# Diagram version history

Diagram history is separate from page history, because a diagram can change many times without the page text changing at all.

## What is kept

| **Recorded** | **Detail**                              |
| ------------ | --------------------------------------- |
| Every save   | A full copy of the source at that point |
| Who saved it | The account that made the change        |
| When         | Timestamp of the save                   |

## Restoring

Open the diagram's history, pick a version, and restore it. Restoring creates a new version rather than deleting anything, so the restore itself is reversible.

## A few things that catch people out

* Diagram history is not page history. Reverting the page does not revert the diagram.
* Retention limits apply on very long histories. See [Reference](https://help.gocapable.com/diagrams/reference.html).
* Deleting the page deletes the diagram and its history with it.
