NAME

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

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.
