(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.")
