Restore my configuration after hardware reset

Is there a way (really fast or easy way) to restore my configuration, or at least my script which will do all needed after a hardware reset ?? (Pressing to Reset button by user on the Router box)

I saw methods with default script stored via netinstall app. But it is ok, if we are talking about one, two boxes.
I need something more fast, to say, configure 50-80 router boards and be sure, that in case of some corruption, end user may reset current settings and restore default ones, which includes my scripts or so..

At least would be nice to have some autorun script method, say, just coppy script to router or to connected USB storage and after restart execute it.

Thanks for all your tips!

Nobody needed it ?
