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