SYNOPSIS
dd_rescue [options] infile outfile
DESCRIPTION
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.
