multicd provides an easy way to backup a large number of files to multiple CDs or DVDs. Give multicd the files/directories you want backed up and it will create as many CDs or DVDs as it needs to, prompting the user to put in a new disc whenever needed. It can be configured to run in a multi-threading mode, where it will burn one image to a disc while it is copying files to another image. This feature can be disabled for slower machines.
