title: How to stop Bitbucket and Git LFS file Duplication
body: <p>I am using Bitbucket and Git LFS to store binary files for a project I am working on. What I have found is that i very quickly run out of storage and the cause seems to be that each time i push a change LFS will add a new file to the server instead of overwriting the file. I have a particular file that is around 400 MB and if I push i can see it in file storage more than once.</p>
  
  <p>Is there a way to stop this behavior and instead overwrite the file, or is there an easy process to purge the old files before pushing?</p>
