Prerequisites

Context

  4. In the upper area of the left function pane, select the snapshot that you want to roll back and choose More > Stop Rollback on the menu bar.

    The security alert dialog box is displayed.

  5. Confirm the snapshot rollback.
    1. Confirm the information in the dialog box, select I have read and understand the consequences associated with performing this operation., and click OK.

      The Execution Result dialog box is displayed, indicating the operation result.
