Review Comment:
The `backupAndEraseChunks` method would only throw exception if the erased
data index is out of bound. This is only true for the newly added value set.
Adding LambdaTestUtils.intercept() fails the tests for other parameterized
values since LambdaTestUtils.intercept() @throws AssertionError if the
evaluation call didn't raise an exception.
