Backup batch file using NeroCmd

Here at work we want to use NeroCmd to create a batch file that will automaticly back up data from a directory to a CD. We dont know wether the people would use a CDR or CD-RW (though we will prob enforce the idea of a CDRW) but we want the cd to hold backup data for at least the last week(sometimes the data gets big…).

how would i do this? It would be run by a shortcut on the user’s desktop.
