Archive Large files to DVD - span?

"You best option is really the split archives using 7zip. It's simple, easy, and will use up every last bit of each DVD (excluding overburning). This way you'll also gain a extra space if the content isn't already compressed.

On that note, if the content is already compressed you might want to turn off compression or use lower compression settings to save some CPU time since you won't gain much space from compressing compressed content.

I recently backed up 1.36 TB of media to many DVDs using 7zip."
