This is a video of an rescue ISO I made for folk using qt4-fsarchiver backup on LMDE 16 months ago and it still gets loads of downloads, last month over 130 but I also included the first saline-backup script which I demo on this video.
What I really liked about it was you could point at any Debian OS partition on your machine and create a backup file, maybe you could do the same to create a live CD/DVD?
Anthony had a mishap with it so removed it with his next version and when I ask about having it back it was another "It's never going to happen" but that was a very powerful and useful function and I've always missed it.
