1 Like dd, dd_rescue does copy data from one file or block device
2 to another.
3 You can specify file positions (called seek and Skip in dd).
4 There are several differences:
6 * dd_rescue does not provide character conversions.
7 * The command syntax is different. Call dd_rescue -h.
8 * dd_rescue does not abort on errors on the input file,
9 unless you specify a maximum error number. Then dd_rescue
10 will abort when this number is reached.
11 * dd_rescue does not truncate the output file, unless asked to.
12 * You can tell dd_rescue to start from the end of a file and
13 move backwards.
14 * It uses two block sizes, a large (soft) block size and a small
15 (hard) block size. In case of errors, the size falls back to
16 the small one and is promoted again after a while without errors.
