dd_rescue copies data from one file or block device
to another. It is intended for error recovery, so, by
default, it doesn't abort on errors, and doesn't
truncate the output file. It uses large block sizes to
quicken the copying, but falls back to small blocks
upon encountering errors. It produces reports that
allow you to keep track of bad blocks.
Release Notes: The -p/–preserve option now also copies extended attributes (including ACLs) if there are any. Many checks and test cases have been added to make check. Half-empty blocks are now detected now in sparse detection. If copying with an odd file offset, the odd-sized write will be done first so that further accesses should be better aligned, which should help with performance (and optionally sparse detection).
