I'm trying to create a script to automatically make copies to my backup disk.

The thing is that I want the script to check if the file is already in the backup disk in order to only copy files that are missing.

What I have done already:
I have no idea of what commands to use for this (or where to look for them). Somebody suggested glob and s/modules/facilities.
I have found glob but not the other one (I've searched CPAN but I'm not entirely sure I did it the right way). I also googled it but came up with nothing, then again I have such a faint idea of what to look for that it is possible i didn't look for the right terms.

Any help would be really appreciated.
