This was tested on Final Fantasy XIII which can be viewed below.

Please be aware that PS Now is still only in beta and because of that fact any functionality, game availability, features, and prices may change. Once you have copied your save back out and Playstation Now will restart the game. After selecting Save Data Utility you would leave the game briefly, scroll up to Online Storage, select the game save for your rented game, and then copy it to the PS Now storage. Once you are in the XMB select Save Data Utility. To upload the save you would begin playing the rented game, hit the Playstation button on your Dualshock 4, and then select the Display XMB Menu.

You are able to copy it over because Playstation Now emulates the native PS3 XMB and file system to a small degree. Using the cloud save functionality of Playstation Plus you can upload existing saves to games within Playstation Now.
