is strongly recommended.
