# Restore a deck to an earlier revision

[Canonical article](https://slides.com/docs/revision-history)

Revision history lets you preview and return to an earlier version of your deck, so you can experiment freely and recover from mistakes. Slides saves a new revision each time your deck is updated and keeps revisions for six months.

## Browse revisions

Open **Revision history** (the clock icon) in the editor sidebar to see the available revisions. Each revision has two actions:

- **Preview** opens the deck as it appeared at that point in time.
- **Restore** rolls the deck back to that revision. Newer revisions remain available in case you change your mind.

## Restore a single slide

When previewing a revision, you can restore the entire presentation or only the slide currently in view.
