Hi,
There are several approaches to doing 2-up duplex depending if your back side will consist of variable data.
In both cases you need to start with
2 virtual pages. Select the virtual page option on the page under page type.
Then make sure to use the correct page size. This should be the size of each post card.
Then You should have 2 more pages which are normal pages and they will have the N-Up object on the page, calling the front page on one and the back page on the other.
Make sure to add the repetition and select the option "change data with each repeat".
For more on N-up with variable data on both sides
there is an example you can refer to.
