biblatex: How to suppress back references for certain citations?

Question

When using BibTeX's standard citation commands, such as \cite, typically back references are generated (if enabled) in the bibliography pointing back to the place of citation. That's a nice feature. However, I would like to suppress these back references for certain citations, such as in figure or table captions. I don't want these to appear as back references in the bibliography.

I have found an identical question on comp.text.tex, it is unanswered there.

Set the boolean switch backtracker to false inside figure and table environments. (biblatex already does this for the ToC and similar lists.)

Note: \AtBeginEnvironment is an etoolbox command, and etoolbox is loaded by biblatex.

\documentclass{article}

\usepackage[backref=true]{biblatex}

\AtBeginEnvironment{figure}{\boolfalse{backtracker}}
\AtBeginEnvironment{table}{\boolfalse{backtracker}}

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@misc{A01,
  author = {Author, A.},
  year = {2001},
  title = {Alpha},
}
@misc{B02,
  author = {Buthor, B.},
  year = {2002},
  title = {Bravo},
}
\end{filecontents}

\addbibresource{\jobname.bib}

\begin{document}

Some text \autocite{A01}.

\begin{figure}
\centering
\rule{1cm}{1cm}
\caption{A figure \autocite{B02}}
\end{figure}

\printbibliography

\end{document}
