Backupninja Module

Puppet Forge Build Status

Fork of the official riseuplabs/backupninja module as it is inactive.

This module helps you configure all of your backups with puppet, using backupninja!

! Upgrade notice !

If you were previously using this module, some pieces have changed, and you need to carefully change your use of them, or you will find your backups to be duplicated on your backup server. The important part that changed has to do with the rdiff-backup handler, if you weren't using that, you don't need to worry.

If you were, you will need to make sure you change all of your "$directory" parameters to be "$home" instead, and on your backupserver you will need to move all of your backups into "$home"/rdiff-backup. Previously, they were put in "$directory", which doubled as the home for the user that was created. This caused problems with rdiff-backup because of dot files and other things which were not part of any rdiff-backup.

Getting started

First you will need to import the module:

import "backupninja"

Configure your backup server

Now you will need to configure a backup server by adding the following to your node definition for that server:

include backupninja::server

By configuring a backupninja::server, this module will automatically create sandboxed users on the server for each client for their backups.

You may also want to set some variables on your backup server, such as:

$backupdir = "/backups"

Configure your backup clients

The backupninja package and the necessary backup software will be installed automatically when you include any of the different handlers (as long as you are not handling it elsewhere in your manifests), for example:

include backupninja::client::rdiff_backup

In this case, the module will make sure that the backupninja package and the required rdiff-backup package are 'installed'/'present' (using puppet's ensure parameter language). If you need to specify a specific version of either backupninja itself, or the specific programs that the handler class installs, you can specify the version you need installed by providing a variable, for example:

$backupninja_ensure_version = "0.9.7bpo50+1" $rdiff_backup_ensure_version = "1.2.5-1bpo40+1" $rsync_ensure_version = "3.0.6-1bpo50+1" $duplicity_ensure_version = "0.6.04-1bpo50+1" $debconf_utils_ensure_version = "1.5.28" $hwinfo_ensure_version = "16.0-2"

If you do not specify these variables the default 'installed/present' version will be installed when you include this class.

Configuring handlers

Depending on which backup method you want to use on your client, you can simply specify some configuration options for that handler that are necessary for your client.

Each handler has its own configuration options necessary to make it work, each of those are available as puppet parameters. You can see the handler documentation, or look at the handler puppet files included in this module to see your different options.

Included below are some configuration examples for different handlers.

  • An example mysql handler configuration:

backupninja::mysql { all_databases: user => root, backupdir => '/var/backups', compress => true, sqldump => true }

  • An example rdiff-backup handler configuration:

backupninja::rdiff { backup_all: directory => '/media/backupdisk', include => ['/var/backups', '/home', '/var/lib/dpkg/status'], exclude => '/home/*/.gnupg' }

  • A remote rdiff-backup handler:

    backupninja::rdiff { "main": host => "", type => "remote", directory => "/backup/$fqdn", user => "backup-$hostname", }

Configuring backupninja itself

You may wish to configure backupninja itself. You can do that by doing the following, and the /etc/backupninja.conf will be managed by puppet, all the backupninja configuration options are available, you can find them inside this module as well.

For example:

backupninja::config { conf: loglvl => 3, usecolors => false, reportsuccess => false, reportwarning => true; }

Nagios alerts about backup freshness

If you set the $nagios_server variable to be the name of your nagios server, then a passive nagios service gets setup so that the backup server pushes checks, via a cronjob that calls /usr/local/bin/, to the nagios server to alert about relative backup freshness.

To use this feature a few pre-requisites are necessary:

. configure nsca on your backup server (not done via puppet yet) . configure nsca on your nagios server (not done via puppet yet) . server backup directories are named after their $fqdn . using nagios2 module, nagios/nagios3 modules/nativetypes not supported yet . using a nagios puppet module that can create passive service checks . backups must be under $home/dup, $home/rdiff-backup depending on method . $nagios_server must be set before the class is included

You can’t perform that action at this time.
