We are building an iOS app with Parse.com, but still can\'t figure out the right way to backup data efficiently.
As a premise, we have and will have a LOT of data store
On December 2015 parse.com released a new dashboard with an improved export feature. Just select your app, click on "App Settings" -> "General" -> "Export app data". Parse generates a json-file for every class in your app and sends an email to you, if the export-progress is done.
UPDATE:
Sad but true, parse.com is winding down: http://blog.parse.com/announcements/moving-on/
