Today a colleague of mine wanted to export a single folder from a git repository to a tar.gz archive. This is how to export git subfolder to archive:

git archive --remote='git@bitbucket.org:sheldon/ask-sheldon.com.git' master path/to/file/or/folder/in/repo --format=tar.gz > archived_folder.tar.gz

With this snippet the git repository folder path/to/file/or/folder/in/repo is exported to the archive file archived_folder.tar.gz. The archive will be cleared of all git information (no .git* files).
