A positive first post! backup batch file

This is a positive first post.
It’s a batch file I wrote to do some backup stuff.
It has only been tested on XP, but will almost surely work on Win2k (ooooh!) not sure about Win9x, Me, 3.x, DOS, etc, etc.
I’d love to make it smarter, and will no doubt post some moanings about things I can’t do in the coming days, but this is a positive start :)

ps. Keep in mind that as far as batch files go, I’m a beginning beginner, who’s like just begun…
