Overview

This module installs and configures the Github Enterprise Backup Utilities.

Module Description

The fine folks at Github have a set of tools for backing up Github Enterprise installations. This tool is available in a git repository.

This module installs this tools and keeps it up to date. It creates the needed configuration files as well as the cronjobs that run the backups. It also provides sane default configurations to make backups more reliable.

Setup

What ghebackups affects

  • A git repository will be installed and kept up to date.
  • Cronjobs to run the backups will be added to the system.

Setup Requirements

  • This module requires that rsync be installed to properly run.
  • The backup user's SSH key needs to be installed on the GHE instance to run.

Beginning with ghebackups

This module is rather simple to use- simply include the 'ghebackups' file and the default settings should work (assuming your local GHE instance is named 'github' and dns is working).

class { 'ghebackups': }

A more complete example including custom hostname would look like this.

class { 'ghebackups':
  ghe_hostname      => 'github.example.net',
  ghe_data_dir      => '/backups/github',
  ghe_num_snapshots => 72,
}
