Managed Cloud Backups Status While Running and Space?

You sly dogs! Boy was I surprised when I went to check the change log before updating my Snapshot Pro and saw "New: Beta release of full managed cloud backups!" I was and still am thrilled!

It worked great when I ran it and just have a couple questions.
1. Will there be options to purchase additional storage space?
2. While the backup is running it displays and updates steps. Can I move away from this screen without it interrupting the backup?

I know it is still beta but well done WPMUDEV, well done! I have been looking forward to this.
