+   Wait for the Queryable Snapshot to mount before you
+   continue. Snapshot mount time depends on the size of the
+   snapshot. Verify the snapshot is mounted by navigating to
+   :guilabel:`Continuous Backup` and selecting the :guilabel:`Restore
+   History` tab. When the snapshot is mounted, the :guilabel:`Status`
+   column reports the date and time of the mount operation.
