I saw there were some discussions back then (https://redmine.replicant.us/boards/3/topics/14338?r=14448) but we still do not have a solution to backup asap in the process of installing Replicant (ideal is before installation, but juste after recovery could be an acceptable worst-case).

Since I am convinced by Replicant, I am pretty sure I want to install it and not going back stock android but visitors could have a different though.
