longDescription =
|
|
'' 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.
