# Use the Pentaho Upgrade Installer to restore a backup

You can use the Pentaho Upgrade Installer to restore a backup that was created during the upgrade process. The following instructions describe the user interface that opens and guides you through the process for restoring a backup generated from a previous upgrade of Pentaho products from an earlier version to version 9.3.

**Note:** Verify that the JAVA\_HOME environment variable is set to the current version of Java that you have installed on your machine before starting the Pentaho Upgrade Installer.

Perform the following steps to restore a Pentaho Upgrade Installer backup of your earlier version of Pentaho products.

1. Exit out of any Pentaho products you currently have running.

   If you are upgrading your Pentaho Server, stop the server. For instructions, see [Start and stop the Pentaho Server for configuration](/install/9.3-install/pentaho-configuration/tasks-to-be-performed-by-an-it-administrator/configure-the-pentaho-server/start-and-stop-the-pentaho-server-for-configuration.md).
2. Run the update executable file you downloaded from the [Support Portal](https://support.pentaho.com/hc/en-us). After processing, the Pentaho Upgrade Installer interface opens to the Introduction window.
3. Click **Next**
4. In the License Terms window, read through the license agreement and select the check box to acknowledge the terms, as shown in the following example:

5. Click **Next**.
6. In the Welcome window, select **Restore** to restore your Pentaho products and click **Next**.

8. Click **Next**. You are prompted to confirm you are replacing the current installation with the selected backup.

   After installation and configuration updates, the upgrade installer indicates Restore Complete. If errors occur, examine the log files for details about how to resolve the error. Depending on the error, you may need to contact your customer support representative for help. The default location of the log file is `<*root installation directory*>/*Pentaho\_\_Installation*/logs`.
9. Click **Done** to exit the Pentaho Upgrade Installer.
10. If you are upgrading your Pentaho Server, [restart the Pentaho Server](/install/9.3-install/pentaho-configuration/tasks-to-be-performed-by-an-it-administrator/configure-the-pentaho-server/start-and-stop-the-pentaho-server-for-configuration.md).
