 ===== Data Retention Policy =====
-Snapshot takes an incremental backup of the Big Data state. Incremental means each snapshot is dependent on the others that have gone before it. The Snapshot and Restore process will become inefficient if too many snapshots are maintained. Therefore, it is advised you have an archiving and data retention policy in place.

-===== Safely Removing Snapshots =====
+===== Safely Removing Snapshots / Purge Command =====
+Snapshots can be removed using the Backup Utility and executing the **Purge** command. This will delete old snapshots according to the retention policy defined in the config file.
+The default snapshot retention is 14 days.
+To modify the retention policy:
+. Open the BackUp Utility config file. \\ For a default installation, the config file is located:
+<code>C:\Program Files\Intelligent Plant\Big Data\BackupUtility\BackupUtility.exe.config</code>
+. Refer to  **AppSettings** section and modify **DayRetentionPolicy** setting.
+<code>
+  <appSettings>
+    <add key="BigDataUrl" value="http://localhost:9200"/>
+    <add key="log4net.Internal.Debug" value="false"/>
+    <add key="DayRetentionPolicy" value="14"/>
+  </appSettings>
+</code>
+. Save file \\ The new setting will take effect the next time the BackupUtility is started.
