Quick question

Quick question regarding SnapShot Pro. I currently have Vaultpress and its been amazing (although I've only used it once). I would much rather use WPMUDEV, something that is included in my account. However, I'm going to need more than 10gb of space. Our website currently is running about 30-40gb of data (including media) and is growing. Is there an option to increase storage space? How have people transitioning from VaultPress to Snapshot Pro responded?
