Backups and Restores with Snapshot Pro

Hello,

I just installed Snapshot Pro on my site homeofmissingpeople.org.za

I've been trying to find out how to backup my site with the plugin but I can't can get an answer at page on this link: https://premium.wpmudev.org/project/snapshot/

Can you please tell me exactly how to backup and restore a wordpress site using Snapshot Pro?
