# Snapshots

Every time you change a map in SpecMap, a snapshot of the map is stored. You can restore these snapshots if you realise you want to undo your changes. A total of 10 snapshots are stored:

- The 5 most recent changes to the map are stored as separate snapshots.
- An additional snapshot is taken every 5 changes, and 5 of these less frequent snapshots are also stored.

## Restoring a Snapshot

To restore a snapshot:

1. Locate the map whose snapshot you want to restore in the list, and click on ... to open the menu.\

1. Click on **Restore this version** next to the snapshot you want to restore.
1. The map is restored and added to the list of maps, including the time stamp of the snapshot:\
