Computer are REALLY good at repetive tasks.  All it takes is a little work on your part.
A batch file with something like the following would automate it.
	Code:
	if not exists backup md backup
copy *.txt backup\
copy *.exe backup\
copy *.dll backup\
... ect for what ever you wish to backup
 I didn't try to check for syntax errors, but that is one way to make it easy.
