| Hans-G?nter@24472 | 1 Like dd, dd_rescue does copy data from one file or block device |
| Hans-G?nter@24472 | 2 to another. |
| Hans-G?nter@24472 | 3 You can specify file positions (called seek and Skip in dd). |
| Hans-G?nter@24472 | 4 There are several differences: |
| Hans-G?nter@24472 | 5 |
| Hans-G?nter@24472 | 6 * dd_rescue does not provide character conversions. |
| Hans-G?nter@24472 | 7 * The command syntax is different. Call dd_rescue -h. |
| Hans-G?nter@24472 | 8 * dd_rescue does not abort on errors on the input file, |
| Hans-G?nter@24472 | 9 unless you specify a maximum error number. Then dd_rescue |
| Hans-G?nter@24472 | 10 will abort when this number is reached. |
| Hans-G?nter@24472 | 11 * dd_rescue does not truncate the output file, unless asked to. |
| Hans-G?nter@24472 | 12 * You can tell dd_rescue to start from the end of a file and |
| Hans-G?nter@24472 | 13 move backwards. |
| Hans-G?nter@24472 | 14 * It uses two block sizes, a large (soft) block size and a small |
| Hans-G?nter@24472 | 15 (hard) block size. In case of errors, the size falls back to |
| Hans-G?nter@24472 | 16 the small one and is promoted again after a while without errors. |
