One of the ideas I've wanted to implement, but haven't had time, is to
cooperate with the system package database for backing things up.
Walk the file-system and check them against the package database.  If the
file is an unmodified copy of something provided by the system packages,
ignore it.  Otherwise, save it.  You'd also need to save a list of packages
on the system.

Then, recovery would just involve doing a re-install from the normal
channels, making sure the same set of packages was installed, and then
de-archive all the files that were saved.
