# Loading Backup Copies of a Grade

As you save a grade, you can have Lustre save a copy of it each time you click Save. These copies are then available in case you need to revert to a previous version. The date and time of the save is provided to help you identify the version you want to load.

NoteTo save backup copies of grades, you need to first enable the History button when configuring the user. See System & Menu Settings.

To revert to a backup copy of a grade:

1. Make sure the grade for which you want a backup copy is loaded. See Loading Grades for a Cut.
2. In the Grade menu, click History.

   The Grade History list appears. This is a list of backup copies of the currently loaded grade.

3. Click the backup version you want to load.

   The backup grade is loaded.
