Butterbian

Butterbian is a Debian-based Linux distribution with out-of-the-box support for the Btrfs filesystem and pre-configured Timeshift, an application that takes incremental snapshots of the installed filesystem at regular intervals. These snapshots can be restored, directly from the GRUB menu, to undo all changes to the system. Butterbian boots into a themed Xfce desktop and uses the Calamares system installer. Besides Butterbian, the project also develops Butterknife, a command-line only live image with a text-mode system installer that provides more choices in terms of filesystems and window managers.
