not sure having to write stuff any time you do even the smallest thing on your table is more reasonable of taking the pain to write (or ask friends to help you writing) a couple of bash scripts that will do the job forever. But then again, this is true if and only if she is the one and only user who can create data.

That probably isn't a reasonable solution, considering the OP mentioned that she was not a professional DBA. Setting up a hot/warm standby, failing over, resetting the slave from the new master, lather, rinse, repeat  is certainly scriptable but doesn't seem like the best option here.

I don't know of any commercial solutions, but writing some code might be required. Synchronizing data isn't that difficult, but synchronizing changes to database table structure will be a bit tricky,
