14 GNU ddrescue is a data recovery tool. It copies data from one file or block
15 device (hard disc, cdrom, etc) to another, trying hard to rescue data in
16 case of read errors.
18 Ddrescue does not truncate the output file if not asked to. So, every time
19 you run it on the same output file, it tries to fill in the gaps.
21 The basic operation of ddrescue is fully automatic. That is, you don't have
22 to wait for an error, stop the program, read the log, run it in reverse mode.
24 If you use the logfile feature of ddrescue, the data is rescued very
25 efficiently (only the needed blocks are read). Also you can interrupt the
26 rescue at any time and resume it later at the same point.
28 Automatic merging of backups: If you have two or more damaged copies of a file,
29 cdrom, etc, and run ddrescue on all of them, one at a time, with the same
30 output file, you will probably obtain a complete and error-free file. This is
31 so because the probability of having damaged areas at the same places on
32 different input files is very low. Using the logfile, only the needed blocks
33 are read from the second and successive copies.
35 The logfile is periodically saved to disc. So in case of a crash you can
36 resume the rescue with little recopying.
38 Also, the same logfile can be used for multiple commands that copy different
39 areas of the file, and for multiple recovery attempts over different subsets.
41 Ddrescue aligns its I/O buffer to the sector size so that it can be used to
42 read from raw devices. For efficiency reasons, also aligns it to the memory
43 page size if page size is a multiple of sector size.
