 # Point-in-time snapshot
 
-Azure App Configuration maintains a record of changes made to key-value pairs. This records forms a complete timeline of key-value changes, beginning with the creation of each pair, for up to 7 days. An App Configuration store can reconstruct the history of any key-value and provide its past value at any given moment. Using this feature, you can “time-travel” backward and retrieve an old key-value. For example, you can recover configuration settings used prior to the most recent deployment in order to roll back the application to the previous configuration.
