It is pretty straightforward, you just need to reverse the source and destination in the faq. Ignore step 16, it doesn't apply.

One advantage of the "push" backup is that the source NAS will make a snapshot, and then back up the snapshot. That ensures that all the files are coherent (copied at the same time instant), and that a file can't change while it is being backed up.
If the backup NAS is on a power schedule (as mine are), then the "pull" backup ensures that the backup NAS is actually running when the backup starts, and that it won't shut down until the backup is finished.

Thanks for clarifying! I plan to use hard drive spin down but not a power schedule so I think push would be okay.
