Recover an earlier file version without losing the current one

An older version may contain a missing section, while the current file contains useful new work. Protect both before deciding which one should become current.

1. Save a separate copy of the current file in an appropriate location. For a shared document, coordinate the recovery with other editors so changes do not collide.
2. Open the service's version history and inspect the available timestamps. In OneDrive, version history can restore earlier versions, but availability depends on the account and its settings.
3. Preview or download the likely version when the service allows it. Check the actual missing content rather than choosing solely by the date.
4. Restore only after confirming the intended version and destination. If only one section is needed, consider copying that section into the current document instead.

Open the resulting file and verify the recovered material and recent changes. Version history is useful, but it is not a substitute for a separate backup.
