I'm a little confused at what you're asking? Are you asking about your PVZ Heros's account or your EA account? In either case, someone correct me if I'm wrong but I don't believe that either will back itself up based on age nor should there be any reason to. The way I understand it, any backups you do will be on your devices end and that would very by platform but non of those would be critical or even matter when it comes to this game. The only thing you need to worry about is loading the game at the current version which when you connect to the internet the app should handle itself. EA will always store your user data such as account name, rank tied to that name with the number of stars you've currently accumulated, cards you've collected and gems/sparks you have. All of the information that would be critical to this game will be stored by them so you don't have to worry about anything. That data is tied to your user name and I would believe is stored on their end which I'm sure has multiple levels of redundancy. That way when you log in no matter what your device, your progression won't be lost (and would also keeping you from artificially gaining additional gems/levels/cards etc). Im pretty sure that's the way it works but others will chime in. Is that what your asking?
