A Git branch can be reset to exactly match the remote branch with the following commands:

1. Save the state of your current branch in another branch, named `my-backup`,in case something goes wrong:
   ```xml
   git commit -a -m "Backup."
   git branch my-backup
   ```
2. Fetch the remote branch and set your branch to match it:

   ```xml
   git fetch origin
   git reset --hard origin/master
   ```



> This example assumes that the remote repo's name is "origin" and that the branch named "master", ​in the remote repo, matches the currently checked-out branch in your local repo.
