Intro

Backup your Github repos (because pushing code online isn't good enough).

Usage

Make sure to have an octo.edn file and an ssh access key from the current user account:

 $ octo sync octo.edn
 ...
 # Once done the git bundles are under (per user/org)
 $ ls ~/workspace/repos/narkisr/bundles
 aptly-docker.bundle
 basebox-packer.bundle

 # push to a remote backup like s3 using zbackup and rclone
 $ octo push octo.edn

 # restore backup from remote backup
 $ octo pull octo.edn

Configuration

The format of octo.edn is:

{
 :workspace "/home/ronen/workspace"
 :user "GITHUB USER"
 :token "PERSONAL ACCESS TOKEN"
 :repos [
    {:user "narkisr"
     :options {:fpm-barbecue {:branch "master"}} ; only backup a single branch
     :exclude []
     :layouts [["elm-*" "narkisr/elm"] [".*" "narkisr"]]
    }
    {:org "opskeleton"
     :exclude []
     :layouts [[".*" "opskeleton"]]
    }
  ]

 :push {
   :zbackup {
     :password-file ""
    }

   :rclone {
    :dest ""
   }
 }

}

Glossary:

• workspace: backup destination folder.
• user: github user.
• token: a personal access token.
• repos a collection of users/orgs we want to backup:
  • user/org: the user/org name that is backed up.
  • options: specific repo options (currently only selecting a single branch to back up).
  • exclude: which repos not to back up.
  • layouts: mapping from folder name regex match into destination folder, for example match all the repos with name elm-* prefix into narkisr/elm folder.
• push:
  • zbackup.password-file: password for zbackup (if using push/pull)
  • rclone.dest: A remote backup address

Backup lifecycle

Each repo:

1. Cloned into a bare repo using 'git clone --mirror'.
2. Exported to a single file using 'git bundle create'.
3. Incremented using 'git fetch remote'.

Install

Perquisites:

• JRE 1.8
• Git binary.
• rclone and zbackup (if using push/pull).
• Ubuntu (Should work on any Linux system but not tested).
