+title: "Recoving de-duplicated git repositories"

+I have a number of software projects in a single directory, using `git` for version control which is shared across most of my computers using `syncthing`.
+
+Late one night, I wanted to de-duplicate a folder full of files I'd been working on over the course of a few weeks. I'd work through a directory then as part of my 'completing' the work, would de-duplicate it using `jdupes` to ensure no files were duplicated. I'm sure you can see where this is going.
+
+As part of my workflow, I was navigating directories, tapping the up arrow to repeat my last command and hitting enter with reckless abandon. I noted the command took a little longer than usual and immediately realised what I'd done. I went to assess the damage, when browsing using git, cgit, or even the github desktop client, all my repositories were broken except for a single bare repository.
+
+The first thing to do is to find any potentially affected directories. This can simply be done via `find . -type d -name '.git'`. As what was deleted will only ever be duplicated content, you should be able to rebuild these repositories quite easily with the following:
+
+```
+cd affected-project
+mv ".git" ".gitcontents"
+git init
+rsync --remove-source-files -av ".gitcontents" ".git"
+find ".gitcontents" -empty -delete
+```
+
+Which should get you up and working again.
+
+The moral of the story is to keep a backup, and then make a backup of your backup (just in case).
