 The \textbf{where=} option is simple, but not very powerful. With file
 relocation, bacula can restore a file in the same directory, but with a

+\subsection{RegexWhere format}
+
+The format is very close to that used by sed or Perl (\texttt{s/replace this/by
+  that/}) operator. A valid regexwhere expression have 3 fields :
+\begin{itemize}
+\item a search expression (with optionnal submatch)
+\item a replacement expression (with optionnal backreferences \$1 to \$9)
+\item a set of search options (only case-insensitive ``i'' at this time)
+\end{itemize}
+
+Each fields is delimited by a separator chosen by the user at the beginning
+expression. The separator can be :
+\begin{verbatim}
+<separator-keyword> = / ! ; % : , ~ # = &
+\end{verbatim}
+
+You can use several expressions separated by a comma.
+
+\subsection*{Examples}
+
+\begin{tabular}{|c|c|c|l}
+\hline
+Orignal filename & Computed filename  & RegexWhere  & Comments \\
+\hline
+\hline
+\texttt{c:/system.ini} & \texttt{c:/system.old.ini} & \texttt{/.ini\$/.old.ini/} & use \$ as end of filename\\
+\hline
+\texttt{/prod/u01/pdata/} & \texttt{/rect/u01/rdata}  & \texttt{/prod/rect/,/pdata/rdata/} & using two regexp\\
+\hline
+\texttt{/prod/u01/pdata/} & \texttt{/rect/u01/rdata}  & \texttt{!/prod/!/rect/!,/pdata/rdata/} & using \texttt{!} instead of \texttt{/}\\
