       dd_rescue - copies data from one file (or block device) to another


       dd_rescue [options] infile outfile


       This  manual page documents briefly the dd_rescue command.  This manual
       page was written for  the  Debian  distribution  because  the  original
       program does not have a manual page.

       dd_rescue  is  a program that copies data from one file or block device
       to another, it is a  tool  to  help  you  to  save  data  from  crashed
       partition.   It  tries  to  read and if it fails it will go on with the
       next sectors, where tools like dd will fail. If the copying process  is
       interrupted  by  the  user  it  is possible to continue at any position
       later.  It can copy backwards.
