useful advice on best approach to autosave

This is a non-code answer to your question.

There is no good way to do this. You can make the updates based on X amount of words, or you can make it every character, or even every second. The problem is that is tons of connections.
It is resource and bandwidth heavy, requiring you to use an internet connection every time you want to save. Then you have the problem regarding what you want to send to the database?
How do you check to see what the database already has? Do you just resend the entire thing?
These are all questions that you must answer. But essentially it is the same as it is now... except you have >some sort of code (as i mentioned character change, word change, time change) and will then push either >the entire text / field. or just what it doesn't have into the database.

So there is no GOOD way to do it. If I had to do it, I would store the info locally. Then lets say once every 30 sec, update it and send only the changed characters to the database.
