The easiest way to do this is to create another Cassandra DC and point Spark to it, since Spark can operate directly on data in Cassandra. No impact on C* performance and no complex backup/restore process required, just let Cassandra replicate the data for you.
If you need a scalable bulk export/import solution on your production data that doesn't affect C* performance I would look at doing something like this: https://www.youtube.com/watch?v=eY5oSZnwmJg . It's the best solution I've seen to the problem.
