`ddrescue` a directory

README.md

ddrfind - ddrescue on a directory

A non-recursive approach to using ddrescue on a directory.

Chances are, if you have a currupted set of memory, it's not just a few files. It's probably a whole disk. Wanna save it? You can use ddrescue, but that doesn't work on directories, only files. If you want to use it on a whole big directory, you'll need to do each file one by one. That's exactly what this script does.

Installation

$ fish ddrfind.fish

ddrfind.fish

function ddrfind --description 'ddrescue on a directory (using find)'
  if not test -d $argv[1]; or set -q $argv[2]
    echo "Usage: ddrfind <input-dir> <output-dir>"
    exit 1
  end

  set -l dest (pwd)"/"$argv[2]

  mkdir -p $dest

  cd $argv[1]
  for file in (find . -name "*")
    if test -d $file
      # make a new sub-directory
      mkdir -p $dest"/"$file
    else
      # rescue the file
      echo $dest"/"$file
      ddrescue $file $dest"/"$file > /dev/null
    end
  end
  cd -
end

funcsave ddrfind

Hey. This is exactly what I was looking for but ran into a problem. Never used fish or ddrescue before...
I try to copy a folder from the failing drive to another disk using:
ddrfind '/media/[user]/xyz/! DL Save/2022-12/' /media/[user]/Backups/WD-Updates/

But everytime I try it, the script keeps creating "media/[user]/Backups/WD-Updates/" as new folders inside the source folder (2022-12) instead of on the backup drive and starts copying to the already damaged drive...

I know, I must be missing something pretty simple here, but I just can't figure out how to route the output to the new drive...

I also had these issues. There is something wrong with the paths of this script. I think you had to use the target path relative to the source directory. Like ddrfind /media/failingdrive/important ../../gooddrive/rescued.

Thank you so much, it works! I was trying to get this working for hours now before bothering someone else.
