K9Copy facilitates several methods for backing up a DVD and uses libdvdcss to circumvent CSS copy protection if installed.

[3] The software enables direct backup of a single layer DVD-5 provided the user's computer has a DVD recorder.

The interface allows a user to explicitly retain or discard any content from the original disc such as video titles, audio tracks, subtitles and the DVD menu.

All content selected for backup is compressed to a configurable target size (4400 MB by default) and stored on the user's hard drive as either an ISO image file or a DVD VIDEO TS folder.

K9Copy can either transfer the backup data to blank DVD±R media itself or utilize external DVD authoring software such as K3b for this task.
