Single folder burner in batch mode?

We’re storing a client DB in a single folder and are hiding the Windows UI from the user. We want the user to be able to insert a single CD, then have it auto-run an (unknown) burner that’ll backup the DB folder to as many optical disks as it takes to complete the task.

Do you know of any such product, prefereably open-source? We could even use a Linux product, I suppose, provided the Linux OS is small enough to fit in RAM along wit the burner utility (given that the initiating optical disk has to be swapped out for blank media).

Thnaks!
