Optimising Backup?

Is it possible to have Comodo Backup manage a backup to DVDs so that I can simply select multiple files, and then be asked to insert new DVDs as required, optimising the files on to the DVDs for use of space, but without breaking files?

I ask this because I have used WinZip to do this, but it keeps asking for other DVDs when you try to recall any file.

Thanks for any info
