(synopsis "GNU ddrescue, a data recovery tool")
(description
"GNU ddrescue is a data recovery tool. 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.")
