Backup Cookbook

This cookbook automates deploying the backup gem and the configuration of any models you may want. With a little work you can backup everything using this cookbook as the framework.

Requirements

packages

• ruby - ruby is required for the backup gem to be installed. This can be provided either via chef or via other means.
• libxml2-dev
• libxslt1-dev

Resources and Providers

This cookbook provides three resources and corresponding providers.

install.rb

Install or Remove the backup gem with this resource.

Actions:

• install - installs the backup gem
• remove - removes the backup gem

generate_config.rb

Generate a configuration file for the backup gem with this resource.

Actions:

• setup - sets up a basic config.rb for the backup gem
• remove - removes the base directory for the backup gem and everything underneath it.

Usage

This cookbook is intended to be a framework to help backup your systems. Some examples below:

MongoDB

backup_install node.name
backup_generate_config node.name
gem_package "fog" do  
    version "~> 1.4.0"  
  end  
backup_generate_model "mongodb" do  
  description "Our shard"  
  backup_type "database"  
  database_type "MongoDB"  
  split_into_chunks_of 2048  
  store_with({"engine" => "S3", "settings" => { "s3.access_key_id" => "example", "s3.secret_access_key" => "sample", "s3.region" => "us-east-1", "s3.bucket" => "sample", "s3.path" => "/", "s3.keep" => 10 } } )  
  options({"db.host" => "\"localhost\"", "db.lock" => true})  
  mailto "some@example.com"  
  cron_path "/bin:/usr/bin:/usr/local/bin"
  tmp_path "/mnt/backups"
  cron_log "/var/log/backups.log"
  action :backup  
end  

PostgreSQL

backup_install node.name  
backup_generate_config node.name  
gem_package "fog" do  
  version "~> 1.4.0"  
end  
backup_generate_model "pg" do  
  description "backup of postgres"  
  backup_type "database"  
  database_type "PostgreSQL"  
  split_into_chunks_of 2048  
  store_with({"engine" => "S3", "settings" => { "s3.access_key_id" => "sample", "s3.secret_access_key" => "sample", "s3.region" => "us-east-1", "s3.bucket" => "sample", "s3.path" => "/", "s3.keep" => 10 } } )
  options({"db.name" => "\"postgres\"", "db.username" => "\"postgres\"", "db.password" => "\"somepassword\"", "db.host" => "\"localhost\"" })  
  mailto "sample@example.com"  
  action :backup  
  end

Archiving files to S3

backup_install node.name   
backup_generate_config node.name  
gem_package "fog" do  
  version "~> 1.4.0"  
end  
backup_generate_model "home" do  
  description "backup of /home"  
  backup_type "archive"  
  split_into_chunks_of 250  
  store_with({"engine" => "S3", "settings" => { "s3.access_key_id" => "sample", "s3.secret_access_key" => "sample", "s3.region" => "us-east-1", "s3.bucket" => "sample", "s3.path" => "/", "s3.keep" => 10 } } )  
  options({"add" => ["/home/","/root/"], "exclude" => ["/home/tmp"], "tar_options" => "-p"})  
  mailto "sample@example.com"  
  action :backup  
end  

It is possible to load the settings in an role or an data bag or leave the settings in a recipe.
