Rescueing files from lost+found

Posted in Computers, PlanetDebian at 18:49 UTC (+0000) by sven

Oh well, I tried to search for it but failed miserably, so I’m blogging about it hoping the original author might read my post on planet.debian.org (where I read the original post):

A friend of mine might need exactly the sort of scripts someone posted here:

  1. Creating a list of file checksum+pathname/filename
  2. Reading files from lost+found and moving them to their original filename by identifying from the list in (1)

However, I can’t recall who posted about this, and don’t want to do the same work again. Please, Dear Lazyweb, help me ;-)

    Notice the little search box on the right on planet.d.o. Ingo Juergensmann, FWIW.

    Mind you, planet debian has a search function.

    Searching for “lost+found” on
    http://planet-search.steve.org.uk/cgi-bin/planet-search
    shows several hits this is the most promising:

    Planet Debian has a search bar, at the top right under the Debian logo. Typing “lost+found” into it gives the results you want right after your post. :)

    I think this is what you are looking for: http://blog.windfluechter.net/index.php?/archives/307-Automatically-restore-files-from-lost+found-improved.html

    That was me…

    Sadly, to be honest, my scripts are not that useful, when the files are already located in lost+found. You’ll need one part of the scripts to generate the checksum file regularly (cronjob) to be able to recover files from lost+found with the second script when it’s needed.

    See http://blog.windfluechter.net/index.php?/archives/307-Automatically-restore-files-from-lost+found-improved.html for more details!

    Thanks for the help.
    Ingo: I know, but your scripts are a really nice help when it comes to preventing the problem he has from appearing again.
    If anyone is interested:
    The problem for him was the following:
    He had lots of files kept in a single directory. All those files were on backup.
    Now he started sorting the files according to their content and context. When finished (well, a short while after he was finished, but before the next regular backup), he accidentally deleted the sorted tree.
    With recover (or e2undel), he recovered parts of the sorted stuff, but most landed in some directory named after their inodes (much like e2fsck names them when it finds lost files). So, since your (Ingo’s) script could be run far more often than a full fledged backup, it might help him if something similar happens again in the future.

    I already provided him with the needed info to find files which where not recovered by “recover”.

    Also, I should have known that the search function on planet.d.o is not limited to the posts currently shown on the page. Stupid me… ;-)

    Yes, it should be suitable for the purpose of not let that happen again.

    Truely, I wonder why there exists such a tool already doesn’t, because the idea is quite simple. Maybe someone want to implement it in a clean way?
    Anyway, I hope your friend finds my scripts useful in the meantime! :-)
