RailsSimpleBackupRestore

A simple backup/restore gem for Rails.

How it works:

SimpleBackup.backup:

• the database is dumped to db/data.yml with yaml_db
• a temporary zip file is created with:
  • config/backup_version
  • db/data.yml
  • all files listed in config/backup_files (each line being expanded with Dir[line_of_backup_files])
• the temporary file object is returned (it may already have been removed from disk, but you can #read it)

SimpleBackup.restore(file):

• check that the file is a ZIP and contains the same config/backup_version
• delete all files listed in config/backup_files (each line being expanded with Dir[line_of_backup_files])
• extract all files included in the ZIP file
• load the database dump

Add this line to your application's Gemfile:

gem 'rails_simple_backup_restore'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rails_simple_backup_restore

Create a file config/backup_version with, for example :

my rails app backup v1

Create a file config/backup_files with, for example :

public/system/**/*

In your controller:

def backup
  send_data SimpleBackup.backup.read, :filename => "Backup.zip"
end

def restore
  if params[:file]
    @done = true
    begin
      SimpleBackup.restore(params[:file])
      @success = true
    rescue => e
      @error = e.message
    end
  end
end

In the restore view (haml syntax, twitter bootstrap style):

- if @done
  - if @success
    .alert.alert-block.alert-success
      %p
        %strong Restauration done!
  - else
    .alert.alert-block.alert-error
      %p
        %strong= "An error occured during restore"
      %p
        = @error

= form_tag restore_path, :class => "form-horizontal", :multipart => true do
  %fieldset
    %legend Restore
    .control-group
      = label_tag :file, "Backup file", :class => "control-label"
      .controls
        = file_field_tag :file, :class => "input-file"
    .form-actions
      = submit_tag "Restore backup", :class => "btn btn-primary"
