Backup all branches for repository

By default git clone only main branch, find the way to get and save all branches.
Think about branches that can be useless and don't save them.

Another important concern is should we continue keeping orphaned branches? I mean the branches that were removed from the origin but are still existed in backup temporary location *

* temporary location - location where you've done git clone and do git fetch/git pull
