What happens to the version you restore over
Restoring an older version doesn't delete the version it replaces β that most-recent version simply gets added to the list as one more entry in the history, so you can go back to it again later if the restore turns out to have been the wrong call.
How long OneDrive keeps version history
Version history is typically retained for around 30 days for most files, though the exact window can vary by file type and your specific plan. If a change happened further back than that, it may no longer be recoverable through version history alone, so check your current plan's retention details if you're relying on this for long-term backup.
