Backshift is a deduplicating (variable-sized, content-based blocks), compressing (xz or bz2) backup program. Full saves and incrementals are pretty indistinct other than the amount of data transmitted, somewhat like with "rsync --link-dest" but without the huge number of hardlinks. It also de-duplicates large file content at a granularity of about 2 megabytes on average; there tends to be a unique copy of each file with size less than around 2 megabytes on average.

K9Copy facilitates several methods for backing up a DVD. The software enables direct backup of a single layer DVD-5, provided the user's computer has a DVD recorder. Likewise, direct backup of a dual layer DVD-9 is possible with a dual layer DVD recorder. K9Copy is also able to fit the contents of a dual layer DVD-9 onto a single layer DVD-5. 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 or utilize external DVD authoring software such as K3b for this task. Furthermore, an ISO image file produced by K9Copy can be recorded to DVD by any software on any platform capable of recording ISO images to disc. It can also back up a DVD to a video file (such as MPEG-4).
