I am sure somebody will find a tool for you, but as a quick solution you
may consider running find -ls and store its output and then tar
everything that has been modified since last tar.
Having list of files you will be able to find out which files have been
deleted, and having these files in some previously made tarball you will
be able to restore them when needed.
Rsync would not save you the deleted files.

You just need some work to fit this simple thing to your own needs. :)
