It copies data from one +file or block device (hard disc, cdrom, etc) to another, trying hard to +rescue data in case of read errors. + +The basic operation of ddrescue is fully automatic. That is, you don't +have to wait for an error, stop the program, read the log, run it in +reverse mode, etc. + +If you use the logfile feature of ddrescue, the data is rescued very +efficiently (only the needed blocks are read). Also you can interrupt +the rescue at any time and resume it later at the same point. + +Automatic merging of backups: If you have two or more damaged copies of +a file, cdrom, etc, and run ddrescue on all of them, one at a time, with +the same output file, you will probably obtain a complete and error-free +file. This is so because the probability of having damaged areas at the +same places on different input files is very low. Using the logfile, +only the needed blocks are read from the second and successive copies.") + (license "GPLv3+"))) |
