I have a bash script to achieve this from commandline. Just run it and grab a copy when it makes a staging site. Email me when you are interested.

Hi Michel, you can currently achieve something like this using the shop importer tool in the control panel and a second Hypernode (we now have Hypernode Development plans which are great for this). You can run the shop importer to import a shop from one Hypernode to another Hypernode with one click after filling in the SSH credentials of the production Hypernode. Then you can use the copied shop as a staging environment. You can find the importer tool (the Webshop importeren button) in the control panel under the 'Instellingen' tab.
