Various ddrescue (and other *rescue) programs are meant mainly for rescuing deleted or otherwise lost data -- they are very useful in carving artifacts of lost files and try to recover them into whole files. They act as a sort of digital forensic tools.
No, absolutely not. You are confusing tools.
"No"? --Hmm, might apply to some of the tools in the broad group... "Aboslutely not"? --This I think is a bit of an overstatement...
Radule, You might not like how *rescue work, but they are very focused tools designed to work with failing disks. Personally I use ewfacquire from libewf-tools as my first choice of tools for backing up a drive with minimal hardware failures. Ewfacquire defaults to trying each read twice before moving on. It also allows you to specify a block size of say 64KB for working parts of the drive, but step down to a single sector on failing sections. I always make "images". Those can be restored to a new drive. Ewfacquire does not do things like reverse reads, nor does it log progress such that future runs can work only on the failing sections of the drive. Gnu_ddrescue can do both of those. Thus if a drive has more than a couple bad sectors, I would use gnu_ddrescue instead. Fyi: I make my living doing computer forensics and I can assure you *rescue have nothing to do with data carving. Greg -- Sent from my Android phone with K-9 Mail.
