Example of a script for backing up Jenkins config in git.

First (and foremost) Thanks for this.

I realize it is an old post, so I'll completely understand if you don't reply. Nevertheless, I would appreciate:

  1. confirmation that root_dir is just any (empty) directory where I choose to store the backup repository that this script creates for my server's jenkins config

  2. for a non-standard jenkins install (i.e. there's no /var/lib/jenkins on my jenkins server), how could I determine the equivalent of jerkins_master? Is there a particular top-level directory entry I can look for? (i.e. is it most-likely the directory containing my jenkins.war?)

and, last, but not least:
3) what steps do you follow to restore jenkins (i.e. if/when your ec2 instance dies)?

eh, I don't think it is good enough, so I fork it to my repos, and improve it plus my mind.

Thanks for all your sharing. Wonder if there is a way to backup a specific plan/project and how to retrieve it?
