This is still incorrect. Update1Copy.txt should not be in the result for the search operation either, because it was copied at 2021-07-01T12:15:00, and then deleted in the rollback to 2021-07-01T12:10:00.

Indeed, Update1Copy.txt should also not appear in the search result, since it was uploaded at 12:15, and the rollback was to 12:10.
