I don't code seriously myself so I won't be able to review your Python
code either :) But as u pointed out, Tails Installer is written in
Python and if we ever want to propose a "clone everything" feature, I
think it should be integrated in Tails Installer.

If you're interested in plugging this in the current code [1] that would
be awesome. But as we haven't really finished the design decision around
the backup scenarios, I can't promise anything regarding it's official
acceptance yet.

I also think there's value in both methods. But we also prefer having
one tool for one thing and avoid overlapping features. That's for me one
of the main issue regarding the design of the backup tool:

- "Clone everything" allows for a bootable backup of literally
everything in persistence, including files owed by root.
- Deja-Dup allows incremental and distant backups with a very good
integration on the desktop but only for the files owned by `amnesia`.

I wonder whether we could have to best of both worlds in a single tool,
but I haven't taken the time to investigate this in depth really. If
it's impossible, then I might propose to have both options.

Sure :)
