Version history is a feature of cloud storage that keeps a record of every saved change made to a file. Each time you or someone else edits and saves the file, the service stores a new version. You can then look back at earlier versions and restore one if you need to.
This is useful when a mistake has been made, such as deleting a whole paragraph of your history essay by accident and saving the file. Instead of retyping everything, you open the version history, find the version from before the deletion, and restore it. The same applies if a collaborator makes an unwanted change, like replacing your carefully chosen image with a different one.
When you restore an old version, the service does not delete the newer versions. Instead, it creates a new version that matches the old one, so your version history stays complete. You can usually see a list of versions with dates, times and the names of the people who edited the file.
| Version | Saved by | Change |
|---|---|---|
| 1 | You | First draft of the poster text |
| 2 | You | Added a paragraph about the school garden |
| 3 | Your partner | Deleted the paragraph by mistake |
| 4 | You | Restored version 2, so the paragraph is back; versions 1 to 3 are still listed |
