DVD burner with changer?


I am looking for a solution to back up large sets of data files to DVDs.
Data set may be in the order of 100 or 200 GB and would need to span
multiple DVD disks.

Right now I have to change disks manually when recording.

I am wondering if there exists a drive with disk autoloader / changer that I can preload with a stack of blank DVDs or at least several DVDs and leave it to burn the data.

Thanks for advise.
