Alright. I added another clause to the copy statement to avoid copying anything with a number at the end of it (or so I am led to believe).

It returns a zero if no number is found in the title. I have yet to test if it work with world names such as: world2mine
It filters out world2 or in the case of the backup script: world-2011-11-11-11.11
