I wrote a few iPhone apps using Core Data for persistent storage. Everything is working great but I would like to add the ability for users to back up their data to a PC (via WiFi to a PC app) or to a web server.

This is new to me and I can't seem to figure out where to begin researching the problem. I don't want to overcomplicate the issue if there is an easy way to implement this.

Is anyone familiar enough with what I am looking to do to point me in the right direction or give me a high level overview of what I should be considering?

The data is all text and would be perfectly stored in .csv files if that matters.
